Estimated study time: 45 minutes
These Deviation from ideal mental health A-Level Psychology revision notes explain how psychological difficulty may be identified through the absence of positive characteristics associated with healthy living. Jahoda proposed criteria including positive self-attitudes, personal growth, autonomy, accurate perception of reality and the ability to cope with life’s demands. This provides a broad and positive definition of mental health, but the ideal is so demanding that most people would fail to meet every criterion. Cultural values may also influence which qualities are treated as ideal.
Deviation from ideal mental health is one of the four definitions required by the AQA specification.

Deviation from ideal mental health A-Level Psychology revision overview
Deviation from ideal mental health defines psychological difficulty as the absence of characteristics associated with positive mental health.
Rather than asking:
“What signs of psychological illness does this person display?”
the definition asks:
“To what extent does this person possess the qualities associated with psychological wellbeing?”
A person may be identified as deviating from ideal mental health when they do not meet one or more positive criteria.
The more criteria that are absent, the greater the possible concern.
This definition therefore describes mental health in terms of a continuum.
At one end, a person may meet many positive criteria.
At the other end, a person may lack several features associated with healthy psychological functioning.
A positive definition of mental health
The other definitions focus mainly on possible problems:
Statistical rarity asks whether behaviour is uncommon.
Social and cultural expectations asks whether behaviour violates accepted standards.
Difficulty managing everyday life asks whether the person can cope with ordinary demands.
Deviation from ideal mental health takes a different approach.
It identifies qualities associated with:
Psychological growth.
Independence.
Self-acceptance.
Coping.
Accurate thinking.
Successful relationships.
Effective engagement with the environment.
The absence of psychological illness is not considered sufficient.
A person may have no diagnosed condition but still:
Feel unable to develop.
Depend entirely on other people’s approval.
Have a very negative view of themselves.
Struggle to cope with ordinary stress.
Lack meaningful goals or relationships.
Mental health compared with physical health
The definition is partly modelled on positive approaches to physical health.
Physical health is not defined only as the absence of a disease.
It may also involve:
Effective bodily functioning.
Strength.
Energy.
Appropriate nutrition.
The ability to carry out activities.
Similarly, psychological health may involve more than the absence of symptoms.
It may include positive capacities such as:
Autonomy.
Personal growth.
Emotional stability.
Adaptability.
A positive but realistic self-view.
However, mental health may be more difficult to define and measure than physical health.
Jahoda’s criteria for ideal mental health
Psychologist Marie Jahoda proposed several characteristics associated with optimal psychological functioning.
The six commonly used criteria are:
Positive attitudes towards the self.
Self-actualisation and personal growth.
Integration and resistance to stress.
Autonomy.
Accurate perception of reality.
Environmental mastery.
AQA mark-scheme guidance accepts criteria including positive self-attitudes, working towards self-actualisation, coping with stress, accurate perception of reality, independence and the ability to adapt.
Summary table
Jahoda’s criterion | Central idea | Possible evidence |
Positive self-attitudes | Accepting and valuing oneself realistically | Healthy self-esteem and stable identity |
Self-actualisation | Developing one’s abilities and potential | Working towards meaningful goals |
Integration | Maintaining psychological balance and coping with stress | Emotions and behaviour remain reasonably coordinated |
Autonomy | Making independent decisions | Behaviour is not controlled entirely by social pressure |
Accurate perception of reality | Interpreting oneself and the world realistically | Judgements are not heavily distorted |
Environmental mastery | Managing life, work and relationships effectively | Adapting to changing circumstances |
Positive attitudes towards the self
What are positive self-attitudes?
Positive self-attitudes involve having a reasonably accepting and realistic view of oneself.
This may include:
Healthy self-esteem.
Self-respect.
A stable sense of identity.
Acceptance of strengths and weaknesses.
Confidence that is grounded in reality.
Feeling worthy of care and respect.
A person does not need to believe that they are perfect.
Ideal mental health involves a balanced self-view rather than:
Constant self-criticism.
Unrealistically high self-praise.
A complete dependence on other people’s approval.
A distorted view of one’s appearance or abilities.
Self-acceptance
Self-acceptance means recognising personal strengths and limitations without treating every weakness as evidence of worthlessness.
A person with self-acceptance might think:
“I made a mistake, but one mistake does not mean I am useless.”
A person with a severely negative self-attitude might think:
“I made a mistake, so I am a complete failure.”
The first response evaluates the event.
The second response turns the event into a global judgement about the self.
Realistic rather than constantly positive
Positive self-attitudes do not require a person to feel confident all the time.
Everyone may experience:
Embarrassment.
Self-doubt.
Regret.
Disappointment.
Dissatisfaction.
The criterion concerns the person’s broader self-concept.
A temporary period of low confidence does not necessarily show serious deviation from ideal mental health.
Example
Harriet receives a lower grade than expected.
She feels disappointed but recognises that:
One result does not define her.
She has strengths in other areas.
She can change her revision strategy.
She remains capable of improvement.
This demonstrates a relatively positive and realistic self-attitude.
Example of possible deviation
Lewis receives positive feedback from friends but continues to describe himself as worthless and believes that nobody could genuinely value him.
This may indicate deviation because:
His self-attitude is persistently negative.
His interpretation does not match the available feedback.
He appears unable to recognise positive personal qualities.
Self-actualisation and personal growth
What is self-actualisation?
Self-actualisation means developing one’s abilities and working towards fulfilling one’s potential.
This can involve:
Setting meaningful goals.
Learning.
Developing skills.
Becoming more capable.
Expressing creativity.
Seeking purposeful activities.
Growing through experience.
The criterion does not require everyone to achieve fame, wealth or exceptional success.
Self-actualisation is individual.
One person may work towards potential through:
Education.
Another may do so through:
Parenting.
Artistic work.
Employment.
Sport.
Community activity.
Personal relationships.
Personal growth
Personal growth involves continuing psychological development.
A person may:
Learn from mistakes.
Become more emotionally aware.
Develop better coping strategies.
Improve relationships.
Take on new responsibilities.
Adjust goals when circumstances change.
The person is not psychologically fixed.
They can adapt and develop.
Meaningful goals
Ideal mental health involves having some sense of direction or purpose.
Goals may be:
Short term.
Long term.
Personal.
Educational.
Social.
Creative.
Occupational.
The goals do not need to match society’s conventional expectations.
What matters is that they are meaningful to the individual and contribute to development.
Applying self-actualisation
Maya enjoys writing but has stopped every creative activity because she believes she could never produce anything worthwhile.
She also refuses opportunities to learn new skills.
This could represent deviation from ideal mental health because:
She is not working towards her potential.
Her negative self-view restricts personal growth.
She is withdrawing from activities she values.
However, choosing not to follow one particular talent does not automatically indicate poor mental health.
A person may reasonably prioritise other goals.
Barriers to self-actualisation
A failure to develop potential may result from:
Poverty.
Discrimination.
Illness.
Caring responsibilities.
Lack of educational opportunities.
Unsafe living conditions.
It would be unfair to interpret every blocked opportunity as an individual psychological failure.
The person may be motivated and psychologically healthy but unable to access the necessary resources.
Integration and resistance to stress
What is integration?
Integration refers to psychological balance.
A well-integrated person has thoughts, emotions and behaviour that are reasonably coordinated rather than being in constant conflict.
Integration may involve:
Managing competing demands.
Maintaining a coherent identity.
Regulating emotions.
Coping with frustration.
Balancing different areas of life.
Responding flexibly to change.
Resistance to stress
Jahoda’s criteria include the ability to cope with ordinary stress without becoming completely overwhelmed.
This does not mean that a mentally healthy person:
Never feels anxious.
Never becomes upset.
Never needs help.
Remains calm during every crisis.
It means that the person generally has enough psychological resilience to manage challenges and recover.
Coping with stress
Effective coping might involve:
Identifying the problem.
Asking for appropriate support.
Using practical strategies.
Managing emotional reactions.
Resting when needed.
Adjusting plans.
Returning to ordinary activities.
Example
During an examination period, Theo feels anxious.
He:
Creates a manageable revision plan.
Talks to a teacher.
Takes regular breaks.
Continues attending lessons.
Adjusts his plan after a poor practice result.
Theo is experiencing stress, but he is coping with it.
Example of possible deviation
Nadia experiences a small change in her timetable and becomes so overwhelmed that she cannot concentrate, sleep or complete essential tasks for several weeks.
This may indicate reduced resistance to stress.
However, a psychologist should still consider:
Whether other stressful events occurred.
How long the reaction lasts.
Nadia’s previous functioning.
Whether she receives suitable support.
Psychological conflict
Integration also concerns how the person manages internal conflict.
For example, someone might want independence while also wanting support.
Psychological health does not require removing every conflict.
It involves recognising and managing competing needs without becoming completely disorganised.
Autonomy
What is autonomy?
Autonomy means being able to act independently and regulate one’s own behaviour.
An autonomous person can:
Make personal decisions.
Develop their own values.
Resist inappropriate pressure.
Take responsibility for choices.
Work without constant approval.
Maintain independence while accepting appropriate support.
Autonomy does not mean complete isolation.
A person can be autonomous while:
Valuing relationships.
Asking for advice.
Cooperating.
Accepting help.
Following fair rules.
The key distinction is whether the person can make choices rather than being controlled entirely by other people.
Internal regulation
An autonomous person’s behaviour is guided partly by internal standards.
For example, they may refuse to join in harmful behaviour even when friends approve of it.
They do not rely completely on:
Praise.
Popularity.
Authority.
Fear of rejection.
Dependence on approval
A person may deviate from this criterion if they cannot make ordinary decisions without reassurance.
For example, they may:
Change every opinion to match the group.
Avoid making any independent choice.
Believe disagreement always leads to rejection.
Depend entirely on another person’s instructions.
Example
A friend pressures Imran to miss an important appointment.
Imran listens to the friend but decides to attend because it matches his own priorities.
This demonstrates autonomy.
Example of possible deviation
Sophie changes her clothing, interests and opinions whenever she meets a new group because she believes she has no value unless others approve of her.
This may suggest reduced autonomy because:
Her behaviour is controlled by external approval.
She appears unable to maintain independent values.
Her self-concept changes according to the group.
Autonomy and interdependence
Autonomy should not be confused with refusing all support.
Humans rely on one another.
Healthy functioning may include:
Dependable relationships.
Shared decisions.
Cooperation.
Mutual responsibility.
The ideal of complete independence may be culturally biased, particularly in communities that value family interdependence.
Accurate perception of reality
What is accurate perception?
Accurate perception of reality means interpreting:
Oneself.
Other people.
Events.
Risks.
Social situations.
in a reasonably realistic way.
The person’s conclusions should broadly reflect available evidence.
Perception of the self
Accurate self-perception involves recognising:
Genuine strengths.
Genuine limitations.
The likely effects of one’s behaviour.
The difference between feelings and facts.
For example:
“I feel that everybody dislikes me” is a feeling.
It does not automatically prove:
“Everybody dislikes me” is a fact.
Perception of other people
Accurate perception includes understanding that:
Other people have different perspectives.
Behaviour may have several explanations.
A delayed reply does not necessarily mean rejection.
One disagreement does not always end a relationship.
This supports successful social interaction.
Example
Ella’s colleague gives brief feedback on her work.
Ella considers several explanations:
The colleague may be busy.
The work may need improvement.
The feedback may not be a personal criticism.
This demonstrates relatively balanced perception.
Example of possible deviation
Marcus receives repeated reassurance that his work is satisfactory but remains convinced that every colleague is secretly planning to have him dismissed.
If this belief is strongly maintained despite clear contradictory evidence, it may indicate an inaccurate perception of reality.
Accuracy is not always easy to judge
People rarely have complete information.
Two reasonable individuals may interpret the same event differently.
Professionals should distinguish:
A plausible difference in interpretation.
A culturally shaped belief.
A temporary misunderstanding.
A serious distortion that continues despite evidence.
Empathy
Some accounts connect accurate perception with the ability to understand other people’s feelings and experiences.
A person who can recognise another perspective may be better able to:
Maintain relationships.
Resolve disagreements.
Respond sensitively.
Judge social situations accurately.
Environmental mastery
What is environmental mastery?
Environmental mastery is the ability to manage the demands of one’s environment effectively.
It may include:
Adapting to change.
Completing essential activities.
Maintaining relationships.
Solving practical problems.
Participating in work or education.
Creating suitable living conditions.
Making use of available opportunities.
The person does not control every part of the environment.
Instead, they can respond to it with reasonable effectiveness.
Adaptability
An adaptable person can modify behaviour when circumstances change.
For example, they may:
Learn a new routine.
Adjust to a different workplace.
Seek support after a setback.
Change an ineffective strategy.
Develop new relationships.
Work
Environmental mastery may involve participating in meaningful work or activity.
This could include:
Paid employment.
Education.
Voluntary work.
Caring responsibilities.
Creative projects.
It should not be reduced to having a conventional full-time job.
Love and relationships
The criterion also includes the capacity to form and maintain satisfying relationships.
This may involve:
Trust.
Communication.
Respect.
Intimacy.
Cooperation.
Appropriate boundaries.
Mutual support.
A person does not need a large friendship group or romantic relationship to meet this criterion.
People differ in their preferred level of social contact.
Example
After moving to a new town, Jay:
Learns the transport system.
Develops a new daily routine.
Maintains contact with existing friends.
Joins an activity connected to his interests.
Asks for help when needed.
This demonstrates environmental mastery.
Example of possible deviation
A relatively minor change in work routine causes Erin to stop attending, withdraw from relationships and abandon essential responsibilities for a prolonged period.
This may indicate difficulty adapting to environmental demands.
However, the judgement must consider whether:
The work environment is unsafe.
Erin has experienced discrimination.
There are financial or health barriers.
The demands are unreasonable.
How the six criteria work together
The criteria are connected.
For example:
A positive self-attitude may support autonomy.
Autonomy may make personal growth easier.
Resistance to stress may improve environmental mastery.
Accurate perception may support relationships.
Successful relationships may strengthen self-esteem.
A person does not need to meet each criterion perfectly.
Mental health can be viewed as a pattern rather than a simple yes-or-no judgement.
Example profile
Criterion | Evidence |
Positive self-attitude | The person accepts strengths and limitations |
Self-actualisation | They work towards meaningful goals |
Integration | They manage ordinary stress and emotional conflict |
Autonomy | They make independent decisions |
Accurate perception | Their conclusions broadly match available evidence |
Environmental mastery | They adapt, complete responsibilities and maintain relationships |
Absence of several criteria
A person might:
Describe themselves as worthless.
Abandon every valued goal.
Become overwhelmed by ordinary stress.
Depend entirely on reassurance.
Misinterpret neutral events as rejection.
Be unable to adapt to minor changes.
The combined pattern provides stronger evidence of deviation from ideal mental health than one isolated weakness.
AQA guidance indicates that the absence of a greater number of criteria may suggest more serious deviation.
Applying the definition to scenarios
Application method
Use five steps:
Identify a detail from the scenario.
Name the relevant Jahoda criterion.
Explain what the criterion means.
Show how the person meets or fails to meet it.
Avoid claiming that one missing criterion proves a disorder.
Scenario 1: negative self-attitude
Ravi’s friends regularly praise his abilities, but Ravi says he is completely useless and refuses to recognise anything he does well.
This may indicate deviation from positive self-attitudes because:
Ravi has a persistently negative self-view.
His judgement appears inconsistent with available evidence.
He cannot recognise his strengths.
It may also suggest inaccurate self-perception.
Scenario 2: stress
During an ordinary change of classroom, Mia becomes so overwhelmed that she cannot attend college for several weeks.
This may indicate reduced integration or resistance to stress because:
A relatively ordinary demand creates severe disruption.
Mia appears unable to regulate the emotional response.
Her coping strategies are insufficient.
The effect on attendance could also be considered through failure to function, but an answer about ideal mental health should focus on coping with stress.
Scenario 3: autonomy
Owen changes every decision to match his friends and feels unable to choose even minor activities without their permission.
This may indicate limited autonomy because:
His behaviour depends entirely on external approval.
He does not appear able to make independent choices.
Social pressure controls his behaviour.
Scenario 4: self-actualisation
Hannah has a strong interest in music and wants to develop her skills.
She practises regularly, accepts constructive feedback and sets achievable goals.
Hannah demonstrates self-actualisation because she is:
Developing her potential.
Working towards personally meaningful goals.
Learning from experience.
Scenario 5: accurate perception
Calum receives one brief message from a friend and immediately concludes that the friend hates him.
Several later messages contradict this belief, but Calum refuses to reconsider it.
This may indicate inaccurate perception because:
The conclusion is not supported by the available evidence.
Alternative explanations are ignored.
Calum maintains the belief despite contradictory information.
Scenario 6: environmental mastery
After losing a job, Amina feels disappointed but:
Updates her application materials.
Seeks financial advice.
Maintains her routine.
Talks to supportive friends.
Applies for suitable positions.
Amina is experiencing difficulty, but she demonstrates environmental mastery through effective adaptation.
Applying more than one criterion
A scenario may contain evidence relating to several criteria.
Example
Daniel says that he has no worthwhile qualities.
He has stopped pursuing activities he once valued, feels unable to cope with minor changes and asks his partner to make every decision for him.
Possible applications include:
Positive self-attitude:Â Daniel has a strongly negative view of himself.
Self-actualisation:Â He is no longer working towards valued goals.
Integration:Â Minor stress overwhelms him.
Autonomy: He depends entirely on his partner’s decisions.
A strong answer applies each criterion separately.
Avoid repeating one point
Do not write:
Daniel lacks positive self-esteem, self-acceptance and a positive view of himself.
These are three versions of the same criterion.
Instead, select genuinely different criteria and explain each one.
Meeting some criteria but not others
A person may meet one ideal criterion while missing another.
For example, they may:
Work successfully but have low self-esteem.
Be highly autonomous but struggle with relationships.
Maintain relationships but feel unable to develop their potential.
Perceive reality accurately but find stress difficult to manage.
This supports the idea of mental health as multidimensional.
A person’s psychological health cannot always be represented by one label.
Temporary deviation
People do not meet every criterion continuously.
A person may temporarily:
Lose confidence.
Struggle with stress.
Depend more heavily on family.
Pause long-term goals.
Find adapting to change difficult.
This may happen during:
Bereavement.
Illness.
Examinations.
Redundancy.
Relationship breakdown.
A move to a new area.
Financial difficulty.
Temporary deviation does not necessarily demonstrate a mental health condition.
Duration, severity and context matter.
Strengths of deviation from ideal mental health
Strength: it provides a comprehensive definition
Jahoda’s definition considers several aspects of psychological functioning.
It includes:
Thoughts about the self.
Emotional regulation.
Coping.
Independence.
Personal growth.
Relationships.
Adaptation.
This is more comprehensive than a definition based on one feature such as rarity.
Official AQA evaluation guidance identifies the comprehensive nature of the criteria as a strength.
A multidimensional view
Mental health is complex.
One person may experience difficulties in one area while functioning well in another.
Using several criteria encourages a broader assessment instead of making a judgement from one behaviour.
Strength: it focuses on positive wellbeing
The definition does not treat health simply as an absence of symptoms.
It asks whether the person is able to:
Grow.
Develop.
Cope.
Form relationships.
Make independent choices.
Engage meaningfully with life.
This provides a positive and aspirational view of mental health.
Strength: it can identify unmet needs
A person may not meet the criteria for a specific diagnosis but may still:
Have a very negative self-concept.
Lack meaningful goals.
Struggle to cope.
Experience poor relationships.
The criteria can highlight areas where support may be beneficial.
Strength: the criteria may guide treatment
The criteria can be used as goals rather than simply labels.
Support might aim to help a person:
Develop a more realistic self-view.
Improve coping skills.
Increase autonomy.
Work towards meaningful goals.
Build relationships.
Adapt more effectively.
The definition can therefore contribute to a constructive treatment plan.
Strength: it reduces dependence on social conformity
A person does not need to behave exactly like the majority to meet Jahoda’s criteria.
Someone may have:
Unusual interests.
An unconventional lifestyle.
A rare ability.
Minority cultural values.
while still demonstrating:
Autonomy.
Self-acceptance.
Growth.
Environmental mastery.
This may avoid some problems associated with defining mental health through social conformity.
Limitations of deviation from ideal mental health
Limitation: the criteria are too demanding
Jahoda describes an ideal rather than a minimum acceptable level of health.
Very few people consistently:
Maintain a positive self-view.
Develop their full potential.
Remain integrated under stress.
Act autonomously.
Perceive reality accurately.
Master every environmental demand.
Most people would fail at least one criterion.
This makes the definition overinclusive.
It may classify a very large proportion of the population as psychologically unhealthy.
Official AQA guidance identifies the demanding nature of the criteria and the risk that most people would be defined as unhealthy as a central criticism.
Ideals are not the same as minimum standards
There is a difference between:
Not achieving perfect psychological health.
Experiencing a mental health condition.
For example, a person may:
Doubt themselves occasionally.
Need advice.
Feel stressed.
Have not identified their full potential.
These experiences are common.
They do not automatically justify a mental health label.
Limitation: Western individualist bias
Some criteria reflect values particularly associated with Western individualist cultures.
These include:
Autonomy.
Individual achievement.
Personal growth.
Independent decision-making.
Self-actualisation.
Collectivist cultures may place greater value on:
Family interdependence.
Shared responsibility.
Group harmony.
Duty.
Respect for collective decisions.
A person who prioritises family goals over individual self-actualisation may be psychologically healthy within their cultural setting.
Yet a highly individualistic reading of Jahoda could classify them as lacking autonomy.
AQA evaluation guidance specifically recognises Western individualist bias as a limitation.
Culture affects the meaning of autonomy
Autonomy should not always be measured by how independently someone acts.
Healthy autonomy in one culture might involve:
Making personal choices.
In another, it might involve:
Choosing to honour shared responsibilities.
Dependence and interdependence are not identical.
Interdependence can involve mutual, valued support rather than an inability to function independently.
Limitation: the criteria are difficult to measure
Concepts such as:
Self-actualisation.
Integration.
Environmental mastery.
Accurate perception.
are abstract.
Psychologists must decide how to operationalise them.
For example:
How much independence demonstrates autonomy?
When has someone reached their potential?
How accurate must perception be?
How well must someone cope with stress?
How many relationships count as successful?
Different professionals may reach different conclusions.
This reduces reliability.
Subjective judgement
Even when a questionnaire is used, human judgement remains involved in:
Selecting the questions.
Interpreting answers.
Choosing cut-off scores.
Deciding how much deviation is significant.
The criteria appear systematic but are not completely objective.
Limitation: people have different ideals
Not everyone agrees on what a psychologically ideal life should look like.
One person may value:
Independence and achievement.
Another may value:
Family, spirituality or community.
Another may value:
Creativity, stability or service.
A universal ideal may overlook legitimate differences in goals and lifestyles.
Limitation: mental health may not resemble physical health
The definition was influenced by the idea that positive mental health could be described in the same way as positive physical health.
However, physical and psychological health may not operate identically.
Some physical functions can be measured relatively directly through:
Temperature.
Blood pressure.
Organ function.
Laboratory tests.
Psychological qualities such as fulfilment and self-acceptance are more difficult to measure.
Official AQA guidance identifies the physical-health analogy as useful but potentially inappropriate because mental health may not work in the same way.
Limitation: criteria may conflict
The ideal characteristics may pull a person in different directions.
For example:
Autonomy encourages independence.
Environmental mastery may require cooperation.
Self-actualisation may require taking risks.
Resistance to stress may sometimes require stepping back.
Positive self-attitudes may conflict with recognising serious weaknesses.
There may not always be one response that satisfies every criterion.
Example of conflicting ideals
A person is offered a demanding promotion.
Accepting it may support:
Personal growth.
Self-actualisation.
Declining it may support:
Stress management.
Family relationships.
Environmental balance.
Neither decision is automatically psychologically healthier.
Limitation: situational barriers are overlooked
A person may struggle to master their environment because the environment is extremely difficult.
Examples include:
Poverty.
Discrimination.
Unsafe housing.
War.
Disability without suitable support.
Caring responsibilities.
Lack of educational opportunity.
Classifying the person as psychologically unhealthy may place responsibility on the individual while ignoring structural barriers.
Limitation: it may pathologise understandable reactions
After a major loss, a person may temporarily:
Lose a positive self-view.
Stop pursuing goals.
Depend heavily on others.
Struggle to manage the environment.
Find stress overwhelming.
These reactions may be understandable.
Applying an ideal standard too rigidly could turn normal human responses into signs of illness.
Limitation: outward fulfilment may hide distress
A person might appear to:
Work towards goals.
Maintain relationships.
Act independently.
Adapt successfully.
while experiencing severe private distress.
Meeting visible criteria does not guarantee good mental health.
This is similar to the problem that outward functioning may conceal psychological difficulty.
Limitation: it does not explain causes
Deviation from ideal mental health identifies areas of possible difficulty.
It does not explain:
Why the problem developed.
Which factors maintain it.
Which treatment will work.
Whether biological, cognitive or environmental factors are responsible.
It is a definition, not an explanation of psychological disorders.
False positives and false negatives
False positive
A false positive occurs when a psychologically healthy person is incorrectly identified as having a difficulty.
This could happen because the person:
Does not meet every demanding criterion.
Values interdependence rather than autonomy.
Is temporarily stressed.
Chooses not to pursue conventional achievements.
Has limited opportunities for personal growth.
False negative
A false negative occurs when a person with a genuine difficulty is not identified.
This could happen if the person:
Appears successful.
Maintains independence.
Hides distress.
Continues working towards goals.
Gives socially desirable answers on an assessment.
The criteria should therefore be combined with other information.
Reliability and validity
Reliability
The definition may have limited reliability because professionals may interpret the criteria differently.
Reliability could be improved through:
Clearly defined assessment questions.
Standardised interviews.
Trained assessors.
Several sources of evidence.
Repeated assessments.
Agreed scoring criteria.
However, concepts such as fulfilment cannot be made completely objective.
Validity
The definition has some validity because it captures important features of wellbeing.
It recognises that psychological health involves more than:
Being statistically typical.
Following social rules.
Completing basic tasks.
Validity is reduced when:
Cultural values are ignored.
Normal imperfection is classified as illness.
Situational barriers are treated as personal failure.
Abstract criteria are measured poorly.
Comparing the four definitions
Definition | Central question | Main strength | Main limitation |
Statistical infrequency | Is the behaviour rare? | Uses numerical population data | Rare characteristics may be desirable |
Deviation from norms | Does behaviour violate expectations? | Considers social context | Norms vary across cultures and situations |
Failure to function adequately | Can the person cope with everyday life? | Considers distress and practical effects | Adequate functioning is subjective |
Deviation from ideal mental health | Does the person possess positive qualities of wellbeing? | Comprehensive and positive | The ideal is demanding and culturally influenced |
Ideal mental health compared with statistical infrequency
A person may possess an extremely rare ability.
Statistical infrequency identifies the ability as unusual.
Ideal mental health asks whether the person has a positive self-view, develops their potential and manages life effectively.
The ideal definition is less likely to treat unusual strengths as psychological problems.
Ideal mental health compared with social norms
A person may reject a local social expectation.
Deviation from norms identifies nonconformity.
Ideal mental health may view the decision as evidence of autonomy.
This shows that conformity and positive mental health are not identical.
Ideal mental health compared with failure to function
A person may successfully complete ordinary responsibilities but:
Have a strongly negative self-view.
Lack meaningful goals.
Depend completely on approval.
Failure to function may not identify a problem.
Deviation from ideal mental health may identify reduced wellbeing.
Alternatively, a person may fail to complete tasks temporarily because of bereavement but still possess a stable identity, supportive relationships and long-term autonomy.
The definitions can therefore produce different conclusions.
Applying all four definitions
Example: rare talent
A person has an exceptional musical ability.
Statistical infrequency:Â The ability is rare.
Deviation from norms:Â It is socially valued.
Failure to function:Â It does not interfere with everyday life.
Ideal mental health:Â Developing the talent may demonstrate self-actualisation.
Conclusion: rarity does not indicate poor mental health.
Example: intense fear
A person experiences a severe fear that prevents travel.
Statistical infrequency considers whether the response is rare.
Social norms consider whether the response is appropriate to the situation.
Failure to function considers the impact on everyday life.
Ideal mental health considers coping, autonomy and environmental mastery.
This example may connect with the features of phobias.
Example: persistent low mood
A person experiences persistent low mood, self-criticism and loss of motivation.
The condition may not be statistically rare.
The person may still conform socially.
Everyday functioning may deteriorate.
Positive self-attitudes and self-actualisation may be reduced.
The different definitions reveal different parts of the behavioural, emotional and cognitive features of depression.
Example: repetitive rituals
A person spends several hours completing rituals and feels unable to resist them.
The behaviour may be statistically unusual.
It may violate expectations about ordinary routines.
It may interfere with work and relationships.
It may reduce autonomy and environmental mastery.
The distinction between obsessions and compulsions provides further context.
Answering application questions
Application structure
Use the following sentence pattern:
The scenario suggests a lack of [criterion]Â because [specific evidence]. This criterion involves [brief explanation], so the behaviour may represent deviation from ideal mental health.
Example
Noor may lack autonomy because she asks her friends to make every decision and changes her opinion whenever they disagree. Autonomy involves independent self-regulation, so her complete dependence on external approval may represent deviation from ideal mental health.
Use the evidence precisely
Weak application:
Noah has poor mental health because he is stressed.
Stronger application:
Noah’s anxiety prevents him coping with relatively ordinary demands, which may indicate reduced integration or resistance to stress. This is one of Jahoda’s criteria for ideal mental health.
Distinguish the definitions
Suppose a person cannot attend work.
For failure to function, write:
The inability to attend work shows that the person cannot manage an ordinary responsibility.
For ideal mental health, write:
The person may lack environmental mastery because they cannot adapt to or manage demands within their environment.
Both may be relevant, but the psychological explanation differs.
Avoid diagnosing from one criterion
Do not conclude:
“The person lacks autonomy, so they have a mental disorder.”
A more accurate conclusion is:
“The person’s dependence may indicate deviation from one criterion, but broader assessment would be required.”
Evaluating the ideal standard effectively
Comprehensive-criteria paragraph
A strength is that Jahoda provides a comprehensive account of mental health. The criteria include self-attitudes, growth, coping, independence, perception and environmental adaptation. This recognises that psychological wellbeing has several dimensions rather than being defined only by the absence of symptoms.
Demanding-criteria paragraph
A limitation is that the standard is unrealistically demanding. Most people sometimes experience low confidence, depend on others or struggle with stress. If missing any criterion indicates poor mental health, almost everyone could be classified as unhealthy. The definition may therefore confuse ordinary imperfection with psychological disorder.
Cultural-bias paragraph
The emphasis on autonomy and self-actualisation reflects individualist values. Collectivist cultures may place greater importance on family interdependence and group goals. A person who chooses shared decision-making may therefore be psychologically healthy within their culture but appear insufficiently autonomous according to the ideal.
Physical-health comparison paragraph
The definition attempts to describe positive mental health in the same way that positive physical health can be described. However, qualities such as fulfilment and accurate perception are more subjective than many physical measurements. The analogy may therefore make mental health appear more objectively measurable than it is.
Practical-value paragraph
The criteria can be used constructively to identify areas for support. For example, treatment might aim to improve self-acceptance, coping or autonomy rather than merely remove symptoms. However, the criteria are more appropriate as therapeutic goals than as a rigid diagnostic boundary.
A balanced conclusion
Deviation from ideal mental health offers a valuable positive and comprehensive account of psychological wellbeing.
It recognises the importance of:
Self-acceptance.
Growth.
Coping.
Independence.
Realistic thinking.
Relationships.
Adaptability.
However, the definition should not be used as a strict checklist.
The ideal is:
Difficult to achieve.
Difficult to measure.
Influenced by cultural values.
Sensitive to temporary circumstances.
More aspirational than diagnostic.
The most justified conclusion is:
Jahoda’s criteria are useful for describing areas of positive psychological wellbeing and setting goals for support, but failing to meet an ideal should not automatically be treated as evidence of mental illness.
Hints from the Examiner Reports đź’ˇ
Examiner hint:Â Begin with the central definition. Psychological difficulty is identified through the absence of criteria associated with positive or optimal mental health.
Examiner hint:Â Learn specific criteria. Useful terms include positive self-attitudes, self-actualisation, resistance to stress, autonomy, accurate perception of reality and environmental mastery.
Examiner hint:Â Do not blend this definition with failure to function adequately. Missing work is evidence of everyday impairment, but it should be linked to environmental mastery or self-actualisation when the question asks about ideal mental health.
Examiner hint: Application must identify a criterion and connect it to precise evidence. Writing that someone “does not have ideal mental health” simply repeats the question.
Examiner hint:Â A person does not need to lack every criterion. Different pieces of a scenario may demonstrate different areas of deviation.
Examiner hint: Positive self-attitude concerns the person’s view of themselves. Accurate perception concerns whether this view and their understanding of events are reasonably consistent with evidence.
Examiner hint:Â Keep evaluation specific to the ideal definition. Relevant points include its comprehensive nature, the physical-health analogy, demanding standards and Western individualist bias.
Examiner hint:Â Do not describe the criteria as a formal diagnosis. They provide standards of psychological wellbeing rather than a diagnostic test for a particular disorder.
The June 2023 examiner report noted that answers lost marks when students allowed the four definitions to overlap. Stronger application identified specific criteria, particularly resistance to stress, positive self-attitudes and accurate perception of reality.
The associated mark scheme also credited application to concentration and potential, inaccurate self-perception, difficulty coping with anxiety and a negative view of the self.
Common Mistakes ⚠️

D. Complete absence of negative emotion
[1 mark]
reveal mark scheme and indicative content
Answer: B. Environmental mastery
Question 2
Define deviation from ideal mental health.
[2 marks]
reveal mark scheme and indicative content
Mark scheme
AO1 = 2
2 marks:Â Clear definition referring to failure to meet one or more criteria for positive or ideal psychological wellbeing.
1 mark:Â Limited or partial definition.
Indicative content
Jahoda proposed criteria representing optimal mental health.
A person may be considered to deviate from ideal mental health when these criteria are absent.
The more criteria a person fails to meet, the greater the deviation from ideal mental health.
AQA states that the essential feature of this definition is the absence of criteria for good mental health
Question 3
Outline two of Jahoda’s criteria for ideal mental health.
[4 marks]
reveal mark scheme and indicative content
Mark scheme
AO1 = 4
Award up to 2 marks for each clearly outlined criterion.
Indicative content
Credit any two:
Positive attitude towards the self, having self-esteem and accepting oneself.
Self-actualisation, developing and working towards one's potential.
Integration/resistance to stress, being able to cope with stressful situations and maintain psychological balance.
Autonomy, being independent and able to make one's own decisions.
Accurate perception of reality, seeing oneself and the world realistically.
Environmental mastery, being able to cope with and adapt to the demands of everyday life.
Example answer
One criterion is autonomy, meaning that a psychologically healthy person can make independent decisions without excessive dependence on others. Another is environmental mastery, meaning that the person can cope with and adapt successfully to the demands of their environment.
Question 4
Explain one difference between autonomy and environmental mastery.
[3 marks]
reveal mark scheme and indicative content
Mark scheme
AO1 = 3
1 mark:Â Autonomy concerns independence and self-direction.
1 mark:Â Environmental mastery concerns coping with and adapting to the external environment.
1 mark:Â Clear comparison or elaboration.
Example answer
Autonomy refers to being independent and able to make one's own decisions without excessive reliance on others. Environmental mastery refers to being able to cope with and adapt to the demands of one's surroundings. Therefore, autonomy concerns independence, whereas environmental mastery concerns effective adjustment to the environment.
Question 5
Niamh changes every decision to match her friends and says that she cannot choose what to do unless they approve.
Use deviation from ideal mental health to explain Niamh’s behaviour.
[4 marks]
reveal mark scheme and indicative content
Mark scheme
AO2 = 4
Award 1 mark each for:
Identifying autonomy as a relevant Jahoda criterion.
Autonomy involves being independent and making one's own decisions.
Niamh changes her decisions to match her friends.
Her need for their approval and inability to choose independently suggest deviation from ideal mental health on this criterion.
Example answer
Niamh may deviate from ideal mental health because she does not show autonomy. Jahoda argued that good mental health involves being independent and able to make one's own decisions. Niamh instead changes her decisions to match her friends and says she cannot choose without their approval, showing excessive dependence on others.
Question 6
Aaron describes himself as worthless despite receiving consistently positive feedback. He has stopped working towards activities that he previously valued.
Use two of Jahoda’s criteria to explain how Aaron may deviate from ideal mental health.
[6 marks]
reveal mark scheme and indicative content
Mark scheme
AO2 = 6
Award up to 3 marks for each appropriately applied criterion.
Indicative content
Positive attitude towards the self
Aaron describes himself as worthless.
This suggests low self-esteem or poor self-acceptance.
He therefore fails to meet Jahoda's criterion of having a positive attitude towards oneself.
Self-actualisation
Aaron has stopped pursuing activities he previously valued.
Self-actualisation involves working towards one's potential and personal development.
His withdrawal from these goals suggests he is no longer working towards self-actualisation.
Also credit accurate perception of reality if clearly linked to his negative self-judgement despite consistently positive feedback.
Example answer
Aaron may fail to meet Jahoda's criterion of a positive attitude towards the self because he describes himself as worthless despite receiving positive feedback. This suggests poor self-esteem and self-acceptance. He may also fail to meet the criterion of self-actualisation because he has stopped working towards activities that he previously valued. He is therefore no longer actively developing towards his potential.
Question 7
Following a change to her college timetable, Cara becomes extremely anxious and is unable to adjust her routine.
Explain Cara’s behaviour using integration and environmental mastery.
[4 marks]
reveal mark scheme and indicative content
Mark scheme
AO2 = 4
Award up to 2 marks for integration and 2 marks for environmental mastery.
Indicative content
Integration
Integration includes being able to cope with stress and maintain psychological stability.
Cara becomes extremely anxious in response to the timetable change, suggesting difficulty coping with stress.
Environmental mastery
This involves adapting effectively to changing circumstances.
Cara is unable to adjust her routine following the timetable change.
Example answer
Cara may deviate from ideal mental health in terms of integration because she becomes extremely anxious when faced with the timetable change, suggesting difficulty coping with stress. She also shows poor environmental mastery because she is unable to adapt her routine to the new demands of her environment.
AQA explicitly credits both resistance to stress and the ability to adapt as features of ideal mental health.
Question 8
A psychologist asks participants to rate themselves from 1 to 10 on each of Jahoda’s criteria.
Explain one problem with using these ratings to measure ideal mental health.
[4 marks]
reveal mark scheme and indicative content
Mark scheme
AO3 = 4
Award credit for one clearly developed methodological problem.
Indicative content
For example:
The ratings are self-report data and therefore subjective.
Participants may interpret criteria such as self-actualisation or environmental mastery differently.
Participants may also give socially desirable answers because they want to appear psychologically healthy.
Consequently, scores may not accurately reflect the person's actual mental health, reducing validity.
Example answer
One problem is that the ratings are subjective self-reports. Different participants may interpret concepts such as autonomy or environmental mastery differently. They may also exaggerate positive qualities because they want to appear mentally healthy. This means the ratings may not accurately measure whether Jahoda's criteria are genuinely being met.
Question 9
Explain one strength and one limitation of deviation from ideal mental health as a definition in the field of mental health.
[6 marks]
reveal mark scheme and indicative content
Mark scheme
AO3 = 6
Award up to 3 marks for the strength and 3 marks for the limitation.
Indicative content
Strength
It provides a positive and comprehensive view of mental health.
Rather than focusing only on symptoms or unusual behaviour, it considers qualities associated with psychological wellbeing.
The criteria can therefore identify areas in which a person's wellbeing could potentially be improved.
Limitation
Jahoda's criteria are extremely demanding.
Very few people are likely to meet all of them all of the time.
As a result, the definition risks identifying most people as deviating from ideal mental health.
Also credit cultural bias as a limitation. AQA specifically recognises that the criteria may be too demanding and that several reflect Western cultural ideals.
Example answer
One strength is that deviation from ideal mental health takes a positive approach. It considers what good psychological health should look like, such as autonomy and self-actualisation, rather than defining mental health only through problems or symptoms.
One limitation is that Jahoda's criteria may be unrealistically demanding. Few people are autonomous, resistant to stress, self-actualising and psychologically well adjusted at all times. Therefore, the definition could classify a very large proportion of healthy people as deviating from ideal mental health.
Question 10
Discuss deviation from ideal mental health as a definition in the field of mental health.
[8 marks]
reveal mark scheme and indicative content
Discuss deviation from ideal mental health as a definition in the field of mental health. [8 marks]
Mark scheme
Suggested allocation: AO1 = 3, AO3 = 5
7 to 8 marks:Â Knowledge of deviation from ideal mental health is accurate and detailed. Discussion is thorough and effective, with clear consideration of strengths and limitations.
5 to 6 marks:Â Knowledge is generally accurate and discussion is mostly effective, although some points lack development.
3 to 4 marks:Â Some relevant knowledge is present, but discussion is limited or mainly descriptive.
1 to 2 marks:Â Very limited knowledge or discussion.
0 marks:Â No relevant content.
Indicative content
AO1
Jahoda proposed that ideal mental health involves criteria such as:
positive attitude towards the self
self-actualisation
integration or resistance to stress
autonomy
accurate perception of reality
environmental mastery.
A person who fails to meet these criteria can be seen as deviating from ideal mental health. AQA notes that the more criteria that are absent, the greater the deviation from optimal mental health.
AO3
Positive approach:Â defines mental health in terms of desirable psychological qualities rather than simply the absence of symptoms.
Comprehensive:Â considers several aspects of wellbeing rather than relying on one behaviour or characteristic.
Unrealistically demanding:Â very few people are likely to satisfy every criterion all of the time, potentially classifying most people as psychologically unhealthy.
Cultural bias:Â autonomy and self-actualisation particularly reflect individualistic Western values. Collectivist cultures may place greater value on dependence and group goals.
Measurement difficulties:Â concepts such as self-actualisation and accurate perception of reality can be difficult to operationalise objectively.
No clear threshold:Â it can be unclear how many criteria must be absent before someone's mental health should be considered problematic.
The definition may therefore be useful as an ideal for wellbeing, but less useful as a stand-alone method of identifying mental health difficulties.
AQA's published evaluation guidance particularly emphasises the demanding nature of the criteria and their reflection of Western cultural norms. Â Examiner feedback also notes that stronger answers develop specific criticisms of Jahoda's individual criteria rather than making generic evaluation points.
Example answer
Deviation from ideal mental health defines psychological difficulty as failing to meet criteria for optimal wellbeing. Jahoda proposed criteria including a positive attitude towards the self, self-actualisation, autonomy, resistance to stress, accurate perception of reality and environmental mastery. The more of these criteria a person fails to meet, the further they may be considered to deviate from ideal mental health.
One strength is that the definition takes a positive and comprehensive view of mental health. It identifies qualities associated with healthy functioning rather than focusing only on symptoms. However, the criteria are very demanding because few people will meet all of them all of the time. For example, most psychologically healthy people sometimes struggle with stress. The definition may also be culturally biased because criteria such as autonomy and self-actualisation reflect individualistic Western values and may be less appropriate in cultures that value interdependence. Some criteria are also difficult to measure objectively. Therefore, Jahoda's criteria provide a useful description of ideal wellbeing, but they are less suitable as a rigid definition of mental health difficulty.
