AQA A-Level Psychology Paper 1 Clinical Psychology and Mental Health essays
Clinical Psychology and Mental Health is a compulsory topic in AQA A-Level Psychology Paper
1: Introductory Topics in Psychology. The updated specification includes the behavioural explanation and treatment of phobias, the cognitive explanation and treatment of depression, and biological explanations and treatments for OCD. Specifically, students need the two-process model, systematic desensitisation, flooding, Beck and Ellis, CBT, genetic and neural explanations of OCD, and drug therapy.
For "discuss" questions, accurate description is only the starting point. Students should use research evidence, alternative explanations and questions of effectiveness or appropriateness to develop a focused evaluation.
Discuss the two-process model of phobias.
How to answer this question
The phrase two-process is crucial. Your essay must explain both:
acquisition through classical conditioning
maintenance through operant conditioning
A common mistake is to describe classical conditioning in lots of detail and barely mention operant conditioning. Keep the two processes clearly separated and explain exactly how each contributes to a phobia.
For evaluation, focus on whether conditioning can account for the development and persistence of all phobias.
Indicative points
You could include:
The two-process model proposes that phobias are acquired through classical conditioning and maintained through operant conditioning.
Before conditioning, the future phobic object may be a neutral stimulus.
If it becomes associated with a frightening or painful event, it can become a conditioned stimulus.
The formerly neutral object can then produce fear as a conditioned response.
Fear may generalise from the original stimulus to similar objects or situations.
The phobia is then maintained through operant conditioning.
Avoiding the feared object reduces anxiety.
This relief acts as negative reinforcement, making avoidance more likely to occur again.
This distinction is central to previous marking guidance, which treats classical conditioning as the acquisition process and negatively reinforced avoidance as the maintenance process.
For discussion, consider:
Watson and Rayner's research as evidence that fear can be learned through association
research showing associations between traumatic experiences and later phobias
many people experience traumatic events without developing a phobia
some people cannot identify a traumatic event that caused their phobia
an evolutionary explanation such as preparedness may explain why some fears are much easier to acquire than others
the model may underplay cognitive factors involved in phobias
the success of behavioural treatments provides some support for the learning principles behind the explanation
The 2020 examiner report noted that stronger answers made the distinction between classical and operant conditioning very clear. Weaker answers sometimes mentioned studies or systematic desensitisation without explaining their relevance to the two-process model itself.
Discuss systematic desensitisation as a behavioural treatment for phobias.
How to answer this question
There are two things to do:
explain how systematic desensitisation works
evaluate its appropriateness and effectiveness
Make sure you include the two elements specifically named in the current specification, relaxation and the use of an anxiety hierarchy.
A strong answer does not simply list the stages. Explain why gradual exposure should reduce the phobic response.
Indicative points
You could include:
Systematic desensitisation is a behavioural treatment based on learning principles.
The client is taught relaxation techniques.
Therapist and client construct an anxiety hierarchy.
The hierarchy contains situations involving the phobic stimulus, arranged from least to most anxiety-provoking.
The client gradually works through the hierarchy.
Exposure to each stage is combined with relaxation.
The person moves to increasingly challenging situations as anxiety decreases.
The aim is for the feared stimulus to stop producing the previous intense anxiety response.
Exposure may initially be imagined before progressing to more direct exposure, depending on the treatment.
For discussion, you could consider:
systematic desensitisation avoids the intense immediate exposure associated with flooding
gradual treatment may therefore be more acceptable to some clients
completion of treatment may be more likely if the person finds the procedure manageable
the treatment can take considerable time because relaxation must be learned and exposure is gradual
improvement in the treatment setting may not always generalise to situations outside therapy
it may be more difficult to construct a clear hierarchy for broad or generalised phobias
evidence of effectiveness can be compared with alternative behavioural or psychological treatments
The June 2022 mark scheme specifically identified time demands, problems generalising progress outside therapy and difficulties using a hierarchy for some broader phobias as possible limitations.
Discuss flooding as a behavioural treatment for phobias.
How to answer this question
Flooding is also an exposure treatment, but do not describe it as though it is simply a faster version of systematic desensitisation.
The key distinction is that flooding does not gradually work through an anxiety hierarchy. Instead, the client confronts a highly feared situation directly.
Your evaluation should therefore consider both effectiveness and whether this type of treatment is appropriate for the individual.
Indicative points
You could include:
Flooding is a behavioural treatment based on direct exposure to the phobic stimulus.
The person is exposed to a highly anxiety-provoking version of the feared situation rather than progressing gradually through a hierarchy.
Avoidance of the feared stimulus is prevented during treatment.
Exposure continues long enough for the fear response to reduce.
The client learns that the feared object or situation does not produce the catastrophic outcome they expect.
This weakens the learned association between the stimulus and fear.
Because avoidance is prevented, the negative reinforcement that normally maintains the phobia is also disrupted.
For discussion, consider:
flooding may work much more quickly than gradual systematic desensitisation
fewer therapy sessions may make it less costly
intense exposure can be extremely stressful
some clients may refuse the treatment or withdraw before it is completed
incomplete treatment could leave the person with continuing fear
it therefore requires informed consent and careful consideration of the client's suitability
systematic desensitisation may be preferred by people who cannot tolerate immediate intense exposure
both treatments are based on behavioural principles, so their effectiveness can also provide indirect support for learning explanations of phobias
The lesson sequence explicitly encourages comparison of flooding with systematic desensitisation and evaluation in terms of appropriateness and effectiveness.
Discuss Ellis’s cognitive explanation of depression.
How to answer this question
Build your AO1 around Ellis's ABC model.
Do not merely state what A, B and C stand for. Explain the important claim that the emotional consequence is produced by the person's belief about the event, rather than automatically by the event itself.
Then evaluate whether irrational thinking provides a sufficient explanation for depression.
Indicative points
You could include:
Ellis argued that depression can result from irrational beliefs.
A is the activating event, such as experiencing criticism or another negative life event.
B is the belief the individual holds about that event.
Irrational beliefs can include unrealistic demands and negative interpretations.
C is the consequence of those beliefs, which can include depression and anxiety.
Therefore, the same activating event does not necessarily produce the same emotional consequence in everyone.
It is the individual's interpretation or belief that is important.
Relevant forms of irrational thinking include musterbation, catastrophising and utopianism. These are all accepted within recent marking guidance for Ellis's model.
For discussion, consider:
cognitive vulnerabilities have been found to precede depression in some research
CBT is based on changing maladaptive thinking, providing a useful practical application of the explanation
if changing irrational thoughts reduces depressive symptoms, this is consistent with the cognitive approach
however, the success of treatment does not automatically prove that irrational beliefs originally caused the disorder
negative thinking could sometimes be a consequence rather than a cause of depression
Ellis's model may be particularly useful for understanding reactive depression following negative events
biological and social explanations suggest depression is unlikely to have one single cause
difficult social circumstances, such as severe poverty or loss, should not simply be reduced to irrational thinking
The 2023 examiner report found that stronger responses explained all three parts of the ABC model and used evaluation such as CBT, problems explaining endogenous depression and comparison with alternative explanations.
Discuss cognitive behaviour therapy as a treatment for depression.
How to answer this question
The current specification specifically requires CBT including challenging irrational thoughts, so make that the centre of your explanation.
Explain what the therapist and client actually do. Then evaluate whether CBT is effective and appropriate for different people with depression.
Indicative points
You could include:
CBT is based on the idea that maladaptive patterns of thinking contribute to depression.
Therapy aims to identify and challenge negative or irrational thoughts.
The client may learn to recognise automatic negative thoughts through thought catching.
The therapist can encourage the client to examine evidence for and against these beliefs.
The client may act as a scientist, testing whether negative predictions are actually supported.
Homework tasks and diaries can be used to gather evidence outside therapy sessions.
Negative beliefs can then be replaced with more realistic interpretations through cognitive restructuring.
Ellis's approach can involve direct rational confrontation of irrational beliefs.
The aim is to alter thinking patterns and, as a result, reduce depressive symptoms.
These techniques are reflected in specimen marking guidance, which includes thought catching, hypothesis testing, data gathering, homework, cognitive restructuring and rational confrontation.
For discussion, consider:
CBT has a clear theoretical basis in cognitive explanations of depression
evidence that CBT reduces symptoms provides support for its practical usefulness
it gives clients strategies that may continue to be used after formal treatment ends
the client takes an active role rather than simply receiving a treatment
however, this also requires motivation and engagement
severely depressed clients may initially find the demands of therapy difficult
CBT requires trained therapists and repeated sessions
biological treatments may sometimes be useful alongside psychological treatment
symptom improvement following CBT does not necessarily prove that irrational thinking was the original cause of depression
depression is heterogeneous, so no treatment is equally suitable for everyone
A useful distinction from past marking guidance is that simply naming the ABCDE model is not enough. Students need to explain how thoughts are challenged and how this should reduce depression.
Discuss genetic explanations of obsessive-compulsive disorder (OCD).
How to answer this question
Avoid writing that there is simply an "OCD gene".
Genetic explanations propose an inherited vulnerability involving many genes. Make the concepts of polygenic inheritance and genetic vulnerability central to the essay.
Then ask whether the genetic evidence shows that genes cause OCD or merely increase risk.
Indicative points
You could include:
Genetic explanations propose that a vulnerability to OCD can be inherited across generations.
OCD appears to be polygenic, meaning many genes contribute to vulnerability.
Previous marking guidance has accepted research suggesting that potentially very large numbers of candidate genes are involved.
Specific candidate genes have been associated with neurotransmitter systems relevant to OCD.
Different combinations of genes may contribute to OCD in different individuals.
This is known as aetiological heterogeneity.
Different combinations may also help account for the variety of OCD symptoms seen between individuals.
Therefore, genetic inheritance is better understood as increasing risk or predisposition than guaranteeing that OCD will develop.
For discussion, consider:
twin and family research supports a genetic contribution
previous marking guidance cites higher concordance in monozygotic than dizygotic twins as supporting evidence
concordance is not 100%, which demonstrates that genes cannot provide a complete explanation
relatives also share environments, so family similarities are not automatically genetic
environmental events, including trauma, may contribute to the onset of OCD
a diathesis-stress explanation can combine genetic vulnerability with environmental triggers
genetic explanations may be biologically reductionist if psychological and environmental influences are ignored
there are problems establishing cause and effect from associations between particular genes and OCD
The 2022 mark scheme explicitly allows discussion of shared environments, trauma, biological reductionism and the diathesis-stress model alongside genetic evidence.
Discuss neural explanations of obsessive-compulsive disorder (OCD).
How to answer this question
"Neural explanations" covers more than serotonin.
A strong essay should address both:
neurochemical explanations
abnormal functioning in brain structures or circuits
The current lesson plan specifically requires both brain structures and neurochemistry.
Then evaluate whether these neural differences cause OCD or simply correlate with it.
Indicative points
You could include:
Neural explanations link OCD to differences in neurotransmitter functioning.
Serotonin is particularly important in biological explanations of OCD.
Abnormal serotonin transmission may be associated with obsessive thoughts and mood regulation.
Other neurotransmitters, including dopamine, may also be involved.
Neural explanations also consider abnormal functioning in particular brain areas and circuits.
Recent marking guidance identifies the parahippocampal gyrus, basal ganglia and orbitofrontal cortex as relevant.
Hyperactivity in the basal ganglia may be linked with repetitive compulsive actions.
The orbitofrontal cortex forms part of a circuit involved in processing worries.
Dysfunction involving the caudate nucleus-thalamus loop may result in difficulty filtering minor worries, creating an overactive "worry circuit".
For discussion, consider:
brain-imaging and neurochemical evidence provides objective biological evidence of differences associated with OCD
drug treatments that alter serotonin can reduce symptoms in some people
however, the existence of an effective drug does not necessarily establish the original cause of a disorder
this is sometimes described as the treatment fallacy
not everyone with OCD shows the same neural abnormalities
some findings concerning abnormal brain functioning have proved difficult to replicate
it is difficult to establish whether neural abnormalities cause OCD or develop as a consequence of the disorder
genetic influences could partly explain neural differences
environmental and psychological factors may also contribute
therefore, neural explanations alone may be biologically reductionist
The June 2025 mark scheme is particularly useful here. It warns that multiple neural factors have been identified but are not present in every case, and it accepts discussion of treatment fallacy and difficulties establishing a simple causal explanation.
Discuss drug therapy as a biological treatment for obsessive-compulsive disorder (OCD).
How to answer this question
Keep the essay about treating OCD, rather than drifting into a general description of biological explanations.
You should explain how SSRIs affect serotonin transmission and include at least one alternative drug treatment.
Then evaluate drug therapy in terms of effectiveness, side effects and appropriateness.
Indicative points
You could include:
Drug therapy aims to alter neurotransmitter activity associated with OCD.
Selective serotonin reuptake inhibitors (SSRIs) are commonly used.
SSRIs reduce the reabsorption or reuptake of serotonin after it has been released into the synapse.
This means serotonin remains available to continue stimulating the postsynaptic neuron.
The aim is to increase effective serotonin transmission and reduce OCD symptoms.
Fluoxetine is an example of an SSRI.
SSRIs do not normally produce an immediate change in symptoms.
The June 2025 mark scheme accepts a treatment period of several months for the effects of SSRIs to become established.
Alternative drugs can include tricyclics or SNRIs, with other drug types also sometimes considered.
For discussion, consider:
SSRIs can reduce symptoms for many people with OCD
however, not all patients respond to drug treatment
this individual variation also raises questions about simple serotonin explanations of OCD
there can be side effects, which may reduce adherence
drug treatment is relatively cheap and easy to administer compared with therapies requiring large amounts of professional time
taking medication is comparatively undemanding for the patient
this can also be viewed as a limitation because it is a passive treatment
medication may reduce symptoms without giving the person insight into their thoughts and behaviour
symptoms may return if treatment is discontinued
psychological treatments can therefore be considered as alternatives or used alongside medication
the delayed effects of drug treatments suggest that their action may be more complicated than simply increasing serotonin
the treatment fallacy means that successful treatment with serotonin-related medication does not prove that low serotonin originally caused OCD
Recent marking guidance explicitly accepts side effects, individual differences in response, delayed effects, low cost, ease of administration and the passive nature of drug treatment as useful discussion points.
A recurring examiner warning is also worth remembering. In the 2021 paper, some students wrote about biological explanations of OCD rather than biological treatment, even though the question asked about drug therapy. The strongest answers described the synaptic action of SSRIs accurately and stayed focused on treatment.
Final tips for AQA A-Level Psychology Clinical Psychology essays
Across these essays, a few habits will make answers much more focused:
Separate explanation from treatment. The two-process model explains phobias, while systematic desensitisation and flooding treat them. Ellis explains depression, while CBT treats it. Genetic and neural accounts explain OCD, while drug therapy treats it.
Know the mechanisms. Do not simply say SSRIs "increase serotonin" or that avoidance "reinforces fear". Explain what actually happens.
Use the precise terminology. Classical conditioning, negative reinforcement, anxiety hierarchy, irrational beliefs, genetic vulnerability, polygenic inheritance, serotonin and reuptake should all be used accurately.
Make evaluation specific. A generic criticism of a study earns much less than explaining what that criticism means for the explanation or treatment.
Evaluate treatments using appropriateness as well as effectiveness. Think about side effects, distress, time, cost, individual differences and whether the treatment addresses the underlying problem.
Avoid single-cause explanations. Phobias, depression and OCD are complex disorders, so comparing behavioural, cognitive, biological and environmental explanations can produce strong AO3.
Be careful with cause and effect. Finding a neural or genetic difference associated with a disorder does not automatically demonstrate that it caused the disorder.
Link research back to the essay title. A named study is only useful if you explain whether its findings support or challenge the point you are making.
