A-Level Psychology: Schizophrenia

Schizophrenia is one of the most widely taught option topics in A-level Psychology, and questions on it expect you to move quickly between recognising symptoms, weighing explanations against evidence and judging how well treatments work. This material covers the topic as it now stands in the revised specifications (for example, AQA's A-level Psychology for first teaching from September 2025), where the focus in diagnosis has shifted from classification systems to issues in diagnosis.

The quiz opens with short patient scenarios. You decide whether described experiences are positive symptoms (hallucinations, delusions) or negative ones (avolition, speech poverty), and which issue in diagnosis a case illustrates: co-morbidity, culture bias or gender bias, with Loring and Powell's case-description study as evidence.

The explanation questions ask you to interpret evidence rather than recall labels. You draw conclusions from Gottesman's twin concordance figures, separate the original from the revised dopamine hypothesis, and spot the causal limitation of neural-correlate findings such as reduced ventral striatum activity. On the psychological side you apply Frith's idea of faulty metarepresentation to hearing voices and thought insertion, and recognise the double bind in a family scenario.

Treatment questions compare typical antipsychotics such as chlorpromazine with atypical drugs such as clozapine and risperidone, including their mechanisms and side effects, and set out what cognitive behaviour therapy (reality testing, normalisation) and family therapy (reducing expressed emotion, psychoeducation) actually do. The final question uses the pattern found in the Finnish adoption study to show why the diathesis-stress model, and the interactionist approach behind it, fits the evidence better than any single explanation.

The material offers four formats. The 12-question quiz gives an explanation after every answer. The flashcard deck covers the key terms and studies, including symptom overlap and the schizophrenogenic mother. The printable written work sets eight open questions, from short outlines to extended evaluation, with ruled space for handwritten answers that are then checked. The oral exam puts you in front of an examiner who asks one question at a time, follows up on your reasoning and gives feedback at the end.

Use it after first teaching of the topic, or in the run-up to the Paper 3 options, to check that you can apply each explanation and treatment to a case and evaluate it with named evidence.

• Classify described experiences as positive symptoms (hallucinations, delusions) or negative symptoms (avolition, speech poverty)
• Explain co-morbidity, culture bias, gender bias and symptom overlap as issues in the diagnosis of schizophrenia
• Interpret twin concordance evidence and explain the original and revised dopamine hypotheses and neural correlates
• Apply family dysfunction and Frith's cognitive explanation to case descriptions
• Compare typical and atypical antipsychotics, CBT and family therapy, including their limitations
• Use the diathesis-stress model to explain why an interactionist approach fits the evidence
