Active learning ideas
The classification and diagnosis of schizophrenia is one of the most debated areas in clinical psychology. Students learn to distinguish between positive symptoms, like hallucinations and delusions, and negative symptoms, such as speech poverty and avolition. The curriculum requires a critical evaluation of the DSM-5 and ICD-10 systems, focusing on the reliability and validity of diagnosis.
Activity 01
In small groups, students are given 'patient files' with a mix of symptoms. They must use simplified versions of the DSM-5 and ICD-10 criteria to reach a diagnosis, then compare results to see if different systems lead to different outcomes.
What are the key positive and negative symptoms of schizophrenia?
Activity 02
Students are given a list of symptoms. Individually, they categorise them as positive or negative; in pairs, they must explain the 'excess vs deficit' rule for each; finally, they share why negative symptoms are often harder to treat.
How reliable is the clinical diagnosis of schizophrenia?
Activity 03
Divide the class into two groups. One side argues that schizophrenia is a valid, distinct clinical entity, while the other argues it is a 'bucket' category for unrelated symptoms, using evidence of symptom overlap and co-morbidity.
What are the issues of symptom overlap and co-morbidity?
A few notes on teaching this unit
Watch Out for These Misconceptions
Schizophrenia means having a 'split personality.'
This is a common media myth. Schizophrenia involves a 'split' from reality, not multiple personalities (which is Dissociative Identity Disorder). Using clear symptom-sorting activities helps students distinguish between these very different conditions.
Diagnosis is a purely objective, scientific process.
Diagnosis often involves subjective judgement, leading to issues with inter-rater reliability. By participating in diagnostic simulations, students see firsthand how two clinicians might interpret the same symptom differently, surfacing the issue of reliability.
Methods used in this brief
Biological Explanations and Therapies
This topic examines the genetic basis, dopamine hypothesis, and neural correlates of schizophrenia. Students will also evaluate the effectiveness and side effects of typical and atypical antipsychotic drugs.
8 methodologies
Psychological Explanations and Therapies
Students explore family dysfunction and cognitive explanations for schizophrenia. They will assess the use of cognitive behavioural therapy (CBT), family therapy, and token economies in managing the condition.
