1

What is the interactionist approach?

A broad approach explaining schizophrenia, which acknowledges that a range of factors, including biological and psychology factors are involved in the development.

2

Meehl's model (1962):

Vulnerability to schizophrenia is entirely genetic - there's a single schizogene.

Led to development of biologically based schizotypic personality.

If a person doesn't have the schizogene, no amount of stress would lead to the disorder.

3

What is the modern understanding of the distressing stress model?

Clear that many genes increase vulnerability slightly.

There are a range of factors beyond genetic, including psychological trauma.

Trauma becomes the diathesis feather than the stressor.

4

Read et al. (2001):

Proposed a neurodevelopmental model in which early trauma alters the developing brain.
Early and severe trauma such a child abuse can seriously affect brain development.

5

Houston et al.

Modern definition of stress includes anything that risks triggering schizophrenia.

6

The relation between cannabis and schizophrenia

Cannabis is a stressor that increases the risk of schizophrenia by up to 7x according to the dose.
Cannabis interferes with the dopamine system.

Tarrier et al. (2004):

-patients in combination groups showed lower symptom levels
- no difference in rates of hospital readmission
