- Evaluation of the interactionist approach
- the original diathesis stress is over simple
- there is no single schizogene
- vulnerability and stress do not have one single source
- Houston et al found child sexual trauma was a vulnerability and cannabis was the trigger
- vulnerability and stress do not have one single source
- there is no single schizogene
- Effectiveness of combination treatments
- Tarrier et al 315 patients: medication + CBT, medication + supportive counselling, control group.
- patients in the two combination groups showed lower symptom levels than those in the control group (medication only)
- no difference in hospital readmission rates

- the original diathesis stress is over simple
