• Psychological Treatments: CBT - Research Support

  Startup et al found that after 1 year of CBT, sufferers were much better able at managing and controlling their symptoms. Recent clinical trials found that CBT used alongside medication can enhance the benefits of drug therapy. High external validity and real world application.
• Psychological Treatments: CBT - Doesn't benefit everyone

  Lynch conducted a meta-analysis and found that CBT alone is not effective and relapse was high, suggesting it is best used in conjunction with drug therapy. CBT only deals with behaviour symptoms, not cognitive symptoms. Therefore, CBT may only be a short-term, surface level solution that does not deal with the cause of SZ. Limited validity.
• Psychological Treatments: FT Research Support

  Lam et al found that after 1 year of family therapy, relapse rates ranged from 6-23% compared to a control of 40-53%. Family therapy is a consistent treatment of SZ. However, this sample size was small, using mainly western participants and greatly suffered from participant attrition. Therefore, only tentative conclusions can be drawn from this study, as there is a limited representation of ethnic and cultural groups. Lack ecological validity and generalisability.
• Psychological Treatments: TE - Research Support

  Allyon and Azrin studied patients who had been hospitalised for 16+ years and found that they had been able to increase their daily chores from 5 to 40 a day.
• Psychological Treatments: TE - Reduces Symptoms

  Token economies have proven to reduce symptoms such as avolition and lack of motivation as it gives patients the incentive to behave more appropriately. However, the effects of a token economy may only be present when it is in effect and is unlikely to have a long-term impact. Limited reliability
