effectiveness

• evidence shows that CBT is effective at treating psychological disorders
• Kuipers et al- 60 medically resistant SZ patients were given CBT and SC or just SC and 9 months later, 50% in CBT had improved compares to 31%
• CBT is not very effective when the 'input' is a realistic stressor
• Simons argues that the cause of depression or anxiety can be negative life events like bereavement so it may not be possible to think about them more positively
• The effectiveness of CBT is partly due to how good the therapist is
• Kuyken & Tsivriko - 15% of the variance in the success of CBT may be due to therapist competence so success is partly due to individual differences
