  • Evaluation of Psychological Therapies for Treating SZ
    • Family Therapy
      • Appropriate?
        • Dependent on whether the family are willing to engage with it & be supported
        • Most appropraite for those with high EE levels which are likely to be problematic
        • Most appropriate when used as part of a holistic package with other therapies such as medication, as previous research suggests that biological factors such as genes are linked to SZ
      • Effective?
        • Falloon et Al
          • 36 SZic's who were at risk of relapsing & lived with High EE relatives. Found that those who were given 3 months of intense family therapy with 6 months follow up were less likely to relapse than those who had been given brief family counselling.
            • Suggesting that Family Therapy is effective
        • Leff et Al
          • 24 SZic's with high EE relatives & treated them with family therapy at home, and compared them to a control group who had regular hospital follow up & had little contact with their family. Leff found significantly fewer relapses for the family therapy group after nine months
            • Suggesting that treating SZic's with family therapy at home was more effective than regular hospital follow ups
        • Yes, when done regularly with long term follow ups, most effective when used in conjunction with other therapies as part of a holistic package, it is unlikely to be successful on its own as family dynamics are unlikely to be the root cause of SZ
    • Cognitive Behavioural Therapy
      • Effective?
        • Morrison et Al
          • 74 SZic's , CBT reduced symptoms & improved personal and social function. CBT had a similar effect to anti psychotic medication, but CBT was most effective when used with drugs, however it was better than nothing
            • Suggesting that for CBT is effective, but for the best result is should be used as part of a holistic package with drugs
        • Turkington et Al
          • Nurses were trained in CBT, and found that CBT was effective in helping clients understand their symptoms & reduce overall symptoms
            • Suggesting that CBT is effective
        • Contradictory Evidence
          • Some data may be contradictory and may lack scientific credibility, as there was no blind conditions the experimenter might be bias
            • Sensky & Lewis found no significant advantage
              • When results are pooled, effect size is close to zero, meaning that CBT may not be effective for everyone & individual differences might have an affect on effectiveness
            • Tarries found a non-significant difference when treating delusions and hallucinations & no difference for negative symptoms
              • When results are pooled, effect size is close to zero, meaning that CBT may not be effective for everyone & individual differences might have an affect on effectiveness
        • Yes, to an extent because there is nothing to lose if the CBT does not have an effect
      • Appropriate?
        • Turkington et Al
          • CBT was acceptable to patients, average rate of 12-15% drop outs, suggesting that it was accepted by patients
        • Offers hope to non-compliant or unresponsive to medication patients
        • Gives clients some control over symptoms resulting in them not becoming passive recipients of care, ore holistic when combined with drugs
        • CBT is not appropriate hen used as an alternative to medicines, used most effectively in addition to medication
        • Reduces the likelihood of being admitted or readmitted to hopsital
        • Yes, when used holistically with drugs, if just CBT is used the biological factors of SZ are under estimated
