The evidence for CBT

 

Effectiveness of CBT as a therapy for Psychosis

The following studies evaluate the effectiveness of CBT for Psychosis. There is solid evidence that CBT can be highly beneficial therapy to psychosis. However it must be highlighted that some researchers are disappointed about the results and conclude that CBT must not offered automatically to all people with first psychosis. However there are some surprising outcomes. People with carers seem to profit more from CBT than people without carers. This is also found by Hogerty researching his “personal therapy”. They look at outcomes at 12 and 24 months. With high quality care as usual ‘befriending’ with a treatment team maybe has a protecting effect on preventing relapse. In the Amsterdam study family intervention made a difference not after 24 months (they found few relapses) but it did after 5 years, after the time the relationship with the treatment teams was discontinued.

Consistent delivery of full therapy, including specific cognitive and behavioural techniques, was associated with clinically and statistically significant increases in months in remission, and decreases in psychotic and affective symptoms. Delivery of partial therapy involving engagement and assessment was not effective.”’

Citation: “There was a statistically significant reduction in delusional distress at 12 months for those with carers who received CBT; all other results for psychotic and emotional symptoms were non-significant, although a number of other variables indicate a consistent treatment effect that might be common to both CBT and family intervention.”

This trial found no benefits of psychological interventions, whether CBT or family intervention, for the primary outcomes of relapse and days in hospital. There were limited benefits for CBT on the secondary outcomes of improvements in depression, symptoms and social functioning.”’

CBT for Social Recovery and Negative Symptoms

Negative beliefs can foster negative symptoms in people who suffered from psychosis. In CBT they learn to challenge beliefs like:
It is difficult to be happy unless one is good looking, intelligent, rich, and creative.

  • People will probably think less of me if I make a mistake.

  • If I do not do well all the time, people will not respect me.

  • Taking even a small risk is foolish because the loss is likely to be a disaster.

  • If a person asks for help, it is a sign of weakness.

  • If I do not do as well as other people, it means I am an inferior human being.If I fail at my work, then I am a failure as a person.

  • If you cannot do something well, there is little point in doing it at all.

  • Making mistakes is fine because I can learn from them.

  • If I fail partly, it is as bad as being a complete failure.

  • People should have a reasonable likelihood of success before undertaking anything.

  • If I don't set the highest standards for myself, I am likely to end up a second-rate person.

  • If I am to be a worthwhile person, I must be truly outstanding in one major respect.

  • People who have good ideas are more worthy than those who do not.

  • If I ask a question, it makes me look inferior.

The findings support those of previous studies that highlight an important role for hope and positive self-concept in the recovery process. Moreover, the study reported here provides a bridge between consumer-oriented and evidence-based practice approaches to investigating and defining recovery. Consumer-oriented approaches highlight the importance of "renewing hope" and addressing the "interpersonal effects" of psychosis.

Defeatist beliefs as a mediator of cognitive impairment, negative symptoms, and functioning in schizophrenia.

view-article 

Conclusion: Our findings are consistent with the hypothesis that defeatist beliefs are a mediating variable between cognitive impairment, negative symptomatology, and poor functioning in schizophrenia. Patients showed more defeatist belief endorsement than healthy controls; furthermore, the inclusion of defeatist beliefs in the statistical modeling resulted in an attenuation of the association between cognitive impairment and both negative symptom levels and functioning in the patient sample.
