Q

Beck & Rector Simplified-

what do Cognitive processing biases lead to?

A

Misattribution of consequences to causes
thoughts and ideas are attributed to external sources (such as hallucinations), or result in delusions because the individual does not realise that they are self-generated. They mistakenly regard their own thoughts as coming from someone else

Q

A

Research suggests that these delusions are associated with specific biases in reasoning about and explaining social situations.

Q

weakness of cognitive explanations of schizophrenia

A

Therefore, in order to explain the origins of Sz, they need to be combined with the biological model. cognitive theories may not be able to offer a full explanation of Sz, but they may help to explain the origins of particular symptoms. However, an advantage of the cognitive explanation is that it acknowledges biological explanations too, using neurophysical models.

Q

how could the cognitive model be too over-dependent on biological theories and approaches.

A

a criticism of the cognitive explanation is that large amounts of supporting evidence from the cognitive model of Sz have its roots in biological evidence suggesting cognitive faults must originate in biology. therefore the cognitive model may be too over-dependent on biological theories and approaches.

Q

what did the NICE review find that supports CBTp

A

this review found that when compared to antipsychotic medication, cognitive behavioural therapy was more effective in reducing syptom severity and improving levels of social functioning. this supports the view that faulty cognitions have an important influence in the development of schizophrenia

Q

weakness of CBTp- lack of access

A

CBTp is difficult to access. Despite being recommended by NICE as a treatment for

Q

how does the difficulty to access cbtp limit its effectiveness

A

This limits the effectiveness of CBTp as patients are unable to participate in the therapy. Of those who are offered CBTp, a significant number either refuse or fail to attend the therapy sessions, thus limiting its effectiveness even more.
