Psychological aspects

Many psychological theories have been put forward over the years, particularly driving from psychoanalysis; however, concepts such as the 'schizophrenogenic mother' are no longer regarded as helpful.

In recent years, psychologists have used cognitive-behavioural models to try to understand and explain the psychotic phenomena seen in schizophrenia, suggesting, for example, that delusions may have their origin in a person's inbuilt tendency to jump to conclusions about things and to ignore conflicting evidence (this has led to the trial of cognitive-behavioural therapy in psychosis, although there is no clear evidence at present that it is effective, and it has yet to establish a place in routine clinical practice).
