title: Re-evaluation of the evidence on the prognostic importance of schizophrenic and affective symptoms.
abstract: An earlier literature noted consistently that depressive symptoms appear to bode well for outcome in schizophrenia and related disorders. Although this view is psychodynamically plausible, most of the studies suggesting it have substantial shortcomings. In particular, most studies have been confounded by the effects of variations in duration and history of disorder, which have a major influence on both affective expression and outcome. A contrary view is that depressive symptoms in patients with schizophrenia and related disorders suggest an increased risk of self-harm and social dysfunction, just as these symptoms do in individuals with other disorders. The substantial risks of mortality and morbidity from self-harm, the link between suicide and depression, and the high prevalence of depressive symptoms in the acute and chronic stages of the disorder have all been documented in people diagnosed as having schizophrenia. Social influences are well known to be crucial to the course and outcome of schizophrenia. The expectations of others and patients' own attitudes to their illness are also known to influence outcome. Despite this, there is no longitudinal study of first admission patients to allow us to examine the possible intervening or other role of depression in the development of chronic disability.
