Clinical correlates of insight in schizophrenia

111 schizophrenic patients diagnosed in accordance with DSM-III were rated on Landmark's symptom checklist, on demographic variables, and on variables descriptive of the course of illness. Of the 111 patients, 108 (97.3%) showed poor insight into their illness at some time in the past and 65 (58.6%) at the time of assessment. Those presently showing poor insight were significantly (Pearson rs, p< .01, 2-tailed) more frequently rated as currently displaying poor judgement also in other matters (r =.50), as showing social withdrawal (r=.42) and poor rapport (r=.33), and as being preoccupied with their delusions or hallucinations (r=.31) and as being unreliable informants (r=.41). They usually had lower education (r=.33), their income in the last taxation year was lower (r = .47), and their work functioning was less adequate (r = .30).
