A total of 364 schizophrenic outpatients who were stabilized for 3 months on continuous neuroleptic therapy after discharge from the hospital were rated according to three different scales for depressive syndromes (Brief Psychiatric Rating Scale anxious depression factor, AMDP/depression, and the self-rating PD-S depression scale). Between 19.5 and 27.5 of the patients were rated as depressed, or 35.7–42.8, when mild depressive syndromes were included. There were low, but significant correlations between demographic or life-event data and depression scores on the self-rating scale, whereas fewer correlations were found on the observer ratings. No associations were found between social adjustment and depression. Moderate correlations were found between measures of the apathetic syndrome and depression ratings, while observer ratings showed higher correlations than the self-rating. High depression scores, especially in the observer ratings, correlated with scales for global psychopathological assessment (CGI, GAS). There were significant correlations between extrapyramidal rigidity and observer rating depression scores, whereas the total amount of neuroleptics given had no influence. These results are interpreted on the basis of hypotheses about depressive syndromes in schizophreni
