The study examined the relationship between psychiatric symptoms and
work performance for 61 subjects with a DSM-III-R diagnosis of
schizophrenia or schizoaffective disorder who participated in a work
rehabilitation program. Symptoms were assessed using the Positive and
Negative Syndrome Scale (PANSS) to predict performance on the Work
Personality Profile at three and 13 weeks of the program. Twenty-seven
percent of the variance in work performance measures could be explained by
symptom components measured by the PANSS, including the cognitive,
negative, and hostility components, but the positive component did not
predict work performance. Ratings of symptoms done concurrently with
ratings of work performance were more powerful predictors than ratings of
symptoms done at three and 13 weeks before ratings of work performance.
