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.
该研究调查了61名被诊断患有精神分裂症或分裂情感性障碍（依据《精神疾病诊断与统计手册第三版修订版》[DSM-III-R]）并参与工作康复项目的受试者的精神症状与工作表现之间的关系。使用阳性与阴性症状量表（PANSS）评估症状，以预测该项目第3周和第13周时在工作人格剖析表上的表现。工作表现测量指标中27%的方差可由PANSS所测量的症状成分解释，包括认知、阴性和敌对成分，但阳性成分无法预测工作表现。与工作表现评分同时进行的症状评分，比在工作表现评分前3周和13周进行的症状评分，是更强有力的预测指标。
