The role of effort, cognitive expectancy appraisals and coping style in the maintenance of the negative symptoms of schizophrenia.

The aim of the present study was to assess the role of psychological factors, specifically effort, coping, and negative expectancy appraisals, in addition to executive functioning and depression, in accounting for negative symptoms broadly defined. Fifty inpatients with acute schizophrenia participated in a study with a cross-sectional design. All of the psychological variables had significant partial correlations with some of the measures of negative symptoms when depression was controlled.
