Expectancies, mood, and performance of depressed and nondepressed psychiatric inpatients on chance and skill tasks.

The learned helplessness model of depression predicts that, compared with nondepressed patients, depressed patients will demonstrate psychomotor deficits, provide lower subjective evaluations of their performance, and perceive reinforcement in skill tasks as more response independent. These predictions were tested in 32 depressed (mean age 35 yrs) and 32 nondepressed (mean age 38 yrs) psychiatric inpatients, who had been administered the Quick Test and the Beck Depression Inventory. Ss performed card- and peg-sorting tasks in which measures of performance, ratings of mood and expectancy of success, and subjective evaluations of performance were obtained under chance and skill reinforcement conditions. Although some support was obtained for the prediction that depressives provide lower evaluations of their performance than nondepressives, the other predictions were not supported. Comparisons between depressed and nondepressed schizophrenics indicate that the mood of depressed schizophrenics was especially sensitive to task outcome for both skill and chance conditions.
