Individual Differences in Expectancies for Change in Depression: Associations with Goal Pursuit and Daily Experiences.

More optimistic expectations for change in patients entering treatment often predict more favorable outcomes. However, our understanding of the nature and function of those expectancies is limited. The current study tested the proposal that optimistic expectancies among patients seeking outpatient psychotherapy for major depressive disorder may be explained in part by having a more adaptive self-regulatory style. A sample of 56 adults (78.6% female; mean age 36.5) completed measures of expectancies, depressive symptoms, and aspects of self-regulation. Participants also completed a week of experience sampling using a cell phone system that signaled them 8 random times per day for 7 days. Results were largely consistent with hypotheses. Depressed participants with more optimistic expectancies had a stronger promotion goal orientation, higher goal re-engagement, and reported greater progress on their most important personal goals; daily positive affect and positive situational appraisals were also higher. Findings may suggest a possible self-regulatory mechanism underlying optimistic expectancies for change.
