Responses to Positive Affect: A Self-Report Measure of Rumination and Dampening.

Rumination in response to dysphoric moods has been linked to the onset and maintenance of depressive symptoms; however, responses to positive moods have received less attention despite the theoretical roles of both positive and negative affect in mood disorders. The purpose of the present study was to develop a self-report measure of ruminative and dampening Responses to Positive Affect (RPA), which we called the RPA Questionnaire. In two psychometric studies, the three subscales of the RPA (Dampening, Self-focused positive rumination, and Emotion-focused positive rumination) demonstrated acceptable structural validity, internal consistency, and preliminary evidence of convergent and incremental validity with concurrent measures of self-esteem, depressive rumination, and depressive and manic symptoms among undergraduates. The present results suggest that future research on mood disorders would benefit from measuring responses to both negative and positive moods.
