Measuring emotion dysregulation in daily life: an experience sampling study

BackgroundLiterature underscores the importance of emotion dysregulation in clinical research. However, one critical limitation of the existing investigations in this area involves the lack of psychometrically valid measures for assessing emotion dysregulation in individuals' daily lives. This study examined the factor structure and psychometric properties of momentary versions of the Difficulties in Emotion Regulation Scale (mDERS) and the Difficulties in Emotion Regulation Scale-Positive (mDERS-P).MethodsParticipants were 145 community women (M age = 40.66, 40.7% white) experiencing intimate partner violence and using substances who participated in a baseline interview and then completed surveys three times a day for 30 days.ResultsAnalyses supported the reliability of the mDERS and the mDERS-P. The two-state, two-trait model, with separate factors for negative and positive emotion dysregulation at both the within-and between-levels, fit the data best. Momentary negative, but not positive, emotions were positively related to the mDERS; both momentary negative and positive emotions were positively related to the mDERS-P. Baseline trait negative, but not positive, emotion dysregulation, was related to greater variability in momentary negative and positive emotion dysregulation.ConclusionFindings advance our understanding and measurement of emotion dysregulation using intensive longitudinal approaches.
