The association between the selection and effectiveness of emotion regulation strategies and psychopathological features: A daily life study.

Emotion dysregulation is central to psychopathological conditions, including borderline personality disorder (BPD) and depression. However, the nature of emotion regulation (ER) difficulties in the daily life of people with BPD or depressive features is still unclear. Therefore, this study aimed to disentangle two different ER subprocesses in daily life: (1) selection of ER strategies, and (2) the effectiveness of implementing strategies, in terms of their associations with subsequent emotional experience. We analyzed data from a 3-wave longitudinal experience sampling study of young adults with varying levels of psychopathological features (N=202). BPD symptomatology was uniquely linked to the use, but not altered effectiveness of several putatively adaptive and maladaptive ER strategies. Depressive features were uniquely associated with the use of putatively maladaptive strategies. These findings suggest that ER deficits in people with more BPD or depressive features may be primarily located in strategy selection, rather than the implementation of those strategies.
