Momentary emotion regulation strategy use and success: Testing the influences of emotion intensity and habitual strategy use.

Successful emotion regulation (ER) is important for a wide range of psychosocial outcomes. Specific ER strategies have been identified as being more or less likely to be successful. However, recent evidence suggests significant individual differences in the association between strategy implementation and ER success. Indeed, 2 key factors may play an important role in moderating the link between ER strategy use and ER success in the moment: (a) the intensity of the specific emotional experience, and (b) the relative frequency in using a given ER strategy. Experience-sampling across 14-days (N = 304, M_age = 19.14, % female = 87.5) was used to assess whether emotion intensity and trait ER strategy use were differentially associated with perceived regulatory success depending on which ER strategy was used. Multilevel modeling revealed that more intense emotions were associated with lower perceived success for all strategies. Additionally, habitual reappraisal predicted greater success and habitual rumination predicted lower success. We discuss the possibility that results reflected intensity-based ER strategy choices and add to the growing call to abandon the reductive labeling of ER strategies as either "adaptive" or "maladaptive."
