Mix it to fix it: Emotion regulation variability in daily life.

Emotion regulation (ER) strategies are often categorized as universally adaptive or maladaptive. However, it has recently been proposed that this view is overly simplistic: instead, adaptive ER involves applying strategies variably to meet contextual demands. Using data from four experience-sampling studies (Ns = 70, 95, 200, and 179), we tested the relationship between ER variability and negative affect (NA) in everyday life. The constantly changing demands of daily life provide a more ecologically valid context in which to test the role of variability. We calculated 2 global indicators of variability: within-strategy variability (of particular strategies across time) and between-strategy variability (across strategies at one time-point). Associations between within-strategy variability and NA were inconsistent. In contrast, when controlling for mean strategy endorsement, between-strategy variability was associated with reduced NA across both individuals and measurement occasions. This is the first evidence that variably choosing between different strategies within a situation may be adaptive in daily life. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
