State and Trait Emotion Regulation Diversity in Social Anxiety

Abstract

Emotion regulation (ER) diversity, defined as the variety, frequency, and evenness of ER strategies used, may predict social anxiety severity. In a sample of individuals with high ( n = 113) and low ( n = 42) social anxiety severity, we tested whether four trait ER diversity metrics predicted group membership. We generalized existing trait ER diversity calculations to repeated measures data to test whether state-level metrics (using 2 weeks of ecological momentary assessment [EMA] data) predicted social anxiety severity within the higher severity group. As hypothesized, higher trait ER diversity within avoidance-oriented strategies predicted greater likelihood of belonging to the higher severity group. At the state level, higher diversity across all ER strategies, and within and between avoidance- and approach-oriented strategies, predicted higher social anxiety severity (but only after analyses controlled for number of submitted EMAs). Only diversity within avoidance-oriented strategies was significantly correlated across trait and state levels. Findings suggest that high avoidance-oriented ER diversity may co-occur with higher social anxiety severity.
