Trait Social Anxiety Moderates the Relationship Between Emotion-Regulation Strategy Switching and State Anxiety in Daily Life.

Difficulty knowing when to switch emotion regulation (ER) strategies is theorized to be a key pathway to emotion dysregulation, but relatively few studies have empirically examined this. We applied a new order-based metric to quantify how =109 socially anxious people switched between 19 different ER strategies (or chose not to regulate at all) throughout a 5-week ecological momentary assessment study yielding 12,616 observations. We tested whether state and trait anxiety reports, and their interaction, predicted differences in ER strategy switching. Results indicated that people with relatively higher social anxiety symptoms switch more often between ER strategies during periods of high average state anxiety but less often during periods of high variability in state anxiety than less socially anxious people. Interventions focused on helping socially anxious people learn how ER strategies are connected to variations in state anxiety might hold promise to increase adaptive ER switching decisions. More broadly, expanding ER switching interventions to consider the role of changing situations is an important next step.
