Prospective examination of mechanisms linking minority stress and anxious/depressed affect at the event level: The roles of emotion regulation strategies and proximal minority stressors.

Abstract

Background: While studies have linked sexual minority stress with anxious/depressed affect, few studies have prospectively examined how mechanistic processes linking minority stress and anxious/depressed affect unfold in near-real time. Furthermore, studies of mechanisms have focused exclusively on rumination and proximal minority stressors (e.g., internalized stigma). This limits our understanding of other potential mechanisms, such as decreases in the use of reappraisal and reflection, strategies associated with reducing anxious/depressed affect.

Method: We used data from a 30-day ecological momentary assessment study with 429 sexual minority women and gender diverse sexual minorities assigned female at birth to determine whether concurrent and prospective event-level associations between minority stress and anxious/depressed affect were mediated by changes in six emotion regulation strategies, perceived coping efficacy, and proximal stressors.

Results: In partially lagged analyses, when individuals experienced enacted or internalized stigma, they reported increased rumination and expressive suppression on the same day, which predicted increases in anxious/depressed affect into the next day. Decreases in reappraisal also mediated partially lagged associations between internalized stigma and anxious/depressed affect. Fully lagged mediation was only demonstrated for rumination as a mechanism linking internalized stigma with anxious/depressed affect. We found concurrent evidence for other mechanisms (i.e., perceived coping efficacy, reflection, internalized stigma, and rejection sensitivity).

Conclusions: Results provided support for the roles of rumination and expressive suppression as mechanisms of linking minority stress and anxious/depressed affect. The concurrent evidence for other mechanisms suggests that future research with more temporal resolution is necessary to determine the temporality and directionality of these associations.
