Exploring Proximal LGBTQ+ Minority Stressors within Physical Activity Contexts From a Self-Determination Theory Perspective

Background: LGBTQ+ individuals experience challenges such as discrimination and marginalization (referred to as minority stressors) that are detrimental to their mental and physical health. Specifically, proximal or internalized LGBTQ+ minority stressors may influence motivation for and willingness to participate in physical activity. Methods: The purpose of this study was to explore whether proximal LGBTQ+ minority stressors, as indicators of the social-environmental context, would relate to the basic psychological needs—motivation—physical activity pathway, as per self-determination theory. An online cross-sectional survey was completed by 778 LGBTQ+ adults. Results: Results from structural equation modelling analyses support that proximal LGBTQ+ minority stressors are associated with decreased reported need satisfaction (β = -.36) which, in turn, is associated with autonomous motivation (β = .53) and reported physical activity participation (β = .32). Conclusions: Future research focused on increasing LGBTQ+ participation in physical activity should investigate the effects of (a) reducing proximal LGBTQ+ minority stressors, and (b) better supporting LGBTQ+ adults’ autonomy, competence, and relatedness within physical activity contexts.
