Exploring Proximal LGBTQ plus Minority Stressors Within Physical Activity Contexts from a Self-determination Theory Perspective

Background LGBTQ+ (lesbian, gay, bisexual, transgender, queer, etc.) 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. Purpose To explore whether proximal LGBTQ+ minority stressors relate to the basic psychological needs-motivation-physical activity pathway, as per self-determination theory. Methods An online cross-sectional survey was completed by 778 self-identified LGBTQ+ adults. Structural equation modelling analyses were used to examine how proximal LGBTQ+ minority stressors relate to the motivational sequence. Results Findings support that proximal LGBTQ+ minority stressors are negatively associated with psychological need satisfaction within physical activity (beta = -.36), which in turn is positively associated with autonomous motivation (beta = .53) and reported physical activity participation (beta = .32). Overall, the final model accounted for 13% of variance in need satisfaction (small effect size), 53% of variance in autonomous motivation (moderate-large effect size), and 10% of variance in moderate-to-vigorous physical activity levels (small effect size). 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.

Automated summary

This study explores the relationship between proximal LGBTQ+ minority stressors and the basic psychological needs-motivation-physical activity pathway. The findings suggest that reducing proximal LGBTQ+ minority stressors and supporting LGBTQ+ adults' autonomy, competence, and relatedness within physical activity contexts are important for increasing LGBTQ+ participation in physical activity.
