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 (β = −.36), which in turn is positively associated with autonomous motivation (β = .53) and reported physical activity participation (β = .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.

从自决理论的角度探索体育活动背景下的近端 LGBTQ+ 少数族裔压力源

背景 LGBTQ+（女同性恋、男同性恋、双性恋、跨性别者、酷儿等）个体面临歧视和边缘化（称为少数族裔压力源）等挑战，这些挑战不利于他们的身心健康。具体而言，近端或内化的 LGBTQ+ 少数族裔压力源可能会影响参与体育活动的动机和意愿。目的 根据自我决定理论，探讨近端 LGBTQ+ 少数族裔压力源是否与基本心理需求——动机——身体活动途径相关。方法 由 778 名自我认同的 LGBTQ+ 成年人完成在线横断面调查。结构方程模型分析用于检查近端 LGBTQ+ 少数族裔压力源与动机序列的关系。结果 研究结果支持，近端 LGBTQ+ 少数族裔压力源与身体活动中的心理需求满意度呈负相关（β = -.36），而后者又与自主动机（β = .53）和报告的身体活动参与（β = . 32)。总体而言，最终模型占需求满意度方差的 13%（小效应量）、自主动机方差的 53%（中-大效应量）和中等至剧烈运动水平方差的 10%（效应量小）。结论 未来的研究侧重于增加 LGBTQ+ 参与体育活动，应调查 (a) 减少近端 LGBTQ+ 少数族裔压力源和 (b) 更好地支持 LGBTQ+ 成年人在体育活动环境中的自主性、能力和相关性的影响。
