Examining associations between body appreciation and positive well-being among young adults: A cross-sectional analysis

Interest in positive body image stems from its contrast with negative body image. Research shows self-compassion and physical activity enhance body appreciation and positive well-being, yet their interaction in young adults is not well understood. This study examined connections between self-compassion, planned physical activity and intrinsic exercise motivations in 386 adults aged 18-39 (Mage = 27.54; SD = 5.58). Path analysis and serial mediation analysis revealed positive associations between self-compassion, planned physical activity, body appreciation and positive well-being, with notable sex differences. In men, self-compassion was linked to planned physical activity through intrinsic exercise motivations, which improved positive well-being via body appreciation. For women, planned physical activity indirectly influenced positive well-being through body appreciation. These findings underscore the importance of integrating sex-specific factors into health psychology interventions aimed at promoting positive body image. They also suggest avenues for future research to enhance well-being through targeted self-compassion and physical activity strategies.
