How Does Social Support Help Build Healthy Habits? Understanding Social Support and Its Mechanisms of Action

Perceived social support, broadly defined as resources or assistance provided by another person, has been consistently identified as a predictor of health and well-being. These outcomes may be partially explained by direct physiological effects, or the effects of perceived social support on psychological mechanisms that influence engagement in health behaviors, though what exactly these mechanisms are remains unclear. Previous work has proposed that through enhanced self-efficacy and self-esteem, perceived social support increases engagement in health behaviors, though direct evidence for this relationship is limited. Attachment, which plays a crucial role in healthy romantic relationships, may relate to social support’s influence on behavioral outcomes. This study utilized a novel social support priming task to examine if attachment-related working models of romantic partners mediate the relationships among different forms of social support, self-efficacy, and self-esteem in predicting behavioral intentions for self-nominated health goals. Broadly, primed social support positively predicted how supported individuals felt, which in turn predicted working models of their romantic partners. Working models significantly predicted self-esteem, self-efficacy, and intentions to work toward a personally relevant health goal. Self-esteem and self-efficacy also predicted behavioral intentions.
