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.

Physical activity has been shown to have a multitude of physical health benefits, including reduction of risk of certain illnesses and an overall improvement in physical and cognitive functioning. Current intervention techniques work to improve physical activity habits in participants through education about these long-term health benefits. However, most individuals living in the United States are not currently reaching ideal amounts of physical activity, suggesting that these interventions have not been entirely effective. Might an intervention that fosters intrinsic motivation via exercise enjoyment be more effective? The current study sought to compare a long-term health benefit-focused intervention to an alternative that focuses on immediate enjoyment of exercise. Participants were randomly assigned to one of these two intervention conditions. Participants reported their time spent doing physical activity and level of enjoyment of physical activity pre- and post-intervention. We found no significant differences between conditions. Frequency and enjoyment of physical activity increased post-intervention, regardless of condition. Future research should be done to correct the limitations of this study and gain a more accurate view into which factors are most important in exercise motivation.
