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.

Integrating research from life history theory with investigations of construal-level theory, the researcher proposes a novel relationship between life history strategy and construal-level. Slow life history strategies arise in safe, predictable environments where individuals give up current reproductive effort in favor of future reproductive effort. Correspondingly, high-level construals allow individuals to transcend the current context and act according to global concerns, such as the type of future planning necessary to enact slow life history strategies. Meanwhile, fast life history strategies arise in harsh, unpredictable environments where the future is uncertain and individuals need to pay close attention to the current context to survive. Correspondingly, low-level construals immerse individuals in the immediate situation, enabling them the flexibility needed to respond to local concerns. Given the correspondence between aspects of life history and construal-level, it seems possible that individuals adopting slow life history strategies should more frequently use high-level construals to assist in transcending the current situation to plan for the future, while individuals adopting fast life history strategies should more frequently use low-level construals to assist in monitoring the details of their harsh, unpredictable environment. To test the relationship between life history and construal, the researcher investigated whether or not a childhood cue of environmental harshness and unpredictability, childhood SES, and a current cue of environmental harshness and unpredictability, local mortality rate, influenced construal-level. In line with past research, the researcher predicted that childhood SES would interact with current cues of local mortality rate to influence construal-level. For individuals growing up in high SES households, a high local mortality rate will lead to an increase in high-level construals. For individuals growing up in low SES households, a high local mortality rate will lead to an increase in low-level construals. Overall, results did not support the hypotheses. Childhood SES did not interact with prime condition to influence either categorization or trend predictions. Examining how the prime interacted with another measure of life history strategy, the Mini-K, yielded mixed results. However, there are several ways in which the current study could be altered to reexamine the relationship between life history strategy and construal.
