Examining Diet- and Exercise-Related Communication in Romantic Relationships: Associations With Health Behaviors

This study examined the association between diet- and exercise-related social influence and support among romantic partners, as well as whether these variables were associated with their health behaviors. An Actor-Partner Mediator Model was used to examine these associations at the couple level (n = 192). Results indicated that individuals who felt their partners used more positive influence strategies also reported feeling more supported by their partners. Further, men who reported feeling more supported by their partners also engaged in healthier diet and exercise behaviors. Overall, the results suggested that people's perceptions of positive communication (i.e., influence and support) from their partners were generally more likely to be associated with their enactment of healthier behaviors. Implications for intrapersonal as well as interpersonal effects of influence, support, and health behaviors are discussed.
