Effects of Social Control on Eating and Relational Behaviors in Romantic Relationships

Abstract

Abstract Background Prior research has shown that social control strategies can have either positive or negative effects on individuals’ health behaviors. However, no research has examined the degree to which social control attempts enacted by romantic partners are associated with individuals’ relational behaviors or whether perceptions of a partner’s motivation to engage in social control moderate links between the use of social control and either health or relational behaviors. Purpose This study investigated (a) the degree to which two classes of social control strategies that romantic partners can use to improve their partners’ eating behavior (autonomy-supportive and autonomy-limiting strategies) are associated with eating and relational behaviors, and (b) whether perceptions of the partner’s motivation for using social control moderate associations between its use and an individual’s eating and relational behavior. Methods This study had a daily diary design. One hundred and forty-seven individuals in romantic relationships completed surveys for 14 consecutive days. Results On days when individuals reported that their partner used autonomy-supportive social control strategies, individuals reported healthier eating and more constructive relational behaviors. There were no effects of autonomy-limiting strategies on eating or relational behavior. Perceptions of a partner’s motives did not moderate associations between reported social control and any behavioral outcomes. Moreover, there were no effects of either reported social control strategies or partner motive perceptions across time. Conclusion Romantic partners’ perceived use of autonomy-supportive—but not autonomy-limiting—social control has benefits for individuals’ health behaviors without incurring notable costs to their romantic relationship.
