Background: Health behavior change models identify effective self-regulatory skills for behavioral change, but the social
context is usually neglected. This study investigated the effectiveness of a dyadic conceptualization of action control for
promoting physical activity. Methods: 121 overweight individuals and their partners were randomly allocated to one of two
experimental (dyadic vs. individual action control) and two control conditions. Participants completed questionnaires at
baseline (T1) and four weeks later (T2) including measures of action control and 7-day recall physical activity. Findings:
Results showed that action control signi+cantly increased from T1 to T2 and was overall higher in the experimental
conditions compared to control conditions. In terms of physical activity, no overall intervention effect emerged. However,
post hoc analyses revealed higher mean levels of sport activities in the dyadic intervention group compared to all other
groups. Discussion: Overall, +ndings provide +rst support for the usefulness of a dyadic action control intervention, and
suggest further investigation of objective measures of physical activity and secondary outcomes
