The Dual Effects Model of Social Control suggests that partners can positively and negatively influence the health behaviors of their partner. However, the model fails to consider the impact of control on non-targeted health behaviors, such as sleep. The current study sought to expand this model by including sleep continuity and duration as outcomes related to control efforts targeting diet and exercise. Partner control and objective sleep data were collected via daily sleep diaries and Fitbit Charge HR. Regression models were used to test the direct and indirect effects of control on sleep duration and continuity and the extent to which affective response mediates this relationship. Negative control had a significant effect on negative affect, but not on sleep continuity or duration. Positive control had a significant effect on positive affective response, but the full mediation model was not supported. Recommendations for future research using the proposed model are discussed.
