Note. Daily measures were aggregated to person-level means. Shared problematic behavior is shared smoking (number of cigarettes per day) in Study 1, shared sedentary behavior (hours per day) in Study 2, and shared consumption of unhealthy foods (servings of foods high in fat, sugar, and/or salt per day) in Study 3. Daily closeness scored from 0 to 1 in Study 1, from 1 to 5 in Study 2, and from 0 to 100 in Study 3. Daily relationship satisfaction scored from 0 to 1 in Study 1, from 1 to 7 in Study 2, and from 0 to 100 in Study 3. Correlations between partners are presented in the diagonal.
