their own behavior toward their partner. Thus, each measure comprised four scales—both father and mother reporting on self and other behavior. Regarding couple conflict, each seven-item scale showed good internal consistency (α = .89–.84) and the four scales had a high mean inter-item correlation (r = .62). These four scales were averaged to create a couple conflict composite. Higher scores indicated greater couple conflict. Regarding couple positivity, each four-item scale showed good internal consistency (α = .90–.92), and the four scores were also highly intercorrelated (r = .57). These four scales were averaged to create a couple positivity composite. For both measures, only mother report was included for cases missing father report (N = 62).
