Depressive moods and marital happiness: within-person synchrony, moderators, and meaning

Recent studies using within-persons designs conceptually replicate and substantively extend prior research that has shown marital distress to be a robust risk factor for depression. The present investigation further extends this within-persons research tradition by increasing the frequency of assessments and by adding new moderators and measures in a sample of both newlywed (n = 24) and maritally distressed (n = 31) wives. In both samples, the average within-persons association between 21 daily assessments of wives' depressed mood and marital happiness approximated previous estimates of analogous effects (overall r = -.54). Wives reported worse depressive mood symptoms on days they experienced lower marital happiness, even after accounting for time and between-person variation in marital happiness. Each participant's within-persons mood and marital happiness association was then treated as a dependent variable to be predicted from theoretically relevant individual differences. Multilevel modeling showed that the negative within-person association between daily depressed mood and daily marital happiness was especially strong for women who were relatively high in depressive symptoms, who had avoidant attachment styles, and who were relatively low in marital adjustment.
