Attachment, sleep quality, and depressed affect

This study examined the role of attachment insecurity in sleep problems among married adults (N = 78 couples). Using the Pittsburgh Sleep Quality Index and structural equation modeling, attachment anxiety was associated with higher levels of self-reported sleep difficulties for men and women, whereas attachment avoidance was not. Depressed affect was included as a control variable, and the effect of attachment anxiety remained significant. Men and women did not differ significantly in the magnitude of the effect of attachment anxiety on sleep quality. In addition, there were no cross-partner effects of attachment insecurity on sleep quality or depressed affect. Implications and future directions are discussed.
