The development of attachment in separated and divorced families. Effects of overnight visitation, parent and couple variables.

This study represents the first systematic investigation of the effects on infant attachment to mother and to father of the increasingly common practice of overnight visitation (time-sharing) with the father in separated and divorced families. There were 145 infants (ages 12 to 20 months) and their mothers (and 83 fathers) who participated in the study. Parents completed questionnaires, were interviewed about their relationship with the baby, and were observed with their infants in the Strange Situation. Infants in separated/divorced families who had regular overnight visits with father (n = 44) were significantly less likely to be classified as secure and more likely to be classified as disorganized or unclassifiable in their attachment to mother than infants in a married comparison group (n = 52). Attachment classification to father was unrelated to visiting (time-sharing) arrangements, but infants were significantly more likely to be classified disorganized/unclassifiable with father in the separated/divorced groups (n = 39) than in dual-parent families (n = 44). Disorganized attachment to mother in the Overnight group was associated with maternal reports of low parent communication and high parent conflict, and with low maternal psychological protection of the infant, assessed from maternal interviews. Consistent with Bowlby's and Rutter's context-sensitive views of the effects of separation, the results suggest that repeated overnight separations from the primary caregiver are associated with disruption in mother-infant attachment when the conditions of visitation are poor, i.e. when parents are unable to provide adequate psychological support to the child.
