Sleep disorders in early childhood: association with insecure maternal attachment.

Psychological, family, and social characteristics relating to attachment relationships were measured in mothers of 20 sleep-disordered toddlers, comparing them with 21 mothers of toddlers without sleep problems. The groups were matched on measures of socioeconomic status, child and maternal age, maternal education, marital status, and family size. Results showed that 100% of mothers of sleep-disordered children were classified as insecure with respect to attachment, as assessed by the Adult Attachment Interview, compared with 57% of control group mothers (p less than 0.002). There were no group differences on measures of maternal defensiveness, self-esteem, marital satisfaction, and social support. These results suggest that maternal current perspectives on their relationship history, rather than general psychosocial adjustment, are crucial contributors to the onset and perpetuation of sleep disorders in early childhood.
