Family accommodation mediates nightmares and sleep-related problems in anxious children.

Nightmares are commonly reported in clinically anxious children and are associated with the presence of other sleep-related problems. Family accommodation has been theorized as playing a central role in the sleep-related problems of anxious children, but empirical data is lacking. We examined associations between nightmares, maternal reports of family accommodation, and sleep-related problems in clinically anxious children. We also examined a hypothesized mediational pathway linking nightmares to other sleep-related problems, through increased family accommodation using structural equation modeling. Participants were 277 clinically anxious children (ages 6-17), and their mothers. Nightmares were reported in over three quarters of the children and were linked to higher mother-rated accommodation and to sleep-related problems. Fit indices for the structural equation model were excellent, and data supported the hypothesis that family accommodation mediates the association between nightmares and sleep-related problems in the anxious children. Results provide the first empirical evidence for the role of family accommodation in nightmares and other sleep-related problems in anxious children. Implications for assessment and treatment of childhood anxiety are discussed.
