Abstract or Description

This study examines frequency, overlap, and genetic and environmental influences on sleep difficulties, which are understudied in school-aged children. The Sleep Self Report and the Children's Sleep Habits Questionnaire were completed by 300 twin pairs (aged 8 years) and their parents. Child report suggested more frequent sleep problems than parent report (e.g., regular sleep onset delay was reported by 45% of children and 17% of parents). Associations between most of the sleep difficulties were small but significant (e.g., rs=.16 for parent report of bedtime resistance and sleep onset delay). Twin correlations based on parent reports suggest greater genetic influence (M=50%) than those based on child self-report (M=18%). Possible rater effects should be considered when evaluating children's sleep problems.
