Objectives:
The aim of the present study was to explore sleep problems in sexually abused preschoolers over a year.
Methods:
The sample consisted of 224 abused children and 83 nonabused children aged 3 to 6 years old at enrolment into the study (T1), and 85 abused children and 73 nonabused children at the second evaluation, approximately 1 year later (T2). Sleep problems were assessed using parental reports on the Child Behavior Checklist - Preschool Version.
Results:
Multivariate analysis of covariance revealed that sexually abused preschoolers presented higher scores of sleep problems than nonabused children on all items related to sleep problems at T1. Results from a regression analysis revealed that sexual abuse remained associated with higher levels of sleep problems after controlling for sociodemographical variables. At T2, abused preschoolers still presented more sleep problems than nonabused children on all but one of the sleep items. Results from a repeated measure one-way analysis of covariance revealed that abused preschoolers presented higher total sleep scores at both measurement times. Time was not associated with levels of sleep problems and sleep problems did not evolve differently for abused and nonabused children.
Conclusions:
Sexually abused preschoolers are at risk of presenting with sleep problems. These results are worrisome given the negative impacts of sleep problems on child development. Research and clinical implications are discussed.
