Childhood maltreatment is associated with risk for sleep disturbances, including Disruptive Nocturnal Behaviours (DNBs). Yet, little is known regarding associations between specific forms of maltreatment and DNBs, or factors that mediate and moderate these associations. Data from a community sample of high-risk youth (n = 193; M = 18.87 years) indicated that self-reported emotional and sexual abuse during childhood made specific contributions to DNBs at the time of assessment. Trauma-related psychopathology mediated the effects of emotional abuse. Furthermore, executive function moderated the effects of sexual abuse. Findings suggest that distinct mechanisms underlie associations between maltreatment types and DNBs.
