The present study aimed to assess four mediators of the association between child maltreatment and sleep in a sample of college students. Informed by the hyperarousal model of insomnia, we hypothesized that greater daily rumination, lower perceptions of perceived present control over daily stressors, poorer sleep hygiene, and greater psychological distress would mediate the relation between maltreatment and sleep. The hypothesized model was compared to an alternate path reversal model. Participants (N = 227) electronically completed a self-report measure of childhood maltreatment (baseline) and daily diary surveys assessing rumination, present control, sleep hygiene, and distress for 14 days. Daily measures were aggregated across the 14 days of assessment. Structural equation models were used to test hypotheses. Child maltreatment was significantly associated with greater sleep disturbance. Sleep hygiene partially mediated the association between maltreatment and sleep, whereas the indirect effects of maltreatment on sleep through rumination, present control, and distress were nonsignificant. Results from the alternate path reversal model demonstrated that sleep disturbance mediated the relation between child maltreatment and sleep hygiene and present control, respectively, and sleep disturbance partially mediated the relation between maltreatment and distress and rumination. Results are discussed in the context of previous research and future implications, including informing interventions on university campuses.enchild maltreatmentcollege studentsdistressruminationsleepsleep hygieneThesis or Dissertation
