ABSTRACT Background The formation of healthy sleep patterns is a critical component of positive adolescent development. Dysregulated sleep habits can put youth at risk for the development of a multitude of inimical outcomes, particularly among those who are exposed to a traumatic event. Design and methods The present study investigated the links between voluntary disengagement coping (e.g., avoidance, denial, wishful thinking) and sleep outcomes among 86 trauma-exposed and non-exposed adolescents between the ages of 12–17 (M age = 15.44, SD = 1.51; 41.9% female). Results The relationship between voluntary disengagement coping and sleep outcomes was significant only among trauma-exposed adolescents, such that greater use of voluntary disengagement strategies was associated with greater sleep disturbances and greater daytime dysfunction. Conclusions Targeting disengagement coping may be an important strategy to improve sleep health among trauma-exposed adolescents. Continued efforts in improving the efficacy of trauma-exposed adolescent intervention strategies are needed.
