Trauma exposure is a known risk for sleep disruption from both nightmares and insomnia. Informed by recent research proposing specific mechanisms linking trauma to sleep disruption and between nightmares and insomnia, (Werner et al. 2021), we tested a model in which the relationship between nightmares and insomnia was mediated by fear of sleep. Study participants were college-aged women (N=497;...
OBJECTIVE Posttrauma nightmares are recurring nightmares that begin after a traumatic experience. Research has only recently begun to identify variables that predict posttrauma nightmare occurrences.

The present study aimed to investigate predictors of posttrauma nightmares. The sample...
