Randomized controlled trial to dismantle exposure, relaxation, and rescripting therapy (ERRT) for trauma-related nightmares.

Findings indicate that ERRT with and without nightmare exposure and rescripting can significantly alleviate nightmares and related distress. The addition of nightmare exposure and rescription did not contribute incrementally to outcomes in this sample. It is possible that the dose of exposure was not sufficient to result in group differences or that the treatment components included in both conditions (i.e., psychoeducation about trauma, nightmares, and sleep; sleep habit modification; and relaxation training) may adequately treat factors that maintain nightmares for some individuals. Theoretical implications of findings are discussed. The reduction of symptoms of other conditions following this brief intervention provides further evidence for the primary role of nightmares and sleep disturbances posttrauma.
