This study aims to test the efficacy of an abbreviated version of Imagery Rehearsal Therapy administered by non-mental health professionals in a Primary Care setting. This treatment, to be called 'Nightmare Rescripting and Rehearsal Therapy' (NRRT) would arm Primary Care medical personnel with a nonpharmacologic, ten minute intervention for treating recurring nightmares.

The study will provide sleep hygiene education to both the control and experiment groups, NRRT to the experiment group only, and compare their Nightmare Distress Questionnaire and Nightmare Frequency Tool at two (2), four (4), and six (6) week intervals.


This is a prospective Randomized Controlled Trial to determine if a standard of care sleep hygiene handout plus a brief 10 minute intervention for recurring nightmares (Nightmare Rescripting and Rehearsal Therapy) reduces scores on the Nightmare Distress Questionnaire and Nightmare Frequency Tool, when compared to patients solely receiving a handout outlining sleep hygiene techniques. Individuals with a minimum score on the Nightmare Distress Questionnaire and Nightmare Frequency Tool of 15 out of a possible 52 who meet all other inclusion criteria will be invited to participate.

A clinically significant reduction will be considered if a decrease in Nightmare Distress and Frequency measures is greater than or equal to 25% from baseline. Secondary outcomes will include PCL-5 (PTSD), PHQ9 (Depression), GAD7 (Anxiety), ISI (Insomnia Severity Index) scores.
