Nightmare Rescripting and Rehearsal

December 10, 2025 updated by: David Moss

Nightmare Rescripting and Rehearsal: Testing a 10-Minute Intervention to Treat Recurring Distressing Dreams in Primary Care.

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.

Study Overview

Detailed Description

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Nightmare distress Questionnaire (change from nightmare distress baseline from screening at each 4 visits)
Time Frame: screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
13 questions, 0-4. 0 indicates lower level of distress and effects as related to nightmares.
screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
Nightmare Frequency in the past week (change from nightmare frequency screening baseline at each 4 visits)
Time Frame: screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
Boxes numbered one to 31. Pt circles the number corresponding to the number of days they had a nightmare in the past month.
screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Posttraumatic Stress Disorder Checklist (PTSD)
Time Frame: screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
The PCL-5 is a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD. The questionnaire is self-report and may be completed in 5-10 minutes. Lower score indicates less severity of PTSD symptoms but is broad enough to pick up a wide base of patients with possible PTSD. Higher scores indicate greater severity and also offeres greater sensitivity.
screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
Beck Depression Inventory II
Time Frame: screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
BDI-II. This questionnaire self-report and is made up of 21 groups of statements designed to measure attitudes and symptoms of depression severity. Each question has options that are scored on a scale of 0 to 3. Higher scores equals more severity of depression symptoms.
screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
General Anxiety Disorder (anxiety)
Time Frame: screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
GAD-7. Objective screening tool to use to identify severity of: (Generalized Anxiety Disorder, Panic Disorder, Social Phobia and PostTraumatic Stress Disorder). 7 questions with options 0-3 and with a higher score indicating greater symptom severity.
screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
Insomnia Severity Index (insomnia)
Time Frame: screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
ISI. Measures insomnia problems occurring in the last 2 weeks. 7 questions with added up scores. Higher score indicates greater symptom severity.
screening, visit 1 (week 0), visit 2 (week 2 +/- 1 week), visit 3 (week 4 +/- 1 week), visit 4 (week 6 +/- 1 week)
