Abstract
Imagery Rehearsal Therapy （IRT）, Imagery Rescripting （IRS）, and Exposure, Relaxation, and Rescripting Therapy （ERRT） are typical non-pharmacological treatments for managing nightmares in patients with Posttraumatic Stress Disorder （PTSD）. A recent meta-analysis indicated that imagery rehearsal had medium to large effect on such factors as nightmare frequency, sleep quality, and PTSD symptoms. The clinical implications of imagery rehearsal and psychoeducational intervention using a booklet are discussed. Imagery rehearsal is one of the promising psychotherapies for managing nightmares in patients with PTSD, and further research should be carried out to identify the effectiveness of this treatment strategy in Japanese patients with PTSD.
