Characteristics Pre-post intervention study (single-group, repeated measures) Peer reviewed
Sample size 12
Population Chronic nightmare patients
Intervention Imagery rehearsal treatment (IRT)
Duration Single IRT session; assessments before and 8.5 weeks after treatment
Topics Depression Dreaming
Keywords Humans Polysomnography Retrospective studies Affect Imagination Dreams Adult Female Sleep wake disorders
Key points A single imagery rehearsal treatment session was followed by significant reductions in retrospective nightmare frequency (d = 1.06), prospective bad dream frequency (d = 0.53), and anxiety (d = 1.01) in 12 chronic nightmare patients. Sleep quality showed only minimal changes that varied by nightmare etiology, suggesting sleep improvement may emerge later in recovery.

Abstract

We investigated the impact of imagery rehearsal treatment (IRT) on nightmare frequency, psychological distress, and sleep quality using polysomnography (PSG). 12 chronic nightmare patients completed prospective dream logs, measures of psychological distress, and underwent PSG prior to and 8.5 weeks following a single IRT session. Post-treatment, significant reductions were observed in retrospective nightmare frequency (d = 1.06, p = .007), prospective bad dream frequency (d = 0.53, p = .03), and anxiety scores (d = 1.01, p = .004). Minimal sleep alterations were found post-IRT, and varied as a function of nightmare etiology. The results independently replicate the efficacy of IRT for alleviating disturbing dreams and psychological distress. Sleep improvement may occur later in the recovery process.
