The Effects of an Internet-Based Imagery Rehearsal Intervention: A Randomized Controlled Trial.
Psychotherapy and Psychosomatics January 1, 2017 Annika Gieselmann, Max Böckermann, Marjolijn Sorbi et al.
Internet-based imagery rehearsal therapy (IRT) reduces nightmare frequency and distress in patients with mostly idiopathic nightmares. IRT outperformed a nightmare frequency control condition on both outcomes. Compared to a narrative control group, IRT was superior only for nightmare distress, not frequency, because describing the nightmare narrative in detail also lowered frequency. Guidance by a nightmare coach did not affect efficacy, compliance, or dropout. IRT appears effective even with minimal guidance.
