Psychiatric Inpatient Nightmare Treatment

Summary

Nightmares are repeated extremely dysphoric and well-remembered dreams, which typically occur during REM sleep in the second half of sleep, may awaken the dreamer, and upon awakening, individuals quickly become oriented and conscious of their surroundings. Nightmares are very common in psychiatric populations. In psychiatric populations, nightmares can occur as a freestanding disorder, persist in patients after undergoing treatment for a psychiatric disorder, and function as a risk and exacerbating factor regarding psychiatric symptoms. Imagery Rehearsal Therapy (IRT) is a cognitive-behavioral-oriented treatment for nightmares and asks patients to identify an especially distressing nightmare and then works together with the patient on changing the nightmare to a more positive theme, story line, or ending. The new contents are then rehearsed using imagery techniques. IRT is often recommended by guidelines. However, IRT has not been investigated in a randomized controlled trial in the population of psychiatric inpatients. In this study, sixty inpatients with nightmares will be recruited from the inpatient units of the Psychiatric University Hospital Zurich (PUK). Participants will be randomly assigned to an Imagery Rehearsal Therapy (IRT) group or a Treatment As Usual (TAU) control group. Questionnaires and dream diaries will measure changes in nightmare frequency, nightmare distress, nightmare effects, nightmare content, overall sleep quality, dream experiences and believes, symptom severity of primary psychiatric diagnoses, and psychotherapy motivation and hopefulness one week and two weeks after one IRT or TAU session. The TAU group will receive a session in which potential problems with the dream diary will be discussed. Patients in the IRT group will be instructed to use imagery exercises with the new dream narrative for 10 to 15 minutes a day for the duration of the study period.

Interventions

BEHAVIORAL

Imagery Rehearsal Therapy

The Imagery Rehearsal Therapy (IRT) intervention used in this study is a short version of the treatment, consisting of 1-2 sessions. The protocol starts with a very brief explanation of the treatment. Then the patient will be guided through an imagery exercise. The next step is to choose a nightmare. This nightmare is then rescripted to a new narrative, which is in no way distressing to the patient anymore. Subsequently, the therapist will guide the patient through an imagery exercise with the new narrative. The new narrative is then either written down or recorded. Lastly, the therapist will explain to the patient, that he or she should rehearse the new narrative daily with imagery exercises.

BEHAVIORAL

Treatment as Usual with dream diaries

Treatment as Usual means that patients in this arm will receive usual inpatient care. Additionally, they will keep a dream diary. It has been shown in previous studies that keeping a dream diary has a positive effect on nightmares.
