Psychosocial treatments for nightmares in adults and children: a systematic review

BACKGROUND

As nightmares may be a risk factor for, or symptom of, multiple psychological disorders, some researchers suggest that nightmares should be screened, diagnosed, and treated. Treatments for nightmares include trauma-focused Cognitive Behavioural Therapy and Image Rehearsal Therapy, and pharmacological interventions such as prazosin and nitrazepam. As recent research has put into question our current understanding of treatment efficacy, there is a need to systematically review findings related to the effectiveness of nightmare treatments to inform best practice. The current review assessed the efficacy of psychosocial treatments of nightmare in all cohorts.

METHODS

A systematic search of four databases for peer reviewed journal articles from 2000 onwards produced 69 (35 RCTs, 34 non-RCTs) eligible articles that underwent narrative synthesis.

RESULTS

The results provide strong evidence for exposure and image rehearsal treatments for the reduction of nightmare frequency, severity, and distress, in civilian, military, idiopathic, and posttraumatic stress disorder (PTSD) cohorts. There is emerging evidence that self-guided and brief treatment modalities offer efficient and effective treatment options. There is an urgent need for clinical trials of treatment effectiveness in children.

CONCLUSIONS

The results suggest that treatments for nightmares are most effective when they facilitate a sense of control or mastery by directly targeting the nightmare content and/or the client's emotional responses to the nightmare content.

TRIAL REGISTRATION

A review protocol was registered with PROSPERO (CRD42020204861).

Exposure, Relaxation, and Rescripting Therapy for Trauma-Related Nightmares With Psychiatric Inpatients: A Case Series

Research has shown that posttraumatic stress disorder (PTSD) is a highly prevalent diagnosis for psychiatric patients, yet individualized care and treatment is limited in the inpatient acute care sector. Two case studies are presented which examine the use of Exposure, Relaxation, and Rescripting Therapy (ERRT) for chronic trauma-related nightmares, within a private acute care inpatient psychiatric hospital setting. ERRT is empirically supported with efficacy for veteran and civilian populations, however no research to date has been conducted with psychiatric inpatients. Two participants diagnosed with PTSD, suffering distressing trauma-related nightmares, completed ERRT over three sessions during their psychiatric hospital admission, with the aim of reducing the frequency and severity of nightmares and related psychological symptoms. PTSD, depression, sleep quality and quantity, and nightmare frequency and related distress, were measured pre-treatment, during treatment, and follow-up at one, 3 and 6 months. Only one participant reported ongoing nightmares by the third week of the intervention, with both participants reporting an absence of nightmares at the one and 3-month follow-ups, but mixed results by the 6-month follow-up. One participant also reported a reduction in PTSD symptoms and a mild improvement in depression. The results offer some preliminary support for the provision of ERRT for the treatment of trauma-related nightmares for psychiatric inpatients.

Narrative Exposure Therapy for Treating PTSD With Psychotic Features

Posttraumatic stress disorder (PTSD) with secondary psychotic features is a syndrome that comprises PTSD symptoms followed in time by the additional appearance of psychotic features. Although diagnostic criteria for this condition are not available, the clinical description of this condition has been described especially in individuals who have experienced severe, chronic, multiple traumatic events. This case study presents the treatment of a survivor of torture with severe PTSD and concomitant psychotic features using the psychosocial approach as a theoretical framework of the clinical presentation and narrative exposure therapy (NET) as a psychotherapeutic intervention. NET could be a useful psychotherapeutic tool in relieving symptoms related to severe PTSD with secondary psychotic features. The overall implications involved in working with survivors of torture are also discussed.
