Psychological and Behavioral Interventions for Managing Insomnia Disorder: An Evidence Report for a Clinical Practice Guideline by the American College of Physicians.

BACKGROUND: Psychological and behavioral interventions are frequently used for insomnia disorder.

PURPOSE: To assess benefits and harms of psychological and behavioral interventions for insomnia disorder in adults.

DATA SOURCES: Ovid MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and PsycINFO through September 2015, supplemented with hand-searching.

STUDY SELECTION: Randomized, controlled trials of psychological or behavioral interventions that were published in English and enrolled adults with insomnia disorder lasting 4 or more weeks.

DATA EXTRACTION: Data extraction by single investigator confirmed by a second reviewer; dual investigator assessment of risk of bias; consensus determination of strength of evidence.

DATA SYNTHESIS: Sixty trials with low to moderate risk of bias compared psychological and behavioral interventions with inactive controls or other psychological and behavioral interventions. Cognitive behavioral therapy for insomnia (CBT-I) improved posttreatment global and most sleep outcomes, often compared with information or waitlist controls (moderate-strength evidence). Use of CBT-I improved several sleep outcomes in older adults (low- to moderate-strength evidence). Multicomponent behavioral therapy improved several sleep outcomes in older adults (low- to moderate-strength evidence). Stimulus control improved 1 or 2 sleep outcomes (low-strength evidence). Evidence for other comparisons and for harms was insufficient to permit conclusions.

LIMITATIONS: A wide variety of comparisons limited the ability to pool data. Trials did not always report global outcomes and infrequently conducted remitter or responder analysis. Comparisons were often information or waitlist groups, and publication bias was possible.

CONCLUSION: Use of CBT-I improves most outcomes compared with inactive controls. Multicomponent behavioral therapy and stimulus control may improve some sleep outcomes. Evidence on other outcomes, comparisons, and long-term efficacy were limited.
