Practice Parameters for the Nonpharmacologic Treatment of Chronic Insomnia

TLDR

Insomnia is the most common sleep complaint, traditionally treated with medication, while behavioral approaches have existed for decades but are underused due to limited physician awareness, reimbursement challenges, and efficacy concerns, though recent experimental design advances guided by APA standards have improved evaluation of nonpharmacologic treatments. The parameters aim to review current evidence on nonpharmacologic insomnia treatments and highlight gaps in knowledge regarding optimal duration, provider role, long‑term outcomes, safety, and quality‑of‑life effects. The authors analyzed the literature, guided by a companion background review, and graded evidence per AASM and APA criteria for treatments such as stimulus control, progressive muscle relaxation, paradoxical intention, biofeedback, sleep restriction, multicomponent CBT, sleep hygiene, imagery training, and cognitive therapy. Recommendations rank stimulus control as standard, progressive muscle relaxation, paradoxical intention, and biofeedback as guideline‑level, sleep restriction and multicomponent CBT as options, while sleep hygiene, imagery training, and cognitive therapy lack sufficient evidence for single‑therapy endorsement.

Abstract

Insomnia is the most common sleep complaint reported to physicians. Treatment has traditionally involved medication. Behavioral approaches have been available for decades, but lack of physician awareness and training, difficulty in obtaining reimbursements, and questions about efficacy have limited their use. These practice parameters review the current evidence with regards to a variety of nonpharmacologic treatments for insomnia. Using a companion paper which provides a background review, the available literature was analyzed. The evidence was graded by previously reported criteria of the American Academy of Sleep Medicine with references to American Psychological Association criteria. Treatments considered include: stimulus control, progressive muscle relaxation, paradoxical intention, biofeedback, sleep restriction, multicomponent cognitive behavioral therapy, sleep hygiene education, imagery training, and cognitive therapy. Improved experimental design has significantly advanced the process of evaluation of nonpharmacologic treatments for insomnia using guidelines outlined by the American Psychological Association (APA). Recommendations for individual therapies using the American Academy of Sleep Medicine recommendation levels for each are: Stimulus Control (Standard); Progressive Muscle Relaxation, Paradoxical Intention, and Biofeedback (Guidelines); Sleep Restriction, and Multicomponent Cognitive Behavioral Therapy (Options); Sleep Hygiene Education, Imagery Training, and Cognitive Therapy had insufficient evidence to be recommended as a single therapy. Optimal duration of therapy, who should perform the treatments, long term outcomes and safety concerns, and the effect of treatment on quality of life are questions in need of future research.
