Beliefs about prescription sleep medications and interest in reducing hypnotic use: an examination of middle-aged and older adults with insomnia disorder.

STUDY OBJECTIVES: To examine beliefs about prescription sleep medications (hypnotics) among individuals with insomnia disorder seeking cognitive behavioral therapy for insomnia (CBTI) and predictors of wishing to reduce use.

METHODS: Baseline data was collected from 245 adults 50 years and older enrolled in the "RCT of the effectiveness of stepped-care sleep therapy in general practice (RESTING)" study. T-tests compared characteristics of prescription sleep medication users with those of non-users. Linear regression assessed predictors of patients' beliefs about sleep medication necessity and hypnotic-related concerns. Among users, we examined predictors of wishing to reduce sleep medications, including perceived hypnotic dependence, beliefs about medications, and demographic characteristics.

RESULTS: Users endorsed stronger beliefs about the necessity of sleep medications and less concern about potential harms than non-users ( p < .01). Stronger dysfunctional sleep-related cognitions predicted greater beliefs about necessity and concern about use ( p < .01). Patients wishing to reduce sleep medications reported greater perceived hypnotic dependence than those disinterested in reduction ( p < .001). Self-reported dependence severity was the strongest predictor of wishing to reduce use ( p = .002).

CONCLUSIONS: Despite expressing strong beliefs about necessity, and comparatively less concern about taking sleep medications, three-quarters of users wished to reduce prescription hypnotics. Results may not generalize to individuals with insomnia not seeking non-pharmacological treatments. Upon completion, the RESTING study will provide information about the extent to which therapist-led and digital CBTI contribute to prescription hypnotic reduction.
