Behavioral treatment of chronic insomnia in psychiatrically ill patients.

BACKGROUND: Psychiatric patients often have residual intractable insomnia as a serious problem.
METHOD: Forty-eight psychiatrically ill patients (DSM-IV diagnoses) who had failed to respond to medicinal treatment for chronic insomnia were referred for and completed behavioral therapy as an adjunct to the pharmacologic treatment of their insomnia. The behavioral treatments included structured sleep hygiene, progressive muscle relaxation, stimulus control, and sleep restriction. The treatment program was accomplished in 6 sessions over 2 months. Follow-up evaluations were completed at 2, 6, and 12 months from the beginning of the treatment program. The outcome of the treatment program was evaluated in terms of the change in (1) self-reported specific sleep parameters, (2) self-ratings of sleep-related day-time state, (3) self-rating of quality of sleep, (4) the use of sleep medication, and (5) the therapist's global rating of improvement.
RESULTS: There was a statistically significant change from the baseline in all self-reported specific sleep parameters after 2 months that was sustained after 6 and 12 months. Sleep-related characteristics of daytime state showed statistically significant changes after 2 and 6 months that were maintained after 12 months. Sleep quality had a statistically significant change after 2 months, continued to improve statistically after 6 months, and was maximum after 12 months. Over half the patients (52.7%; 20 of 38) either reduced their sleep medication by half or stopped it completely. The therapist's global rating showed an improvement in 29.2% (N = 14) of patients after 2 months, 56.2% (N = 27) after 6 months, and 68.7% (N = 33) after 12 months.
CONCLUSION: The use of concomitant behavioral and pharmacologic treatment of chronic insomnia in psychiatrically ill patients results in improving sleep and sleep-related state and reduces the risk of return of insomnia for 10 months after finishing active treatment.
