Assessment and prediction of outcome for a brief behavioral insomnia treatment program

This study examined (a) the efficacy, and (b) predictors of outcome of a brief (one to four sessions) behavioral treatment program for chronic insomnia. A total of 103 insomnia patients were treated, and outcome was assessed by a follow-up questionnaire. Outcome variables, including both nocturnal sleep parameters and measures of daytime functioning, showed significant improvement subsequent to treatment. Pretreatment sleep hygiene practices were significantly correlated with daytime fatigue and sleep latency outcome factors. Pre-and post-treatment complaints of daytime fatigue were associated with somatic complaints in general, but not with nocturnal sleep variables. Explanatory hypothesis are discussed.
