The benefit of nonpharmacological interventions for insomnia in old age is investigated. A total of 13 single-outcome studies involving 388 patients (mean age exceeding 60 years, minimum age in sample, 50 years) were included in a meta-analysis of treatment efficacy. This analysis demonstrated that behavioral interventions produce improvements in sleep parameters of older insomniacs, measured in terms of sleep-onset latency, number of nocturnal awakenings, time awake after sleep onset, and total sleep time. Clinical improvements seen at posttreatment were maintained at followups (averaging 6 months). It is concluded that behavioral treatments produce significant and long-lasting improvements in the sleep pattern of older insomniacs. Suggestions for future research are outlined.
