Relaxation therapy was given to 3 groups of older women (N = 57): (a) hypnotically medicated insomniacs, (b) nonhypnotically medicated insomniacs, and (c) noninsomniacs. Groups b and c were receiving antihypertensives. Self-reported sleep and medication data were collected for 1 week at pretreatment (except relaxation), posttreatment, and 6-weeks follow-up. Three relaxation sessions, a nondemanding, hybrid method, were administered with the rationale of helping insomnia or high blood pressure. Substantial sleep improvement occurred only for nonhypnotically medicated insomniacs. Substantial sleep medication reduction (47%) occurred only for hypnotically medicated insomniacs. This relaxation approach proved valuable, but the nature of the treatment effect was dependent on the medication status of the insomniac.
