A study in the March 15 issue of the Journal of Clinical Sleep Medicine evaluated a consecutive series of 50 adult patients who participated in a stepped care model for chronic insomnia, in which non-responders to a less intensive therapy received a more intensive intervention. The four-step model involved six-week computerized treatment; an on-site single-session consultation with a staff psychologist or psychological associate in the clinic; a manual-based, six-week, on-site cognitive behavioral group treatment program; and individual psychotherapy conducted by a clinical psychologist, resident, or psychological associate in the clinic. Results show that stepped care produced a 69 percent improvement in efficiency.
