Intraindividual Variability in Sleep and Cognitive Performance in Older Adults
Sponsor: University of Missouri-Columbia
Summary
The proposed study will examine changes in older insomniacs' cognitive functioning following behavioral treatment for insomnia using a combination of two methods. A traditional repeated measures design will be used to look at group level differences based on performance on a neuropsychological battery administered prior to, immediately after, and 3 months after completing a 4 week behavioral treatment program for insomnia. This data will be analyzed using standard repeated measures analytic techniques. A time-series design will also be used to look at within-subject differences based on a brief cognitive battery that will be self-administered on a daily basis. Data from this daily battery will be examined using intraindividual variability modeling.

Brief Behavioral Therapy for Insomnia
Treatment will consist of 4 weekly, 1 hour sessions and will be conducted by a trained graduate assistant on an individual basis. Treatment components will include education about aging and sleep. It will also include instruction in techniques designed to: (a) promote good sleep habits, (b) restrict the use of the bed and bedroom to sleep and sleep-conducive activities, (c) modify bed and wake times to better match the participants sleep needs, and (d) promote relaxation. Daily home practice of these techniques will be encouraged. Participants will maintain logs of their home practice sessions and will continue to record their daily sleep habits throughout treatment.
