{"type":"trials","record":{"id":30560,"source_id":"clinicaltrials-gov","external_id":"NCT02967185","title":"Intraindividual Variability in Sleep and Cognitive Performance in Older Adults","brief_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.","overall_status":"Completed","phases":[],"study_type":"INTERVENTIONAL","sponsor":"University of Missouri-Columbia","enrollment":62,"countries":[],"start_date":"2005-05-01","completion_date":"2008-04-01","last_update_date":"2026-06-03","source_url":"https://clinicaltrials.gov/study/NCT02967185","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
