CONSORT flow diagram for enrollment of potentially eligible participants. Eligible individuals were identified by screening survey of persons with osteoarthritis visits (N = 3,321); 1,210 respondents (36%) reported clinically significant arthritis pain and insomnia, and 998 of 1,210 persons initially eligible (82.5%) agreed to medical record review and contact by the study. “Baseline missing” is the number of individuals excluded because of missing baseline information; “2, 9 mo missing” is the number excluded because they were missing 2- and 9-month follow-up information. CBT-P = cognitive–behavioral therapy for pain; CBT-PI = cognitive–behavioral therapy for pain and insomnia; EOC = education-only control.
