Background: Self-management programs have been shown to improve quality of life and self-efficacy for stroke survivors, but participation is often low. We are conducting a randomized controlled trial (RCT) of a complex, multidisciplinary, team-based intervention, SUCCEED, to improve risk factor control after stroke in a safety-net setting. Intervention participants are offered Chronic Disease Self-Management Program (CDSMP) workshops. We implemented strategies to increase participation, including monetary incentives, free transportation, workshops at community venues, inviting family and caregivers, and accommodating participants’ schedules. Objectives: To determine factors associated with participation and with extent of participation in a series of 6 sessions. Methods: From 2014 to 2017, 487 English and Spanish-speaking individuals (age>40 years) with stroke or TIA were enrolled in SUCCEED; 241 were randomized to intervention and offered CDSMP. Multivariable logistic and linear regression analyses were used to identify factors associated with CDSMP participation, including age, race/ethnicity, gender, employment status at 3 months, marital status, competing needs in 6 months prior to index stroke, life chaos, depression (PHQ-9), and disability (modified Rankin score). Results: Of 241 in the intervention arm, 29% (n=70) attended at least one CDSMP session (median sessions attended=4; IQR 2, 6). Unemployment at 3 months was associated with participation (adjusted OR=12.6, 95% CI 2.3, 69.7). Individuals were less likely to participate if they were not married or in a domestic partnership (OR=0.4, 95% CI 0.2, 0.9) or had foregone seeing a doctor in the 6 months prior to stroke because of caregiving responsibilities (OR=0.3, 95% CI 0.1, 1.0). Greater disability was associated with attendance at more sessions (p=0.03). Conclusion: Less than one third of participants attended CDSMP classes. Although we addressed financial and transportation barriers to participation, employment and caregiving responsibilities adversely impacted engagement. Spousal support was a key facilitator. Those with more severe disability were potentially more motivated to participate in CDSMP.
