The purpose of this quasi-experimental, pre-post-test study was to test the effectiveness of the Deaf Heart Health Intervention (DHHI) in increasing self-efficacy for health-related behaviors among culturally deaf adults. The DHHI targets modifiable risk factors for cardiovascular disease. A sample of 84 participants completed time-1 and time-2 data collection. The sign language version of the Self-Rated Abilities Scale for Health Practices (SRAHP) was used to measure self-efficacy for nutrition, psychological well-being/stress management, physical activity/exercise, and responsible health practices. Total self-efficacy scores were significantly higher in the intervention group than in the comparison group at time-2, controlling for scores at baseline (F [1, 81] =26.02, p < .001). Results support the development of interventions specifically tailored for culturally deaf adults to increase their self-efficacy for health behaviors.
