The sample included 120 older-adult participants who were relatively healthy and community residing. The study used a randomized pretest-posttest control group design. Findings showed that NVOA and self-efficacy beliefs did not mediate the association between the intervention and the outcome variables. We found that participants in the treatment and the control group improved their physical health, physical performance, and physical activity from the baseline assessment to the Week 8 follow-up. Additionally, the results showed that only participants in the treatment condition significantly decreased their systolic and diastolic blood pressure and significantly improved their left- and right-hand grip strength over an eight-week interval. These findings suggest that targeting NVOA and self-efficacy beliefs may be an effective strategy to optimize adults' healthy aging.born digitalmasters thesesengCopyright and other restrictions may apply.
