BACKGROUND: Exercise is effective in preventing frailty status in older adults, but the effect of an exercise program based on Wellness Motivation Theory (WMT) on the frailty status, self-efficacy for exercise, and quality of life for older adults with pre-frailty remains unclear. Our objective was to examine the efficacy of a multicomponent exercise program based on WMT on frailty status, self-efficacy, and quality of life among pre-frail older adults. METHODS: This was a randomized controlled trial of pre-frail older adults aged from 60 years to 85 years. Participants in the intervention group performed exercise three times a week for 24 weeks, once at a community health service station instructed by two researchers and two times at home. Participants in the control group were given one-time advice on physical activity. The assessor was the only one blinded. The primary outcome was the reversal rate of pre-frailty. The secondary outcomes included self-efficacy and quality of life. RESULTS: One hundred and forty-four participants were randomized into two groups (n = 72 in the intervention group and n = 72 in the control group) and analyzed. After 24 weeks, the proportion of pre-frailty was significantly lower in the intervention group than in control (31.8% versus 74.6%, p < 0.001). The absolute risk reduction was 42.8% (95% CI 25.1 to 57.1). In the 8th week and the 24th week, the frailty score of the intervention group was significantly lower than that of the control group. There were significant improvements in self-efficacy at week 2, week 8, and week 24. In weeks 8 and 24, participants in the intervention group reported a higher quality of life than the control group. There were no exercise-related injuries or falls among the participants. CONCLUSIONS: The exercise intervention based on WMT for pre-frail older adults could reverse pre-frailty, increase self-efficacy for exercise, and improve the quality of life in older Chinese. STUDY REGISTRATION DETAILS: This study was registered in www. CLINICALTRIALS: gov on the 25th of July, 2024, with the identifier NCT06519695. REPORTING METHOD: The Consolidated Standards of Reporting Trials (CONSORT) checklist was used in this study for properly reporting how the randomized trial was conducted.
