Purpose: The aims of this study were to develop a motivational interviewing program for exercise improvement in persons with physical disabilitiesand to examine the effect of this motivational interviewing intervention. Methods: The study employed a nonequivalent control group pretestand posttest design. A total of 62 persons with physical disabilities (30 in the experimental group, 32 in the control group) were recruitedfrom 2 community rehabilitation centers. The experimental group received 8 sessions of a group motivational interviewing program, scheduledonce a week, with each session lasting 60 minutes. Test measures were completed before the intervention, immediately after the end of the intervention,2 weeks later, and 6 weeks after the end of the intervention. Measures included self-efficacy for exercise, decisional balance for exercise,stage of change for exercise, regularity of exercise, exercise maintenance, and independent living ability. Data were analyzed using thec2-test, Fisher’s exact test, Independent samples t-test, and repeated measures ANOVA, conducted using IBM SPSS Statistics version 18. Results:The experimental group showed a significant increase in self-efficacy for exercise (F=50.98, pqqqlt;.001), benefit (pros) of exercise (F=24.16, pqqqlt;.001),and independent living ability (F=50.94, pqqqlt;.001), and a significant decrease in loss (cons) of exercise (F=26.50, pqqqlt;.001). There were significant differencesbetween the two groups in stages of change for exercise (pqqqlt;.001), regularity of exercise (pqqqlt;.001), and exercise maintenance (c2=26.61,pqqqlt;.001). Conclusion: The motivational interviewing program has the potential to improve exercise levels in persons with physical disabilities.
