The Effect of a Group Support Enhancing Self-Management Program on Lifestyle Modification Behaviors among Indonesian Older Adults with Knee Osteoarthritis

Osteoarthritis, as a common type of degenerative joint disease, puts older adults at high risk. It could impact the wellbeing of older adults, including physical, psychological, social, and economic factors. The aim of this study was to examine the effect of group support enhancing a self-management program on lifestyle modification behaviors among Indonesian older adults with knee osteoarthritis. Seventy-nine participants who met the inclusion criteria were recruited and assigned into the experimental group and the control group. Lifestyle modification behavior was measured during the first week, and after 6 weeks, of the program by using a Lifestyle Modification Behaviors Questionnaire (LMBQ). The internal consistency reliability coefficient of the LMBQ was 0.84. An independent t-test was conducted to examine the between group effect of the program. There was a statistically significant difference in lifestyle modification behaviors between the experimental group and the control group after receiving the program (t = 18.19, p = < 0.05). The group support enhancing self-management program effectively improved lifestyle modification behaviors among Indonesian older adults with knee osteoarthritis.
