Differences in Effectiveness of the Active Living Every Day Program for Older Adults With Arthritis
Sperber, N. R., Allen, K. D., DeVellis, B. M., DeVellis, R. F., Lewis, M., & Callahan, L. F. (2013). Differences in Effectiveness of the Active Living Every Day Program for Older Adults With Arthritis. Journal of Aging and Physical Activity, 21(4), 387-401.
Objective: The authors explored whether demographic and psychosocial variables predicted differences in physical activity for participants with arthritis in a trial of Active Living Every Day (ALED). Method: Participants (N = 280) from 17 community sites were randomized into ALED or usual care. The authors assessed participant demographic characteristics, self-efficacy, outcome expectations, pain, fatigue, and depressive symptoms at baseline and physical activity frequency at 20-wk follow-up. They conducted linear regression with interaction terms (Baseline Characteristic x Randomization Group). Results: Being female (p <= .05), less depressed (p <= .05), or younger (p <= .10) was associated with more frequent post-test physical activity for ALED participants than for those with usual care. Higher education was associated with more physical activity for both ALED and usual-care groups. Discussion: ALED was particularly effective for female, younger, and less depressed participants. Further research should determine whether modifications could produce better outcomes in other subgroups
