Feasibility and Efficacy of the AgingPlus Program: Changing Views on Aging to Increase Physical Activity.

This study evaluated the feasibility and efficacy of the AgingPlus intervention program. AgingPlus is an 8-week multi-component motivational program which promotes increased physical activity by targeting adults' negative views on aging (NVOA) and perceptions of control, two known psychological barriers to physical exercise. A total of 62 adults, ages 50-82 years, participated in this feasibility study. We assessed NVOA, perceptions of control, and physical activity level at baseline (Week 0), immediate posttest (Week 4), and delayed posttest (Week 12). High attendance rates, low attrition, and positive participant feedback indicated that the program had high acceptability. Repeated measures multivariate analyses of variance (RM-MANOVA) showed statistically significant and substantively meaningful improvements in NVOA, control beliefs, and physical activity from pretest to immediate and delayed posttest. The program effects did not differ between those younger or older than age 65. These findings provide promising support for the feasibility and efficacy of the AgingPlus program.
