| Annotation | A randomised controlled trial examined the effect of two physical activity modes on changes in self-efficacy over a 12-month period in 174 older, formerly sedentary adults (mean age 65.5 years). Participants were randomised into either an aerobic activity group or a stretching and toning group. Structural equation modelling was used to conduct multiple sample latent growth curve analyses for individual growth in exercise and physical self-efficacy over time. Results indicated a curvilinear growth pattern for both types of efficacy, with increases occurring over the first 6 months, followed by declines at 6-month follow-up. There was a significant treatment by mean level growth interaction for exercise efficacy with both groups increasing over time, but the aerobic group showed a twofold increase in growth over the stretching group. Structural analyses indicated frequency of exercise participation as a significant predictor of overall growth in efficacy, and improvements in fitness were only related to exercise efficacy growth in the stretching group. Findings are discussed in terms of social cognitive theory and applications of latent growth curve modelling. (RH). |
