简要总结
This study examines the efficacy of a psycho-educational intervention program, AgingPLUS, with regard to increasing middle-aged and older adults' engagement in physical activity.
详细描述
AgingPLUS is a multi-component intervention program that addresses negative views of aging (NVOA), low internal control beliefs, and deficient goal planning as a risk cluster that keeps adults from engaging in health-promoting behavior. The program focuses on engagement in physical activity (PA) as the health behavior of choice. Engagement in PA is widely recognized as the best non-pharmacological, non-invasive, and cost-effective method of health promotion. Yet, only 20% of the adult population meets the recommended PA guidelines. This suggests that messages about the benefits of PA alone are not effective. Rather, it is essential to address the social-cognitive and motiva-tional mechanisms that prevent adults from adopting and maintaining a regular PA regimen. NVOA, low internal control beliefs, and deficient goal planning represent such a cluster of social-cognitive and motivational mechanisms.
Given this background, the specific aims and hypotheses of the proposed research are:
Aim 1: To conduct a randomized controlled trial examining the efficacy of the AgingPLUS program.
Aim 2: To test a conceptual model of the mechanisms underlying the intervention effects.
Aim 3: To conduct a 6-month follow-up to examine the longer-term effects of AgingPLUS.

结局指标
主要结局
Increased physical activity
时间窗: This effect should be observable (1) at the Week-4 post-test, (2) the Week-8 post-test, and (3) the 6-Month post-test.
We expect that participants significantly increase their engagement in physical activity as assessed by an accelerometer.
