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.

研究组 & 干预措施
Active Treatment Group
This group will get the AgingPLUS intervention program which addresses negative views on aging, low internal control beliefs, and deficient goal planning skills.
干预措施: AgingPLUS (Behavioral)
Active Control Group
This group will get a generic health education program, called the "10 Keys to Healthy Aging". The control program will control for the effect of social contact and will not address the intervention targets of the active treatment group. The health education program will only provide information related to some of the most important health conditions, such as cardiovascular disease, cancer, type 2 diabetes, and clinical depression, and how these conditions can be managed.
干预措施: Active Control Group (Behavioral)
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.
