Outcome Measures

Primary Outcomes (1)

  • Increased physical activity

    We expect that participants significantly increase their engagement in physical activity as assessed by an accelerometer.

    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.

Study Arms (2)

Active Treatment Group

EXPERIMENTAL

This group will get the AgingPLUS intervention program which addresses negative views on aging, low internal control beliefs, and deficient goal planning skills.

Behavioral: AgingPLUS

Active Control Group

PLACEBO COMPARATOR

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.

Behavioral: Active Control Group

Interventions

AgingPLUSBEHAVIORAL

The program consists of 2-hour meetings for a total of 4 weeks (total of 8 hours) and discusses (a) how negative views on aging and negative age stereotypes undermine adults' health-promoting behaviors; (b) how adults can take control of their own aging; and (c) how personal goals can be achieved through more effective goal planning and action plans.

Active Treatment Group
Active Control GroupBEHAVIORAL

The program consists of 2-hour meetings for a total of 4 weeks (total of 8 hours) and discusses (a) four major health conditions that affect the lives of many middle-aged and older adults (e.g., cardiovascular disease, cancer, type 2 diabetes; clinical depression); and (b) how these conditions can be managed successfully.

Active Control Group

Eligibility Criteria

Gender Eligibility DetailsParticipants will self-identify their gender orientation.
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults who engage in less than 60 minutes of PA per week and who intend starting a physical exercise program.
  • English speaking.
  • Willingness to be randomized to one of two programs.
  • Willingness to take part in the physical fitness tests and wear an accelerometer.
  • Willingness to commit to follow-up testing (i.e., not moving out of the area during the study period).
  • Physician clearance to take part in a submaximal exercise test and to begin an exercise program.

You may not qualify if:

  • Signs of cognitive decline (defined as more than 4 errors on the Short Portable Mental Status Questionnaire).
