title: A prediction model of aerobic exercise in older adults living in a continuing-care retirement community.
abstract: OBJECTIVE
  The purpose of this study was to test a model of exercise behavior in older adults. It was hypothesized that gender, marital status, chronic illness, mental and physical health, self-efficacy and outcome expectations, fear of falling, and past exercise behavior were directly and/or indirectly associated with current exercise behavior.
  
  
  METHODS
  In this descriptive study, interviews were conducted with 201 older adults living in a continuing-care retirement community.
  
  
  RESULTS
  Twelve paths were significant, and the model accounted for 40% of the variance in exercise behavior. Self-efficacy expectations, outcome expectations, and prior exercise were directly associated with current exercise; health status, gender, and marital status were indirectly associated with current exercise behavior through self-efficacy and outcome expectations.
  
  
  CONCLUSIONS
  Recognizing and treating mental and physical health problems may directly influence self-efficacy and outcome expectations related to exercise. Moreover, interventions that strengthen self-efficacy and outcome expectations related to exercise may improve exercise behavior.
