ORIGINAL ARTICLES

Objective Although center-based supervised physical activity interventions have proved to be successful in attenuating health declines in older adults, such methods can be costly and have limited reach. In the present study, we examined the effects of a DVD-delivered exercise intervention on self-esteem and its subdomains and the extent to which these effects were maintained. In addition, we examined whether psychological, demographic, and biological factors acted as determinants of self-esteem.

Methods Low-active, older adults (n = 307; mean [standard deviation] age =71.0 [5.1] years) were randomly assigned to a 6-month, home-based exercise program consisting of a DVD-delivered exercise intervention focused on increasing flexibility, toning, and balance (FlexToBa) or an attentional control DVD condition focused on healthy aging. Physical self-worth and three subdomains of self-esteem, global self-esteem, and self-efficacy were assessed at baseline, 6 months, and 12 months.

Results There was a differential effect of time for the two groups for physical self-worth (F interaction(2,530.10) = 4.17, p = .016) and perception of physical condition (F interaction(1,630.77) = 8.31, p = .004). Self-efficacy, sex, body mass index, and age were significant predictors of changes in physical self-worth and perception of physical condition.

Conclusion Our findings suggest that a DVD-delivered exercise intervention is efficacious for improving and maintaining subdomain and domain levels of self-esteem in older adults. In addition, self-efficacy was the strongest predictor of changes in physical self-worth and perceptions of physical condition. This innovative method of delivering an exercise training program via DVD is practical and effective and has the potential for broad reach and dissemination.
