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.
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.
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.
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.

尽管基于中心的有监督体育活动干预已被证明在减缓老年人健康衰退方面是成功的,但这种方法可能成本高昂且覆盖面有限。在本研究中,我们考察了通过DVD进行的运动干预对自尊及其子领域的影响,以及这些影响的维持程度。此外,我们还考察了心理、人口统计学和生物学因素是否作为自尊的决定因素。
将低活动水平的老年人(n = 307;平均[标准差]年龄 = 71.0 [5.1]岁)随机分配到一个为期6个月的居家运动项目中,该项目包括通过DVD进行的旨在提高柔韧性、增强肌肉张力和平衡能力的运动干预(FlexToBa)或侧重于健康老龄化的注意力控制DVD组。在基线、6个月和12个月时评估身体自我价值、自尊的三个子领域、总体自尊和自我效能感。
两组在身体自我价值(F交互作用(2,530.10) = 4.17,p = .016)和身体状况感知(F交互作用(1,630.77) = 8.31,p = .004)方面存在时间差异效应。自我效能感、性别、体重指数和年龄是身体自我价值和身体状况感知变化的显著预测因素。
我们的研究结果表明通过DVD进行的运动干预对于改善和维持老年人自尊的子领域和领域水平是有效的。此外,自我效能感是身体自我价值和身体状况感知变化的最强预测因素。这种通过DVD提供运动训练项目的创新方法实用且有效,具有广泛推广和传播的潜力。
