To examine the impact of telephone reinforcement (TR) on predictors of physical activity (PA) maintenance in older adults with osteoarthritis.
Mixed effects modeling was conducted of data from a randomized PA trial that used negotiated maintenance contracts, supplemented by TR, to test impact of TR on barriers, decisional balance, and stage of change at multiple points in time.
Participants who were referred to a PA program and received TR improved the most in barriers and decisional balance. Participants who negotiated a tailored maintenance contract but did not receive TR improved the most in stage.
TR appears to positively affect perceptions around engagement, whereas negotiation positively impacts PA behavior. Further research should examine the effectiveness of specific PA maintenance strategies.
探讨电话强化(TR)对骨关节炎老年患者身体活动(PA)维持预测因素的影响。
对一项随机PA试验的数据进行混合效应建模,该试验使用协商维持合同,并辅以TR,以测试TR在多个时间点对障碍、决策平衡和改变阶段的影响。
被转介至PA项目并接受TR的参与者在障碍和决策平衡方面改善最大。协商了量身定制的维持合同但未接受TR的参与者在阶段方面改善最大。
TR似乎对参与相关的认知有积极影响,而协商对PA行为有积极影响。进一步的研究应考察特定PA维持策略的有效性。
