Understanding who is most and least likely to remain active after the completion of physical activity (PA) interventions can assist in developing more targeted and effective programs to enhance prolonged behavior change. The purpose of this study was to examine predictors of meeting PA recommendations 6 months postintervention in participants enrolled in Active for Life.
Participants from 2 behavioral PA programs [158 Active Choices (AC); 1025 Active Living Every Day (ALED)] completed surveys 6 months after completion of the active intervention. Analyses examined predictors of meeting PA recommendations at follow-up.
The following were significant predictors: In ALED: self-report health status, satisfaction with body function, and self-efficacy at baseline; PA status at posttest; changes in self-efficacy, perceived stress, and satisfaction with body function and appearance from baseline to posttest. In AC: PA status at post-test.
The ultimate goal of health promotion programs is to teach the behavioral skills necessary to sustain behavior change once an active intervention is complete. The findings from this study suggest that predicting PA behavior after cessation of PA interventions may not be straightforward, and predictor variables may operate differently in different intervention approaches.
了解在完成身体活动（PA）干预后哪些人最有可能继续保持活跃，哪些人最不可能继续保持活跃，有助于制定更有针对性和更有效的方案，以促进长期的行为改变。本研究的目的是探讨在参加“活力生活”项目的参与者中，哪些因素可以预测其在干预结束后 6 个月时达到 PA 推荐量。
来自 2 个行为 PA 项目（158 名积极选择（AC）；1025 名积极生活每一天（ALED））的参与者在完成积极干预后的 6 个月内完成了调查。分析考察了在随访中达到 PA 推荐量的预测因素。
以下因素是显著的预测因素：在 ALED 中：基线时的自我报告健康状况、对身体功能的满意度、自我效能感；后测时的 PA 状态；从基线到后测时的自我效能感、感知压力、对身体功能和外观的满意度的变化。在 AC 中：后测时的 PA 状态。
健康促进项目的最终目标是教授在积极干预结束后维持行为改变所需的行为技能。本研究的结果表明，预测 PA 干预停止后的 PA 行为可能并不简单，预测变量在不同的干预方法中可能有不同的作用。
