Responsive methods and measures are needed to bridge research to practice and address public health issues, such as older adults' need for multicomponent physical activity. The objective of this study was to detail the longitudinal, quasi-experimental work that spans 5 years to describe outcomes across RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) dimensions of integrating a physical activity intervention for older adults into the Cooperative Extension System through the assess, plan, do, evaluate, report (APDER) cycle.
The participant-level intervention is Lifelong Improvements through Fitness Together (LIFT), an 8-week, group dynamics-based, strength-training program with 16 in-person sessions. The implementation intervention applies the iterative APDER cycle based on feedback for each dimension of RE-AIM. Each year, the APDER cycle was used to embed data collection procedures at the instructor and participant level to reveal the next evolution of the program.
Each evolution of LIFT was measured through a pretest and posttest quasi-experimental design. Data were collected on each RE-AIM dimension through participant surveys and functional fitness assessments, number and representativeness of trainees, and process evaluation.
Overall, LIFT was expanded to 4 states with 275 instructors, reaching 816 older adults; consistently improved functional fitness outcome measures; demonstrated strong program adherence; and was seen as feasible and enjoyable by instructors and participants. LIFT is now undergoing adaptations for virtual delivery as well as updating the exercise protocol to introduce yoga postures that target flexibility and balance.
Overall, ongoing adaptations were necessary to ensure the program continued to fit the mission, values, and resources of the delivery system. Public health implications to support the need for ongoing adaptation include embedding pragmatic measures of adaptations and RE-AIM into standard evaluation pathways and using iterative APDER cycles.
需要有响应性方法和措施来弥合研究与实践之间的差距,并解决公共卫生问题,例如老年人对多成分身体活动的需求。本研究的目的是详细描述跨越 5 年的纵向、准实验工作,描述将老年人身体活动干预措施纳入合作推广系统的过程中,在通过评估、计划、执行、评估、报告(APDER)周期跨越 RE-AIM(覆盖范围、效果、采用、实施和维护)维度的结果。
参与者层面的干预措施是 Lifelong Improvements through Fitness Together(LIFT),这是一个为期 8 周的、基于小组动态的力量训练计划,共有 16 次面对面课程。实施干预措施应用基于 RE-AIM 各个维度反馈的迭代 APDER 周期。每年,APDER 周期都用于在指导员和参与者层面嵌入数据收集程序,以揭示计划的下一个演变。
通过预测试和后测试准实验设计,对每个演变版本的 LIFT 进行测量。通过参与者调查和功能健身评估、培训师的数量和代表性以及过程评估,收集每个 RE-AIM 维度的数据。
总体而言,LIFT 已扩展到 4 个州,拥有 275 名指导员,覆盖了 816 名老年人;功能健身结果测量得到持续改善;表现出很强的项目依从性;并被指导员和参与者认为是可行且愉快的。LIFT 现在正在进行虚拟交付的改编以及更新锻炼方案,引入针对柔韧性和平衡的瑜伽姿势。
总体而言,持续的改编是必要的,以确保该计划继续符合交付系统的使命、价值观和资源。支持持续改编的公共卫生影响包括将适应措施和 RE-AIM 的实际测量嵌入标准评估途径,并使用迭代 APDER 周期。
