The Lifestyle-integrated Functional Exercise (LiFE) programme is a fall prevention programme originally taught in a resource-intensive one-to-one format with limited feasibility for large-scale implementation. The aim of this paper is to present the conceptual framework and initial feasibility evaluation of a group-based LiFE (gLiFE) format developed for large-scale implementation.
The conceptual gLiFE framework (part I) is based on three pillars, , , and . The feasibility of gLiFE was tested (part II) within a multimodal approach including quantitative questionnaires measuring safety, acceptability (1 = best to 7 = insufficient), and adherence to the LiFE activities (range = 0-14) as well as a focus group interview. Exploratory self-reported measures on behaviour change including self-determined motivation (range = 1-5), intention, planning, action control, and habit strength (range = 1-6) were assessed pre and post intervention. Data analyses were performed using descriptive statistics and qualitative content analysis.
The development process resulted in a manualised gLiFE concept containing standardised information on gLiFE's content and structure. Feasibility testing: Six older adults (median = 72.8 years, 5 female) completed the feasibility study and rated safety (median = 7.0, IQR = 0.3) and acceptability as high (median = 1, IQR = 1). Participants implemented 9.5 LiFE activities (IQR = 4.0) into their daily routines. No adverse events occurred during the study. In the focus group, the group format and LiFE activities were perceived as positive and important for maintaining strength and balance capacity. Self-determined motivation intention, planning, and habit strength were rated higher post intervention.
The developed conceptual gLiFE framework represents the basis for a gLiFE format with potential for standardised large-scale implementation. Proof-of-concept could be demonstrated in a group of community-dwelling older adults at risk of falling. The public health potential of gLiFE in terms of (cost-)effectiveness is currently being evaluated in a large trial.

生活方式整合功能锻炼（LiFE）计划是一项预防跌倒计划，最初以资源密集型的一对一形式开展，大规模实施的可行性有限。本文旨在介绍为大规模实施而开发的基于小组的LiFE（gLiFE）形式的概念框架和初步可行性评估。
gLiFE概念框架（第一部分）基于三个支柱，即[此处原文缺失三个支柱的具体内容]。gLiFE的可行性在多模式方法中进行了测试（第二部分），包括通过定量问卷测量安全性、可接受性（1 = 最佳至7 = 不足）以及对LiFE活动的依从性（范围 = 0 - 14），以及焦点小组访谈。在干预前后评估了关于行为改变的探索性自我报告测量指标，包括自我决定的动机（范围 = 1 - 5）、意图、计划、行动控制和习惯强度（范围 = 1 - 6）。使用描述性统计和定性内容分析进行数据分析。
开发过程产生了一个手册化的gLiFE概念，其中包含有关gLiFE内容和结构的标准化信息。可行性测试：六名老年人（中位数 = 72.8岁，5名女性）完成了可行性研究，对安全性（中位数 = 7.0，四分位间距 = 0.3）和可接受性的评价很高（中位数 = 1，四分位间距 = 1）。参与者将9.5项LiFE活动（四分位间距 = 4.0）纳入其日常生活中。研究期间未发生不良事件。在焦点小组中，小组形式和LiFE活动被认为对维持力量和平衡能力具有积极意义且很重要。自我决定的动机、意图、计划和习惯强度在干预后评分更高。
所开发的概念性gLiFE框架是具有标准化大规模实施潜力的gLiFE形式的基础。在一组有跌倒风险的社区居住老年人中可以证明概念验证。gLiFE在（成本 - ）效益方面的公共卫生潜力目前正在一项大型试验中进行评估。
