To evaluate the utility of several participant engagement indicators for predicting health changes in a church-based lifestyle intervention shown effective for improving dietary, physical activity, and clinical outcomes.
Descriptive indicators were constructed using 2 participant engagement measures - education session attendance (EDA) and exercise class attendance (EXA) - separately and combined. Relationships of 6 engagement indicators to health outcomes were tested using generalized linear mixed models.
EDA predicted 5 dietary and 1 clinical outcome, whereas EXA predicted one physical activity and one clinical outcome. The combined indicator predicted the same 7 outcomes.
Use of single engagement indicators specific to each intervention component is advocated for predicting relevant health outcome.
评估几种参与者参与度指标在预测一项基于教会的生活方式干预中健康变化方面的效用，该干预已被证明对改善饮食、身体活动和临床结果有效。
使用两种参与者参与度测量方法——教育课程出席率（EDA）和健身课程出席率（EXA）——分别构建描述性指标，并将它们合并。使用广义线性混合模型测试6种参与度指标与健康结果之间的关系。
EDA预测了5项饮食和1项临床结果，而EXA预测了1项身体活动和1项临床结果。合并指标预测了相同的7项结果。
提倡使用针对每个干预组成部分的单一参与度指标来预测相关健康结果。
