This study was conducted to develop and validate the Health Enhancement Lifestyle Profile (HELP), a self-report measure for examining various aspects of health-related lifestyle in older adults. Data derived from 253 community-dwelling older adults were analyzed through the Rasch measurement model. Unidimensionality and data-model fit of HELP were largely supported through the analyses of principal components of residuals, fit statistics, local dependency, and differential item functioning. The item hierarchy formed through logits provided an expected pattern of healthy lifestyle behaviors. Acceptable to good person separation and reliability statistics supported the clinical applicability and consistency of the HELP scores. Finally, analysis of the rating scale structure confirmed the functioning of the 0- to 5-point rating scale used. HELP can assist in monitoring lifestyle risk factors and measuring the outcome of services aimed at promoting healthy lifestyles among older adults.
本研究旨在开发和验证健康促进生活方式量表（HELP），这是一种自我报告式的测量工具，用于评估老年人健康相关生活方式的各个方面。通过 Rasch 测量模型分析了来自 253 名社区居住的老年人的数据。通过对残差的主成分分析、拟合统计、局部依赖性和差异项目功能分析，很大程度上支持了 HELP 的单维性和数据模型拟合。通过对数形成的项目层次结构提供了健康生活方式行为的预期模式。可接受的个体分离和可靠性统计数据支持 HELP 分数的临床适用性和一致性。最后，对评分量表结构的分析证实了所使用的 0 到 5 分评分量表的功能。HELP 可用于监测生活方式风险因素，并衡量旨在促进老年人健康生活方式的服务的结果。
