This study examined reliability of the Health Enhancement Lifestyle Profile-Screener (HELP-Screener), a 15-item self-report questionnaire serving as an initial screening of lifestyle behaviors for older adults. The internal consistency of HELP-Screener was analyzed using data derived from a sample of 483 older adults. The resultant Cronbach's α coefficient of .74 indicated an acceptable level of internal consistency. The test-retest reliability study with 90 participants yielded an intraclass correlation coefficient of .93, indicating a high degree of temporal stability of the instrument at the scale level. Moreover, good to excellent degrees of agreement found through the κ statistic (k(s) = .76-.96) and percentage of agreement (96%-99%) between the test and retest scores of each item further supported HELP-Screener's test-retest reliability at the item level. Future studies should determine other aspects of psychometric properties and clinical suitability of this new instrument.
本研究旨在检验健康促进生活方式量表-简易筛查版（HELP-Screener）的信度，该量表是一个包含 15 个项目的自我报告问卷，用于初步筛查老年人的生活方式行为。我们对 483 名老年人的样本数据进行了 HELP-Screener 的内部一致性分析。克朗巴赫 α 系数为.74，表明该量表具有可接受的内部一致性。对 90 名参与者进行的重测信度研究得到了组内相关系数为.93，表明该工具在量表水平上具有高度的时间稳定性。此外，通过κ统计量（k(s) =.76-.96）和每个项目的测试和重测得分之间的一致性百分比（96%-99%）发现了良好到极好的一致性程度，进一步支持了该新工具在项目水平上的重测信度。未来的研究应该确定这个新工具的其他心理测量学特性和临床适用性方面。
