The purpose of this study was to develop and validate a scale to measure health behavior across the six pillars of lifestyle medicine: sleep, social connectedness, physical activity, nutrition, substance use, and stress management. A pilot study (n = 94) investigated the construct, convergent, and content validity and reliability of the Lifestyle Medicine Health Behavior (LMHB) scale. Based on the pilot study results and literature, the scale was revised for further psychometric evaluation. A sample (n = 399) of participants completed the LMHB scale. Confirmatory factor analysis was used to assess construct validity. Face validity was assessed using qualitative feedback. Reliability was assessed using Cronbach's alpha. The final model included five latent dimensions and one observed to represent each of the distinct pillars in lifestyle medicine. The open-ended response item elicited preponderance of positive feedback (∼80%); the scale was perceived as easy to understand and complete. Overall, the scale was reliable (α = 0.84). The LMHB scale assesses health behaviors across all six lifestyle medicine pillars, addressing each one systematically and individually. The scale had sufficient validity and reliability to measure health behaviors in this sample of adults. This is the first lifestyle medicine survey instrument to evaluate content, face, and construct validity and reliability.
本研究的目的是开发并验证一个量表，以衡量生活方式医学六大支柱领域的健康行为：睡眠、社交联系、体育活动、营养、物质使用和压力管理。一项预试验研究（n = 94）调查了生活方式医学健康行为（LMHB）量表的结构效度、收敛效度、内容效度和信度。基于预试验研究结果和文献，对该量表进行了修订，以进行进一步的心理测量学评估。一个由399名参与者组成的样本完成了LMHB量表。采用验证性因素分析来评估结构效度。通过定性反馈评估表面效度。使用克朗巴哈系数评估信度。最终模型包括五个潜在维度和一个观测变量，以代表生活方式医学中每个不同的支柱领域。开放式回答项得到了大量积极反馈（约80%）；该量表被认为易于理解和填写。总体而言，该量表具有信度（α = 0.84）。LMHB量表评估了生活方式医学所有六大支柱领域的健康行为，对每个领域进行了系统且单独的评估。该量表在测量这个成年样本的健康行为方面具有足够的效度和信度。这是首个评估内容效度、表面效度、结构效度和信度的生活方式医学调查工具。
