This study tested a repeated-measures application of the Leading by Example (LBE) questionnaire, a self-report instrument measuring organizational leadership support for health promotion.
The efficacy of the LBE was tested in a quasi-experimental health promotion intervention trial. Twelve worksites were assigned to three intervention conditions (i.e., control, moderate, high intensity).
The worksites were selected from a large U.S.-based chemical company.
Baseline data were collected from employees in various job roles in 2005 (N = 125). Follow-up data were collected in 2006 (N = 114) and 2007 (N = 106). Response rates ranged from 54% to nearly three-fourths of potential respondents.
Worksites assigned to both treatment conditions received changes in the built environment via supports for weight management. Worksites assigned to the intense condition received additional elements designed to impact leadership's support for a positive health promotion climate.
Four LBE factors measuring management support for health were assessed over time.
The Kruskal-Wallis H-test and analyses of variance/covariance were used to compare LBE scores.
Significant changes from baseline to 2006 were identified for the four factors (p = .000) of the LBE. No significant changes were found from 2006 to 2007.
The LBE effectively captured perceptions of management support for health. Researchers and practitioners alike should consider using the LBE to track and evaluate perceptions of management support for health promotion.
本研究测试了一种对榜样引领（LBE）问卷的重复测量应用，这是一种自我报告工具，用于衡量组织对健康促进的领导力支持。
LBE 的功效在一项准实验性健康促进干预试验中进行了测试。12 个工作场所被分配到三种干预条件（即对照、中度、高强度）。
工作场所选自一家大型美国化学公司。
2005 年（N=125），从各种工作岗位的员工中收集基线数据。2006 年（N=114）和 2007 年（N=106）收集了随访数据。响应率从 54%到接近四分之三的潜在受访者。
分配给两种治疗条件的工作场所通过支持体重管理来改变建筑环境。被分配到强化条件的工作场所收到了旨在影响领导层对积极健康促进氛围的支持的其他元素。
在不同时间评估了四个衡量管理对健康支持的 LBE 因素。
使用 Kruskal-Wallis H 检验和方差分析/协方差分析来比较 LBE 评分。
LBE 的四个因素（管理对健康的支持）从基线到 2006 年有显著变化（p=0.000）。从 2006 年到 2007 年，没有发现显著变化。
LBE 有效地捕捉了对管理支持健康的看法。研究人员和实践者都应该考虑使用 LBE 来跟踪和评估对健康促进的管理支持的看法。
