This study tested the reliability and validity of industry- and mill-level expert methods for measuring psychosocial work conditions in British Columbia sawmills using the demand-control model.
In the industry-level method 4 sawmill job evaluators estimated psychosocial work conditions at a generic sawmill. In the mill-level method panels of experienced sawmill workers estimated psychosocial work conditions at 3 sawmills. Scores for psychosocial work conditions were developed using both expert methods and applied to job titles in a sawmill worker database containing self-reported health status and heart disease. The interrater reliability and the concurrent and predictive validity of the expert rater methods were assessed.
The interrater reliability and concurrent reliability were higher for the mill-level method than for the industry-level method. For all the psychosocial variables the reliability for the mill-level method was greater than 0.90. The predictive validity results were inconclusive.
The greater reliability and concurrent validity of the mill-level method indicates that panels of experienced workers should be considered as potential experts in future studies measuring psychosocial work conditions.
本研究使用需求控制模型，检验了不列颠哥伦比亚省锯木厂中行业层面和工厂层面专家方法在测量心理社会工作条件方面的可靠性和有效性。
在行业层面方法中，4名锯木厂工作评估员对一家通用锯木厂的心理社会工作条件进行了评估。在工厂层面方法中，由经验丰富的锯木厂工人组成的小组对3家锯木厂的心理社会工作条件进行了评估。心理社会工作条件得分通过这两种专家方法得出，并应用于一个包含自我报告健康状况和心脏病情况的锯木厂工人数据库中的职位。评估了专家评分方法的评分者间信度以及同时效度和预测效度。
工厂层面方法的评分者间信度和同时信度高于行业层面方法。对于所有心理社会变量，工厂层面方法的信度均大于0.90。预测效度结果尚无定论。
工厂层面方法更高的信度和同时效度表明，在未来测量心理社会工作条件的研究中，经验丰富的工人小组应被视为潜在的专家。
