编制商业建筑工人疲劳评定量表，并检验其信度和效度。使用两个阶段的方法，我们首先确定了项目的发展疲劳评估量表的建筑工人（FASCW）通过审查现有的尺度在科学文献中，关键的线人访谈（n=11）和焦点小组（3组6名工人）与建筑工人。第二阶段包括评估的可靠性，有效性和敏感性的新量表使用重复测量的研究设计，方便的建筑工人样本（n=144）。第一阶段产生了一个16项的初步量表，经过因素分析产生了一个最终的10项量表，其中包括两个分量表（“嗜睡”和“身体不适”）。在第二阶段，FASCW及其分量表表现出令人满意的内部一致性（α系数为FASCW（0.91），嗜睡（0.86）和身体不适（0.84））和可接受的重测信度（皮尔逊相关系数：0.59-0.68;组内相关系数：0.74-0.80）。相关分析证实了同时效度和聚合效度。判别分析表明，FASCW区分关节炎状态和不同的工作时间组。FASCW 10项量表具有较好的信度和效度，是评价建筑工人疲劳程度的有效工具。
To develop a fatigue assessment scale and test its reliability and validity for commercial construction workers. Using a two-phased approach, we first identified items for the development of a Fatigue Assessment Scale for Construction Workers (FASCW) through review of existing scales in the scientific literature, key informant interviews (n=11) and focus groups (3 groups with 6 workers each) with construction workers. The second phase included assessment for the reliability, validity and sensitivity of the new scale using a repeated-measures study design with a convenience sample of construction workers (n=144). Phase one resulted in a 16-item preliminary scale that after factor analysis yielded a final 10-item scale with two sub-scales (“Lethargy” and “Bodily Ailment”).. During phase two, the FASCW and its subscales demonstrated satisfactory internal consistency (alpha coefficients were FASCW (0.91), Lethargy (0.86) and Bodily Ailment (0.84)) and acceptable test-retest reliability (Pearson Correlations Coefficients: 0.59–0.68; Intraclass Correlation Coefficients: 0.74–0.80). Correlation analysis substantiated concurrent and convergent validity. A discriminant analysis demonstrated that the FASCW differentiated between groups with arthritis status and different work hours. The 10-item FASCW with good reliability and validity is an effective tool for assessing the severity of fatigue among construction workers.
