目的：这项工作的目的是量化一组规模，评估重复，姿势和力量，在现场使用时，检查工业工作的评分员间的可靠性。背景资料：观察性评估方法的评估者间可靠性可能因方法的定义和使用情况而异。方法：在几个行业，846个工作进行了评估，使用对分析师率的重复，力量和姿势的上肢。12名经验水平不同的分析员参加了会议。结果如下：使用组间相关系数（ICC），力量和重复的可靠性值分别为0.60和0.71之前和0.82和0.87之后的讨论。经过讨论，最高姿势评分的ICC为0.60至0.83。平均姿势评分的ICC从最初的.31到.51，到最终的.55到.67。经验不足的分析师比资深调查员更容易改变他们的初始评级。结论：重复性和强制性指标的高评分者间可靠性表明，单个分析师适合进行基本工作评估。两名分析师的评级体系对股票评级有很大好处。平均姿势应在整个量表范围内进行评估，以进行评分者间可靠性评估。分析师对应轮换，以避免形成偏见。适用范围：对于用力和重复运动的基本评估，可以使用单个分析师，减少行业和大型流行病学研究的资源需求。
Objective: The aim of this work was to quantify the interrater reliability of a set of scales that assess repetition, posture, and force as used on site when examining industrial work. Background: Interrater reliability of observational assessment methods can vary depending on the definition of the methods and situations in which they are used. Method: In several industries, 846 jobs were assessed using pairs of analysts to rate the repetition, force, and posture of the upper limbs. Twelve analysts with varying experience levels participated. Results: Using an interclass correlation coefficient (ICC), force and repetition had reliability values of .60 and .71 before and .82 and .87 after discussion, respectively. After discussion, peak posture ratings had ICCs of .60 to .83. ICCs for average posture ratings ranged from .31 to .51 initially to .55 to .67 in final ratings. Less experienced analysts changed their initial ratings more than did the senior investigators. Conclusion: The high interrater reliability of the repetition and force metrics indicates that a single analyst is appropriate for basic job assessment. Posture ratings benefit greatly from a two-analyst system. Average postures should be assessed across a full range of the scale for interrater reliability assessment. Analyst pairs should be rotated to avoid forming biases. Application: For basic assessments of forceful exertions and repetitive motions, a single analyst can be used, reducing the resource requirements for both industry and large epidemiological studies.
