观察评价法在人体工程学工作分析中经常使用，因为它比其他方法成本更低，耗时更短。ACGIH最近发布了重复工作的阈值限值（TLV）。该TLV建议使用Latko等人（1997）开发的一种这样的观察方法来评定手活动水平（HAL）和峰值力。对Latko方法的一个批评是，在分析过程中，评分者的可靠性和一致性是未知的。拉特科建议使用两名或更多训练有素的观察员来增加这种一致性。本研究分析了一家汽车装配厂的410个工作岗位，使用2名观察员记录了初始和最终评级。讨论前后计算了HAL和峰值力的加权kappa。在讨论之前，HAL的可靠性被评为中等，峰值力被评为一般。经过讨论，HAL和峰值力kappa值均被评为良好。
Observational rating methods are used frequently in ergonomic job analysis because they are less costly and time consuming than other methods. The ACGIH recently published a threshold limit value (TLV) for repetitive work. This TLV suggests the use of one such observational method developed by Latko et al. (1997) for rating Hand Activity Level (HAL) and peak force. One criticism of Latko's method is the unknown reliability and consistency of the raters during the analysis process. Latko suggests the use of two or more trained observers to increase this consistency. This study analyzed 410 jobs at an automotive assembly plant using 2 observers recording initial and final ratings. A weighted kappa was calculated for the HAL and peak force before and after discussion. Before discussion, HAL reliability was rated as moderate and peak force as fair. After discussion, both HAL and peak force kappa values were rated as good.
