Reliability and validity of the Work Assessment Scale (WAS) was done on a sample of 551 subjects with multiple sclerosis. Work was defined as those activities performed in employment, homemaking and/or personal care. The WAS has two parts consisting of: Work-Impeding (WAS-I) and Work Enhancing (WAS-E) situations and conditions. Varimax rotated factor analysis of the WAS-I resulted in a seven-factor solution containing 33 of the 53 scale items. Theta reliability coefficients for the factors ranged between .73 and .90 and test-retest correlation coefficients (n = 51) ranged between .76 and .91. Varimax rotated factor analysis of the WAS-E resulted in a five-factor solution containing 19 of the 27 scale items. Theta reliability coefficients for the factors ranged between .66 and .81 and test-retest correlation coefficients ranged between .68 and .82. Concurrent validity was shown between WAS and both ADL and Symptom subscales.
工作评估量表（WAS）的信效度在551名多发性硬化症患者样本中进行了研究。工作被定义为在就业、家务管理和/或个人护理中所进行的活动。WAS有两个部分，包括：工作阻碍（WAS-I）和工作促进（WAS-E）情况与条件。对WAS-I进行方差最大化旋转因子分析，得到一个七因子解，包含53个量表项目中的33个。各因子的西塔信度系数在0.73至0.90之间，重测相关系数（n = 51）在0.76至0.91之间。对WAS-E进行方差最大化旋转因子分析，得到一个五因子解，包含27个量表项目中的19个。各因子的西塔信度系数在0.66至0.81之间，重测相关系数在0.68至0.82之间。WAS与日常生活活动（ADL）及症状分量表之间均显示出同时效度。
