摘　　要：目的 对工作适应障碍量表（Work Attitude Scale,Wa）进行项目分析并研制简式量表.方法 对3767名新兵同时进行Wa和症状自评量表（SCL-90）测试,对Wa进行项目分析并筛选出部分条目组成简式量表.计算原量表及简式量表的Cronbach＇ sα系数,并考察原量表及简式量表的效标效度.对于其他样本,分别用16PF、EPQ、SAS等与简式量表同时施测,以16PF、EPQ、SAS等为效标,考察简式量表的效标效度.结果 原最表各项目的难度在0.03～0.87之间,小于0.2或大于0.8的项目有27个.鉴别度指数在0.04 ～0.56之间,小于0.3的项目有22个.各项目分与Wa总分的相关系数在0.02～0.52之间,小于0.3的项目有18个.原量表和简式量表的Cronbach＇s α系数分别为0.778和0.789.原量表总分及简式量表总分与SCL-90总分及各因子分均显著正相关,相关系数均在0.40以上.简式量表总分与原量表总分显著相关,相关系数为0.934.简式量表总分与16PF、EPQ、SAS等显著相关.结论 简式量表具有较好的信度和效度.Objective To conduct item analysis on Work Attitude Scale（Wa） and to develop a short-versioned scale.Methods Wa and Symptom Checklist 90（SCL-90） were administered to 3767 recruits,item analysis of Wa was conducted and short version of Wa was developed based on the results of item analysis,Cronbach＇ s αcoefficient of the original scale and the short-versioned scale was calculated,criterion validity of the original scale and the short-versioned scale was analyzed using SCL-90 as the validity criterion.For other samples,16 Personality Factor Questionnaire （16PF）,Eysenck Personality Questionnaire （ EPQ）,and Self-Rating Anxiety Scale （SAS） were tested while the short-versioned scale was tested at the same time,criterion validity of the short-versioned Wa was analyzed using 16PF,EPQ,and SAS as the validity criterion.Results Difficulty of the original scale was from 0.03 to 0.87,27 items＇ difficulty was less than 0.20 or greater than.Discrimination index was from 0.04 to 0.56,22 items＇ discrimination index was less than 0.30.Correlation coefficient of the item score and the total score is from 0.02 to 0.52,18 items＇ correlation coefficient was less than 0.30.The short-versioned scale was made up of the 18 items with better quality.Cronbach＇ s α coefficient of the original scale and the short-versioned scale was 0.778 and 0.789,respectively.Both the total score of the original scale and the short-versioned scale were significantly correlated with the scores of SCL-90,and all the correlation coefficient were above 0.40.The correlation coefficient between the score of the short-versioned scale and that of the original scale was 0.934.The correlation coefficient between the score of the short-versioned scale and 16PF,EPQ,SAS was significant.Conclusion The short-versioned scale has a higher reliability and good validity.
