摘要
目的对普遍性适应不良量表（General Maladjustment Scale，Gm）进行项目分析并研制简式普遍性适应不良量表。方法对3767名新兵同时进行Gm和症状自评量表（SCL-90）测试，对Gm各项目进行难度和鉴别度分析，各项目分与Gm总分的相关分析，根据分析结果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’s α系数，以SCL-90各因子分为效标，考察原量表及简式量表的效标效度。结果原量表各项目的难度在0．03～0．72之间，小于0．2的项目有21个。鉴别度指数在-0．19～0．45之间，小于0．3的项目有21个。各项目分与Gm总分的相关系数在-0．17～0．48之间，小于0．3的项目有14个。保留质量较高的16个项目组成简式量表。原量表和简式量表的Cronbach’s α系数分别为0．713和0．700。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0．914。结论原量表及简式量表均具有较好的信度和效度。
Objective To conduct item analysis on General Maladjustment Scale （Gm） and to develop a short-versioned scale. Methods Gm and Symptom Checklist 90（SCL-90） were administered to 3767 recruits, difficulty and discrimination of each item of Gm were calculated, correlation between item score and total score was analyzed, short-versioned Gm was developed based on the results of item analysis, Cronbach＇ sot coefficient of the original scale and the short-versioned scale was calculated, criterion validity was analyzed using SCL-90 as the validity criterion. Results Difficulty of the original scale was from 0.03 to 0.72, 21 items＇ difficulty was less than 0.20. Discrimination index was front -0.19 to 0.45, 21 items＇ discrimination index was less than 0.30. Correlation coefficient of the item score and the total score is front - 0.17 to 0.48, 21 items＇ correlation coefficient was less than 0.30. The short-versioned scale was made up of the 16 items with better quality. Cronbach＇ s α coefficient of the original scale and the short-versioned scale was 0. 713 and 0. 700, 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. 914. Conclusion Both the original scale and the short-versioned scale have a higher reliability and good validity.
