摘要
目的编制解离特质量表并检验其信效度。方法根据文献和心理测量学原理编制解离特质量表,对1306名大学生进行测试,并测试症状自评量表(SCL-90)作为效标。结果①探索性因子分析得到8个因子,分别为出神、现实解体、躯体化、人格解体、自我调节、情感麻木、疏忽遗忘、时空混乱,可解释总方差的57.69%。②总量表和8个因子分量表的Cronbach’α系数分别为0.969,0.889,0.907,0.874,0.890,0.892,0.872,0.855,0.830,重测信度分别为0.763,0.585,0.677,0.613,0.651,0.684,0.621,0.575,0.638(P〈0.01)。③解离特质量表总分和各因子分数分别与SCL-90总分和各因子分数呈正相关(r=0.200~0.714,P〈0.01)。结论解离特质量表在大学生中具有良好的信效度,可作为评估解离特质水平的测量工具。
Objective To develop the Dissociative Trait Scale(DTS) ,and examine its reliability and validity. Methods Based on literature and research work,a preliminary questionnaire was designed to measure dissociative trait. 1306 college students completed the DTS and Symptom Checklist 90(SCL-90). Results Explorarmy factor analysis extracted eight factors. The percentage of variance explained was 57.69%. The Cronbach α- coefficient of the total scale and the eight subscales ranged from 0. 830 - 0. 969,/he test-retest reliability ranged from 0. 575 - 763 (P〈 0.01 ). The seores of DTS significantly positively correlated with the scores of SCL-90 (P 〈 0.01 ). Conclusion The DTS has acceptable psychometric quality,and can be applied to assess dissociative traits in Chinese college students.
