Abstract: 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 Exploratory 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, the test-retest reliability ranged from 0.575 ～ 763 (P ＜ 0.01 ). The scores 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.
