戴维森创伤量表（DTS-C）中文版是为了满足华语人士的需求而开发的。 DTS 是一种经过验证的自评量表，用于诊断创伤后应激障碍 (PTSD)。 DTS-C是通过两阶段翻译从DTS翻译而来的。受试者是从 1999 年 9 月 21 日集集地震的 210 名幸存者中抽取的。该量表显示出良好的内部一致性（Cronbach's alpha = 0.97）和重测信度（r = 0.88）。临床诊断访谈获得了同步有效性，DTS-C 评分为 44 时诊断准确率为 0.85。结果表明，敏感性为 0.9，特异性为 0.81，阳性似然比为 4.74，阴性似然比为 0.12。对于分数范围 0-39，推荐的特定层似然比为 0.10（95% CI：0.05-0.20）；对于分数范围 40-59，推荐的特定层似然比为 4（2.22-7.23）；对于分数高于 60 的推荐的特定层似然比为 6.14（3.42-11.02）。在 PTSD 诊断受试者中，因子结构与 DSM-IV 分组非常相似创伤后应激障碍症状。 DTS-C 的心理测量强度对于其未来的使用是可靠的，特别是对于筛选可能诊断为 PTSD 的受试者。
The Chinese version of the Davidson Trauma Scale (DTS-C) was developed to respond to the need of Chinese-speaking individuals. The DTS is a validated self-rating scale used in the diagnosis of posttraumatic stress disorder (PTSD). The DTS-C is translated from DTS through a two-stage translation. Subjects were drawn from a sample of 210 survivors of the 21 September 1999, Chi-Chi Earthquake. The scale showed good internal consistency (Cronbach's alpha = 0.97) and test-retest reliability (r = 0.88). Concurrent validity was obtained against the clinical diagnostic interview, with a diagnostic accuracy of 0.85 at DTS-C score of 44. It showed that the sensitivity was 0.9, specificity 0.81, positive likelihood ratio 4.74, and negative likelihood ratio 0.12. The recommended stratum-specific likelihood ratios were 0.10 (95% CI: 0.05-0.20) for the score range 0-39, 4 (2.22-7.23) for the score range of 40-59, and 6.14 (3.42-11.02) for the scores above 60. In PTSD diagnosed subjects, the factor structures closely resembled the DSM-IV grouping of PTSD symptoms. The psychometric strength of DTS-C is reliable for its future use, particularly for screening for subjects with possible diagnosis of PTSD.
