兒童創傷事件反應量表中文版信效度之建立

Psychometric Properties of the Chinese Version of the Child’s Reaction to Traumatic Events Scale

研究目的：國內目前用來評估兒童創傷後壓力疾患症狀之量表仍顯不足。本研究目的為中文化「兒童創傷事件反應量表」原始及修訂版本，並檢驗其信效度。研究方法：79名學齡兒童及其父母參與本研究。在篩選階段，藉由對兒童之父母進行半結構式會談，來評估兒童所經驗最嚴重之壓力事件，及此事件所引發之創傷後壓力疾患症狀。若此事件發生在一個月前，兒童及其父母則繼續參與後續評估。在評估階段，藉由對兒童進行半結構式會談及讓其填寫本研究中文化量表，父母填寫另一量表，來評估兒童創傷後壓力疾患症狀或診斷。研究結果：中文化後兩版本皆具良好內部一致性、適當聚合效度及滿意之效標效度，但相較修訂版在支持其基本三因子理論建構上，原始版本較支持其基本二因子理論建構。研究結論：整體而言，此量表之原始與其修訂版信效度類似，但建構效度上以原始版本為佳。目前當研究仍需檢驗修訂版之信效度之際，若欲評估台灣兒童創傷後壓力疾患症狀，特別在臨床使用上，建議以原始版本為佳。

Purpose: Currently, only a few measures are available to assess PTSD symptoms in Taiwanese children. The purpose of the study was to translate the Child’s Reaction to Traumatic Events Scale (CRTES) and its revised version, the CRTES-R, into Chinese (CCRTES and CCRTES-R) and to examine the psychometric properties of the Chinese translations. Methods: Seventy-nine Taiwanese children between 6 and 12 years old (mean age=9.48) and their parents participated in the study. In the screening phase, a semi-structured interview was conducted with the parents to determine the most stressful/traumatizing event to which the child had been exposed and the posttraumatic stress symptoms resulting from exposure to the event. If the children had experienced a stressful/traumatic event at least one month prior to the interview, they were enrolled in the assessment phase of the study. A semi-structured interview and the CCRTES/ CCRTES-R completed by the child and a parent-report measure were used to assess the child’s PTSD/PTSD symptoms. Results: The CCRTES and CCRTES-R have good internal consistency, adequate convergent validity, and satisfactory criterion validity. When compared to the CCRTES-R, the CCRTES fit the hypothesized two factor structure better than the CCRTES-R fit its hypothesized three factor structure. Conclusions: In general, the psychometric properties of the CCRTES are similar to those of the CCRTES-R; however, the construct validity of the CCRTES was better than that of the CCRTES-R. Thus, the CCRTES should be the preferred method of assessing posttraumatic stress symptoms in Taiwanese children, particularly in clinical settings, while researchers continue to examine the use of the CCRTES-R.
