Abstract

The Child PTSD Symptom Scale (Foa, Johnson, Feeny, & Treadwell, 2001) is a self-report measure of posttraumatic stress disorder symptoms (PTSD) in children and adolescents. Despite widespread use of this measure, no study to our knowledge has examined its psychometric properties in Latino children. This study examined the factor structure, internal consistency, and convergent validity of the measure utilizing a sample of 161 Latino students (M = 11.42 years, SD = 0.70) at high risk of exposure to community violence. Confirmatory factor analyses suggested that a 3-factor model consistent with the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) provided the best fit to the data. Internal consistency of the total scale and subscales was high when completed in English or Spanish. All Child PTSD Symptom Scale scores were positively correlated with violence exposure. As additional evidence of convergent validity, scores evidenced stronger correlations with internalizing symptoms than with externalizing symptoms. Results supported the use of the Child PTSD Symptom Scale as a measure of PTSD severity in Latino children, but additional research is needed to determine appropriate clinical cutoffs for Latino youths exposed to chronic levels of violence. Implications for clinical practice and future research are discussed.

標題:在拉丁裔兒童中兒童PTSD症狀量表的心理測量學特性。

撮要:兒童PTSD症狀量表(Foa et al., 2001)是在兒童青少年中使用的創傷後壓力症 (PTSD) 自我報告量表。儘管廣泛使用,但沒有研究關於在拉丁裔兒童中應用的心理測量學特性。本文採用住在高度社區暴力地區的161名拉丁裔學童(M=11.42年, SD=0.70) 為樣本,研究量表的因子結構、內在一致性和內聚效度。

驗證因子分析指出數據吻合一個符合精神病診斷和統計手冊(第四版)的3-因子模型。總量表和子量表在英語和西班牙語版本均有上佳的內在一致性。所有兒童PTSD症狀量表的分數都和暴力經歷呈正相連。PTSD 得分與內化症狀的關係,比較與外化症狀有着更強關係,從而確認本量表的內聚效度。結果支持本量表在拉丁裔兒童中能量度PTSD嚴重情況,但我們需要更多研究來決定在經歷長期暴力的拉丁裔青少年中什麼才是臨床合適的分界點。本文亦討論臨床服務和未來研究的影響。
