解释PTSD的种族差异是基于证明差异不是由于测量偏差。当评估中使用多种语言时，这是困难的。本研究采用验证性因素分析，以探讨可能的困难项目功能（DIF）在英语和西班牙语版本的创伤后应激障碍检查表平民版（PCL-C）。数据来自两个评估的西班牙裔（N = 304，213），谁是住院的身体伤害。校正多重检验后，单变量检验显示无统计学显著性DIF效应;多变量检验仅在初始评估时显示DIF的一些迹象。该偏倚在各波之间不一致，不太可能产生实质性后果，表明两个版本的PCL-C基本等同。
Interpretation of ethnic differences in PTSD is predicated on demonstration that differences are not due to measurement bias. This is difficult when multiple languages are used in the assessment. This study used confirmatory factor analysis to examine possible diffrential item functioning (DIF) across English and Spanish versions of the PTSD Checklist-Civilian Version (PCL-C). Data were derived from two assessments of Hispanics (Ns = 304, 213), who were hospitalized with physical injuries. After correction for multiple testing, univariate tests revealed no statistically significant DIF effects; multivariate tests revealed some indication of DIF at the initial assessment only. This bias was inconsistent across waves and unlikely to be substantively consequential, indicating that the two versions of the PCL-C were generally equivalent.
