Engaging in posttraumatic avoidance behaviors after a traumatic incident is associated with posttraumatic stress disorder (PTSD) outcomes. Given the inherent limitations in the scope of the two-item assessment of posttraumatic avoidance used in commonly administered measures of PTSD symptoms, the 25-item Posttraumatic Avoidance Behaviour Questionnaire (PABQ) was developed to assess a range of avoidance behaviors, including avoidance of visual and sensory reminders, trauma-related thoughts, and agoraphobia, as well as avoidance related to the home, sleep, and social interaction. However, the PABQ's utility is limited by its lack of (a) construct validity and (b) validation in diverse samples. To address these limitations, we examined the psychometric properties of PABQ scores in a sample of trauma-exposed Black women (N = 601, M age = 41 years). Confirmatory factor analyses indicated that the original seven-factor model fit the data well when Item 8 was excluded, χ²(231, N = 602) = 497.86, RMSEA = .04, 90% CI [.04, .05], CFI = .99, TLI = .989, WRMR = .939, but reliability estimates were variable (i.e., Cronbach's αs = .70–.91). In addition, we found support for convergent validity, clinical validity, and incremental validity. These results provide evidence for the psychometric strengths of the PABQ in minority samples and suggest that it is a valid assessment of posttraumatic avoidance in Black women.

创伤后回避行为问卷在遭受创伤的黑人女性样本中的验证和构建有效性

在创伤事件后从事创伤后回避行为与创伤后应激障碍 (PTSD) 的结果有关。鉴于在通常管理的 PTSD 症状测量中使用的创伤后回避的两项评估范围的固有局限性，开发了 25 项创伤后回避行为问卷 (PABQ) 来评估一系列回避行为，包括回避视觉和感官提醒、与创伤相关的想法和广场恐惧症，以及与家庭、睡眠和社交互动相关的回避。然而，PABQ 的实用性受到其缺乏（a）结构有效性和（b）在不同样本中的验证的限制。为了解决这些限制，我们检查了暴露于创伤的黑人女性样本中 PABQ 分数的心理测量特性（N= 601，M年龄 = 41 岁）。验证性因子分析表明，当排除第 8 项时，原始七因子模型与数据拟合良好，χ ² (231, N = 602) = 497.86, RMSEA = .04, 90% CI [.04, .05], CFI = .99，TLI = .989，WRMR = .939，但可靠性估计是可变的（即，Cronbach 的 αs = .70–.91）。此外，我们发现了对收敛效度、临床效度和增量效度的支持。这些结果为少数群体样本中 PABQ 的心理测量强度提供了证据，并表明它是对黑人女性创伤后回避的有效评估。
