Abstract

Abstract: 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, χ 2 (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. 簡體及繁體中文撮要由亞洲創傷心理研究學會翻譯: JOTS‐20‐0248.R2_Mekawi_Cantonese Traditional Chinese 創傷後迴避行為問卷在黑人女性創傷暴露樣本中的表現如何？ :一項驗證性研究 摘要: 在創傷性事件發生後, 參與創傷後迴避行為與創傷後壓力症(PTSD)的結果有關。鑑於在通常管理的創傷後壓力症症狀測量中使用的創傷後迴避的兩個項目評估的範圍存在固有的侷限性, 開發了25個項目的創傷後迴避行為問卷(PABQ)來評估一系列的迴避行為, 包括對視覺和感覺提醒的迴避、與創傷有關的想法和恐高症, 以及與家庭、睡眠和社會互動有關的迴避。然而, PABQ的效用因其缺乏(a)建構效度和(b)在不同樣本中的驗證而受到限制。為了解決這些局限性, 我們在暴露於創傷的黑人婦女(N=601, M年齡=41歲)的樣本中檢查了PABQ分數的心理測量特性。確認性因素分析表明, 當項目8被排除後, 原來的七因素模型很適合數據, χ2(231, N=602)=497.86, RMSEA=0.04, 90%CI[0.04, 0.05], CFI=0.99, TLI=0.989, WRMR=0.939, 但可靠性估計是可變的(即Cronbach的αs=0.70‐0.91)。此外, 我們發現收斂效度、臨床效度和增量效度得到支持。這些結果為PABQ在少數民族樣本中的心理測量優勢提供了證據, 並表明它是對黑人婦女創傷後迴避的有效評估。 Simplified Chinese 创伤后回避行为问卷在黑人女性创伤暴露样本中的表现如何？ :一项验证性研究 摘要: 在创伤性事件发生后, 参与创伤后回避行为与创伤后压力症(PTSD)的结果有关。鉴于在通常管理的创伤后压力症症状测量中使用的创伤后回避的两个项目评估的范围存在固有的局限性, 开发了25个项目的创伤后回避行为问卷(PABQ)来评估一系列的回避行为, 包括对视觉和感觉提醒的回避、与创伤有关的想法和恐高症, 以及与家庭、睡眠和社会互动有关的回避。然而, PABQ的效用因其缺乏(a)建构效度和(b)在不同样本中的验证而受到限制。为了解决这些局限性, 我们在暴露于创伤的黑人妇女(N=601, M年龄=41岁)的样本中检查了PABQ分数的心理测量特性。确认性因素分析表明, 当项目8被排除后, 原来的七因素模型很适合数据, χ2(231, N=602)=497.86, RMSEA=0.04, 90%CI[0.04, 0.05], CFI=0.99, TLI=0.989, WRMR=0.939, 但可靠性估计是可变的(即Cronbach的αs=0.70‐0.91)。此外, 我们发现收敛效度、临床效度和增量效度得到支持。这些结果为PABQ在少数民族样本中的心理测量优势提供了证据, 并表明它是对黑人妇女创伤后回避的有效评估。
