疼痛焦虑症状量表-20(PASS-20)评估了疼痛相关焦虑的4个不同因素(即认知、恐惧、逃避/回避、生理)。PASS-20在临床样本中具有良好的因子稳定性、信度和内部一致性。非临床人群的心理测量数据尚未建立。本研究有四个目的：(1)使用非临床样本评估PASS-20的因素结构；(2)评估PASS-20子量表与相关自我报告工具的同时效度；(3)使用临床疼痛样本将我们的结果与类似研究的结果进行比较；以及(4)提出一个初步的分界值来识别显著升高的疼痛相关焦虑。作为更大研究的一部分，155名本科生完成了PASS-20考试。验证性因素分析支持现有的四因素模型，总分和分量表得分的内部一致性与以前的研究相当。PASS-20总分和分量表得分与其他相关测量呈中度相关，提供了同时效度的证据。在PASS-20的所有子量表上，非临床样本的得分显著低于临床疼痛样本(P<；0.01)。被归类为高度疼痛相关焦虑的大多数人的及格总分超过30分。展望：本研究使用非临床样本来探讨PASS-20的心理测量学特性。验证性因素分析，与临床疼痛样本的比较，以及表明高水平疼痛相关焦虑的初步截止分数被讨论，疼痛相关焦虑被确定为一个连续的结构，在临床和非临床样本中都是健壮的。(C)2007年，由美国疼痛协会提供。
The Pain Anxiety Symptoms Scale-20 (PASS-20) assesses 4 factorially distinct components of pain-related anxiety (ie, cognitive, fear, escape/avoidance, physiological). The PASS-20 has good factor stability, reliability, and internal consistency in clinical samples. Psychometric data for nonclinical populations are not yet established. This study had 4 purposes: (1) To assess the factor structure of the PASS-20 with a nonclinical sample; (2) to assess concurrent validity of PASS-20 subscales with related self-report instruments; (3) to compare our results with findings of a similar study using a clinical pain sample; and (4) to suggest a preliminary cut-off score to identify individuals with significantly elevated pain-related anxiety. A sample of 155 undergraduates completed the PASS-20 as part of a larger study. Confirmatory factor analysis supported the existing 4-factor model, and internal consistencies for total and subscale scores were comparable with previous research. PASS-20 total and subscale scores were moderately correlated with other related measures, providing evidence of concurrent validity. On all PASS-20 subscales the nonclinical sample had significantly lower (P < .01) scores than those for a clinical pain sample. The majority of individuals classified as having high pain-related anxiety had PASS-20 total scores greater than 30. implications and future research directions are discussed.Perspective: A nonclinical sample is used to explore the psychometric properties of the PASS-20. Confirmatory factor analysis, comparisons with a clinical pain sample, and preliminary cut-off scores indicative of high levels of pain-related anxiety are discussed Pain-related anxiety is identified as a continuous construct, robust across both clinical and nonclinical samples.
