This study examined psychometric properties of the Pain Anxiety Symptoms Scale (PASS), a measure of pain-related fear. A recently developed shortened version of the PASS, the PASS-20, was also investigated. Previously reported factor structures of the PASS were tested by means of confirmatory factor analysis. Results indicated that all models fitted adequately but that a five-factor solution fitted slightly better compared to the other models tested. The four-factor solution of the PASS-20 was tested by means of confirmatory factor analysis and results indicated adequate fit. Moreover, the four-factor solution of the PASS-20 was invariant among fibromyalgia and low-back pain patients. Convergent validity of the original PASS and the PASS-20 was good and internal consistency reliability adequate to excellent. The suitability of the original PASS and the PASS-20 are discussed and directions for future research are provided.
本研究考察了疼痛焦虑症状量表（PASS）的心理测量学特性，该量表用于测量与疼痛相关的恐惧。同时还对最近开发的PASS简化版PASS - 20进行了研究。通过验证性因素分析对先前报道的PASS因素结构进行了检验。结果表明，所有模型拟合良好，但与其他测试模型相比，五因素模型的拟合效果略好。通过验证性因素分析对PASS - 20的四因素模型进行了检验，结果表明拟合良好。此外，PASS - 20的四因素模型在纤维肌痛患者和腰痛患者中具有不变性。原始PASS和PASS - 20的收敛效度良好，内部一致性信度从足够到优秀。文中讨论了原始PASS和PASS - 20的适用性，并提供了未来研究的方向。
