The Pain Outcomes Profile (POP) is a brief, multidimensional measure intended to assess pain intensity, functioning, and affect. It is presented as a practical measure with clinical utility. Results of studies support its concurrent, construct and predictive validity at the scale level. However, there have been no published studies of the measure at the item level. The present study was intended to assess the construct validity of the POP by way of factor analysis. A sample of 447 assessments of patients at a chronic non-cancer pain outpatient treatment center was employed. The 20 substantive items comprising the POP were entered into a factor analysis with oblique rotation. Five salient factors were obtained. Item-inclusion was generally consistent with factor loadings although noteworthy exceptions were observed in the Fear, Mobility and Vitality scales. Recommendations for further study and limitations of the current project are delineated.
疼痛结果概况（POP）是一种简短的多维测量工具，旨在评估疼痛强度、功能和情感。它是一种具有临床实用性的实用测量工具。研究结果支持其在量表层面的同时效度、结构效度和预测效度。然而，目前尚无关于该测量工具项目层面的已发表研究。本研究旨在通过因子分析评估POP的结构效度。我们采用了一个慢性非癌性疼痛门诊治疗中心447例患者评估的样本。将构成POP的20个实质性项目进行斜交旋转的因子分析。得到了五个显著因子。项目纳入通常与因子载荷一致，尽管在恐惧、活动能力和活力量表中观察到了值得注意的例外情况。文中还阐述了进一步研究的建议和当前项目的局限性。
