Pain behaviors that are maintained beyond the acute stage after injury can contribute to subsequent psychosocial and physical disability. Critical to the study of pain behaviors is the availability of psychometrically sound pain behavior measures. In this study we developed a self-report measure of pain behaviors, the Pain Behaviors Self Report (PaB-SR). PaB-SR scores were developed using item response theory and evaluated using a rigorous, multiple-witness approach to validity testing. Participants included 661 survey participants with chronic pain and with multiple sclerosis, back pain, or arthritis; 618 survey participants who were significant others of a chronic pain participant; and 86 participants in a videotaped pain behavior observation protocol. Scores on the PaB-SR were found to be measurement invariant with respect to clinical condition. PaB-SR scores, observer reports, and the videotaped protocol yielded distinct, but convergent views of pain behavior, supporting the validity of the new measure. The PaB-SR is expected to be of substantial utility to researchers wishing to explore the relationship between pain behaviors and constructs such as pain intensity, pain interference, and disability.
受伤后超过急性期仍持续存在的疼痛行为可能导致随后的心理社会和身体残疾。疼痛行为的研究关键在于是否有可靠的心理测量疼痛行为测量方法。在这项研究中，我们开发了一种疼痛行为的自我报告测量工具，即疼痛行为自我报告（PaB-SR）。PaB-SR 分数是使用项目反应理论开发的，并使用严格的、多证人的有效性测试方法进行评估。参与者包括 661 名患有慢性疼痛和多发性硬化症、背痛或关节炎的调查参与者；618 名慢性疼痛参与者的重要他人的调查参与者；以及 86 名参与录像疼痛行为观察方案的参与者。研究发现，PaB-SR 分数在临床状况方面具有不变的测量特性。PaB-SR 分数、观察者报告和录像方案得出了疼痛行为的不同但一致的观点，支持了新测量方法的有效性。预计 PaB-SR 将对希望探索疼痛行为与疼痛强度、疼痛干扰和残疾等结构之间关系的研究人员具有重要的实际应用价值。
