目的：本研究旨在澄清疼痛相关的灾难化是否是一种反应，不同的情况下，一个特定的情境（状态）或持久的人格结构（trait）.Methods：我们进行了一项队列研究，150例患者接受全膝关节镜手术在2家医院。患者完成了一系列心理测量，提供了各种社会人口学数据，并随访6个月。我们假设，相关的全膝关节镜手术和恢复将预测未来catastrophizing severity.Results：控制基线协变量的年龄，性别，种族，抑郁症和焦虑后，我们发现，目前的疼痛感觉强度预测未来catastrophizing严重程度。疼痛强度的变化与基线至6个月postsurgery的catastrophizing的变化相关，但基线至2个月postsurgery.Discussion：这些数据提供了初步支持的概念，即疼痛相关的catastrophizing是一个动态的结构，与疼痛强度。
Objectives: This study sought to clarify whether pain-related catastrophizing is a response that varies given a specific situational circumstance (state) or an enduring personality construct (trait).Methods: We conducted a cohort study of 150 patients undergoing total knee arthroscopy at 2 hospitals. Patients completed a battery of psychological measures, provided various sociodemographic data, and were followed for 6 months. We hypothesized that associated total knee arthroscopy surgery and recovery would predict future catastrophizing severity.Results: After controlling for baseline covariates of age, sex, ethnicity, depression, and anxiety, we found that current pain sensation intensity predicted future catastrophizing severity. Change in pain intensity was associated with the change in catastrophizing for the baseline to 6 months postsurgery, but not between the baseline to 2 months postsurgery.Discussion: These data provide preliminary support for the notion that pain-related catastrophizing is a dynamic construct that is related to pain intensity.
