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).
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.
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.
These data provide preliminary support for the notion that pain-related catastrophizing is a dynamic construct that is related to pain intensity.
本研究旨在阐明疼痛相关的灾难化思维是一种特定情境下的反应（状态）还是一种持久的人格结构（特质）。
我们对在 2 家医院接受全膝关节镜手术的 150 名患者进行了队列研究。患者完成了一系列心理测量，提供了各种社会人口统计学数据，并随访了 6 个月。我们假设与全膝关节镜手术和康复相关的因素会预测未来灾难化思维的严重程度。
在控制了年龄、性别、种族、抑郁和焦虑等基线协变量后，我们发现当前的疼痛感觉强度预测了未来灾难化思维的严重程度。疼痛强度的变化与基线至术后 6 个月期间灾难化思维的变化相关，但与基线至术后 2 个月期间的变化无关。
这些数据初步支持了这样一种观点，即与疼痛相关的灾难化思维是一种与疼痛强度相关的动态结构。
