目的：愤怒抑制或压抑与慢性疼痛严重程度之间联系的证据主要基于相关设计的研究。根据讽刺过程理论，我们提出，在挑衅过程中试图抑制愤怒的想法会增加慢性下腰痛(CLBP)患者随后的疼痛强度，而且这是通过矛盾地增强愤怒的可及性来实现的。设计：CLBP患者(N=58)被分配到抑制和非抑制条件下，同时与骚扰的同盟者一起执行计算机迷宫任务。随后进行了结构化疼痛行为任务(SPBT)。主要观察指标：迷宫任务后自评愤怒、焦虑、悲伤。在SPBT期间自我报告疼痛严重程度和观察到的疼痛行为数量。结果：被告知在刺激过程中抑制的患者：(A)在迷宫任务后报告了更大的愤怒，在SPBT过程中报告了更大的疼痛强度，并表现出比不抑制的患者更多的疼痛行为；(B)迷宫后的愤怒水平显著地中介了疼痛行为的群体差异。结论：具有讽刺意味的是，CLBP患者压制愤怒的尝试可能会通过愤怒情绪的增加而加剧与其临床状况相关的疼痛。
Objective: Evidence for links between anger inhibition or suppression and chronic pain severity is based mostly on studies with correlation designs. Following from ironic process theory, we proposed that attempts to suppress angry thoughts during provocation would increase subsequent pain intensity among chronic low back pain (CLBP) patients, and do so through paradoxically enhanced accessibility of anger. Design: CLBP patients (N = 58) were assigned to suppression and nonsuppression conditions while performing a computer maze task with a harassing confederate. A structured pain behavior task (SPBT) followed. Main outcome measures: Self-reported anger, anxiety, and sadness following maze task. Self-reported pain severity and number of observed pain behaviors during SPBT. Results: Patients told to suppress during provocation: (a) reported greater anger following the maze task, reported greater pain intensity during the SPBT, and exhibited more pain behaviors than patients not suppressing; (b) postmaze anger levels significantly mediated group differences on pain behaviors. Conclusion: Attempts by CLBP patients to suppress anger may aggravate pain related to their clinical condition through ironically increased feelings of anger.
