The present research addressed the relation between catastrophizing, depression and response expectancies in anticipation of an experimental pain procedure. One hundred and twenty undergraduates (48 men, 72 women) participated in exchange for course credit. Prior to immersing one arm in a container of ice water, participants were asked to complete measures of catastrophizing and depression, and to estimate the degree of pain and emotional distress they expected to experience. After a 1-min immersion, participants rated their actual experience. Pain expectancies partially mediated the relation between catastrophizing and pain experience. Pain expectancies also mediated the relation between depression and pain experience. Catastrophizing, but not depression, was associated with a tendency to underestimate pain and emotional distress. The implications of these findings for the conceptual distinctiveness of catastrophizing and depression are discussed. Discussion also examines the potential implications of the present findings for pain management interventions.
本研究探讨了在预期进行实验性疼痛程序时，灾难化思维、抑郁与反应预期之间的关系。120名本科生（48名男性，72名女性）参与研究以换取课程学分。在将一只手臂浸入冰水容器之前，参与者被要求完成灾难化思维和抑郁程度的测量，并估计他们预期会经历的疼痛程度和情绪困扰程度。在浸入1分钟后，参与者对他们的实际体验进行评分。疼痛预期部分介导了灾难化思维与疼痛体验之间的关系。疼痛预期也介导了抑郁与疼痛体验之间的关系。灾难化思维而非抑郁，与低估疼痛和情绪困扰的倾向有关。讨论了这些发现对于灾难化思维和抑郁概念独特性的意义。讨论还考察了本研究结果对疼痛管理干预措施的潜在意义。
