The present study aimed at investigating whether chronic pain patients are impaired in Theory of Mind (ToM), or Emotional Awareness.
Thirty inpatients suffering from chronic somatoform pain, as well as thirty healthy controls matched for age, sex, and education were recruited. ToM abilities were measured using the Frith-Happé animation task, in which participants interpret video-clips depicting moving geometric forms that mimic social interactions. The responses given were scored for appropriateness and the degree of inferred intentionality according to established protocols. Emotional awareness was measured using the Levels of Emotional Awareness Scale (LEAS), for which participants provide written descriptions of feelings in imaginary emotional situations. Standardized scoring was performed to capture the number and quality of emotional terms used.
Responses lengths were similar in both groups and for both tasks. Patients attained significantly lower intentionality but not appropriateness scores when interpreting ToM interactions. No significant group differences were found when interpreting goal directed interactions. Emotional awareness scores were significantly lower in patients compared to healthy controls.
Our results suggest that chronic pain patients are impaired in mentalizing and emotional awareness. Future studies are needed to determine whether these ToM and emotional awareness deficits contribute to the etiology of somatoform pain and whether addressing these deficits in therapeutic interventions can improve polymodal pain therapy.
本研究旨在调查慢性疼痛患者在心理理论(ToM)或情绪意识方面是否存在缺陷。
招募了30名患有慢性躯体形式疼痛的住院患者以及30名年龄、性别和教育程度相匹配的健康对照者。使用弗里思-哈佩动画任务来测量心理理论能力,在该任务中,参与者解读描绘模仿社会互动的移动几何图形的视频片段。根据既定方案,对给出的反应在适当性和推断意图程度方面进行评分。使用情绪意识水平量表(LEAS)来测量情绪意识,参与者需针对想象中的情绪情境提供感受的书面描述。进行标准化评分以获取所使用情绪词汇的数量和质量。
两组在两项任务中的反应长度相似。在解读心理理论互动时,患者获得的意图得分显著较低,但适当性得分无显著差异。在解读目标导向互动时,未发现显著的组间差异。与健康对照者相比,患者的情绪意识得分显著较低。
我们的结果表明,慢性疼痛患者在心理化和情绪意识方面存在缺陷。未来需要开展研究,以确定这些心理理论和情绪意识缺陷是否导致躯体形式疼痛的病因,以及在治疗干预中解决这些缺陷是否能改善多模式疼痛治疗。
