BACKGROUND & AIMS:
:Chronic pain is a potentially stigmatizing condition. However, stigma has received limited empirical investigation in people with chronic pain. Therefore, we examined the psychometric properties of a self-report questionnaire of stigma in people with chronic pain attending interdisciplinary treatment. Secondarily, we undertook an exploratory examination of the magnitude of change in stigma associated with interdisciplinary treatment in a prospective observational cohort. Participants attending interdisciplinary treatment based on acceptance and commitment therapy completed the Stigma Scale for Chronic Illness 8-item version (SSCI-8; previously developed and validated in neurological samples), and measures of perceived injustice, pain acceptance, and standard pain outcomes before (n = 300) and after treatment (n = 247). A unidimensional factor structure and good internal consistency were found for the SSCI-8. Total SSCI-8 scores were correlated with pain intensity, indices of functioning, and depression in bivariate analyses. Stigma scores were uniquely associated with functioning and depression in multiple regression analyses controlling for demographic factors, pain intensity, pain acceptance, and perceived injustice at baseline. SSCI-8 total scores did not significantly improve after treatment, although an exploratory subscale analysis showed a small improvement on internalized stigma. In contrast, scores on perceived injustice, pain acceptance, and pain outcomes improved significantly. Taken together, these data support the reliability and validity of the SSCI-8 for use in samples with chronic pain. Further research is needed optimize interventions to target stigma at both the individual and societal levels. PERSPECTIVE: This study supports the use of the SSCI-8 to measure stigma in chronic pain. Stigma is uniquely associated with worse depression and pain-related disability. Research is needed to identify how to best target pain-related stigma from individual and societal perspectives.
背景与目标:
: 慢性疼痛是一种潜在的污名化疾病。然而,污名在慢性疼痛患者中接受的实证研究有限。因此,我们检查了参加跨学科治疗的慢性疼痛患者的耻辱感自我报告问卷的心理测量特性。其次,我们对前瞻性观察队列中与跨学科治疗相关的污名变化幅度进行了探索性检查。参加基于接受和承诺治疗的跨学科治疗的参与者完成了慢性病的污名量表8项版本 (SSCI-8; 以前在神经系统样本中开发和验证),以及感知的不公正,疼痛接受,治疗前 (n = 300) 和治疗后 (n = 247) 的标准疼痛结局。发现该SSCI-8具有一维因子结构和良好的内部一致性。在双变量分析中,总SSCI-8评分与疼痛强度,功能指数和抑郁相关。在控制人口统计学因素,疼痛强度,疼痛接受程度和基线感知不公正的多元回归分析中,污名得分与功能和抑郁唯一相关。SSCI-8总分在治疗后没有显著改善,尽管探索性子量表分析显示内在化污名有小幅改善。相比之下,感知到的不公正、疼痛接受和疼痛结果的得分显著提高。综上所述,这些数据支持用于慢性疼痛样本的SSCI-8的可靠性和有效性。需要进一步的研究优化干预措施,以针对个人和社会层面的污名。观点: 本研究支持使用该SSCI-8测量慢性疼痛的耻辱感。污名与更严重的抑郁和疼痛相关的残疾有着独特的联系。需要进行研究,以确定如何从个人和社会的角度最好地针对与疼痛相关的污名。
