Abstract

Stigma is common in people with chronic pain. At present, however, the measurement of stigma in Spanish-speaking individuals remains a challenge due to a lack of validated measures in Spanish. The present study examines the psychometric properties of the Spanish version of the Stigma Scale for Chronic Illnesses 8-item version (SSCI-8) in people with chronic pain, focusing on dimensionality, factorial invariance, reliability (internal consistency and test-retest), and construct validity. Adults with chronic pain in Spain were recruited from patient associations and social networks to complete an online survey. The final sample comprised 530 individuals aged 18–70, predominantly women (> 90%). Half of the sample completed the SSCI-8 on a second occasion four weeks later. Data analyses supported a one-factor model with correlated errors as the most optimal solution for the SSCI-8 (CFI =.988; TLI =.983; WRMR =.938; RMSEA =.093; 95% CI [.076,.110]) and factorial invariance across different subgroups. SSCI-8 scores showed a normal distribution, good internal consistency, and adequate stability over time. Significant positive correlations were found, as expected, between stigma and depression, anxiety, pain intensity, pain interference, disability, and injustice experiences. Likewise, significant negative correlations were observed with psychological flexibility. The SSCI-8 accounted for incremental variance beyond injustice experiences in predicting the clinical outcomes. The Spanish version of the SSCI-8 appears psychometrically sound as a measure of stigma for use in people with chronic pain.

Perspective

The full invariance evidence across gender and pain type reported means that total score differences are due to real differences in perceived stigma, rather than observed differences in interpretations of item contents between men and women in pain or with different types of pain.

用8项慢性疾病病耻感量表（SSCI-8）评估西班牙慢性疼痛患者的病耻感

耻辱感在慢性疼痛患者中很常见。然而，由于缺乏有效的西班牙语测量方法，目前西班牙语个体的耻辱感测量仍然是一个挑战。本研究考察了西班牙版《慢性疾病病耻感量表》8项版本（ssi -8）在慢性疼痛患者中的心理测量特性，重点关注维度、因子不变性、信度（内部一致性和重测）和结构效度。在西班牙，研究人员从患者协会和社交网络中招募了患有慢性疼痛的成年人来完成一项在线调查。最终的样本包括530名年龄在18到70岁之间的人，主要是女性（约占90%）。一半的样本在四周后第二次完成了ssi -8。数据分析支持具有相关误差的单因素模型作为SSCI-8的最优解（CFI = 0.988; TLI = 0.983; WRMR = 0.938; RMSEA = 0.093; 95% CI[.076,]）。[110])和跨不同子群的阶乘不变性。ssi -8评分呈正态分布，内部一致性好，随时间变化具有足够的稳定性。正如预期的那样，耻辱感与抑郁、焦虑、疼痛强度、疼痛干扰、残疾和不公正经历之间存在显著的正相关。同样，心理灵活性也存在显著的负相关。ssi -8在预测临床结果时考虑了不公正经历之外的增量方差。西班牙语版的ssi -8在心理测量学上似乎是合理的，可以用来衡量慢性疼痛患者的耻辱感。观点：报告的性别和疼痛类型之间的完全不变性证据意味着总分差异是由于感知到的耻辱的实际差异，而不是观察到的疼痛或不同类型疼痛的男性和女性之间对项目内容的解释差异。

期刊介绍： The Journal of Pain publishes original articles related to all aspects of pain, including clinical and basic research, patient care, education, and health policy. Articles selected for publication in the Journal are most commonly reports of original clinical research or reports of original basic research. In addition, invited critical reviews, including meta analyses of drugs for pain management, invited commentaries on reviews, and exceptional case studies are published in the Journal. The mission of the Journal is to improve the care of patients in pain by providing a forum for clinical researchers, basic scientists, clinicians, and other health professionals to publish original research.
