Objectives The aim of this study was to evaluate the reliability and validity of the Chinese version of the Stigma Scale for Chronic Illness (SSCI) in patients with stroke. Methods In total, 220 patients with stroke were recruited to complete the scale. The reliability of the SSCI was evaluated using internal consistency and test-retest methods. Exploratory factor analysis (EFA) was conducted to identify domains of the SSCI. Convergent validity was determined by analyzing the correlation between SSCI scores, activities of daily living (ADL) and depression. Results Construct validity was determined by factor analysis, extracting three factors with eigenvalues greater than 1, explaining 30.5%, 25.7%, and 8.5% of the variance, respectively, and accounting for 64.8% of the variance. All items had factor loadings above 0.40. The first factor comprised questions related to 'self-stigma' (items 1-13). The second (items 14-22) and third (items 23-24) factors aggregated questions related to 'enacted stigma'. In terms of convergent validity, the SSCI total scale was moderately correlated to the Barthel Index (BI) and the Self-rating Depression Scale (SDS). Cronbach's alpha value (internal reliability) for the total SSCI score was 0.949, and the intraclass correlation coefficient value (test-retest reliability) was 0.802. Discussion The results provide initial evidence that the SSCI is a reliable and validated measure for evaluating stigma in stroke patients in China.
目的 本研究旨在评估中文版慢性病耻辱感量表（SSCI）在中风患者中的信度和效度。方法 共招募220例中风患者完成该量表。采用内部一致性和重测法评估SSCI的信度。进行探索性因素分析（EFA）以确定SSCI的维度。通过分析SSCI得分、日常生活活动能力（ADL）和抑郁之间的相关性来确定收敛效度。结果 通过因素分析确定结构效度，提取出三个特征值大于1的因素，分别解释了30.5%、25.7%和8.5%的方差，共占方差的64.8%。所有项目的因素负荷均高于0.40。第一个因素包括与“自我耻辱感”相关的问题（项目1 - 13）。第二个因素（项目14 - 22）和第三个因素（项目23 - 24）汇总了与“ enacted stigma”相关的问题。在收敛效度方面，SSCI总量表与巴氏指数（BI）和自评抑郁量表（SDS）呈中度相关。SSCI总分的Cronbach's alpha值（内部信度）为0.949，组内相关系数值（重测信度）为0.802。讨论 结果提供了初步证据，表明SSCI是评估中国中风患者耻辱感的可靠且经过验证的测量工具。
