【目的】评价中医湿证评估量表 (DSSCM) 应用于特应性皮炎患者的适用性。 【方法】采用横断面调查法,采集204例特 应性皮炎患者的基本信息以及DSSCM、患者湿疹自我检查评分量表 (POEM) 、特应性皮炎控制工具 (ADCT) 、特应性皮炎积 分指数 (SCORAD) 、湿疹面积及严重程度指数 (EASI) 、研究者总体评估 (IGA) 量表的得分情况,使用SPSS、AMOS分析 DSSCM的信度和效度,探究湿证与特应性皮炎临床指标间的相关性。 【结果】量表总体克朗巴赫α系数 (Cronbach’ α系数) 为 0.90,Spearman-Brown分半信度系数为0.81,内容效度结果除外DSSCM 25、DSSCM 26、DSSCM 27、DSSCM 28、DSSCM 29 这5个条目的系数范围<0.30,其余各条目与维度以及维度与量表总分间的相关系数范围均大于0.40。集合效度、区分效 度实验成功率均大于80%,验证性因子分析中卡方自由度比 (χ2 /df) 、近似平均方根误差 (RMSEA) 达到良好标准。相关性分 析结果显示,DSSCM评分与体质量指数 (BMI) 、皮肤病生活质量指数 (DLQI) 得分、POEM得分、ADCT得分、瘙痒得分、睡 眠得分、SCORAD得分均显著相关 (P<0.05或P<0.01) ,与病程、年龄、IGA得分、EASI得分均无显著性相关 (P>0.05) 。 【结论】DSSCM应用于特应性皮炎患者具有良好的信度和效度,与特应性皮炎临床指标间具有相关性,适用于特应性皮炎患 者临床湿证评估。

Objective To evaluate the applicability of the Dampness Syndrome Scale of Chinese Medicine (DSSCM) in patients with atopic dermatitis (AD) . Methods A cross-sectional study was conducted 204 AD patients. Demographic data and scores of the DSSCM,Patient-Oriented Eczema Measure (POEM),Atopic Dermatitis Control Tool (ADCT),Scoring Atopic Dermatitis(SCORAD),Eczema Area and Severity Index (EASI),and Investigator’ s Global Assessment (IGA) were collected. SPSS and AMOS were used to analyze the reliability and validity of the DSSCM and then the correlation between dampness syndrome and clinical AD indicators was explored. Results The overall Cronbach’ s α coefficient of DSSCM was 0.90,and the Spearman-Brown split-half reliability coefficient was 0.81. Content validity results indicated that,except for items DSSCM 25,DSSCM 26, DSSCM 27, DSSCM 28, and DSSCM 29 (with correlation coefficients <0.30), all other items showed correlation coefficients >0.40 with their respective dimensions and the total scale score. The success rates of convergent and discriminant validity tests exceeded 80%,and confirmatory factor analysis demonstrated good fit in the indices of χ2 /df and RMSEA. Correlation analysis revealed that DSSCM scores were significantly correlated with body mass index (BMI) ,Dermatology Life Quality Index (DLQI) scores,POEM scores,ADCT scores,pruritus scores,sleep scores,or SCORAD scores (P<0.05 or P<0.01) . However,no significant correlations were observed between DSSCM scores and disease duration,age,IGA scores,or EASI scores (P>0.05) . Conclusion The DSSCM demonstrates good reliability and validity in AD patients and its scores are correlated with clinical AD indicators,making it a suitable tool for assessing dampness syndrome in this population.
