Supplementary Material for: Translation and Validation of a Chinese Version of the Parental Self-Efficacy with Eczema Care Index

<b><i>Background:</i></b> Parental self-efficacy has been found to be a critical determinant of the efficacy of interventions intended to enhance the parental management of childhood eczema. <b><i>Objectives:</i></b> The psychometric properties of a translated Chinese version of the Parental Self-Efficacy with Eczema Care Index (C-PASECI) were examined. <b><i>Methods:</i></b> The PASECI was translated in a 2-stage process involving both forward and backward translation. Subsequently, the psychometric properties of the C-PASECI were examined in a cohort of 147 Chinese parents or caregivers of children with eczema. Specifically, the internal consistency, 2-day test-retest reliability and construct validity were assessed. <b><i>Results:</i></b> The C-PASECI received a Cronbach’s αof 0.97, and the intraclass correlation coefficients of each item ranged from 0.93 to 0.99. Negative correlations were observed among the C-PASECI, Children’s Dermatology Life Quality Index and Scoring Atopic Dermatitis Scale scores, indicating the acceptable convergent validity of the C-PASECI. The moderate correlation observed between the C-PASECI and General Self-Efficacy Scale (Pearson’s <i>r</i> = 0.53, <i>p</i> &lt; 0.001) reflected the acceptable concurrent validity of the C-PASECI. The results of confirmatory factor analysis supported the factorial validity of the C-PASECI. <b><i>Conclusion:</i></b> The C-PASECI appears to be a reliable and valid measure of parental self-efficacy in Chinese parents or caregivers of children with eczema.

**研究背景：** 现有研究表明，父母自我效能感是提升儿童湿疹患儿家长照护管理效果的干预措施有效性的关键决定因素。**研究目的：** 针对汉化版湿疹照护父母自我效能感量表（Parental Self-Efficacy with Eczema Care Index，C-PASECI）的心理测量学属性展开评估。**研究方法：** 采用双向翻译两阶段流程完成PASECI的汉化工作。随后，纳入147名中国儿童湿疹患儿的家长或照护者队列，对C-PASECI的心理测量学属性进行评估，具体包括内部一致性信度、2天重测信度以及结构效度。**研究结果：** C-PASECI的克朗巴赫α系数为0.97，各条目组内相关系数介于0.93至0.99之间。C-PASECI得分与儿童皮肤病生活质量指数（Children’s Dermatology Life Quality Index）、特应性皮炎评分量表（Scoring Atopic Dermatitis Scale）得分呈负相关，表明C-PASECI具备可接受的会聚效度。C-PASECI与一般自我效能感量表（General Self-Efficacy Scale）得分呈中等程度相关（Pearson相关系数r=0.53，p<0.001），提示其具有可接受的同时效度。验证性因子分析结果证实了C-PASECI的因子结构效度。**研究结论：** 对于中国儿童湿疹患儿的家长或照护者而言，C-PASECI是一份可靠且有效的父母自我效能感测评工具。
