Supplementary Material for: Development and Evaluation of the Psychosocial Adaptation Questionnaire among Patients with Chronic Skin Disease

<b><i>Background/Objective:</i></b> Chronic skin disease (CSD) often has physiological, psychological, and social impacts, which requires the patient to adjust to achieve psychosocial adaptation (PSA). As a standardized assessment instrument was lacking, we developed a PSA questionnaire for patients with CSD (PSAQ-CSD). <b><i>Methods:</i></b> According to the steps of questionnaire development, a systematic process of scoping review, qualitative research, content validity expert review, testing in a sample of 321 adults, item analysis, and classical test theory methods were applied. <b><i>Results:</i></b> Following item analysis and exploratory factor analyses, 18 items were eventually entered into the model of confirmatory factor analyses, with a cumulative contribution of 65.435%. Three subscales were developed: emotional, self-cognitive, and social dimensions. Item analysis, exploratory factor analyses, and content validity expert review narrowed the subscales to 8, 6, and 4 items, respectively. <b><i>Conclusions:</i></b> The 18-item PSAQ-CSD has been confirmed to have good internal consistency reliability and convergent and discriminant validity. It may be a useful tool to evaluate the PSA among patients with CSD and provide a basis for further research.

背景与目标：慢性皮肤病（Chronic Skin Disease, CSD）往往会对患者造成生理、心理及社会层面的多重影响，要求患者进行适应性调适以达成社会心理适应（Psychosocial Adaptation, PSA）。鉴于当前缺乏标准化的评估工具，本研究研发了一款针对慢性皮肤病患者的社会心理适应问卷（Psychosocial Adaptation Questionnaire for Patients with Chronic Skin Disease, PSAQ-CSD）。研究方法：按照问卷研发的标准流程，本研究采用了范围综述（Scoping Review）、质性研究（Qualitative Research）、内容效度专家评审、对321名成人受试者施测、条目分析（Item Analysis）以及经典测验理论（Classical Test Theory）方法等系统研究步骤。研究结果：经条目分析与探索性因素分析（Exploratory Factor Analysis, EFA）后，最终纳入18个条目用于验证性因子分析（Confirmatory Factor Analysis, CFA）模型，累积方差贡献率达65.435%。本研究构建了3个分量表，分别为情绪维度、自我认知维度与社会维度。经条目分析、探索性因素分析及内容效度专家评审，各分量表分别包含8个、6个及4个条目。结论：本研究编制的18条目版PSAQ-CSD具有良好的内部一致性信度、会聚效度与区分效度，可作为评估慢性皮肤病患者社会心理适应水平的有效工具，为后续相关研究提供基础。
