Development and Evaluation of the Psychosocial Adaptation Questionnaire among Patients with Chronic Skin Disease

Abstract

<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.
