Abstract:
To assess the reliability, validity and responsiveness of the Chinese version of the atopic dermatitis control tool (ADCT). After this study obtained authorization for the Chinese version of the ADCT scale. 114 patients with atopic dermatitis were enrolled from the Department of Dermatology, Peking University First Hospital using convenience sampling from October 2022. Patients were surveyed using the General Information Questionnaire, Chinese version of ADCT, patient-oriented eczema measure (POEM),peak pruritus numerical rating scale (PP-NRS),dermatology life quality index (DLQI) and the global patient self-assessment for disease severity. Mann-Whitney rank sum test and Spearman correlation analysis were used for item analysis; content validity was assessed using content validity index (CVI); exploratory factor analysis was used to assess structural validity; Cronbach' alpha coefficient was used to assess internal consistency; Spearman correlation analysis was used to assess the correlation of ADCT with other scales to assess external responsiveness. The results showed that all items were retained by item analysis. I-CVI was 0.9-1, and S-CVI/Average was 0.983; the scale extracted one common factor by factor analysis, the cumulative variance explanation rate was 77.927%; the Cronbach' alpha coefficient of the scale was 0.937; the correlation coefficients of the Chinese version of ADCT with POEM, PP-NRS, and DLQI were 0.805, 0.861, and 0.709 respectively. In conclusion, the Chinese version of the ADCT has adequate reliability, validity and responsiveness, and is suitable for measuring disease control in Chinese patients with atopic dermatitis.
