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

Background: 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. Objectives: The psychometric properties of a translated Chinese version of the Parental Self-Efficacy with Eczema Care Index (C-PASECI) were examined. Methods: 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. Results: 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 r = 0.53, p Conclusion: The C-PASECI appears to be a reliable and valid measure of parental self-efficacy in Chinese parents or caregivers of children with eczema.
