Assessment of adherence to eczema treatment in Hong Kong children

Abstract Introduction: Eczema is the most common childhood skin problem in Hong Kong. Treatment adherence is crucial in symptom management and the effectiveness of eczema management. The Problematic Experiences of Therapy Scale (PETS) is used to assess adherence to treatment among children with eczema. Objective: This study examined the psychometric properties of the translated Chinese version of PETS (C-PETS) among parents and caregivers of children with eczema. Methods: PETS was translated into Chinese and data obtained from a convenience sample of 147 Chinese participants from a regional hospital in Hong Kong. Results: The internal consistency of C-PETS with a Cronbach’s α of 0.93 and good test-retest reliability with weighted Kappa ranging from 0.74 to 0.89 were obtained. Significant positive correlations were found among the C-PETS, Children’s Dermatology Life Quality Index (r = 0.25, p = .002), and Severity Grading of Atopic Dermatitis scores (r = 0.38, p = .001). A significant negative correlation was found between C-PETS and Chinese adaptation of Generic Self-Efficacy scale (r = −0.40, p = .001). Confirmatory factor analysis showed that the data supported the structural validity of C-PETS. Conclusion: This study indicates that C-PETS is a reliable and valid measure to evaluate treatment adherence for Chinese parents and caregivers of children with eczema.
