Background. Skin diseases that are longstanding or highly symptomatic can have devastating consequences in the quality of life of children. There is a need to have a validated Filipino translation of a dermatology quality of life tool for young patients with skin diseases. Objectives. To assess the validity and reliability of the Indeks ng Kalidad ng Buhay Pang-dermatolohiya ng mga Bata (IKPaB), a Filipino translation of the Children’s Dermatology Life Quality Index (CDLQI). Methods. This cross-sectional study was conducted among children aged 4 to 16 years at a tertiary hospital outpatient department. The IKPaB was pretested and revised using focus group discussion until it was approved by the original developers for validation. Face validity was determined through cognitive debriefing interviews. Construct validity was determined by comparing IKPaB scores of participants with skin disease and without skin disease using Mann-Whitney U test. Criterion validity was determined by comparing IKPaB with a validated Filipino-translated PedsQL as the criterion, using Spearman rank correlation. Internal consistency reliability was determined using Cronbach’s coefficient. Multiple regression was used to correlate age, sex and disease duration. Results. The IKPaB was assessed to be comprehensible, clear, and culturally appropriate. Among 288 participants, it showed satisfactory construct validity (U = 8849, Z= 0.87; P = 0.89) and internal consistency reliability (α = 0.89), with a negative but weak correlation with the PedsQL® (rho= -0.300, P = 0.000). Conclusion. The IKPaB is a valid and reliable Filipino translation of CDLQI. We recommend further validation for use in clinical practice and research.
