Aims: The purpose of this study was to assess health-related quality of life (HRQoL) among Serbian adolescents with acne, using 2 questionnaires: The Children's Dermatology Life Quality Index (CDLQI) and the Cardiff Acne Disability Index (CADI) and to provide a cross validation of 2 scales. Methods: This cross-sectional study was conducted among the pupils of the secondary railway-technical school in Belgrade, Serbia. 478 pupils (aged 15 - 18 years) completed 2 HRQoL questionnaires: CDLQI and CADI. We used t-test for differences between mean values of CDLQI and CADI and Spearman's rho coefficient for correlation between 2 questionnaires. Results: Self-reported acne was present in 71.6% of pupils (64.3% boys and 35.7% girls). The overall mean CDLQI score (4.35 of max. 30) and the overall mean CADI score (3.57 of max. 15) were low, indicating a mild impairment of HRQoL among adolescants. There was good correlation between the 2 questionnaires (Spearman' rho = 0.66). Conclusion: The CADI and the CDLQI questionnaires represent simple and reliable instruments for the assesment of HRQoL among schoolchildren with acne. In this study, we identified 17% of boys and 18% of girls perceived their acne as a major problem. It is important to detect and treat such adolescents on time to reduce the psychosocial burden associated with acne.AcneCardiff Acne Disability IndexChildren's Dermatology Life Quality Indexhealth related quality of lifeschoolchildren
