Abstract
Methods
The CADI was translated and linguistically validated into Serbian according to published guidelines. This version of CADI,
along with the Serbian version of Children’s Dermatology Life Quality Index (CDLQI) and a short demographic questionnaire,
was administrated to a cohort of secondary school pupils. The Global Acne Grading Score was used to measure the clinical severity
of acne. The internal consistency reliability of the Serbian version of CADI was assessed by Cronbach’s alpha coefficient
while its concurrent validity was assessed by Spearman’s correlation coefficient. Construct validity was examined by factor
analysis.

Results
A total of 465 pupils completed questionnaires. Self-reported acne was present in 76% of pupils (353/465). The Serbian version
of CADI showed high internal consistency reliability (Cronbach’s alpha coefficient = 0.79). The mean item-total correlation
coefficient was 0.74 with a range of 0.53–0.81. The concurrent validity of the scale was supported by a moderate but highly
significant correlation with the CDLQI (Spearman’s rho = 0.66; P < 0.001). Factor analysis revealed the presence of two dimensions underlying the factor structure of the scale.
