title: Quality of life among schoolchildren with acne: results of a cross-sectional study.
abstract: BACKGROUND
  Acne is a common problem in adolescent children and has a considerable impact on their quality of life.
  
  
  OBJECTIVE
  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).
  
  
  CONCLUSIONS
  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.
