title: Comparison of Two Validated Voiding Questionnaires and Clinical Impression in Children With Lower Urinary Tract Symptoms: ICIQ-CLUTS Versus Akbal Survey.
abstract: OBJECTIVE
  To compare the correlation of 2 commonly used and validated voiding questionnaires (ICIQ-CLUTS and Akbal's) according to the physician's clinical impressions. Also, we investigated the reliability of these instruments in children with lower urinary tract symptoms (LUTS).
  
  
  METHODS
  Akbal's questionnaires and ICIQ-CLUTS forms were completed by children between 5 and 18 years old with and without LUTS and by their parents. The data were classified into 3 age groups (5-9, 10-13, 14-18). The reliability of Akbal and ICIQ-CLUTS was investigated by using Cronbach's α (≥0.7 is indicated acceptability). The total scores of the tools were compared with the physician's clinical impression (Kendall's tau b-test).
  
  
  RESULTS
  A total of 154 children (LUTS: n = 88, controls: n = 66) were prospectively enrolled into the study. The reliability of both instruments was excellent (Cronbach's alpha scores; Akbal = 0.811, ICIQ-CLUTS children version: 0.728 and ICIQ-CLUTS parental version: 0.746). When we compared by Kendal tau, Akbal was better correlated with physician's clinical impression. In addition, the children version of ICIQ-CLUTS was better correlated than parental version.
  
  
  CONCLUSIONS
  The results of our study provide that both tools are reliable and objective to grade the LUTS in pediatric population. Although both surveys were significantly correlated with clinical impression, the consistency of Akbal's questionnaire is found superior than that of ICIQ-CLUTS.
