title: Critical points in understanding the Italian version of the IIEF 5 questionnaire.
abstract: OBJECTIVE
  The aim of these study is to assess the understanding of the Italian version of the IIEF-5 questionnaire (International Index of Erectile Function) and the impact of patient's demographic and clinical characteristics on it.
  
  
  METHODS
  Each patient was asked to self complete the Italian version of the IIEF-5 questionnaire and to self report demographic information and any difficulties to complete the questionnaire and which question was considered more difficult to understand.
  
  
  RESULTS
  A total of 89 patients were included in this study. Patients mean age was 61.2 +/- 15.4 (standard deviation = SD) years. The mean IIEF score at the time of the visit was 13.5 +/- 8.5 (SD). The questions considered more difficult to understand were number 5 (26%), number 4 (20%) and number 1 (20%). Statistically significant differences between patients with and without problems in completing the questionnaire were found in terms of education level (p = 0.0026).
  
  
  CONCLUSIONS
  Patients with a lower educational level have more difficulties in understanding the questionnaire and the most difficult questions are items number 5, 4 and 1.
