title: Question for a questionnaire: the International Index of Erectile Function.
abstract: The aim of this study was to analyze the impact of patient age and education level on the comprehension of the Turkish version of Index of Erectile Function (IIEF), and to determine the patient characteristics that make this questionnaire less reliable. In this study, 238 male patients presenting to our clinic were enrolled. The patients were asked to complete the Turkish version of the IIEF questionnaire upon arrival by themselves and then once again during their second visit with the assistance of a physician. 'Accurate' comprehension of the IIEF was considered to be the consistency between the 'self-administered' and 'physician-assisted' IIEF scores. The impact of patient age and education level on the 'accurate' comprehension of the IIEF was analyzed. There was a significant difference between the 'self-administered' and 'physician-assisted' IIEF scores in patients ≥ 60 years of age (P=0.045) and primary school graduates (P=0.015). Age ≥ 60 years and being primary school graduate are factors lowering the comprehension of the Turkish version of the IIEF by the patients. Older patients and patients with lower education could benefit from the assistance of a physician while completing this questionnaire.
