The patients were divided into 2 groups of 40 patients: group 1 was administered before the questionnaire and subsequently the interview was conducted, on the contrary on the group 2 was administered before the interview and subsequently the questionnaire. The results of the two groups were compared using the inter-rater agreement. It was also evaluated the internal consistency of the questions.
