BACKGROUND: Preoperative @entity148 is usually experienced by @entity1 awaiting surgical procedures and it can negatively impact @entity1 's outcome. The Amsterdam Preoperative @entity148 and Information Scale (APAIS) is a questionnaire created to identify anxious @entity1 and their need for information: it has been translated and validated in many languages because of its reliability and ease of completion. To date, no Italian version of the APAIS has been produced; our aim was to translate and validate the APAIS in Italian. METHODS: We produced an Italian version of the APAIS and we administered it to 110 @entity1 undergoing elective surgery; we explored its structure by factor analysis and its reliability by Cronbach's alpha. We analyzed its external validity by confronting it to the Spielberg's State-Trait @entity148 Inventory (STAI). Sensitivity, specificity, and positive and negative predictive values of Italian version of the APAIS were determined. RESULTS: Italian version of the APAIS confirmed the original structure of the questionnaire and its internal consistency; it well correlated with the STAI-Y1, the subscale of the STAI which explore the @entity148 "state". An APAIS score of 14 was found as best cutoff to distinguish anxious and non-anxious @entity1 . CONCLUSIONS: Italian translation of the APAIS showed psychometric properties similar to the original version. Its reliability and its efficiency make it a powerful tool even in Italian population to detect @entity148 and need for information.
