The present study aims to evaluate and validate the Italian version of Khalfa's questionnaire on @entity7804 (HQ). We recruited 117 @entity1 (64 @entity1 , 53 @entity1 , mean age 53 years, range 14-88) with @entity392 for at least 3 months as a @entity74 . All @entity1 completed the THI and the Italian version of the HQ and underwent audiometry, pitch and loudness @entity392 matching, otoacoustic emissions with distortion products (DPOAE) and uncomfortable loudness level (ULL). The overall performance of the tests was evaluated and compared using the area under the RO C curve (AUC) relative to the tests. The cut-off of the HQ was calculated. We also assessed the Cronbach's alpha (aC) for the HQ and its three major dimensions (attentional - @entity23036 , emotional - @entity43907 and social - @entity63496 ). Statistical analysis showed no correlation between DPOAE, audiometry, ULL and gender. We observed a high correlation (p < 0.05) between @entity7804 and ULL described by the Spearman's    index (rs = 0.72). We found a cut-off of 16 indicative of @entity7804 comparing the area under the RO C curve (AUC) of HQ and audiometry, taken as a diagnostic reference, (sensitivity = 67.9% and specificity = 72.2%). The reliability of HQ was confirmed by a high aC = 0.89. The aC for the single dimensional scales were, respectively, @entity23036 = 0.73, @entity43907 = 0.72 and @entity63496 = 0.81. The Italian version of the HQ is recommended for proper and complete classification of @entity1 with @entity392 and @entity7804 . From our study, we found a cut-off of 16 instead of the cut-off of 28 described as very high by other authors. Moreover, ULL was an important variable and can be discriminating in the evaluation of @entity7804 .
