Validity and reliability study of the Khalfa’s hyperacusis questionnaire with using ULL in tinnitus patients

Purpose This study aims to investigate the validity and reliability of the Khalfa’s hyperacusis questionnaire (HQ) in Turkish tinnitus patients with hyperacusis using uncomfortable loudness levels (ULLs) and to determine a cutoff score for tinnitus patients specifically. Materials and methods One hundred and forty subjects with a mean age ± SD of 45.27 ± 14.43 years ranging from 18 to 75 participated in the study. HQ and ULLs were used as measures of hyperacusis. The participants were divided into two groups due to ULLs ≤ 90 dB in one or both ears (Group 1) and 56 participants have ULLs > 90 dB (Group 2). Results The mean HQ score of the participants was 19.55 ± 7.18 points, Group 1 ( n = 84) HQ mean score was 21.97 ± 7.08, and Group 2 ( n = 56) 15.91 ± 5.56 points, and the cutoff point was found 16.50. Statistically significant differences were found between the groups in total HQ ( p
