An investigation into the validity and reliability of the Hyperacusis Handicap Questionnaire for adults with normal auditory function

Objectives: The study aimed to investigate the validity and reliability of the Hyperacusis Handicap Questionnaire (HHQ) and to determine a cutoff score using the Khalfa Hyperacusis Questionnaire (KHQ). Patients and Methods: A total of 210 participants (161 females, 49 males; mean age: 27.9±8.0 years; range, 18 to 65 years) were included between August 2023 and April 2024. The instrument was translated into Turkish, after which its validity and reliability were assessed through exploratory factor analysis and confirmatory factor analysis. The HHQ and KHQ were utilized to establish a cutoff score with receiver operating characteristic analysis. Results: The scale demonstrated a high level of internal consistency, with a Cronbach's alpha of 0.92. Exploratory factor analysis indicated that the scale accounted for 52.51% of the total variance. Confirmatory factor analysis confirmed that the scale exhibited both perfect and acceptable fit. A cutoff score was established at 35. Conclusion: The HHQ, comprising 21 items across three factors, was established as a valid and reliable measurement tool. Its application, in conjunction with other diagnostic instruments, will provide valuable guidance in the assessment and monitoring of hyperacusis.
