Measurement Properties of the Hearing Environments and Reflection of Quality of Life (HEAR-QL) 28-item Questionnaire in Cholesteatoma.

OBJECTIVE

We sought to assess the reliability and construct validity of the Hearing Environments and Reflection on Quality of Life Adolescent (HEAR-QL 28) quality of life measure (QoL) in cholesteatoma.

STUDY

DESIGN

Observational.

SETTING

Tertiary referral center.

PATIENTS: One hundred seventeen patients with a diagnosis or history of cholesteatoma completed HEAR-QL 28. In addition to patients within the age range recommended for HEAR-QL 28 (13-18 yr), patients under 13 years old who were able to complete HEAR-QL 28 without parental assistance were included.

INTERVENTION S: Completion of HEAR-QL 28 QoL measure.

MAIN OUTCOME MEASURE S: HEAR-QL 28 score, four tone average pure tone audiogram hearing threshold and categorical classification of hearing loss as mild, moderate, and severe.

RESULTS

HEAR-QL 28 did not demonstrate discriminative ability on the basis of audiometric threshold, but did discriminate between participants hearing normally (four tone average pure tone audiogram <30 dB HL) (HEAR-QL 86/100) after cholesteatoma surgery from those with unilateral hearing loss (HEAR-QL 73/100) (p < 0.001). Those with unilateral loss could in turn be differentiated from those with bilateral loss (HEAR-QL 60/100) (p < 0.006).

CONCLUSION

HEAR-QL 28 is valid measure of QoL in cholesteatoma with no evidence of redundancy and excellent internal consistency. The importance of considering QoL impact of cholesteatoma is highlighted by 17% of participants reporting the normality or abnormality of their hearing differently from their audiometric threshold. The HEAR-QL 28 provides insight into the ability to cope with their hearing environment in a specific environment.
