Objective: Genetic testing for hereditary hearing impairment has become more routinely available as a diagnostic tool in the outpatient clinic. However, little is known about the psychological impact of a genetic diagnosis. To evaluate this impact, an exploratory study was conducted.Design: Prospectively, 48 individuals who underwent genetic testing for hereditary hearing impairment were included in this study. Study participants were asked to fill out the following questionnaires: Hospital Anxiety Depression Scale, Impact of Event Scale, Self-Efficacy 24, Illness Cognition Questionnaire and the Inventory for Social Reliance. Questionnaires were filled out on three occasions: before genetic testing, directly after counselling on either positive or negative test results, and six weeks thereafter.Results: No significant differences were found between the group that received a genetic diagnosis for their hearing impairment and the group that did not. Conclusion:This study did not demonstrate differences between receiving a genetic diagnosis or not; however, special attention to psychological well-being should be offered to hearing-impaired patients who seek a genetic diagnosis for their hearing impairment. Additionally, the psychological impact of sensorineural hearing impairment might be greater than the impact of a genetic diagnosis itself. Based on the current exploratory study, there are no psychological reasons in favour of or against genetic testing for hereditary hearing impairment.
