There is a substantial lack of knowledge on the impact of reduced hearing on psychosocial functioning in young and middle-aged adults. This study addresses this issue. Baseline data of the National Longitudinal Study on Hearing, including 1511 participants (18 - 70 years, Mean: 46.3 years) are analyzed. Hearing status was determined using a speech-in-noise test over the Internet. Psychosocial health was assessed using online questionnaires. Significant associations between reduced hearing and distress, somatization, depression and loneliness are found. The associations differ among age groups The findings underline the need to address the adverse effects of limited hearing among young and middle-aged adults both in research and clinical practice.
