Tinnitus (the perception of sound without an external source) affects over 740 million people globally. For older adults, tinnitus can worsen age-related declines in sleep and hearing, negatively impacting physical, social, and emotional well-being. Chronic tinnitus is linked to isolation, depression, and anxiety, which can increase the risk of suicidal thoughts. However, some older adults appear more resilient and better able to cope with the distress caused by tinnitus. Resilience-the ability to adapt and recover from adversity-may explain these differences, but the role of resilience in protecting against suicidal related behaviours in older adults with tinnitus is not well understood. This study aims to examine how tinnitus severity relates to suicidal ideation and behaviours in older adults and whether resilience helps reduce this risk. We will also explore whether sex and gender differences affect how people experience and cope with tinnitus, as men and women may have different responses to chronic conditions. Understanding these differences could lead to better, more personalized support for individuals suffering from tinnitus. To investigate these relationships, we will recruit 120 community dwelling older adults (aged 65 and over) to participate in a longitudinal study. Participants will complete one survey at the start of the study and the second survey after three months, measuring tinnitus severity, suicidal thoughts and behaviours, resilience, and other factors such as depression, anxiety, substance use, and social support. The study's findings will shed light on the mental health impacts of tinnitus in older adults and the potential protective role of resilience. By examining how sex and gender influence these relationships, we aim to develop tailored interventions to support those most at risk for poor mental health outcomes, helping to reduce the burden of tinnitus on older adults and improve their overall quality of life.
