Original abstract

<b>Background:</b> Tinnitus is common among Veterans and is associated with PTSD and traumatic brain injury (TBI).<b>Objective:</b> To characterize tinnitus and examine the overlap of tinnitus, PTSD, and TBI and their relative associations with sleep disturbance, chronic pain, and cognitive and functional impairment.<b>Method:</b> Participants were 735 primarily young (<i>M</i> = 34.7, <i>SD</i> = 9.1), male (90.2%) post-9/11 US Veterans. Hierarchical regressions were performed to determine whether additional variance in cross-sectional and longitudinal health outcomes was explained by tinnitus beyond PTSD and TBI.<b>Results:</b> Tinnitus was common (67.5%) and evidenced substantial comorbidity with both PTSD and TBI in 35.6% of the sample. Tinnitus explained an additional 1.9-3% of the variance (both Δ <i>p</i> < .001) in pain (β = .184, <i>p</i> < .001) and functional impairment (β = .145, <i>p</i> < .001) after accounting for PTSD severity and number of TBIs and adjusting for multiple testing. PTSD significantly predicted all outcomes (βs = -.226 -.657, all <i>p</i>s < .001). Tinnitus showed stability over time but did not predict later pain or functional impairment.<b>Conclusions:</b> Results suggest tinnitus is common among young treatment-seeking Veterans and highlight the need for future research aimed at reducing the toll of this chronic condition. Tinnitus should be evaluated alongside PTSD and TBI, as it may be associated with more negative health outcomes, even among those already at increased risk due to PTSD and TBI. Clinicians should be informed about best practices for managing tinnitus in efforts to improve health and well-being.
