| Abstract | Background: Hearing loss (HL) is associated with adverse cognitive, mental, and physical health outcomes. There is evidence that across age groups HL is more prevalent in people with schizophrenia than the general population. Given that people with schizophrenia may already be vulnerable to cognitive and psychosocial disability, we sought to examine how hearing ability relates to concurrent levels of cognitive, mental and daily functioning. Methods: Community-dwelling adults with schizophrenia (N = 84) ages 22-50 completed pure tone audiometry assessments. Hearing threshold (in decibels) was defined as the lowest detectable pure tone at 1000 Hz. Pearson correlation was used to test the hypothesis that higher hearing thresholds (worse hearing) would be significantly associated with poorer performance on the Brief Assessment of Cognition in Schizophrenia (BACS). Additional analyses explored the relationships between audiometric threshold and functional capacity measured with the Virtual Reality Functional Capacity Assessment Tool (VRFCAT) and symptoms severity rated on the Positive and Negative Syndrome Scale (PANSS). Results: Hearing threshold was inversely and significantly correlated with the BACS composite score (r = -0.27, p = 0.017). This relationship was reduced but remained significant after controlling for age (r = -0.23, p = 0.04). Hearing threshold was not associated with VRFCAT or psychiatric symptom measures. Conclusions: While schizophrenia and HL are independently associated with cognitive impairment, the magnitude of impairment in this sample was greater among those with poorer hearing. Findings warrant further mechanistic study of the relationship between hearing impairment and cognition and have implications for addressing modifiable health risk factors for higher morbidity and mortality in this vulnerable population. |
