The role of vision and hearing in physical, social, and emotional functioning among older adults

The present study examined the comparative roles of vision and hearing in different aspects of older individuals' lives. The significance of vision and hearing on physical, social, and emotional functioning (disability, social activity, and depressive symptoms) was assessed along with the role of personality traits and social resources, using a stratified sample of 425 community-dwelling older individuals (M age = 72.2). Vision was a significant factor for disability, while hearing was significantly associated with social activity, implying the unique contribution of vision and hearing. The association between sensory performance and depressive symptoms became non-significant in multivariate analysis. After adjusting for vision and hearing, psychosocial factors increased the amount of explained variance in physical, social, and emotional outcomes. The findings demonstrate the important roles of personality and social resources along with vision and hearing and suggest a need to consider them when planning interventions.
