Acculturative stress is associated with negative mental health among culturally diverse individuals. Deaf and Hard-of-Hearing (DHH) individuals experience acculturative stress as they navigate within and between the Hearing and Deaf communities, yet, research has not examined the relationship between deaf acculturative stress and psychological functioning. This study examined the relationships between deaf acculturative stress, well-being, and symptoms of depression and anxiety. One hundred and ten DHH adults (71.6% female, 82.7% White, median age = 30–39) completed an online survey including the Multidimensional Inventory of Deaf Acculturative Stress (MIDAS), demographic questions, and measures of psychological functioning. After controlling for relevant sociodemographic factors, the MIDAS Stress from the Deaf and Hearing Community scales emerged as significant predictors of well-being and symptoms of anxiety and depression. Findings are discussed within the context of DHH sociocultural experiences, and suggestions for future research are offered to inform clinical work with DHH individuals.
