This qualitative study explored the experiences of Korean American (KA) immigrant parents of children with development disabilities (DDs) for their children with DDs living in the southeastern U.S. Using the Contextual Model of Family Stress as an organizing theoretical framework, we examined differences based on cultural characteristics, parents' gender, child's age, and diagnosis. Twenty KA parents of children with DDs participated in the study. We used grounded theory methods to analyze the data. Four major themes emerged including source of difficulties, source of support, perceptions of developmental progress, and personal transformations. The results indicated that KA parents shared similar experiences, but they varied depending on internal and external factors. Despite higher risk of stress, participants reported reframing challenges positively and using different types of support. However, parents who recently immigrated, lacked spousal support, and had children with severe symptoms appeared more vulnerable. We discuss implications for professionals working with this population.
