| Abstract: | This study assesses whether a person's self-concept as a "chronic kidney patient" differentially moderates the psychosocial impact of illness intrusiveness—illness-induced lifestyle disruptions—across the life span. Renal transplant (n?=?52) and maintenance dialysis patients (n?=?49) completed the Illness Intrusiveness Ratings Scale, a semantic-differential self-concept measure, and structured interviews measuring psychosocial well-being and emotional distress. Across ages, distress rose with increasing illness intrusiveness when self-concept was similar, but not dissimilar, to the chronic kidney patient stereotype. The relation between illness intrusiveness and psychosocial well-being differed significantly between younger and older respondents depending on whether they construed themselves as similar versus dissimilar to the chronic kidney patient. Although self-definition moderates the psychosocial impact of chronic disease, this varies across the life span and across affect states.
