After participating in a brief, demythologizing seminar, 24 high school juniors reported significantly changed attitudes toward mental illness on a paper-and-pencil measure. These new attitudes reflected a rejection of the “mental illness” metaphor and, generally, less acceptance of the traditional medical model approach. Demythologizing also appeared to reduce significantly the students' ratings of fear of an hypothesized mental patient neighbor. A 5-wk. followup confirmed the stability of the changes in reported attitudes and fear ratings. Results are discussed within the context of their implications for community psychology. Replication is needed.
