A survey of 118 MSW students was conducted to examine the relationship between social work students' knowledge about, contact with, and attitudes toward persons with schizophrenia. Hierarchical regression analyses indicated that students' knowledge about and contact with persons with schizophrenia were significantly related to better attitudes toward this population. Moderated multiple regression analyses revealed a significant interaction between knowledge about and contact with persons with schizophrenia, such that knowledge was only related to positive attitudes among students who had more personal contact with individuals with the illness. Implications for social work training in severe mental illness are discussed. (Contains 2 figures and 3 tables.)
