This study explores the effects of a white, middle and upper-class preference system on the helping relationship. Evaluating people according to their monetary status, educational background, productiveness, and religious and social origins characterized many nursing students in the study. In an attempt to help students become aware of their own prejudices, examine their own value systems, and change their attitudes through understanding and acceptance of values different from their own, the study used exercises from human relations training such as role playing, racial slurs, and sensitivity groups. Following such exercises, subjects showed an increased awareness of the effects of racial prejudice on the helping relationship. (Author/LAA)
