Reliability and validity of a new scale to measure prejudice: The GRISMS

The goal of the present research was to assess the reliability and validity of the fiftyitem Modified Godfrey-Richman ISM Scale (M-GRISMS). The sample consisted of seventy-one female and sixty male introductory psychology students. Test items included various ethnic groups (Racism subscale), religious groups (Religion subscale), and the Heterosexist and Sexist subscales. Each of these was parsed into various subcategories, e.g., the Racism subscale assessed attitudes toward African-Americans, Asian-Americans, European-Americans, Hispanics, and Native Americans. The final version of the M-GRISMS (the M-GRISMS-M) was found to be highly reliable and valid. Eight independent factors traversed two or more “isms.”
