The profession of social work advocates for civil rights for gay men, lesbians, and bisexual persons. However, a number of social work students and practitioners harbor antigay bias that in prior variable-centered research has been determined to be related to race, relationship status, and age. The purpose of this research was to use latent class analysis (LCA), a person-centered statistical technique, to cluster 394 university student survey responses to the Attitudes Toward Lesbian and Gays short-form instrument. The analyses indicated three groups that can be profiled as unbiased, moderately biased, and highly biased. Analysis of variance and multinomial regression verified LCA findings that are consistent with prior research. The importance of selecting appropriate educational approaches to address antigay bias among social work students and practicing social workers is discussed, and recommendations for continued research, including a national random survey of social work students and licensed social workers, are made.
