Using a sample of 124 incoming social work graduate students, we examined whether levels of perceived incongruence with social work values and the perceived culture of a graduate social work program significantly correlate with social psychological constructs. The social psychological constructs are associated with maintenance and support for social stratification in general and with prejudicial attitudes based on sexual orientation more specifically. Results suggest that higher levels of cultural incongruence are associated with significantly higher levels of right-wing authoritarianism, social dominance orientation, hostile heterosexism, aversive heterosexism, and paternalistic heterosexism. Nonsignificant results emerged for amnestic heterosexism and positive stereotypic heterosexism. Implications for social work education and future research are discussed.
