Describes results of study of a 45-item scale developed to measure the construct and administered to four separate samples. The Miville-Guzman Universality-Diversity Scale significantly correlated in theoretically predicted ways with measures of racial identity, empathy, health narcissism, feminism, androgyny, homophobia, and dogmatism (the last two correlations were negative). The data suggests considerable reliability and initial construct validity for the M-GUS. (Author/JDM)
