This study examined the relationship between adult educators' multicultural effectiveness scores and their negotiation of similarities and differences scores. The participants were in faith-based institutions, specifically Christian churches and in graduate adult education programs of universities and colleges in the United States. Multicultural effectiveness was measured by the Multicultural Personality Questionnaire (MPQ) that the authors reported measured multicultural effectiveness as the primary, encompassing variable. The MPQ is a five-point Likert scale with 91 items. The MPQ reliability was a Cronbach's alpha of 0.82 (Van der Zee & Van Oudenhoven, 2000). The Miville-Guzman Universality-Diversity Scale (M-GUDS) measured the negotiation of similarities and differences. The M-GUDS is a six-point Likert scale with 45 items on the long form and 15 items on the short form. Its internal consistency and reliability were high measuring Cronbach's alpha 0.89 (Miville et al., 1999). There were 40 participants in the study. A Pearson Correlation indicated a significant correlation, r (38)=0.59, p<0.001, between MPQ and M-GUDS scores. The positive correlation demonstrated that as the MPQ scores increased the M-GUDS scores increased. There were no differences in scores between faith-based adult educators and individuals in graduate adult education programs. The mean score for MPQ was 316.94. The mean score for the M-GUDS was 152.82. The highest scores were from faith-based educators in predominantly African American, non-denominational churches. Their M-GUDS scores were above 140 and the MPQ scores were between 275 and 375. The majority of those educators also focused on social action. There were 18 males and 21 females. The males had slightly higher scores on both scales. [The dissertation citations contained here are published with the permission of ProQuest LLC.
