The current study focused on examining the relationships of positive social attitudes with aspects of well-functioning. "Universal-diverse orientation" (UDO), a social attitude characterized by awareness and acceptance of both the similarities and differences among people, was measured with the Miville-Guzman Universality-Diversity Scale, Short Form (MGUDS-S; Miville et al., 1999; Fuertes et al., 2000). The MGUDS-S contains three subscales: Diversity of Contact, Relativistic Appreciation, and Comfort with Differences. The MGUDS-S was administered with measures of well-functioning. In the first condition, 183 undergraduates completed the MGUDS-S and scales measuring coping skills, positive thinking, self-efficacy, and optimism. In the second condition, 107 undergraduates completed the MGUDS-S and scales measuring social connectedness, personal self-esteem, and collective self-esteem. Multivariate multiple regression analyses revealed the MGUDS-S subscales were significantly predicted by social self-efficacy, general self-efficacy, problem-focused coping, collective self-esteem, and gender. Implications for future research and practice are discussed. (Contains 2 tables.)
