This paper examines the structural relationships between community members’ attitudes toward the community living of developmental disabilities, their sense of community and exclusivity, determines any difference in the structural modeling paths through multi-group analysis relative to their contacts with developmental disabilities, and presents relevant implications. The analysis results highlight the positive effects of solidarity among other components of sense of community on community members’ attitudes, whereas their sense of belonging has no direct effects on their attitudes. The greater the solidarity, the less the exclusivity. In contrast, exclusivity increases with the sense of belonging, which in turn has negative effects on their attitudes. As for the difference in group-specific paths in relation to the contacts with developmental disabilities, a significant difference is found in the path where the sense of belonging exerts negative effects on exclusivity. These findings indicate the need for reinforcing the sense of community for the positive change in community members’ attitudes toward the community living of developmental disabilities.
