This article reports a study based on A. W. Astin's (1984) involvement theory applied in residence halls at a public university in Hong Kong, China. The resident students who were involved as participants or student leaders in this study were found to be better developed in terms of leadership, career development, multicultural experience, community involvement, and ethical personal values. Implications for student affairs practice, considerations of cultural differences, involvement theory, future research, and study limitations are discussed.
