The social network characteristics of a culturally and racially diverse group of first-year college students (n=208) and white students (n=84) attending the same college were examined at the time of college entry and at the beginning of the second semester. Relationships between network characteristics and college adjustment in the second semester were also explored. White students reported larger social networks and more interaction with perceived sources of support than Asian and Latino/a students. Asian students obtained a larger percentage of support from college faculty/staff by the second semester than other students. Multiple regression analyses suggest that obtaining support from family members is positively associated with personal and social adjustment for students of color, while obtaining support from pre-college friends is negatively related with institutional attachment. For white college students, obtaining support from college friends was positively associated with social adjustment and institutional attachment. Having network members that increase one's self-esteem was associated with personal adjustment and institutional attachment for students of color and with academic, social and personal adjustment for white students. In addition, having network members that one could get together with for fun and relaxation was associated with social adjustment for students of color, and having network members that can be counted on to loan things was associated with social adjustment and institutional attachment.
