Social capital plays a key role in college students' academic and career success. Using a random assignment design, the current study evaluated the impacts of a one-credit college course designed to increase student help-seeking and social capital within a racially diverse sample of college students. Compared to the control group, students in the treatment group reported improved attitudes towards help-seeking, increased help-seeking behavior, and higher levels of social capital and mentoring support. Academic benefits were mixed, however, with an increase in academic self-efficacy, no impact on college GPA, and a decrease in academic cognitive engagement. Additionally, differential impacts based on year in college, race, and first-generation college student status were observed. Implications for research and practice are discussed.
