The authors argue for the inclusion of students' subjective sense of belonging in an integrated model of student persistence (Cabrera et al., J Higher Educ 64:123-139, 1993). The effects of sense of belonging and a simple intervention designed to increase sense of belonging are tested in the context of this model. The intervention increased sense of belonging for white students, but not for African American students. However, sense of belonging had direct effects on institutional commitment and indirect effects on intentions to persist and actual persistence behavior for both white and African American students.
