Friend or frenemy? Experiential homophily and educational track attrition among premedical students.

Support from experientially similar others-individuals who have been through the same life transition or faced a similar set of stressful circumstances-has been shown to be effective for coping with issues ranging from chronic illness to bereavement. Less research has examined how networks comprised of experientially similar others may shape academic outcomes. Using longitudinal egocentric network data collected from early career premedical students at a large research university (n = 268), results indicate that greater experiential homophily in premeds' networks are associated with a lower likelihood of departing from the premedical career track at the end of the academic year. Interview data (n = 39) highlight three support functions provided by premedical peers that help to explain this relationship: 1) concrete task assistance with assignments and studying, 2) empathic understanding and emotional support, and 3) advice and reassurance from more advanced peers. Results hint at the potential utility of peer support for the retention of students at-risk of straying from the premedical career track, and have implications for other fields of study.
