There is a need to increase the persistence of women in science careers. This study focuses on undergraduate women majoring in or interested in science. Despite interest early on in their academic careers, women are leaving STEM at higher rates than other fields. Through the framework of the Tripartite Integration Model of Social Influence (TIMSI), this study explores psychosocial factors leading to integration in science careers. 484 undergraduate women from 9 universities in the Colorado/Wyoming Front Range and the Carolinas were recruited into this study and surveyed through 8 waves of data collection. A model building process was performed using HLM to study the impact of efficacy, identity, community values, and agentic and communal values on the persistence of undergraduate women in science over time.
