Psychological Predictors of Medical Students’ Involvement in Pro Bono

Theory: Medical pro bono, in which medical professionals provide no (or low) cost services, is one approach to addressing unmet healthcare needs. Prior efforts to understand who chooses to take part in pro bono and why they might do so have been primarily atheoretical in their approach. The current investigation focuses on students in medical school and draws on relevant theory and research in psychology to identify predictors of their intentions to engage in medical pro bono service during and after medical school. Hypotheses:Four major approaches to identifying predictors of medical pro bono are examined: the role of demographic variables as predictors of medical pro bono, conceptualizing medical pro bono as a form of volunteerism, viewing medical pro bono as an expression of personality, and medical pro bono as a reflection of role identities and expectations. Each of these approaches can be characterized as being about medical students’ individual attributes or aspects of the situation they are in. Methods: A total of 278 medical students from 15 different medical schools in the United States of America completed a web-based survey (8/4/2020–9/22/2020). The students completed measures of pro bono identity and expectations, intentions to engage in medical pro bono activities, prosocial personality, volunteer motivation, exposure to volunteering, general traits of personality, and demographic variables (in this order). We used linear regression analyses to separately predict three measures of intentions (general medical school intentions, intentions toward medical pro bono trips during medical school, and general post medical school intentions). Results: The strongest predictors of intentions to engage in medical pro bono were one’s identity and expectations related to pro bono. Medical students who had incorporated medical pro bono into aspects of their identity and/or considered medical pro bono to be an expectation indicated higher intentions to engage in medical pro bono work. Conversely, volunteer motivation/exposure, personality, and demographic variables were much weaker predictors of medical pro bono. Conclusions: The findings of the present study have implications for ways that medically oriented volunteering may be increased by individual-level interventions and/or changes in medical education. Individual-level interventions could leverage the importance of identity and expectations to craft persuasive messaging to appeal to identity and expectations as drivers of engagement in medical pro bono. Program level interventions could work toward the institutionalization of medical pro bono by the inclusion/promotion of medical pro bono into the program’s co-curricular and/or extracurricular activities.
