Development of a Tool to Measure Student Perceptions of Equity and Inclusion in Medical Schools.

Importance: Creating an inclusive and equitable learning environment is a national priority. Nevertheless, data reflecting medical students' perception of the climate of equity and inclusion are limited. Objective: To develop and validate an instrument to measure students' perceptions of the climate of equity and inclusion in medical school using data collected annually by the Association of American Medical Colleges (AAMC). Design, Setting, and Participants: The Promoting Diversity, Group Inclusion, and Equity tool was developed in 3 stages. A Delphi panel of 9 members identified survey items from preexisting AAMC data sources. Exploratory and confirmatory factor analysis was performed on student responses to AAMC surveys to construct the tool, which underwent rigorous psychometric validation. Participants were undergraduate medical students at Liaison Committee on Medical Education-accredited medical schools in the US who completed the 2015 to 2019 AAMC Year 2 Questionnaire (Y2Q), the administrations of 2016 to 2020 AAMC Graduation Questionnaire (GQ), or both. Data were analyzed from August 2020 to November 2023. Exposures: Student race and ethnicity, sex, sexual orientation, and socioeconomic status. Main Outcomes and Measures: Development and psychometric validation of the tool, including construct validity, internal consistency, and criterion validity. Results: Delphi panel members identified 146 survey items from the Y2Q and GQ reflecting students' perception of the climate of equity and inclusion, and responses to these survey items were obtained from 54 906 students for the Y2Q cohort (median [IQR] age, 24 [23-26] years; 29 208 [52.75%] were female, 11 389 [20.57%] were Asian, 4089 [7.39%] were multiracial, and 33 373 [60.28%] were White) and 61 998 for the GQ cohort (median [IQR] age, 27 [26-28] years; 30 793 [49.67%] were female, 13 049 [21.05%] were Asian, 4136 [6.67%] were multiracial, and 38 215 [61.64%] were White). Exploratory and confirmatory factor analyses of student responses identified 8 factors for the Y2Q model (faculty role modeling; student empowerment; student fellowship; cultural humility; faculty support for students; fostering a collaborative and safe environment; discrimination: race, ethnicity, and gender; and discrimination: sexual orientation) and 5 factors for the GQ model (faculty role modeling; student empowerment; faculty support for students; discrimination: race, ethnicity, and gender; and discrimination: sexual orientation). Confirmatory factor analysis indicated acceptable model fit (root mean square error of approximation of 0.05 [Y2Q] and 0.06 [GQ] and comparative fit indices of 0.95 [Y2Q] and 0.94 [GQ]). Cronbach α for individual factors demonstrated internal consistency ranging from 0.69 to 0.92 (Y2Q) and 0.76 to 0.95 (GQ). Conclusions and Relevance: This study found that the new tool is a reliable and psychometrically valid measure of medical students' perceptions of equity and inclusion in the learning environment.

Perspectives on National Institutes of Health Funding Requirements for Racial and Ethnic Diversity Among Medical Scientist Training Program Leadership.

Importance: Since 1964, the National Institutes of Health (NIH) has funded the Medical Scientist Training Program (MSTP) MD-PhD program at medical schools across the US to support training physician-scientists. Recent studies have suggested that MSTPs have consistently matriculated more students from racial and ethnic backgrounds historically underrepresented in science than MD-PhD programs without NIH funding; however, the underlying basis for the increased diversity seen in NIH-funded MSTPs is poorly understood. Objective: To investigate how administrators and faculty perceive the impact of MSTP status on MD-PhD program matriculant racial and ethnic diversity. Design, Setting, and Participants: This qualitative study used a positive deviance approach to identify 9 high-performing and 3 low-performing MSTPs based on the percentage of students underrepresented in science who matriculated into the program between 2014 and 2018. This study, a subanalysis of a larger study to understand recruitment of students underrepresented in science at MSTPs, focused on in-depth qualitative interviews, conducted from October 26, 2020, to August 31, 2022, of 69 members of MSTP leadership, including program directors, associate and assistant program directors, and program administrators. Main Outcomes and Measures: The association of NIH funding with institutional priorities, programs, and practices related to MD-PhD program matriculant racial and ethnic diversity. Results: The study included 69 participants (mean [SD] age, 53 [10] years; 38 women [55%]; 13 African American or Black participants [19%], 6 Asian participants [9%], 12 Hispanic participants [17%], and 36 non-Hispanic White participants [52%]). A total of 51 participants (74%) were in administrative roles, and 18 (26%) were faculty involved in recruitment. Five themes emerged from the data: (1) by tying MSTP funding to diversity efforts, the NIH created a sense of urgency among MSTP leadership to bolster matriculant diversity; (2) MD-PhD program leadership leveraged the changes to MSTP grant review to secure new institutional investments to promote recruitment of students underrepresented in science; (3) MSTPs increasingly adopted holistic review to evaluate applicants to meet NIH funding requirements; (4) MSTP leadership began to systematically assess the effectiveness of their diversity initiatives and proactively identify opportunities to enhance matriculant diversity; and (5) although all MSTPs were required to respond to NIH criteria, changes made by low-performing programs generally lacked the robustness demonstrated by high-performing programs. Conclusions and Relevance: This study suggests that NIH funding requirements may be a powerful incentive to promote diversity and positively affect representation of students underrepresented in science in the biomedical scientific workforce.
