ABSTRACT

INTRODUCTION: Improved mentoring of midcareer researchers in medical schools has been identified as an important potential avenue for addressing low vitality and high burnout rates in faculty, and the scarcity of both underrepresented minority (URM) faculty and women in biomedical research. To address the need for widescale effective mentoring, we sought to determine whether a group peer mentoring intervention (C-Change Mentoring and Leadership Institute) for early midcareer research faculty was effective for different demographic groups in a controlled trial. METHODS AND MATERIALS: Thirty-five diverse early midcareer faculty and 70 propensity-matched (PM) control subjects matched to intervention subjects on a) study inclusion criteria; b) gender, race, and ethnicity, degree, rank, years of experience, publications, grants; and c) pretest survey outcome variables, participated in the intervention. The C-Change Participant Survey assessed vitality, self-efficacy in career advancement, research success, mentoring others, valuing diversity, cognitive empathy, and anti-sexism/anti-racism skills at pretest and intervention completion. Analysis using multiple regression models included outcome pretest values and indicator variables for intervention, gender, URM status, and MD vs. PhD. Hypotheses regarding differential effectiveness of the intervention by demographic group were tested by including cross-product terms between the demographic indicator variables and the intervention indicator. Missing data were addressed using chained equations to create 100 data sets. RESULTS AND DISCUSSION: The intervention participants had significantly higher (favorable) scores than PM controls for: self-assessed change in vitality; self-efficacy for career advancement, research, and mentoring others; cognitive empathy; and anti-sexism/racism skills. The benefits of the intervention were nearly identical across: gender, URM vs non-URM faculty, and degree MD/PhD, except vitality significantly increased for non-URM subjects, and not for URM faculty. Self-assessed change in vitality increased for URM and non-URM. CONCLUSION: The intervention worked successfully for enhancing vitality, self-efficacy and cross-cultural engagement across different demographic groups of biomedical research faculty.

ABSTRACT

Introduction: Midcareer is a critical transition point for biomedical research faculty and a common dropout point from an NIH-funded career. We report a study to assess the efficacy of a group peer mentoring program for diverse biomedical researchers in academic medicine, seeking to improve vitality, career advancement, and cross-cultural competence. Methods: We conducted a stratified randomized controlled trial with a waitlist control group involving 40 purposefully diverse early midcareer research faculty from 16 states who had a first-time NIH R01 (or equivalent) award, a K training grant, or a similar major grant. The yearlong intervention (2 to 3 days quarterly) consisted of facilitated, structured, group peer mentoring. Main study aims were to enhance faculty vitality, self-efficacy in achieving research success, career advancement, mentoring others, and cultural awareness and appreciation of diversity in the workplace. Results: Compared to the control group, the intervention group's increased vitality did not reach statistical significance (P = 0.20), but perceived change in vitality was 1.47 standard deviations higher (D = 1.47, P = 0.03). Self-efficacy for career advancement was higher in the intervention group (D = 0.41, P = 0.05) as was self-efficacy for research (D = 0.57, P = 0.02). The intervention group also valued diversity higher (D = 0.46, P = 0.02), had higher cognitive empathy (D = 0.85, P = 0.03), higher anti-sexism/racism skills (D = 0.71, P = 0.01), and higher self-efficacy in mentoring others (D = 1.14, P = 0.007). Conclusions: The mentoring intervention resulted in meaningful change in important dimensions and skills among a national sample of diverse early midcareer biomedical faculty. This mentoring program holds promise for addressing the urgencies of sustaining faculty vitality and cross-cultural competence.

ABSTRACT

Introduction: Midcareer research faculty are a vital part of the advancement of science in U.S. medical schools, but there are troubling trends in recruitment, retention, and burnout rates. Methods: The primary sampling frame for this online survey was recipients of a single R01 or equivalent and/or K-award from 2013 to 2019. Inclusion criteria were 3-14 years at a U.S. medical school and rank of associate professor or two or more years as assistant professor. Forty physician investigators and Ph.D. scientists volunteered for a faculty development program, and 106 were propensity-matched controls. Survey items covered self-efficacy in career, research, work-life; vitality/burnout; relationships, inclusion, trust; diversity; and intention to leave academic medicine. Results: The majority (52%) reported receiving poor mentoring; 40% experienced high burnout and 41% low vitality, which, in turn, predicted leaving intention (P < 0.0005). Women were more likely to report high burnout (P = 0.01) and low self-efficacy managing work and personal life (P = 0.01) and to be seriously considering leaving academic medicine than men (P = 0.003). Mentoring quality (P < 0.0005) and poor relationships, inclusion, and trust (P < 0.0005) predicted leaving intention. Non-underrepresented men were very likely to report low identity self-awareness (65%) and valuing differences (24%) versus underrepresented men (25% and 0%; P < 0.0005). Ph.D.s had lower career advancement self-efficacy than M.D.s (P < .0005). Conclusions: Midcareer Ph.D. and physician investigators faced significant career challenges. Experiences diverged by underrepresentation, gender, and degree. Poor quality mentoring was an issue for most. Effective mentoring could address the concerns of this vital component of the biomedical workforce.

ABSTRACT

PURPOSE: We report on the extent of sexual harassment among residents and examine its relationship to specialty and program year and effects. METHODS: Using the C-Change Resident Survey, we surveyed residents in 34 internal medicine, pediatrics, and general surgery programs in 14 academic medical centers (AMCs). A total of 1708 residents completed the survey (70% response-rate); 51% (n = 879) were women. Respondents reported unwanted sexual comments, attention, or advances by a superior or colleagues within the last 2 years. Measures of vitality and ethical or moral distress were included in the surveys. RESULTS: Rates of sexual harassment reported by women differed across the 34 programs, with an interquartile range of 0%-11%. Residents in pediatrics had the lowest frequencies of sexual harassment (mean 2%, 95% confidence interval [CI] 0%, 4%). Residents in internal medicine had higher rates of sexual harassment (mean 7%, 95% CI 1%, 25%). Residents in surgery had the highest rates (mean 12%, 95% CI 2%, 33%). Sexual harassment was associated with lower levels of vitality and higher ethical or moral distress (both, P <0.05). CONCLUSIONS: Sexual harassment is more common for women residents in Internal Medicine and Surgery programs. The adverse effects of sexual harassment on female residents detracts from an institution's professional workforce.

ABSTRACT

OBJECTIVE: To clarify our understanding of how the culture of residency training influences the well-being of residents, this study reports on the vitality of residents at 34 programs across the United States and identifies characteristics of the programs, institutions and residents that are associated with high resident vitality. DESIGN: In 2014 to 2015, residents nationally were surveyed using the validated C - Change Resident Survey. The survey assessed residents' vitality and 12 other dimensions that characterize residents' perspectives of the culture of the residency training programs: Self-efficacy, Institutional/program support, Relationships/inclusion/trust, Values alignment, Ethical/moral distress, Respect, Leadership aspirations, Mentoring, Work-life integration, Gender equity, Racial/ethnic minority equity, and self-assessed Competencies. Multilevel models were used to assess vitality within and across programs, and examine predictors including resident, program, and institution characteristics. PARTICIPANTS: Two thousand four hundred and fifty-two residents from 11 General Surgery, 12 Internal Medicine, and 11 Pediatrics programs at 14 U.S. academic health systems. RESULTS: One thousand seven hundred and eight residents responded (70% response rate). The mean Vitality score was 3.6 (range 1-5, where values of 4-5 represent high Vitality). There was wide variation among the 34 programs in the percent of residents who had high Vitality scores, ranging from 17% to 71%. However, the average Vitality scores within specialty (Surgery, Medicine, and Pediatrics) were not significantly different. The strongest predictors of Vitality were Work-life integration, Relationships/inclusion/trust, Institutional/program support, Res?>pect, Values alignment, and Ethical/moral distress, which together accounted for 50% of vitality variance. Individual demographics accounted for just 3% of variance. CONCLUSIONS: Vitality is an essential component of resident well-being, and within each specialty there are programs that have excelled in promoting a culture of high vitality. Our findings suggest that we should test interventions to enhance resident vitality by focusing greater attention on providing institutional support, aligning individual and institutional values, integrating work and personal life, and facilitating relationships, inclusiveness and trust.

ABSTRACT

BACKGROUND: A practical instrument is needed to reliably measure the clinical learning environment and professionalism for residents. OBJECTIVE: To develop and present evidence of validity of an instrument to assess the culture of residency programs and the clinical learning environment. DESIGN: During 2014-2015, we surveyed residents using the C - Change Resident Survey to assess residents' perceptions of the culture in their programs. PARTICIPANTS: Residents in all years of training in 34 programs in internal medicine, pediatrics, and general surgery in 14 geographically diverse public and private academic health systems. MAIN MEASURES: The C - Change Resident Survey assessed residents' perceptions of 13 dimensions of the culture: Vitality, Self-Efficacy, Institutional Support, Relationships/Inclusion, Values Alignment, Ethical/Moral Distress, Respect, Mentoring, Work-Life Integration, Gender Equity, Racial/Ethnic Minority Equity, and self-assessed Competencies. We measured the internal reliability of each of the 13 dimensions and evaluated response process, content validity, and construct-related evidence validity by assessing relationships predicted by our conceptual model and prior research. We also assessed whether the measurements were sensitive to differences in specialty and across institutions. KEY RESULTS: A total of 1708 residents completed the survey [internal medicine: n = 956, pediatrics: n = 411, general surgery: n = 311 (51% women; 16% underrepresented in medicine minority)], with a response rate of 70% (range across programs, 51-87%). Internal consistency of each dimension was high (Cronbach α: 0.73-0.90). The instrument was able to detect significant differences in the learning environment across programs and sites. Evidence of validity was supported by a good response process and the demonstration of several relationships predicted by our conceptual model. CONCLUSIONS: The C - Change Resident Survey assesses the clinical learning environment for residents, and we encourage further study of validity in different contexts. Results could be used to facilitate and monitor improvements in the clinical learning environment and resident well-being.

ABSTRACT

OBJECTIVE: A practical, reliable, and valid instrument is needed to measure the impact of the learning environment on medical students' well-being and educational experience and to meet medical school accreditation requirements. METHODS: From 2012 to 2015, medical students were surveyed at the end of their first, second, and third year of studies at four medical schools. The survey assessed students' perceptions of the following nine dimensions of the school culture: vitality, self-efficacy, institutional support, relationships/inclusion, values alignment, ethical/moral distress, work-life integration, gender equity, and ethnic minority equity. The internal reliability of each of the nine dimensions was measured. Construct validity was evaluated by assessing relationships predicted by our conceptual model and prior research. Assessment was made of whether the measurements were sensitive to differences over time and across institutions. RESULTS: Six hundred and eighty-six students completed the survey (49 % women; 9 % underrepresented minorities), with a response rate of 89 % (range over the student cohorts 72-100 %). Internal consistency of each dimension was high (Cronbach's α 0.71-0.86). The instrument was able to detect significant differences in the learning environment across institutions and over time. Construct validity was supported by demonstrating several relationships predicted by our conceptual model. CONCLUSIONS: The C-Change Medical Student Survey is a practical, reliable, and valid instrument for assessing the learning environment of medical students. Because it is sensitive to changes over time and differences across institution, results could potentially be used to facilitate and monitor improvements in the learning environment of medical students.

ABSTRACT

INTRODUCTION: Despite the well-recognized benefits of mentoring in academic medicine, there is a lack of clarity regarding what constitutes effective mentoring. We developed a tool to assess mentoring activities experienced by faculty and evaluated evidence for its validity. METHODS: The National Initiative on Gender, Culture, and Leadership in Medicine-"C-Change"-previously developed the C-Change Faculty Survey to assess the culture of academic medicine. After intensive review, we added six items representing six components of mentoring to the survey-receiving help with career and personal goals, learning skills, sponsorship, and resources. We tested the items in four academic health centers during 2013 to 2014. We estimated reliability of the new items and tested the correlation of the new items with a mentoring composite variable representing faculty mentoring experiences as positive, neutral, or inadequate and with other C-Change dimensions of culture. RESULTS: Among the 1520 responding faculty (response rate 61-63%), there was a positive association between each of the six mentoring activities and satisfaction with both the amount and quality of mentoring received. There was no difference by sex. Cronbach α coefficients ranged from 0.89 to 0.95 across subgroups of faculty (by sex, race, and principal roles). The mentoring responses were associated most closely with dimensions of Institutional Support (r = 0.58, P < .001), Institutional Change Efforts for Faculty Support (r = 0.52, P < .001), Values Alignment (r = 0.58, P < .001), Self-efficacy (r = 0.43; P < .001), and Relationships/Inclusion/Trust (r = 0.41; P < .001). DISCUSSION: Data demonstrated that the Mentoring scale is a valid instrument to assess mentoring. Survey results could facilitate mentoring program development and evaluation.

ABSTRACT

INTRODUCTION: The aims of this study were to (1) describe the quantity and quality of mentoring faculty in US academic health centers (AHCs), (2) measure associations between mentoring and 12 dimensions that reflect the culture of AHCs, and (3) assess whether mentoring predicts seriously contemplating leaving one's institution. METHODS: During 2007-2009, our National Initiative on Gender, Culture and Leadership in Medicine (C - Change) conducted a cross-sectional study of faculty from 26 representative AHCs in the United States using the 74-item C - Change Faculty Survey to assess relationships of faculty characteristics and various aspects of the institutional culture (52% response rate). Among the 2178 eligible respondents (assistant, associate, and full professors), we classified their mentoring experience as either inadequate, neutral, or positive. RESULTS: In this national sample, 43% of the 2178 respondents had inadequate mentoring; only 30% had a positive assessment of mentoring. There was no statistical difference by sex, minority status, or rank. Inadequate mentoring was most strongly associated with less institutional support, lower self-efficacy in career advancement, and lower scores on the trust/relationship/inclusion scale. The percent of faculty who had seriously considered leaving their institution was highest among those who had inadequate mentoring (58%), compared to those who were neutral (28%) or had positive mentoring (14%) (all paired comparisons, p < .001). DISCUSSION: In a national survey of faculty of US AHCs, mentoring was frequently inadequate and this was associated with faculty contemplating leaving their institutions. Positive mentoring, although less prevalent, was associated with many other positive dimensions of AHCs.

ABSTRACT

PURPOSE: Faculty with high vitality are essential to the missions of academic health centers (AHCs). Because little is known about how to measure or enhance faculty vitality, the authors assessed current faculty vitality and identified its predictors. METHOD: In a stratified random sample of 26 nationally representative U.S. AHCs, the authors surveyed 4,578 full-time faculty during 2007-2009. The validated survey measured detailed faculty perceptions of their professional experiences and organizational culture. Vitality was measured with a previously evaluated five-item scale. RESULTS: Of the faculty invited, 2,381 (52%) responded, with 2,218 eligible for analysis. Respondents included 512 (23%) underrepresented in medicine minority (URMM) faculty and 1,172 (53%) women. In a multivariable model including individual- and AHC-level factors, the strongest predictors of vitality were faculty members' perceptions of four dimensions of AHC culture: Relationships/inclusion, Values alignment, Work-life integration, and Institutional support (all P < .001). Weaker predictors were faculty age, institution type (public/private), and the AHC's National Institutes of Health funding rank (all P ≤ .03). Half of the respondents scored high on vitality, whereas 25% had low, or suboptimal, scores. Holding perceptions of culture constant, neither female nor URMM faculty had vitality scores that were different on average from male or nonminority faculty. CONCLUSIONS: A large percentage of faculty lack the vitality essential to meeting the AHC missions of discovery, education, and patient care. Enhancing faculty vitality, and AHC resilience, requires more attention to strengthening relationships, improving the misalignment between faculty and institutional values, and improving work-life integration.

ABSTRACT

PURPOSE: A diverse medical school faculty is critical to preparing physicians to provide quality care to an increasingly diverse nation. The authors sought to compare experiences of underrepresented in medicine minority (URMM) faculty with those of non-URMM faculty in a nationally representative sample of medical schools. METHOD: In 2007-2009, the authors surveyed a stratified random sample of 4,578 MD and PhD full-time faculty from 26 U.S. medical schools. Multiple regression models were used to test for differences between URMM and other faculty on 12 dimensions of academic culture. Weights were used to adjust for oversampling of URMM and female faculty. RESULTS: The response rate was 52%, or 2,381 faculty. The analytic sample was 2,218 faculty: 512 (23%) were URMM, and 1,172 (53%) were female, mean age 49 years. Compared with non-URMM faculty, URMM faculty endorsed higher leadership aspirations but reported lower perceptions of relationships/inclusion, gave their institutions lower scores on URMM equity and institutional efforts to improve diversity, and more frequently engaged in disparities research. Twenty-two percent (115) had experienced racial/ethnic discrimination. For both values alignment and institutional change for diversity, URMM faculty at two institutions with high proportions (over 50%) of URMM faculty rated these characteristics significantly higher than their counterparts at traditional institutions. CONCLUSIONS: Encouragingly, for most aspects of academic medicine, the experiences of URMM and non-URMM faculty are similar, but the differences raise important concerns. The combination of higher leadership aspirations with lower feelings of inclusion and relationships might lead to discouragement with academic medicine.

ABSTRACT

BACKGROUND: Energized and productive faculty are critical to academic medicine, yet studies indicate a lack of advancement and senior roles for women. OBJECTIVE: Using measures of key aspects of the culture of academic medicine, this study sought to identify similarity and dissimilarity between perceptions of the culture by male and female faculty. DESIGN: The C - Change Faculty Survey was used to collect data on perceptions of organizational culture. PARTICIPANTS: A stratified random sample of 4,578 full-time faculty at 26 nationally representative US medical colleges (response rate 52 %). 1,271 (53 %) of respondents were female. MAIN MEASURES: Factor analysis assisted in the creation of scales assessing dimensions of the culture, which served as the key outcomes. Regression analysis identified gender differences while controlling for other demographic characteristics. KEY RESULTS: Compared with men, female faculty reported a lower sense of belonging and relationships within the workplace (T = -3.30, p < 0.01). Self-efficacy for career advancement was lower in women (T = -4.73, p < 0.001). Women perceived lower gender equity (T = -19.82, p < 0.001), and were less likely to believe their institutions were making changes to address diversity goals (T = -9.70, p < 0.001). Women were less likely than men to perceive their institution as family-friendly (T = -4.06, p < 0.001), and women reported less congruence between their own values and those of their institutions (T = -2.06, p < 0.05). Women and men did not differ significantly on levels of engagement, leadership aspirations, feelings of ethical/moral distress, perception of institutional commitment to faculty advancement, or perception of institutional change efforts to improve support for faculty. CONCLUSIONS: Faculty men and women are equally engaged in their work and share similar leadership aspirations. However, medical schools have failed to create and sustain an environment where women feel fully accepted and supported to succeed; how can we ensure that medical schools are fully using the talent pool of a third of its faculty?

ABSTRACT

PURPOSE: Vital, productive faculty are critical to academic medicine, yet studies indicate high dissatisfaction and attrition. The authors sought to identify key personal and cultural factors associated with intentions to leave one's institution and/or academic medicine. METHOD: From 2007 through early 2009, the authors surveyed a stratified random sample of 4,578 full-time faculty from 26 representative U.S. medical schools. The survey asked about advancement, engagement, relationships, diversity and equity, leadership, institutional values and practices, and work-life integration. A two-level, multinomial logit model was used to predict leaving intentions. RESULTS: A total of 2,381 faculty responded (52%); 1,994 provided complete data for analysis. Of these, 1,062 (53%) were female and 475 (24%) were underrepresented minorities in medicine. Faculty valued their work, but 273 (14%) had seriously considered leaving their own institution during the prior year and 421 (21%) had considered leaving academic medicine altogether because of dissatisfaction; an additional 109 (5%) cited personal/family issues and 49 (2%) retirement as reasons to leave. Negative perceptions of the culture-unrelatedness, feeling moral distress at work, and lack of engagement-were associated with leaving for dissatisfaction. Other significant predictors were perceptions of values incongruence, low institutional support, and low self-efficacy. Institutional characteristics and personal variables (e.g., gender) were not predictive. CONCLUSIONS: Findings suggest that academic medicine does not support relatedness and a moral culture for many faculty. If these issues are not addressed, academic health centers may find themselves with dissatisfied faculty looking to go elsewhere.
