Does Personality Matter? Perceptions and Experiences of Introverts and Extraverts as General Surgeons.

PHENOMENON: Medical educators increasingly recognize both the challenges introverts, compared to extraverts, may face in medical training and the unique strengths they bring to practice. However, few researchers have examined in-depth how introverts and extraverts truly experience training and practice, particularly in specialties like surgery that tend to value qualities (e.g., dominance and assertiveness) typically associated with extraverts. This study aimed to explore the perceptions and experiences of individuals with both personalities within the field of general surgery. APPROACH: Using a constructivist grounded theory approach, six general surgeons and 10 general surgery residents who identified as introverted, extraverted, or ambiverted were recruited from two Canadian tertiary care hospitals to participate in semi-structured interviews. Data collection and analysis occurred iteratively, and data were analyzed using open, selective, and thematic coding. Constant comparison allowed us to make sense of the similar and dissimilar views that emerged from each interview. FINDINGS: Irrespective of their personalities, participants voiced two general patterns of responses. Some participants believed that "personality doesn't matter": that both introverted and extraverted practice styles were equally viable and neither introverts nor extraverts would find surgical training more challenging than the other (culture of equality). However, others believed that "personality matters," emphasizing that surgeons should be dominant and aggressive leaders. Only those who believed "personality matters" felt that introverts sometimes needed to act more extraverted in order to succeed in surgical training (culture of hierarchy). Similar numbers of introverts and extraverts adhered to each viewpoint. INSIGHTS: Our qualitative approach allowed us to draw meaning from the complex subjective experiences of our research participants. Our findings suggest that two competing cultures (equality and hierarchy) co-exist within the field of surgery and that trainees, depending on which culture they adhere most to, will or will not "adapt" their personalities to the workplace. These findings deepen our understanding of the nuances of surgical culture and have important implications for how we select candidates based on personality.

Exercise is Medicine Canada physical activity counselling and exercise prescription training improves counselling, prescription, and referral practices among physicians across Canada.

Exercise is Medicine Canada (EIMC) is an initiative that promotes physical activity (PA) counselling and exercise prescription within health care. The purpose of this study was to compare physicians' perceptions and practices around PA counselling and exercise prescription following EIMC training. Physicians (n = 46) from 7 different provinces completed questionnaires initially and 3 months following an EIMC workshop. Three months after intervention, physicians reported greater confidence compared with baseline for providing physical activity and exercise (PAE) information to patients (79% vs 55%; p < 0.001), assessing patients' PAE (69% vs 44%, p = 0.005), answering patients' PAE questions (78% vs 54%, p < 0.001), providing PAE advice (71% vs 43%, p < 0.001), and identifying which patients would benefit from referral to qualified exercise professionals (77% vs 52%, p = 0.002). At follow-up, physicians reported PA prescription barriers as less impactful (out of 4; all p < 0.05), including perceived patients' lack of interest (2.75 to 2.25), lack of available resources (2.59 to 2.00), and lack of time (2.41 to 2.14). The proportion of physicians providing written exercise prescriptions increased from 20% to 74%. This study suggests that the completion of a 1-day EIMC workshop increases physicians' confidence, knowledge, and counselling behaviours of physicians in prescribing PAE.

Physical activity and nutrition among youth in rural, suburban and urban neighbourhood types.

OBJECTIVES: Physical activity and nutrition are essential to healthy living and particularly important during youth, when growth and development are key. This study examined rates of physical activity (PA) and diet quality (DQ) among youth in grades 7 to 9 in Halifax, Nova Scotia, during the 2008/09 school year and tested differences among students in rural, urban and suburban neighbourhood types of high and low socio-economic status (SES). METHODS: Youth in grades 7 through 9 (aged 12-16; 53% male) from six schools (N=380), stratified by neighbourhood type (urban, suburban, rural) and SES, wore accelerometers for up to 7 days (mean=4.14, standard deviation=1.49) and completed a nutritional survey. RESULTS: The findings suggest important differences in PA and DQ across SES and neighbourhood type. Specifically, rates of moderate to vigorous physical activity among youth from schools in lower socio-economic areas were higher in urban than in suburban or rural settings. Furthermore, DQ was better among youth in higher than in lower socio-economic urban settings. CONCLUSIONS: Understanding these differences in PA and DQ across rural, urban and suburban environments of high and low SES may highlight subgroups and targeted geographic areas for the design of interventions to improve rates of PA and health nutrition.
