Beyond skills: The impact of personality traits, empathy and stress mindset on OSCE outcomes

Objective Structured Clinical Examinations (OSCEs) are widely used to assess medical students clinical skills, including non-technical abilities such as communication and empathy. However, the potential influence of individual psychological traits--such as personality dimensions, empathy, and stress-related mindset--on OSCE performance remains understudied. This study investigated associations between personality traits, empathy levels, stress mindsets, and performance in OSCEs among medical students. An online questionnaire (including the Big Five Personality Traits Inventory 2, the Jefferson Scale of Physician Empathy (Medical Student version), the Growth Mindset Scale, the Stress Mindset Measure) was provided to all fifth-year medical students enrolled at the Universite Paris Cite for six weeks before undertaking graduation summative OSCEs. Their scores were correlated with OSCE performance using Spearmans correlation and linear regression analyses. A total of 99 questionnaires were included and analysed. None of the psychometric tests we assessed showed a significant correlation with OSCE scores. The strongest predictors of success in OSCEs were higher scores in written examinations, previous OSCE performance, and being female. In non-interactive OSCE stations, conscientiousness was the only significant predictor, with a positive association (p=0.001). Neuroticism was positively associated with performance improvement between OSCE sessions (p=0.042). Personality traits, self-reported empathy, and stress-related mindsets do not predict success in OSCEs as isolated traits. Further research is needed to determine whether it holds true for all kinds of OSCEs. Multidimensional psychometric assessment may be relevant when investigating performance outcomes in OSCEs.
