IntroductionBurnout, depression, and anxiety are major concerns among physicians because they affect individual well-being, patient care, and healthcare systems. Neurodevelopmental traits, including autistic-like traits (ALTs) and attention-deficit/hyperactivity disorder (ADHD)-like traits (ADHLTs), may increase vulnerability to psychological distress. However, little is known about how these traits relate to burnout, depression and anxiety, and empathy among junior residents.MethodsIn this cross-sectional study, 148 junior residents from two teaching hospitals in Japan completed validated measures of ALTs (21-item Japanese version of the Autism-Spectrum Quotient), ADHLTs (Adult ADHD Self-Report Scale Screener), burnout (Maslach Burnout Inventory), depression and anxiety (Hospital Anxiety and Depression Scale), physician–patient empathy (Jefferson Scale of Physician Empathy), and psychological flexibility and inflexibility processes (Valuing Questionnaire, Cognitive Fusion Questionnaire-7, and Work-related Acceptance and Action Questionnaire). Associations were examined using multivariable logistic and linear regression analyses. Exploratory statistical mediation analyses using structural equation modeling examined indirect associations through psychological flexibility and inflexibility processes.ResultsThe prevalence of ALTs and ADHLTs was 23.6% for each trait. ALTs were associated with lower personal accomplishment, a burnout dimension; higher depression and anxiety; and lower physician–patient empathy. ADHLTs were associated with greater emotional exhaustion, another burnout dimension. In exploratory statistical mediation analyses, progress toward values, a core process of psychological flexibility, showed a significant indirect association between ALTs and personal accomplishment, and the direct association was attenuated and no longer statistically significant after including the process variables. Significant indirect associations through progress toward values were also observed for the associations of ALT with depression and anxiety and empathy. Cognitive fusion, a core process of psychological inflexibility, showed a significant indirect association between ADHLTs and emotional exhaustion. Overall, neurodevelopmental traits were associated with distinct patterns of psychological functioning, suggesting variability in both vulnerability and adaptive processes.DiscussionNeurodevelopmental traits such as ALTs and ADHLTs were significantly associated with burnout dimensions, depression and anxiety, and physician–patient empathy among junior residents. Psychological flexibility and inflexibility processes, particularly progress toward values and cognitive fusion, may be relevant to these associations. Process-based support strategies may warrant further investigation for residents with elevated neurodevelopmental traits.Clinical trial registrationhttps://center6.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R00005, identifier UMIN000046897.
