Risk and protective factors against burnout increase during psychiatry training: evidence from a longitudinal multicentre controlled study

Background Mentalising skills may be conceptualised as composed by both personal and interpersonal competencies, in turn shaped by early adverse experiences and coping strategies. Although cross-sectional observations described a role for mentalising skills in burnout development, large-scale longitudinal studies on the topic remain limited, especially in relation to psychiatry training. Aims The primary aim was to investigate protective and risk factors for higher burnout scores across time. Secondary aims included testing whether psychiatry exhibited different burnout scores across time in comparison to other medical residents. Method A cohort of 1803 medical residents (1131 psychiatry residents) was assessed for mentalising skills, conceptualised as composed of emotional regulation (Difficulties in Emotion Regulation Scale), interpersonal competencies (Interpersonal Competence Questionnaire), coping strategies (Coping Orientation to Problems Experienced) and burnout dimensions (Maslach Burnout Inventory). One-year follow-up was available for 520 psychiatry residents (73.03% response rate) and 234 other medical residents (35.94% response rate). Longitudinal mixed models and bivariate latent change models were employed. Results Across all residents, greater levels of burnout were associated with higher scores in insecure attachment, emotional dysregulation and maladaptive coping, as well as lower scores in interpersonal skills. Attending at least one supervision per month was associated with lower burnout scores across time. According to a bivariate latent change model, emotional regulation improvements through years were associated with lower burnout scores across time. In psychiatry residents, lower burnout scores across time were observed as compared to other medical residents. Psychiatry residents benefited from a higher protective effect of interpersonal competencies (group by moderator by time interaction) and coping strategies against burnout. Conclusions Mentalising skills may mitigate burnout development. Training in psychiatry emerged as a potential mitigating factor against burnout increases. Structured supervisions may foster professional development and emotional resilience.
