Psychological predictors of medical residents' perspectives on shared decision-making with patients: a...

Shared Decision Making (SDM) is as ideal model for resident-patient relationship which may improve medical outcomes. Nevertheless, predictive psychological factors influencing residents' perspective regarding SDM are unclear. The current study investigated the relationship between two psychological factors, mental health and personality traits, and residents' views toward SDM.

In a cross-sectional study, 168 medical residents of the Babol University of Medical Sciences studying in 13 field specialties were recruited. The residents completed three questionnaires including Shared Decision-Making Questionnaire (SDM-Q-Doc, physician version), General Health Questionnaire (GHQ-12), and Big Five Personality (NEO-FFI).

Residents had an overall agreement of about 88% regarding SDM with patients. There was no significant difference between male and female residents in terms of the degree of agreement for SDM. Concerning SDM, there was no significant relationship either between residents' views and neuroticism, extraversion, agreeableness, and conscientiousness. In multivariate regression, mental health did not predict the SDM, but openness to experience negatively predicted residents' views concerning SDM (β = - 0.388, p < 0.001).

The residents' personality trait of openness to experience was a significant negative predictor of SDM with patients. A better understanding of how psychological factors relate to residents' perspectives may help clinicians properly discuss the treatment options with the patient thereby encouraging them for SDM or to consider their own preferences.
