Exploration of mental health of health students: Dental and medical formations promote anhedonia.

OBJECTIVES: Health students usually report to experience stress during their formation. This is due to their exposure to patient's disease or death, to their learning of interpersonal relationships, and to the discovery of health practitioner's responsibility. Anhedonia represents a deficit in experiencing pleasure that is promoted by stressful living conditions. We hypothesized that health formations promote anhedonia. Our objectives have consisted in measuring anhedonia and analyzing its variation and heterogeneity among health students.

METHODS: The Temporal Experience of Pleasure Scale (TEPS) was used to assess anhedonia and its anticipatory and consummatory dimensions. TEPS corresponds to an 18-item questionnaire, the score of which is based on a 6-point Likert scale. Low score indicates a high anhedonia propensity. Score differences were analyzed by considering gender, curriculum and formation as independent variables. A cluster analysis was used to explore anhedonia heterogeneity among our sample.

RESULTS: We collected 1231 responses. Our data confirm French TEPS as a reliable tool for anhedonia evaluation in dental and medical students. Statistical analyses reveal a significant effect of gender (male>female), curriculum (clinical>preclinical) and formation (dental>medical) on anhedonia propensity. Cluster analysis highlights four sub-groups of students characterized by increasing anhedonia traits and by different gender, formation and curriculum proportions.

CONCLUSION: This work describes the first analysis of anhedonia manifestation during dental and medical studies in France. The consequences of our findings for the comprehension of dental and medical students' mental health during their formation are discussed.
