Medical students are subjected to a high competitive pressure throughout their curriculum. High levels of stress are associated with a deterioration in quality of life and learning abilities. Our field surveys conducted in 2022 and 2023 at the Lyon Est Medical School revealed that second-cycle students presented a high level of stress. It is expected that these feelings significantly degrade their quality of life as well as their health. Furthermore, a local survey reported that one in two medical students had experienced at least one depressive episode, and one in three had already had suicidal thoughts during their curriculum. Thus, it would become crucial for medical students to manage stressful situations and reduce stress levels during their studies. The PROMESS - STRESS project aims to offer solutions to students to reduce their stress levels during their medical studies. It responds to a demand expressed by students : our previous field study showed that 45% of fourth-year students declared being "very interested" and/or "interested" in following a intervention aimed at stress reduction. An early knowledge of stress remediation tools would allow students to quickly acquire the necessary tools to cope with stressful situations they will encounter during their training and their life as future physicians. The objective of this study is to determine the influence of a stress management intervention on medical students levels of psychophysiological stress and satisfaction.
Our project aims to support future healthcare professionals to adopt health-promoting behaviors during their studies in a preventive approach. This support will be provided through an intervention of stress management during their curriculum. Specifically, 4th and 5th-year students of the Faculty of Medicine of Lyon Est will have the opportunity to participate in the PROMESS STRESS project. 45 voluntaries will follow a preventive program based on stress management. This intervention will span 11 weeks. At the end of this period, we expect improvements in both subjective and objective indicators of stress. METHODS. PRE-INTERVENTION. Week 1. Participants will undergo a two-hour session, during which, they will complete questionnaires on stress. We will also record Heart Rate Variability (HRV). INTERVENTION. From week 5 to week 11. The stress management intervention will consist of three individual sessions, each lasting one hour, with approximately 15 days between each session. Each session includes individual interviews between a stress expert and the participant (i.e. student). The sessions will be scheduled as follow: week 5 and 6 (session 1), week 7 and 8 (session 2), week 9, 10, and 11 (session 3). During the interview, the expert realizes an initial assessment of student stress levels and gives personalized goals to student. Subsequent sessions follow the same structure.

RECRUITINGPerceived level of stress : Evolution of the score obtained at the Perceived Stress Scale (PSS).
The students level of stress will be assessed through the PSS questionnaire ranging from 0 (none) to 40 (extreme). One score is assessed and can be classified as low, moderate and elevated stress. The measure will be done every session, i.e. session 1 (week 5-6), session 2 (week 7-8) and session 3 (week 9,10,11).
Time frame: From week 5 to week 11.
Scale of Holmes and Rahe : score obtained at the Holmes and Rahe Questionnaire Inventory.
Quantity of stressors met by the students during the last years. One score is assessed and can be classified as low, medium and high risk of health degradation. This measure will be done during the pre-interventional period at week 1.
Time frame: Week 1 (Pre-intervention).
Big-5 : scores obtained at the Big-5 questionnaire.
The students personality traits (i.e. agreeableness, openness, consciousness, extraversion, neuroticism) will be assessed through the questionnaire each score ranges from one to five. This measure will be done during the pre-interventional period at week 1.
Time frame: Week 1 (Pre-intervention).
Coping strategies : scores obtained at the Brief Cope Inventory (BCI).
The students coping strategies (social support, active resolution, positive thinking, and avoidance) will be assessed through the BCI questionnaire, each score ranging from 1 to 4; a high score indicating that the behaviour was highly engaged. This measure will be done during the pre-interventional period at week 1.
Time frame: Week 1 (Pre-intervention).
Perceived level of stress : score obtained at the Perceived Stress Scale
The students level of stress will be assessed through the PSS questionnaire ranging from 0 (none) to 40 (extreme). One score is assessed and can be classified as low, moderate and elevated stress.This measure will be done during the pre-interventional period at week 1.
Time frame: Week 1 (Pre-intervention).
Heart rate variability (HRV) marker: cardiac coherence score during the pre-intervention.
The students basal level of physiological stress will be assessed through the cardiac coherence score, an HRV marker. This measure will be done during the pre-interventional period at week 1.
Time frame: Week 1 (Pre-intervention).
Heart rate variability (HRV) marker: SDNN during the pre-intervention.
The students basal level of physiological stress will be assessed through the SDNN score, an HRV marker. SDNN is the standard deviation of the inter-beat-intervals (IBI) measured in ms, NN means "normal" beats, i.e, removing abnormal or false beats. This measure will be done during the pre-interventional period at week 1.
Time frame: Week 1 (Pre-intervention).
Heart rate variability (HRV) marker: RMSSD during the pre-intervention.

Time frame: Week 1 (Pre-intervention).
Heart rate variability (HRV) marker: Low frequency / High frequency ratio (LF/HF) during the pre-intervention.
The students basal level of physiological stress will be assessed through the LF/HF ratio, an HRV marker. HF. The HF band is typically correlated with RMSSD and NN50, lower HF power is associated with stress and anxiety. It is primarily associated with activity in the parasympathetic nervous system. LF. The LF band is typically associated with the sympathetic nervous system and the HF/LF ratio is often used as a measure of sympathetic-parasympathetic balance in the nervous system. This measure will be done during the pre-interventional period at week 1.
Time frame: Week 1 (Pre-intervention).
Heart rate variability (HRV) marker: pnn50% during the pre-intervention.
The students basal level of physiological stress will be assessed through the pnn50%, an HRV marker. NN50 is the Number of pairs of successive intervals that differ by greater than 50ms.
