As baseline assessments (T0), participants will complete the Maslach Burnout Inventory (MBI) and 5-day clinical situation recordings (measuring supervisee's reflexivity) in which they describe a clinical situation that has remained in their mind during the day.

Each participant will then take part in four 60 min clinician-centred supervision sessions (bi-monthly supervisions). During each supervision, (i) clinicians' feelings toward the patients presented will be measured with the Feeling Word Checklist (FWC-58) at the beginning and end of each session, and (ii) specific aspect and the overall quality of the supervision wil be assessed with a 4-item ad-hoc questionnaire for both supervisee and the supervisor.

Assessments performed at T0 will be repeated after the 2-month intervention (T1). Finally, the MBI will be administered at follow-up assessments 3 months (FU3) and 6 months (FU6) after T1.

As baseline assessments (T0), participants will complete the Maslach Burnout Inventory (MBI) and 5-day clinical situation recordings (measuring supervisee's reflexivity). The clinical situation recordings consist of describing a clinical situation that has remained in the clinician's mind during the day.

They will then not receive supervisions during the 2-month waiting period.

Assessments will be repeated after the 2-month waiting period (T1: MBI and 5-day clinical situation recordings) and follow-up evaluations with the MBI will take place at 3 months (FU3) and 6 months (FU6).

After the trial period (i.e., after FU6), participants in this arm will be offered the opportunity to reveice the intervention.

In the first and thrid sessions, supervisees will comprehensively describe a clinical situation with a patient, which strongly affected them in a very negative way (e.g., feelings of rejection, anxiety, anger), or even lead to words (e.g., outbursts, impoliteness, cynicism) and actions (e.g., avoidance of the patient, forgetting appointments, deviation from good medical practice).

In the second and fourth sessions, the same proceeding takes place, with the exception that participants are invited to present a clinical encounter with a patient, which strongly affected them in a very positive way (e.g., feelings of intense closeness, sympathy, pronounced mourning after the patient's death), or even lead to words (e.g., self-disclosure, discussing private information, compliments) and actions (e.g., special favours, difficulties to end treatment, deviation from good medical practice).

Reflexivity will be assessed with the reflexivity indicator, a 4-level framework for classifying clinicians' narratives identified in the 5-day clinical situation recordings. This indicator has been developped in a previous study (in preparation) with the following level:

• Level 0 - Describing: clinicians report medical and basic psychosocial facts, like a referral note.
• Level 1 - Noticing: they mention interactions and resonate with patients' emotions but without deeper links.
• Level 2 - Recognizing: they reflect on their interaction style, noting institutional/professional influences, and ask "what if I could do this consultation again?" to improve future practice.
• Level 3 - Making sense: they analyze what happened, what could have been done differently, and what to do next time. Here, clinicians derive general principles, extending insights beyond the single case and shifting perspective.

For the SPV group only, clinicians' feelings towards presented patients will be measured with the Feeling Word Checklist (FWC; 58 items), a self-report questionnaire, prior and immediately after each supervison session. Clinicians are invited to indicate if and to what extent (5 point rating scale with 0 = not at all, and 4 = very much) the feeling described through the words are experienced regarding a given patient. We will use a translated version (french version) of the FWC.
