This intervention consists of an individual, in-person session in which each participant engages in a 10-minute transformative Virtual Reality (VR) experience entitled "The River and the Leaf", delivered through the Meta Quest 3 headset. Drawing on Acceptance and Commitment Therapy (ACT) metaphors, participants are guided to reflect on key aspects of the experience, their professional challenges, and the personal resources available to them. Following the VR session, participants are supported in clarifying the values that guide their everyday actions. After the in-person session, all participants are encouraged to identify and implement committed actions aligned with their values over the subsequent two weeks, supported by two dedicated audio tracks.

This self-report scale was developed by Francis et al. (2016; Giovannetti et al., 2022) to measure psychological flexibility. The scale consists of 23 items, which can be answered using a 6-point Likert scale, where 0 indicates "completely disagree" and 6 "completely agree." The questionnaire is divided into three subscales: Openness to Experience (OE), Behavioral Awareness (BA), and Valued Action (VA), which correspond to the three pillars of psychological flexibility. Higher scores on the CompACT indicate greater psychological flexibility.

This self-report scale was developed by Keyes (2002; Petrillo et al., 2015) to measure emotional, social, and psychological well-being. The scale consists of 14 items, which can be answered using a 6-point Likert scale, where 0 indicates "never" and 5 "every day." To assess the three dimensions, the questionnaire is divided into three subscales: the Emotional Well-Being scale (EWB, items 1-3), the Social Well-Being scale (SWB, items 4-8), and the Psychological Well-Being scale (PWB, items 9-14). Higher scores on the MHC-SF indicate greater well-being.

This scale aims to measure the intensity of positive and negative emotions (joy, contentment, pride, love, compassion, awe, hope, gratitude, sadness, fear, anger, admiration, inspiration, and awe) (Shiota et al., 2006; Cloos et al., 2023). The intensity can be expressed using a Likert scale, where 0 corresponds to "not at all" and 10 to "very much."

This self-report scale was developed by Usoh et al. (2000) to assess the user's sense of presence in the virtual environment. The instrument consists of 6 items, which are rated on a 7-point Likert scale. Higher scores on the SUS indicate a greater sense of presence.
