Protocol of the intervention.

Session Element	Time	Goals	Supporting Document
1 Introduction to the adventure and bonding	1 to 2 sessions	Creating a bond between participants and introducing the campaign setting, alongside with rules and the scope of the narrative.	Mental health screening scales (GAD-7, PHq-9, AUDIT, IHS-2 and ASRS-18), introduction to the players journal and first assignments.
2 Introduction to the first therapeutic narrative objective and conflict building	4 to 5 sessions	Based on results from the mental health screening scales, a narrative will be selected to match the therapeutic needs of the group. In these sessions the group will be presented with said conflict and will have to work as a group towards a resolution.	The player’s journal will be utilized to record and review the player’s perceptions and inputs regarding the proposed challenges. Additionally, the journal will serve as an emotional log, allowing players to document how various situations made them feel during and after the session.
3 Feedback collection and role-play intermission	1 to 2 sessions	These sessions are designed to encourage players to reflect on the challenges they have just completed, reviewing their choices and behaviors. The Guide should introduce a character to facilitate role-play discussions, extracting insights into each player character’s thought process and understanding which information each one deemed most important to achieve the proposed objective.	The players’ journals will contain a feedback sheet where players can highlight scenes or conflicts that affected them beyond the session setting. They can also indicate if they regret any course of action and suggest how that action could be undone or if there were any alternatives. This feedback sheet will also enable players to speculate on the consequences of their actions in the narrative setting.
4 Closing remarks and Follow-up	1 to 2 sessions	These sessions will conclude the narrative path chosen by The Guide at the beginning of the intervention, providing closure to the individual stories of the characters as well as an ending to the overall narrative. Players will be asked to provide background for their characters’ ending, expressing their goals and wishes and explaining why they chose them for the character.	The players will then complete the mental health screening scales again for post-intervention data collection and submit their player’s journals.
