Participants will attend three 90-minute Virtual self-help sessions, hosted on Zoom. Sessions will be held at the same time each week for three weeks, in parallel to the experimental condition. First, the co-facilitator will let participants into the Zoom room and begin the recording. After they introduce themselves, they will remain on mute/camera off for the entire meeting to handle technical difficulties or intervene when violations occur, for example, using inappropriate language. Co-facilitators may also interact with participants through the chat to provide referrals. Then, the discussion leader will explain their role and ask everyone to introduce themselves. As a group, they will set some ground rules. Then, the discussion leaders will guide the discussion, using the Self-Help Session Manual as a reference, which provides structure and reference questions to facilitate discussion. Beyond this guideline, participants can discuss anything they decide as a group.
