You are invited to participate in a research study involving a new program designed to support people with navigating the changes that can happen after difficult life events. The program activities are aimed at helping you move forward and raise your well-being after experiencing one of life's challenges. This study should not be considered an alternative to any treatment or medication for any disorder or problem.

Adversity is an inevitable part of human life and can potentially lead to great suffering. However, facing life's challenges also presents the opportunity for lasting and meaningful change. This phenomenon is referred to as posttraumatic growth (PTG) and has been defined as "positive psychological change experienced as the result of the struggle with highly challenging life circumstances" (Tedeschi & Calhoun, 2004). There are several existing psychosocial interventions (e.g., expressive writing) that have been shown to promote PTG, despite not being intentionally designed to do so. Additionally, there have been several interventions developed more recently that specifically target the cultivation of PTG, although many of them have not been extensively tested (Dolbier, Jaggars, & Steinhardt, 2010; Shakespeare-Finch et al., 2014). SecondStory 2.0 is an online group-format intervention that was augmented from the original program (SecondStory) which was designed to promote PTG and well-being in the face of adversity. SecondStory 2.0 incorporates narratives of moral exemplars who have overcome adversity, drawing from recent philosophical explorations that have highlighted the pedagogical functions of such exemplars (e.g. Zagzebski, 2017). This research has focused on their potential to model virtues that consistently characterize individuals who have overcome adversity (e.g. strength, vulnerability, wisdom, love, trust) (Brady, 2018). By including experiences of adversity in these exemplarist narratives, we can theoretically increase an individual's admiration for the exemplar, and in turn enable effective emulation while also broadening his/her understanding of the moral foundations of the human condition (Kidd, 2018).

This study will take place remotely via phone and zoom. The initial interview/screening will take place via an online Qualtrics survey (follow-up by phone with the study coordinator), and the intervention sessions will be held online via Zoom with our trained intervention facilitators (licensed therapists). We will also be providing intervention support via a text messaging platform called Mobile Coach. The messages will be the same for all of the participants, and they will all receive them at the same time point in the program. All of the questionnaires will be completed online via a link that will be texted and/or emailed to the participant. Once participants see an advertisement and reach out to our study coordinator about their interest in the study, they will be directed to complete an online prescreening survey via Qualtrics to assess their eligibility for study participation. The study coordinator will then review the online survey and complete the cognitive screener and mental health questions by phone. If participants are eligible after the phone screen with the study coordinator, they will be scheduled to do a safety assessment via phone with one of our study clinicians. Once participants are deemed eligible, they will complete the consent form and be randomized into one of two conditions: active program or control. If a participant is randomized into the control condition, they will be placed on a "wait list" to receive the intervention at a later date. If a participant is randomized into the active program condition, they will be given the schedule for the group sessions, and sent a Zoom link for participation. The group intervention sessions will be guided by our trained facilitators for 75-90 minutes weekly for six weeks. After week 6, participants who were in the active program group will be asked complete a feedback form, as well as to take part in a semi-structured group interview to determine the acceptability and feasibility of the program. They will then enter the follow-up period of the study. Regardless of condition, participants will complete a set of questionnaires at Weeks 0, 3, 6, 9, and 12.

After week 12, participants who were randomized to the control condition will receive access to a recorded version of the intervention online. The recorded version will include the intervention developer talking through the intervention content and materials on video. No study participants will be included in this video.

This data will help to inform us whether the new improvements made to the SecondStory protocol are effective in improving participants' overall well-being and response to trauma, and will guide any future changes made to the intervention protocol.
