BACKGROUND: Young Black and Latinx Gay and Bisexual Men and Transgender Women (YBLGBMTW) face high levels of mental health related concerns. While online interventions show promise for addressing mental health conditions, few models focus on this population. METHODS: We used a pre-post design to assess the feasibility and acceptability of a peer delivered mental health awareness intervention for YBLGBMTW. This study was nested as the control arm from a larger study investigating if Peer Influencers (PIs) can improve HIV prevention. PIs helped develop an online outreach campaign to raise awareness of pertinent mental health topics as chosen by the PIs. PIs recruited YBLGBMTW participants from online social networks, posted contents over a six-week period, and participants completed baseline and post-intervention surveys. RESULTS: PIs successfully recruited 71 participants of whom 92% completed the six-week post-intervention survey. Participants had on average 6.7 engagements with posted contents and 82% of participants indicated being very satisfied with the intervention. CONCLUSION: Using an intervention informed and delivered by PIs, participants were presented with information to address relevant mental health concerns. We found that such novel means of engaging this sample for mental health is feasible, acceptable, and merits further development.
