Previous research has examined the experiences of voluntary, community, and social enterprise (VCSE) group providers, but the voices of group users, especially those recovering from, or living with SMI, are sparse. This study addresses that gap, using the COVID-19 pandemic lockdown as a natural experiment to gain insights into the experiences of individuals participating in VCSE-run creative and social groups, and comparing this with the experiences of providers. We conducted photo-elicitation focus groups to explore group members’ perspectives. Lockdown highlighted to group members what they valued most, and therefore what they missed about attending groups. Participants reflected on how significant their group was to their experiences of social connectedness and belonging. Group members’ experiences differed significantly from providers’ experiences of delivering online groups during lockdown. In some cases lockdown exacerbated existing challenges for marginalized individuals, highlighting the critical importance of compassionate, skilled, and well-informed group leadership. The needs of marginalized populations and the risk that these may be overshadowed by other public health priorities were highlighted. Our findings underline the urgency of developing inclusive policies and practices that prioritize voices of marginalized groups. By listening to these voices, policymakers and group leaders can create fairer and more responsive support systems.
