Feasibility, acceptability and preliminary effectiveness of a community-based group psychosocial support model for conflict survivors in Colombia: An assessment of in-person and remote intervention modalities during the COVID-19 pandemic.

Background: Community-based psychosocial support (CB-PSS) interventions utilizing task sharing and varied (in-person, remote) modalities are essential strategies to meet mental health needs, including during the COVID-19 pandemic. However, knowledge gaps remain regarding feasibility and effectiveness. Methods: This study assesses feasibility, acceptability and preliminary effectiveness of a CB-PSS intervention for conflict-affected adults in Colombia through parallel randomized controlled trials, one delivered in-person ( Findings: Attendance was moderate and fidelity was high in both modalities. Participants in both modalities reported high levels of satisfaction, with in-person participants reporting increased comfort expressing emotions and more positive experiences with research protocols. Symptoms of depression, anxiety and posttraumatic stress disorder improved among in-person participants, but there were no significant changes for remote participants in comparison to waitlist controls. Implications: This CB-PSS intervention appears feasible and acceptable in both in-person and remote modalities and associated with reduction in some forms of distress when conducted in-person but not when conducted remotely. Methodological limitations and potential explanations and areas for future research are discussed, drawing from related studies.
