AbstractAdverse mental health has been a major consequence of the COVID-19 pandemic. This review examines interventions to enhance mental health outcomes and well-being of populations during COVID-19. Four electronic databases (MEDLINE, PsycINFO, Embase, and CINAHL) were searched following Arskey and O’Malley’s six-staged scoping review process. Twenty studies were included in the review. Various study populations were included to ensure greater generalisability of results. Interventions informing treatment of mental health concerns during COVID-19 were included and classified into (a) prevention of poor mental health, (b) therapeutic interventions, and (c) other interventions. Preventative strategies (n = 16) included public health education, modified social media use, technology-based interventions, physical activity, policy adaptations, and therapeutic interventions. Treatment strategies (n = 7) included adapting existing treatment and the creation new treatment programmes and platforms. While current evidence is promising, future research should focus on novel effective interventions to address mental health issues during the pandemic.
