Non-pharmacological interventions aimed at promoting the mental health of children and adolescents during the COVID-19 pandemic

ABSTRACT Background Interventions to promote mental health in pediatrics need to be effective, especially in crisis contexts. This systematic review proposes compile and analyze the findings of non-pharmacological interventions conducted in samples of children and adolescents during the COVID-19 pandemic, focusing on mental health. Method The research was carried out in PsycINFO, PubMed and Web of Science databases for empirical studies, including interventions in which measures of outcome variables were collected at least twice (pre and post). The studies’ samples were children and adolescents up to 19 years old, and interventions were developed throughout the COVID-19 pandemic. After eligibility analyses, 16 studies were included in this review. Results Studies used different theoretical approaches, focusing on promotion, prevention and treatment in mental health in specifics contexts. Some were delivered online, in-person, or in hybrid formats. Particularly, depression, the most frequently assessed outcome, demonstrated more favorable results within the interventions. However, due to considerable risk of bias, the analysis of results of many included studies should be performed with caution. Conclusions Most of the interventions necessitate further validation. However, the emergence of interventions during crises, such as the COVID-19 pandemic, provides an opportunity to expand evidence-based mental health practices, paving the way for their application in other crisis situations. Given that mental health prevention and promotion practices can be integrated into the roles of all healthcare providers, possessing insight into the most suitable evidence-based interventions can elevate the quality of care delivered.
