Mental health consequences of COVID-19 pandemic on adult population: a systematic review

Abstract

Purpose The spread of novel coronavirus 2019 (COVID-19) has infected millions of people worldwide. Public health emergencies caused by COVID-19 affect not only people’s physical health but also mental health. This paper aims to summarize recent research findings on the mental health impact of COVID-19 experienced by the general adult population. Design/methodology/approach This paper used a systematic approach and aimed to review the literature on mental health problems faced by general adults during the COVID-19 pandemic. The PubMed database has been selected randomly from the Google Scholar, Cochrane Library, Embase and PubMed databases. Ten journal articles published between January and July 2020 were selected from the PubMed database for the final review. Findings There is growing evidence that COVID-19 may be an objective risk factor for mental distress among the general adult population. More psychological and social support should be provided to protect adult people’s mental health. Practical implications This review will help policymakers develop mental health interventions for the general adult population vulnerable to psychological distress because of COVID-19 pandemic. Originality/value This paper is original and contributes to the existing knowledge that the mental health challenges of COVID-19 are widespread. There is, therefore, a need for more psychological interventions for adults, older adults, in particular, to promote mental health and reduce the distress associated with public health emergencies caused by COVID-19.
