This volume examines the undesirable or harmful cognitive, emotional and behavioural side-effects of COVID-19, and of the behavioural restrictions imposed by governments on their populations during the pandemic. Societal lockdowns and other intervening behavioural restrictions, built significantly around social isolation, used by governments to control the spread of COVID-19 disrupted the lives of most people. There were economic costs for many as workplaces closed down, as well as severe stresses on friendships and romantic relationships, an increase in instances of abuse and domestic violence, and concerns about people drinking too much alcohol or gambling too much as compensatory behaviours. Understanding which people were at risk, and in what ways, could teach important lessons for the future. Presenting a timely review of the most recent international research and evidence, author Barrie Gunter assesses the major collateral, psychological side-effects of the pandemic. Looking forward, Gunter also considers how new models might be developed that take into account not just the need to halt the spread of a new virus, but also minimise collateral damage which could be every bit as severe in both the short term and longer term. Identifying and analysing the nature and severity of collateral side-effects of pandemic-related behaviour restrictions, this is essential reading for students and researchers in psychology, public health and medical sciences, and policy makers assessing government strategies, responses, and performance.
