In addition, the book depicts the preventive strategies currently used in various social settings (school, family, sport club, health policies) aimed not only at reducing lifestyle risk behaviors, but also at improving resilience, happiness, social involvement, self-esteem, and sociability. This update is essential in the light of the fact that, to date, prevention has mainly been directed towards adolescents with physical or mental disorders rather than their healthy peers. As such, the book offers a valuable tool for pediatricians, child and adolescents psychiatrists, and for all professionals involved in Health Promotion and Disease Prevention.
