The third edition of this handbook addresses not only the concept of resilience in children who overcome adversity, but it also explores the development of children not considered at risk addressing recent challenges as a consequence of the COVID-19 pandemic. The new edition reviews the scientific literature that supports findings that stress-hardiness and resilience in all children leads to happier and healthier lives as well as improved functionality across the lifespan. In this edition, expert contributors examine resilience in relation to environmental stressors as phenomena in child and adolescent disorders and as a means toward positive adaptation into adulthood. The significantly expanded third edition includes new and significantly revised chapters that explore strategies for developing resilience in families, clinical practice, and educational settings as well as its nurturance in caregivers and teachers. Key areas of coverage include: Exploration of the four waves of resilience research. Resilience in gene-environment transactions. Resilience in boys and girls. Resilience in family processes. Asset building as an essential component of intervention. Assessment of social and emotional competencies related to resilience. Building resilience through school bullying prevention. Resilience in positive youth development. Enhancing resilience through effective thinking. The Handbook of Resilience in Children, Third Edition, is an essential reference for researchers, clinicians and allied practitioners, and graduate students across such interrelated disciplines as child and school psychology, social work, public health as well as developmental psychology, special and general education, child and adolescent psychiatry, family studies, and pediatrics.
