Developmental trauma has become a controversial topic in the mental health profession, contributing to a growing rift between clinicians and academicians. The controversy centers on the impact of relational trauma during children’s first three years of life. Clinicians say that developmental trauma has deep and long-lasting effect on child development that contributes to illnesses and degenerative diseases in adulthood. Academicians say that the impact of this early relational trauma is negligible, and only a part of the diagnostic and treatment picture. This book examines the historical factors that have caused this professional controversy, and how it is provoking a game-change in the way that mental health professionals conduct their practices. This book also examines the personal impact of developmental trauma, and how it can become a different kind of life game-changer. Rather being a self-fulfilling prophesy for pain and suffering, it can also serve as a catalyst for personal transformation and meaning-making. Recent research indicates that one’s beliefs about stress, not stress itself, determines whether it is positive or negative. This book helps readers change their beliefs about stress, and reframe the concept of developmental trauma into developmental growth. This perspective empowers readers towards intrapsychic integration and personal transformation.
