Time and again, children, adolescents, and adults exhibit behaviors that do not meet the expectations of others. Behind this lie social evaluation processes, which often label such deviations as personal problems or disorders, specifically as behavioral disorders. However, the concept of behavioral disorder is characterized by a limited perspective. This book aims to present a more nuanced viewpoint in contrast to the reductionist ideas associated with it. It is linked to the notion of being able to change the perspective on these behaviors, thereby leading to a transformed approach towards those children, adolescents, and adults for whom challenging behaviors are of particular significance in their life management.
