Anxiety is one of the most common childhood disorders. Even when it is not easily recognizable, it exists and can create serious problems for the child (e.g., separation anxiety, school phobia, eating disorders, etc.) and affect their adolescence and adult life. The Anxiety Dinosaur is a versatile tool that contributes to the prevention of anxiety disorders in children aged 6-12 years. It is a comprehensive psychoeducational program for learning problem-solving skills and managing stressful situations with techniques based on the cognitive-behavioral approach. Through a series of enjoyable activities and exercises, the child is helped to develop the appropriate skills to identify and control their dysfunctional thoughts, negative emotions, and inappropriate behaviors. Thus, they are able to solve their problems on their own, practice self-control, and handle anxiety-inducing situations that concern them. The goal of the program is the smooth adaptation to school and social life, the development of relationships with peers, and the establishment of skills that allow the child to successfully cope with the challenges of everyday life.
