The research demonstrates the role of dialectical behavioral therapy in controlling and regulating emotions and feelings and reducing self-harm among adolescents with high functioning autism spectrum disorder. Adolescents with autism disorder are characterized by poor regulation of emotions and feelings, which affects their abilities to modify their emotional responses. These different behavioral patterns of individuals with autism spectrum disorder may have specific functions. For example, an activity may be enjoyable in itself for them, or may be the result of intense pressure and anxiety. The research used the descriptive approach, which is one of the most appropriate approaches to the nature of this research. The results of the research concluded that dialectical behavioral therapy (DBT) can be considered an informed treatment approach using adaptation and reconceptualization processes, that is, the wise, risky mind, and it is a promising treatment in addressing issues for adolescents with high-functioning autism spectrum disorder (ASD), especially those who have difficult or Offensive. DBT incorporates various elements of ABA, CBT, mindfulness skills, sensory-based therapies, psychosocial interventions, and emotion regulation skills, making it a more coherent and integrated approach to treatment.
