This paper explores the application and justification of psychodynamic theory in a case study involving a young man with behavioral issues and substance abuse. It discusses the key concepts of psychodynamic theory, such as unconscious motivation and early childhood experiences, and how they can be used to understand and address the root causes of the individual's behavior. The paper also highlights the relationship-centered nature of psychodynamic theory and its relevance in counseling and substance abuse treatment. Overall, psychodynamic theory offers valuable insights and strategies for addressing the complex psychological factors contributing to the individual's difficulties.
