Case Conceptualization and Treatment Planning, Second Edition is a core textbook that teaches students in counseling, psychotherapy, and clinical psychology how to formulate a treatment plan that is integrated with theory and personalized to each client. Case conceptualization is the process of providing a theoretical explanation for what the client is like/experiencing and why they are like this. In order to do this, a student must draw from a variety of theoretical approaches. The treatment plan is the method/plan a therapist formulates in order to help the client achieve change. This book provides a detailed step-by-step guide for students to practice formulating case conceptualizations and treatment plans using a variety of popular theoretical models. Each chapter focuses on a specific theoretical approach. Within each chapter, the author provides client interviews and a sample case conceptualization followed by a treatment plan. Then the book presents another client interview and guides the student through the process of constructing a case formulation and treatment plan. This helps the student develop their plan in a guided, step-by-step process. Upon completion, the chapter contains questions to stimulate further critical thinking.
