This book highlights the ongoing trend of brief treatments in psychotherapy for child and adolescent populations. Whereas their therapeutic predecessors may have taken 15 to 20 one-hour sessions or more, these newer therapies may begin to alleviate symptoms in only weeks, days, or even hours on the same day. Interest in child and adolescent brief and intensive therapies is currently at an all-time high on the heels of research showing impressive results for these interventions. Treatments such as One-Session Treatment for specific phobias which occurs in only one, three-hour session or Intensive Cognitive-Behavioral Therapy with Exposure and Response Prevention for obsessive-compulsive disorder which occurs 3-5 times weekly in 1-3-hour sessions over several weeks, are prominent examples. This volume builds on this growing interest and the emerging child and adolescent research, summarizing the efficacy of these interventions. Further, this volume will include key introductory chapters on the emergence of brief and intensive therapies, the ethics of their use, their cost-effectiveness, and the current state of the science. Brief therapies for specific disorders and via specific methodologies comprise separate chapters. Each chapter incorporates an exemplar case study (including a case overview, formulation/conceptualization, treatment description, follow-up, and recommendations for refractory cases). Also included are multicultural insights and ethical considerations. Furthermore guidance is provided on how to use the current and ongoing evidence base to inform formulation and treatment. This volume is timely and thorough in its presentation of the relevant literature and provides a much-needed resource for students, practitioners, and researchers alike.
