Book excerpt: Once understood as useful but optional, case conceptualization is now considered an essential clinical skill. Clinicians looking for resources to assist in learning and mastering this competency must consider approaches that are both effective and clinician-friendly. A truly clinical effective approach explains and guides treatment, and most importantly, predicts challenges and obstacles that are likely to arise over the course of treatment. Most approaches emphasize explanation and treatment guidance but seldom include the third function which helps anticipate like challenges. If not proactively addressed, these challenges are likely to result in therapy interference or premature termination. Research show that such case conceptualization is essential in determining the course and overall effectiveness of therapy, and it can be completed in as little as fifteen minutes. The 15 Minute Case Conceptualization guides clinicians step-by-step through the process of case conceptualization. Accessible and effective, this book is a must-have for clinicians who want to master this essential skill. Book jacket.
