The Handbook of Psychological Assessment, Case Conceptualization, and Treatment marks the first publication to systematically link these three fundamental elements of mental health practice across the age spectrum. Editor-in-chief Michel Hersen has gathered leading international scholars and practitioners in two volumes to present the latest evidence-based findings regarding best practices for a number of prevalent DSM disorders and other issues facing individuals of all ages, as well as special groups, such as married couples and older adults. Following an overview of assessment, case conceptualization, and treatment using a behavioral focus, along with relevant medical, pharmacological, and ethical issues, each volume's chapters on specific disorders and issues follows a structured format to ensure consistency of coverage across chapters and volumes. Following a description of the problem, relevant diagnostic considerations are addressed, as well as specific influences affecting the conceptualization of the case, behavioral and/or medical treatment options, and a comprehensive case study. All mental health professionals, students, and researchers will find these volumes to be an important resource for timely and proven information for effective practice
