“An invaluable resource for any therapist seeking to advance their clinical skills beyond the limitations of manualized OCD treatments. Whittal and colleagues present a well-articulated case formulation framework that enables therapists to tailor CBT to the specific needs of each individual. Case presentations elegantly demonstrate how the authors' model can be applied to contamination fears, harm obsessions, scrupulosity, and a range of other OCD presentations. This book embodies solid research masterfully tempered by clinical wisdom, and represents a fitting tribute to the authors’ mentor, Jack Rachman.”
