Accordingly, our goal in this section is to lay out the structure of cognitive-behavioral therapy (CBT) for trichotillomania (TTM) and other body-focused impulse control disorders, clearly explaining critical decisions such as the chosen sequence of techniques or whether a given technique is considered a core component or a module to be used in some but not all cases. The structure of this particular book is influenced by the work of experts who have gone before us in pioneering CBT for TTM, and is also informed by over a decade of our own clinical work and research on TTM across the developmental spectrum. We are indebted to those who developed this approach to treatment and also to those who built the extant literature on the psychopathology of TTM and related disorders. These clinicians and researchers did so in order to help alleviate the suffering of those afflicted with these conditions, and we endeavor to follow in their footsteps in continuing this important work.One of the first decisions we needed to make about the book's emphasis was whether to create a treatment guide that focused primarily on the treatment of adult TTM with a separate chapter on developmental adjustments needed to conduct CBT with children and adolescents. We chose not to do this for several reasons: 1) much of our work with TTM in the last decade has been with youth, and we felt that our experiences with this population warranted more discussion than was feasible in a single chapter; 2) although there is a clear need to adapt treatment to the developmental level of the patient, the underlying core principles cut across the developmental spectrum and hence were more efficiently considered together; and 3) TTM is typically a pediatric onset disorder, and thus its treatment should be given equal weight compared to the treatment of adults. We encourage therapists with an interest in CBT for TTM but have worked primarily with adults to consider seeking additional training, supervision, and clinical experience in treating youth: there is a serious problem with treatment access for TTM in general, but this problem is particularly pronounced for families seeking help for their children.The book is organized into four subsections: 1) Overview and Assessment; 2) Treatment: Core...
