But I digress. The book is laid out nicely. Several introductory chapters set the scene by providing an overview of assessment approaches and admonitions not to trivialize these disorders—they are physically and socially quite disruptive. The midsection of the book is its strength—nine chapters, three each devoted to tic disorders, trichotillomania, and oral-digital habits (these include finger sucking and nail biting). (Unfortunately, the book does not deal with naso-digital habits.) For each condition, there is a chapter on characteristics that includes diagnosis, demographics, comorbidities, and etiologies. Next comes a chapter overviewing behavioral interventions for the condition (and as an added bonus, the tic and trichotillomania chapters also include brief, up-to-date, and fairly balanced sections on pharmacological interventions). The final chapter of each of these sections gets down to the nitty-gritty—the habit reversal treatment manual for dealing with the disorder. Herein lies a step-by-step protocol for applying habit reversal to the treatment of repetitive behavior disorders. Reading these chapters gives one a firm grasp of the procedure, an understanding of its applicability, and an appreciation of its complex simplicity (it seems overwhelming until broken down into its component parts). One will also recognize that time and tedium are involved in the implementation of habit reversal and surmise that its success requires a unique matchup of patient and therapist.
