This practical manual presents a cognitive-behavioral treatment program that has been proven effective in eliminating or alleviating OCD symptoms in children across a broad range of ages and aptitudes. Building upon and expanding their internationally acclaimed How I ran OCD Off My Land, the authors provide an empirically grounded guide to assessment, treatment planning, and skills-based intervention. Clinicians are taken through the four stages of treatment--psychoeducation, cognitive training, mapping OCD, and graded exposure and response prevention--in 13 to 20 clearly structured treatment sessions. The book is enriched by sample dialogues, "clinical pearls" drawn from the authors' own experience, and appendices featuring reproducible rating scales, patient handouts, and tips and resources for parents.
