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 on their title How I Ran OCD Off My Land, the authors provide a 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 contains sample dialogues drawn from the authors' own experience, and appendices featuring reproducible rating scales, patient handouts, and tips and resources for parents.
