Children with disruptive disorders have the greatest difficulty controlling their aggressive impulses. In a chart review of the psychoanalyses of 135 children with disruptive disorders matched on demographic, clinical, and treatment variables with children who had other emotional disorders, Fonagy and Target (9), like the authors of the studies in the volume under review, found that, overall, improvement rates were lower for disruptive disorders than for emotional disorders. Furthermore, again like the finding of studies described in this volume, the treatment of nearly one-third of the children terminated within 1 year. However, and most important, of the disruptive children who remained in treatment, 69% were no longer diagnosable at the end of treatment. In other words, Fonagy and Target’s studies, like those in the present volume, indicate that we need to understand what techniques are most effective in engaging and maintaining an ongoing psychotherapeutic relationship. The evidence is clear—if patients with severe problems can stay in treatment, they get better.
