The book is divided into three sections: Introduction, Treatment Strategies, and Special Topics. The introduction covers the implications, prevalence, and assessment of psychiatric comorbidity. Treatment Strategies addresses the effects of comorbidity on the treatment of anxiety, mood disorders, schizophrenia, and substance abuse. For each class of comorbid disorders there is a chapter on psychological treatment or psychotherapy and a chapter on pharmacotherapy. The third section considers the impact of comorbidity on suicide, on assessment and treatment of children and adolescents, and on the elderly. Such a format lends itself to redundancy, and indeed there is a great deal of repetitiveness throughout.
