This volume, edited by two psychiatrists and an internist for use by the outpatient-based primary care physician, was developed by using a unique collaborative approach, teaming psychiatrists with primary care physicians for each chapter. The type size is somewhat small, but generous use of white space results in a very readable format, which complements the direct, jargon-free, clinically relevant writing style. A brief introduction is understated yet effectively motivational. One chapter introduces the process of psychiatric assessment (emphasizing biopsychosocial understanding and interview technique), another discusses psychiatric diagnosis according to DSM-IV, 11 chapters present psychiatric disorders by diagnostic category, one deals with violence and aggression, followed by chapters labeled "Difficult Patient Situations," "Particular Mental Health Concerns of the Elderly, Gay Patients, and Women," "Somatic Treatments," and "Psychotherapeutic and Behavioral Treatments." This structure is logical and avoids excessive repetition but separates details of treatment from discussion of the disorders.
