Field Guide to Psychiatric Assessment and Treatment is an invaluable diagnostic guide for the non-specialist practitioner. Covering the fundamentals of psychiatric assessment and treatment, the guide is structured to allow practitioners to quickly and accurately diagnose adult psychiatric illnesses. In the first section, decision trees help practitioners work from a typical presenting complaint through a differential diagnosis. Cross-references conveniently link diagnostic criteria to more detailed information on the individual disorders found in the second section. The guide provides treatment options commonly used in a primary care setting, while clearly highlighting when a practitioner should make a referral to a specialist.
