Within each section, essays by contributors discuss the most important issues and developments in the diagnosis and treatment of addiction. The opening essays establish a solid theoretical foundation by outlining behavioral, familial, and psychoanalytical explanations for the origins of addictive behavior. The later essays build on that base by overviewing diagnostic and treatment issues concerning addiction among Native Americans, the elderly, victims of traumatic brain injury, adult children of alcoholics, and teenagers. Useful appendixes list additional sources of information and describe certification for substance abuse professionals in each state. Psychologists, psychiatrists, and substance abuse counselors will find this handbook a necessary addition to their professional libraries.
