The introductory chapter of this book discusses definitions of domestic violence, issues of power and control, the prevalence of the problem, the effect of domestic violence on the medical system, and reasons why physicians fail to identify abuse. The profile of domestic violence victims is discussed in terms of gender, ethnic and socioeconomic status, age, marital status, personality traits, sexual orientation, pregnancy, disabilities, immigration status, use of alcohol and drugs, family history, relationship variables, and abuse of children. Issues pertaining to abusers discussed here include substance abuse, critical risk factors, dominance of men over women, and secrecy and denial. Recognition of domestic violence can be improved through patient history and demeanor, companion's behavior, direct questioning, routine screening, and physical examination. When abuse is detected, the physician has many avenues for action: referrals to services and shelters, documentation, treatment, counseling, legal services, and follow-up care. Specific legal issues may include mandatory reporting, duty to warn, liability for reporting, and legal options for the patient. The book discusses how the medical community can prepare itself for an optimal response to domestic violence. 3 appendixes
