On behalf of the Research Society on Alcoholism, I am pleased to introduce this thirteenth volume of Recent Developments in Alcoholism about alcohol and violence. Current concepts are presented in well-organized sections that focus on epidemiology, neurobiology, psychology, and family issues. It is becoming increasingly clear that age, gender, socioeconomic circumstances, and genetics affect aggressive behavior and vulnerability to alcoholism. This volume contains up-to-date discussions of these issues. Indeed, the information presented here will help all alcohol researchers to identify biological and social factors that contribute to the comorbidity of alcoholism and aggression. The editors and associate editors should be congratulated for bringing together such important information. This volume will.
