Unhappy Hours: Alcohol and Partner Aggression in the Americas (edited by Kathryn Graham, Sharon Bernards, Myriam Munn?©, and Sharon Wilsnack) is the Organization s latest contribution in the effort to better understand partner violence and, in so doing, find more effective interventions to right this wrong. The book explores the relationship between alcohol consumption and partner violence gathering information from both the aggressor's and the victim s perspective. It brings to light evidence of alcohol's impact on partner aggression from 10 countries in the Americas (Argentina, Belize, Brazil, Canada, Costa Rica, Mexico, Nicaragua, Peru, Uruguay, and the United States), and represents an unprecedented effort to collect and analyze information from the general population that can be compared across countries. Despite wide differences between countries and cultures, there are common characteristics and trends across countries regarding the relationship between alcohol and partner violence. This publication will be of interest to a variety of audiences, including the academic and research communities, students, health promoters, health professionals, communicators, ministries of public health, and the victims of partner aggression.
