Correspondence analysis: a method for classifying similar patterns of violence against women

Abstract

Violence against woman has received relatively little debate in society. It includes physical, psychological, and sexual abuse that jeopardizes the victim's health. Multivariate correspondence analysis and cluster analysis were applied to crimes reported to the Integrated Women's Aid Center in Rio de Janeiro, Brazil, to investigate associations between injury and define criteria for classifying the aggressions. Three groups of abuse were identified, differing according to the nature (physical, psychological, or sexual) and severity of the crimes. Less serious crimes consisted of threats and moderate physical injuries. The intermediate severity group included serious physical assault and threats. More serious crimes included death threats, rape, and sexual assault. The method thus allowed classification of the crimes in three groups according to severity.

“…Only recently, this type of analysis has been used in health care studies and has proven to be a very useful tool for the analysis of categorical data and to identify groups that share the same risk factors 18,19,[22][23][24][25] . In the present study, the formation of three clusters with distinct victimization profiles was observed.…”

“…Correspondence analysis, 8 which enables better graphic visualization of the relationships between these variables, was used to study the categorical nominal variables of the initial survey of the published articles. The general purpose of using correspondence analysis is to graphically represent the data frequencies in the form of a contingency table.…”

“…Além disso, a ACM permite que se estabeleçam perfis de cada caso observado, possibilitando avaliar a relação entre os casos e as variáveis analisadas, permitindo identificar grupos que possuam os mesmos fatores de risco. Para verificar a confiabilidade interna das dimensões formadas e obter uma estimativa apropriada da magnitude da variância, a ACM calcula o coeficiente de alfa de Cronbach 3,17 .…”
