Abstract

Very few scales exist that measure violence against women and allow for comparative studies between Mexico and the United States. In this article, we present the results of a validation exercise for just such a scale. The scale was designed using, as a basis, some of the items in the Conflict Tactics Scale (CTS) and the Index of Spouse Abuse (ISA), in an attempt to differentiate among three types of violence: physical, psychological, and sexual. One hundred and twenty women from diverse social groups in each country responded to a questionnaire in which they were asked to consider the severity of each item on a scale from 1 to 100. Factorial analysis confirms that women assign a different average weight to each type of violence. An analysis of variance test confirms that the different groups of women interviewed evaluated each type of violence in a consistent manner. Very reasonable alpha coefficients were obtained. The paper concludes by demonstrating with an example the use of the scale in prediction modeling.
