Measuring domestic violence against Egyptian women and its consequent cost using a latent variable model.

Abstract

Background: Domestic Violence is a threatening worldwide problem. Its consequences against women can be dramatic, as it negatively affects women's quality of life reflected in their general wellbeing including physical, mental, emotional and sexual health, in addition to the economic cost. Both domestic violence and its cost are multidimensional constructs that cannot be directly measured.

Methodology: In this study, a latent trait model is used by applying item response theory to measure both domestic violence and its consequent cost via thirty-five observed variables. Accordingly, the study fills a gap in the literature since it is the first attempt to examine the relationship between domestic violence and its consequent cost in Egypt using latent variable modelling rather than simple descriptive statistics. Each construct is considered as a multidimensional latent variable. The overall latent trait model also estimates the relationship between domestic violence and its consequent cost. The effect of a number of socioeconomic covariates on domestic violence is examined within the model. The proposed model is fitted to data from the 2015 Egypt Economic Cost of Gender-Based Violence Survey (ECGBVS) using Mplus software.

Results: The study shows that psychological violence is equally important in measuring domestic violence, as physical violence. The cost resulting from domestic violence relies in its measurement both on the reduced quality of life and the monetary cost endured by the violated woman and children. For socioeconomic covariates, it is shown that domestic violence is affected by women's and husband's age, educational level, and husband's occupational status.

Conclusion: Domestic violence is measured by summarizing four forms of violence: physical, psychological, sexual and economic violence, in a single continuous latent variable measuring "Domestic Violence". Similarly, Cost is measured by summarizing three forms of consequent cost of violence: economic cost, cost on children and cost on women's quality of life, in another a single continuous latent variable "Cost". Each of these dimensions is measured by a number of aspects, reflecting the multidimensional nature of the variables. The fitted latent trait model ensured the positive relationship between Domestic Violence and its consequent multidimensional cost.
