Validating a measurement of psychological, physical and sexual abuse against women in gynecological care within the Chilean health system.

Our objective was to create and validate a scale that would allow us to investigate women's experiences of violent practices in healthcare System. The scale was applied to large sample of women ( = 4563) from Chile. We analyzed data and conclude that the final instrument shows good reliability (α = .876 y ω = .921) and a factorial structure of three correlated factors referring to psychological, physical and sexual violence. Similarly, our analysis of the data -using a confirmatory factor analysis and multi-group factor analysis- reveals good fit indexes (CFI = .94 y RSMEA = .06) and supports the scale's metric invariance between groups in age (18 - 31 and 32 - 82) and healthcare centers (public and private). The prevalence rates of the different forms of violence predicted by the scale are reported.
