Spanish Adaptation of the Illinois Sexual Harassment Myth Acceptance

Abstract

Sexual harassment is among the most serious forms of gender violence, and what all violent acts have in common are the many myths associated with them. Three studies were conducted to adapt a Spanish version of the Illinois Sexual Harassment Myth Acceptance (ISHMA) scale, which assesses myths about sexual harassment. The first study aimed to, for the first time, present psychometric data on the Spanish version of the ISHMA. The participants were 339 college students. After adapting the items and measuring their content validity, we examined the test’s dimensional structure, statistically analyzed the items, and determined the instrument’s reliability (α = .91 for the total scale and between .77 and .84 for the different dimensions). Study 2 involved 326 adult participants from the general population and its objective was to evaluate the scale’s dimensional structure through confirmatory factor analysis (χ2 143 = 244.860, p < .001; GFI = .952; CFI = .958; RMSEA = .034 [.026 – .041]). The third study was conducted in order to measure convergent validity in both students and adults from the general population. Differences by gender were found in all dimensions being the females’ means higher than males (Cohen´s d between .38 and .62). Our findings suggest the Spanish version of the ISHMA is a useful instrument to study myths about sexual harassment.
