Equivalencia y baremos del Hurlbert index of sexual assertiveness entre hombres y mujeres Españoles

Abstract

The purpose of the present study was to analyze the measure-ment invariance and differential item functioning of the Spanish version of the Hurlbert Index of Sexual Assertiveness across gender. The sample was composed of 1,600 women and 1,598 men from Spain, with ages ranging from 18 to 84 years old. The Hurlbert Index of Sexual Assertiveness only showed weak invariance for men and women. The differential item func-tioning analysis showed that only item 2 ("I feel that I am shy when it comes to sex") flagged moderate uniform differential item functioning. More specifically, women tended to respond "Always" to this item more frequently than did men. Results strongly suggested eliminating item 2, re-sulting in a final version with 18 items clustered into two dimensions with good reliability values for men and women. Standard scores for both Initia-tion and No Shyness/Refusal reflected traditional sexual scripts for men and women. © 2014: Servicio de Publicaciones de la Universidad de Murcia.
