The purpose of this study was to design and validate a psychometric scale to measure attitudes towards intimate partner violence. To do so, a theoretical review was started, and then a specification table was designed, which guided the construction of the reagents. Then, the process of evaluation by judges, the purification of the reagents and the adjustment of the scale for its subsequent application to 357 people were carried out. Finally, the factor analysis of the data obtained was made, as well as an analysis of reliability and internal consistency. As a result, an instrument consisting of 30 reagents was built, with high rates of validity (> .6) and reliability (.859) to measure attitudes towards intimate partner violence.
