Acta de investigación psicol [online]. 2020, vol.10, n.1, pp.91-100.  Epub 11-Jan-2021. ISSN 2007-4719.  https://doi.org/10.22201/fpsi.20074719e.2020.1.336.

The present study aims to develop the short version of one of the four subscales of the Multidimensional Inventory of Infidelity. The original Inventory includes a total of 155 items distributed in four subscales: infidelity behavior subscale; infidelity motivation subscale; associated conceptualization of infidelity subscale; and consequences of infidelity subscale. This study developed the short version of the conceptualization of infidelity subscale using a confirmatory factor analysis. The subscale has six dimensions, and for each dimension three items with the highest factor loadings were chosen. The 18 items were answered by 940 heterosexual adults with an exclusive partner, 458 men and 482 women. The results show a model that uses all the original six dimensions and has a good fit for GFI, AGFI, CFI, and RMSEA. Cronbach’s alpha coefficient total was .90. It can be concluded that the obtained version is short, practical, valid, reliable and culturally relevant for Mexican adults. It can be concluded that the research successfully developed a short, practical, reliable, valid, and culturally relevant scale for Mexican adults.
