La infidelidad es un importante constructo a medir, al ser una problemática que conlleva consecuencias psicológicas y físicas (Buss, 2016; González et al., 2009; Shackelford et al., 2003). Se buscó determinar la validez y la confiabilidad del Inventario Multidimensional de Infidelidad (IMIN) para muestras colombianas. Se aplicó el instrumento a 674 participantes colombianos, 224 hombres (33.28%) y 449 mujeres (66.71%), con edades comprendidas entre los 18 y 81 años (M = 25.11;DE = 10.56), llevando a cabo análisis factoriales exploratorios, confirmatorios y de consistencia interna para cada subescala. En la escala de Tendencia a la infidelidad, se identificaron 3 factores que explicaron el 66.74% de la varianza total acumulada; en la escala de Motivos a la infidelidad, se hallaron siete factores, explicando el 65.02% de la varianza total; en la subescala de Creencias a la infidelidad, se obtuvieron cinco factores, explicando el 58.33% de la varianza acumulada; y en la subescala de Consecuencias de la infidelidad se hallaron dos factores claramente constituidos, que explican el 57.58% de la varianza acumulada. Todos los anteriores tenían modelos confirmatorios con adecuados niveles de bondad de ajuste y adecuados indicadores alfas de Cronbach, correlaciones ítem-ítem e ítem-prueba, además de concordancia con la propuesta original del instrumento.
Infidelity is a problem that entails psychological and physical consequences in humankind (Buss, 2016; González et al., 2009; Shackelford et al., 2003); thus, indicating the importance of measuring infidelity construct. The objective of the study was to determine the validity and reliability of the Multidimensional Infidelity Inventory (IMIN) for Colombian samples. For this, the instrument was applied to 674 Colombian participants, 224 men (33.28%) and 449 women (66.71%), with ages between 18 and 81 years (M = 25.11;SD = 10.56), carrying out exploratory factor analysis, confirmatory, and internal consistency for each subscale. In general, in the Motives to infidelity scale, three factors were found that explained 66.74% of the total accumulated variance; three factors were found in the Trend to Infidelity scale, explaining 65.02% of the total variance; in the sub-scale of Beliefs to infidelity, five factors were obtained, explaining 58.33% of the accumulated variance; and in the sub-scale of Consequences of infidelity, two clearly constituted factors were found, which explain 57.58% of the accumulated variance. All of them had confirmatory models with adequate levels of goodness of fit, adequate Cronbach alpha indicators, item-item, and item-test correlations, in addition to concordance with the original proposal of the instrument.
