Psychometric properties of the multidimensional inventory of infidelity in Jordanian society

Abstract

The concept of infidelity is one of the basics of marital life, and on it depends the satisfaction, compatibility and happiness of the spouses. Therefore, there is an urgent need in Arab countries to develop tools that contribute to dealing with this problem and its painful consequences. Infidelity is a problem that affects a person psychologically and physically, and it is important to develop a measure to identify this problem. This study aimed to verify the validity and reliability of the Multidimensional Infidelity Inventory (IMIN) on a Jordanian sample. For this purpose, the Spanish version of the questionnaire was translated and applied to a Jordanian sample of 732 persons (291 men, 441 women). The results showed that three factors explained 70.28% of the total variance of the infidelity trend subscale, and seven factors explained 68.43% of the total variance of the reasons for infidelity subscale. Five factors explained 61.21% of the total variance of the infidelity beliefs subscale, and two factors explained 57.45% of the total variance for the infidelity consequences subscale. 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. This instrument can assess, diagnose, and overcome infidelity.
