Infidelity is the action or state of being unfaithful to a spouse or other sexual partner. Study shows that infidelity is not limited to any demographic or culture but across various societies, ages, and relationships. Reasons behind infidelity are diverse and can range from dissatisfaction in the current relationship, desire for novelty or excitement, emotional or sexual needs not being met, to personal insecurities or a lack of commitment. Currently, about 40 to 60% couples engages in infidelity due to financial reasons. However, a study carried out in Nigeria and Ghana finds that more women involve in infidelity than their men counterpart. Similarly, their Ghanian counterpart result was in the same direction. But many of the men and women who engages in infidelity were people without any religion affiliation. Furthermore, the study showed that many of the couples who were cheated upon has severe consequences, ranges from psychological damage, low/lack sexual confidence, personal confidence, and other post-traumatic stress disorder. Therefore, there is an eminent need to determine factors that could reduce or eliminate infidelity in the Nigerian society.en-USInfidelity; IBQ Questionnaire; Reliability; Validity.Article6164
