Apego Adulto y Comportamiento Infiel en Estudiantes Universitarios de la Facultad de Medicina e Ingeniería de la Universidad de Cuenca, en el Año 2025-2026

Abstract

Introduction: Romantic relationships are influenced by psychological dimensions such as adult attachment and infidelity related behaviors, which affect relational dynamics. Objective: The present study aimed to analyze adult attachment style and the tendency toward infidelity among university students from the Faculties of Medicine and Engineering at the University of Cuenca, considering the sociodemographic variables of sex and age. Methodology: A quantitative study was conducted using a non-experimental design, a cross-sectional approach, and a descriptive scope. The sample was non-probabilistic by convenience and consisted of 100 university students. The Adult Attachment Questionnaire and the short version of the Multidimensional Inventory of Infidelity in Dating Relationships were applied. Data analysis included descriptive statistics and inferential tests such as chi-square, one-way ANOVA, and Spearman correlations. Results: Insecure attachment styles predominated, particularly dismissive avoidant attachment, with no cases of secure attachment identified. Mean scores for infidelity were low across all subscales. No statistically significant associations were found between attachment style and infidelity, nor between sex or age and attachment or infidelity related behaviors. At a descriptive level, men showed higher mean scores in sexual infidelity, whereas women showed higher mean scores in emotional infidelity. Conclusions: In the analyzed sample, no significant relationships were found between adult attachment and infidelity, highlighting the relevance of relational and sociocultural context in university students.
