Emotional dependency is defined as the extreme need of affection that someone feels towards his/her partner. In childhood and adolescence early maladaptive schemas that could affect dating relationships are formed. Therefore, the aim of this study was to analyze emotional dependency by sex and age and its association with early maladaptive cognitive schemas in youth and adolescents who have maintained at least one dating relationship. Emotional dependency, early maladaptive schemas and variables associated with dating relationships in young adolescents were examined in 1092 participants from different school and colleges. Emotional dependency was found to be significantly higher in boys depending on age. Early maladaptive schemas also showed a significant correlation with Emotional Dependency. These results provide insights into adolescents’ dating relationships and how emotional dependency affects them.
