Partner’s Emotional Dependency Scale: Psychometrics

Emotional dependency in a partner implies an excessive permanent affectional bonding to the other individual that is dysfunctional, associated with low self-esteem and conceals a lack of affection. Emotional dependency generates a series of negative emotional consequences: symptoms of anxiety and depression, obsessive thoughts, sleep disorders and abandonment of social relations and leisure. In recent decades several tools have been developed to measure emotional dependency, but they are more focused on measuring dependent personality disorder, centered on an exclusively young population or are not validated in the Spanish population. The aim of this research is to design and validate a new scale to overcome these limitations.

The sample population included 166 adults (53 men and 113 women) from the general population, to whom a new scale was applied (partner’s emotional dependency scale, SED), as well as the CDE (Emotional Dependency Questionnaire).

The scale has a unidimensional structure, showing good internal consistency (Cronbach’s alpha = .90) and a high convergent validity with the CDE (r = .86). There is no difference between men and women with regarding emotional dependency. Some cut-off points have been established based on the degree of emotional dependency (low, moderate, high and extreme).

The SED is a brief assessment tool, simple to conduct and allows the degree of emotional dependency to be assessed unidimensionally with regard to a stable intimate relationship (current or past) in a normative population.
