Invariance of the Emotional Dependence Questionnaire between sexes and relationship status in university students

Abstract

This work aimed to explore the factorial structure and the measurement invariance between groups of the emotional dependence questionnaire (EDQ). Participants included a random sample of 569 university students, 67.8% women and 51.2% had a romantic partner. The multigroup confirmatory factor analysis (MG-CFA) showed metric invariance for the EDQ. Particularly, the findings indicate that five of six scales of the questionnaire have an average variance extracted higher than 53% and a composite reliability of more than 0.75; the borderline expression scale was excluded. It was found that the EDQ has a strong measurement invariance degree between genders, ?2(365) = 750.14, p<.05; RMSEA= .07; CFI= .92; TLI= .92; and the presence of a partner, ?2(365) = 750.30, p<.05; RMSEA= .06; CFI= .92; TLI= .92.
