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, χ2(365) = 750.14, p<.05; RMSEA= .07; CFI= .92; TLI= .92; and the presence of a partner, χ2(365) = 750.30, p<.05; RMSEA= .06; CFI= .92; TLI= .92.
