“…The Portuguese version of the Edinburgh Postnatal Depression Scale, a self-report questionnaire composed of 10 items in a Likert scale of 4 points (0 -3), was used to assess depressive symptomatology. This questionnaire has been used in several studies with pregnant and postpartum women (e.g., Da Costa, Larouche, Dritsa, & Brender, 2000;Eberhard-Gran, Tambs, Opjordsmoen, Skrondal, & Eskild, 2004), including use in Portugal (Areias, Kumar, Barros, & Figueiredo, Teenage pregnancy1996a, 1996bAugusto et al, 1996;Figueiredo, 1997). Although this instrument does not assure a clinical diagnosis of depression, a score higher than 13 indicates the probable presence of a major depressive episode (Augusto et al, 1996).…”
