CAMPO-ARIAS, Adalberto et al. Validating the Edinburgh Postnatal Depression Scale's internal consistency and factor structure amongst pregnant women in Cartagena, Colombia. Rev Colomb Obstet Ginecol [online]. 2007, vol.58, n.4, pp.277-283. ISSN 0034-7434.

Objectives: determining the Edinburgh Postnatal Depression Scale's internal consistency and factor structure amongst pregnant women in Cartagena, Colombia. Materials and method: this was a validation study (lacking a gold-standard) designed for use with 200 literate, pregnant women aged 18 to 42 (24.3 average age, 5.2 SD) living in low-income neighborhoods and attending a public obstetric clinic in Cartagena, Colombia. Internal consistency (Cronbach's alpha) and factor structure (exploratory factor analysis) of the Edinburgh Postnatal Depression Scale were computed. Results: the Edinburgh Postnatal Depression Scale presented 0.78 internal consistency and a three-dimensional structure (depression, anhedonia and a hopeless-guilty mood) explaining 59.9% of variance. Conclusions: the study showed that the Edinburgh Postnatal Depression Scale had high internal consistency and was composed of a three-dimensional structure exploring the concept of depression in low-income pregnant women in Cartagena, Colombia.
