Which of these populations has the EPDS been validated for?

The Edinburgh Postnatal Depression Scale (EPDS) has been validated for both prenatal and postpartum women as well as teens, making this option the correct answer. The EPDS is a widely used tool designed specifically to identify the presence and severity of depressive symptoms during the perinatal period, which includes both pregnancy and the time after childbirth.

Research indicates that it effectively screens for perinatal depression across different populations, including a diverse range of genders and age groups, but it is especially designed for those directly affected by the perinatal experience. This validation not only enhances its reliability in detecting depression but also supports its use in various clinical settings, ensuring that appropriate interventions can be initiated based on the assessed needs of these populations.

In contrast, the other choices focus on specific demographics that do not encapsulate the broader validation of the EPDS. Therefore, recognizing the comprehensive applicability of the EPDS to both the prenatal and postpartum phases in various individuals, including teens, is critical for effective mental health screening and support during the perinatal period.
