Outcomes
The principal outcome was the prevalence of depression, measured by the
Edinburgh postnatal depression scale (EPDS), with a discrimination
threshold set at 11 and above.24
Our secondary outcomes were the mean EPDS score and the risk of
postpartum depression and, on the other hand, the prevalence, mean
scores, and risk of other psychological disorders: anxiety, measured by
Spielberger’s State-Trait Anxiety Inventory (STAI) form Y-A with a
discrimination threshold ≥46,25 generalised anxiety
disorders, measured by the Generalised Anxiety Disorder (GAD-7) with a
discrimination threshold >7,26 and
post-traumatic stress disorder (PTDS), by the Revised Impact of Event
Scale (IES-R) with a discrimination threshold ≥30.27
