Feasibility Study and Pilot Hybrid Effectiveness-Implementation Trial for the Universal Prevention of Maternal Perinatal Mental Disorders as Normalized Routine Practice (e-Perinatal Pilot)

This pilot clinical study investigates the feasibility, acceptability, and preliminary implementation and effectiveness of the e-Perinatal app, an innovative, personalized mobile health (mHealth) intervention designed for the universal prevention of perinatal mental disorders. The study will be conducted as a two-arm, cluster-randomized, hybrid type 1 trial within routine maternal care settings in primary healthcare centers in Andalusia, Spain. Participants will include pregnant and postpartum women (up to five months postpartum) and their partners. Primary healthcare centers will be randomized to either the intervention or control arm. The primary objective is to evaluate the feasibility of integrating the e-Perinatal app into routine maternal care. Secondary objectives include assessing the acceptability of the intervention among women, partners, and healthcare professionals and exploring preliminary effectiveness outcomes, such as the incidence of perinatal depression and anxiety in women, changes in depressive and anxiety symptoms in both women and their partners, and potential impacts on infant health and development. The study hypothesizes that the e-Perinatal intervention will be feasible and acceptable for pregnant and postpartum women, their partners, and healthcare professionals involved in routine maternal care. Participants will be recruited from primary healthcare centres and allocated by cluster randomization to either the intervention group, which will receive the e-Perinatal app along with standard maternal care, or the control group, which will receive standard maternal care and monthly psychoeducational emails.
