About this trial

The goal of this clinical trial is to evaluate the effectiveness of a digital psychoeducational intervention, "What Were We Thinking" (WWWT), to prevent the development of postpartum depression and anxiety symptoms in first-time mothers in Chile. The study includes adult women with a healthy, full-term infant younger than two months who are receiving care in primary health centers.

The main questions it aims to answer are:

* Does participation in the WWWT intervention reduce depressive and anxiety symptoms at 3 months after the end of the intervention compared to usual care? * Does participation in the intervention improve maternal self-efficacy, perceived social support, and coparenting relationship quality compared to usual care? Researchers will compare an experimental group receiving the full WWWT intervention with a control group receiving usual care to determine the effectiveness of the intervention.

Participants will:

* Complete self-report questionnaires assessing depressive symptoms, anxiety symptoms, maternal self-efficacy, perceived social support, and coparenting at baseline and at 3-month follow-up * Be randomly assigned to either the intervention group or the control group * Receive the WWWT intervention between 4 and 10 weeks postpartum (intervention group), including:

* Fourteen psychoeducational video modules (3-5 minutes each) delivered via text messaging over 4-5 weeks * Individual contact with a trained facilitator through text messaging * One virtual group session with other mothers and a facilitator * Continue receiving usual care in primary health services (control group) and receive a shortened version of the intervention after the follow-up assessment

What Were We Thinking (WWWT) mHealth Intervention
Behavioral
The "What Were We Thinking" (WWWT) is a psychoeducational, preventive mHealth intervention designed for first-time mothers to reduce the risk of postpartum depression and anxiety. The intervention targets modifiable risk factors, including maternal self-efficacy in infant care and perceived social support. It is delivered between 4 and 10 weeks postpartum and includes three components: (1) fourteen psychoeducational video modules (3-5 minutes each) delivered via text messaging over 4-5 weeks, accompanied by reflective prompts; (2) asynchronous support from a trained facilitator via text messaging; and (3) one virtual group session led by the facilitator. Facilitators are trained health professionals and can refer participants to primary care services when needed.
