Preliminary Evaluation of the Effectiveness of the Intervention And Now What? to Promote Maternal Mental Health in the Postpartum Period in the Primary Health System in Chile.

Mental health symptoms are common in new mothers. Despite the availability of effective screening and referral in the primary health system in Chile, very few women access treatment due to diverse barriers (i.e., long waiting lists and insufficient knowledge about postnatal depression and treatment). This highlights the importance of using a preventive approach. Currently in Chile there are no universal preventive interventions, although they are available internationally.

Thus, this study seeks to assess if it's feasible and acceptable to offer an alternative intervention that can be delivered remotely by mobile phones, to support women in the early postpartum period by promoting confidence and reducing distress in first time mothers. By doing so, it will increase the number of available interventions to promote and prevent children´s early adverse experiences related to maternal mental health problems.

This study accounts for the feasibility, acceptability and preliminary effectiveness of "What Were We Thinking" (WWWT) a psychoeducational intervention -delivered remotely via communication technologies- to prevent symptoms of postpartum depression and anxiety in new mothers. WWWT was developed in Australia and has been culturally adapted to be used in Chile. The m-health version of the Chilean adaptation of WWWT includes:

1. Psychoeducational information for understanding and managing infant behavior and about parenting. Modules on understanding and managing infant behavior include information on: infant temperament, including such as differences in the reactivity, responsivity and regulation of young infants; amount and known and unknown reasons for infant crying; stimulation, over-stimulation and soothing; infant sleep needs and optimal sleep habits; the use of settling strategies to achieve these while supporting breastfeeding; and establishing sustainable routines of daily care: the feed, play, sleep routine. Modules on matters relating to parents include: gendered differences in the losses and gains of parenthood; differences in emotional needs and the potential for adverse reproductive events to have lasting psychological effects on women after the birth of a baby; and developing strategies to assist couples to address these in a non-confrontational manner. This information will be delivered through instant messaging services for mobile phones (i.e., Whatsapp) 3 times a week for four-week period. Each module will include a very brief video offering information regarding a specific topic, a proposed personal exercise and the invitation to assess the perceived usefulness of the information received. Some modules include links to external, complementary information from the Chilean Infancy Policy.
2. Contact with the program trained facilitator. It will allow mothers to ask questions that arise from the topics addressed in the psychoeducational videos and share their personal experiences. The facilitator responses will focus on aiding the understanding and elaboration of the contents. This will be done through instant messaging service for mobile phones (i.e., Whatsapp). In the present study, the facilitator will be a mental health professional of the research team, that has been trained on the intervention model.
3. Group virtual meeting. A virtual group meeting will take place with mothers and their partners (or significant others) and the program facilitator. The group meeting seeks to offer an instance were new mothers and fathers can share their experiences regarding their parenthood and the changes it has involved in their daily lives, as well as providing the opportunity for developing support networks among them.

This pilot study will use a mixed design. The quantitative component will consist of a before-after design with control group including 90 adult mothers of child aged 6-8 weeks who receive health care in a primary health centers in Santiago. Mothers will be randomized into the experimental (EG) or control groups (CG) in a rate of 1:1. Mothers in the EG will receive the m-health version of WWWT intervention plus the usual treatment that primary health centers (TAU) provided to children. Participants in the CG will be subject to TAU. TAU for children under one year of age include routine health checks by health professionals (nurse or doctor), every month from 0 to 4 months of age, and at 6, 8 and 12 months of age. The objective of the routine health care check is to carry out a comprehensive evaluation of the child's development and growth, guide parents and caregivers regarding child development, health and upbringing of the child. Also, promoting exclusive breastfeeding, healthy mother/child bonding (by detecting relevant alterations in this area) and encouraging paternal participation in upbringing and care of the child. Finally, in the health check-ups at 2 and 6 months of age of the child, Edinburgh Postpartum Depression Scale is used for screening depressive symptoms in mothers. At risk cases are referred for mental health assessment and care. A waiting list procedure will allow the delivery of the intervention to control women once the data collection for the study has been completed.
