Key Takeaway
Note that this is a study protocol; no clinical results or outcomes are currently available.

This publication is a study protocol for a randomized controlled trial. It outlines a plan to evaluate the PROMATER intervention, a 3-week online program consisting of 6 modules. The program addresses maternal expectations, self-criticism, perinatal mental health, social support, self-compassion, and mindfulness and mother-infant bonding. The study is designed to assess the intervention's impact on women between 28 and 34 weeks of gestation.

The primary outcomes are self-compassion (measured by the compassionate self-responding score) and self-criticism (measured by the uncompassionate self-responding score). Secondary outcomes include postpartum depression, anxiety, quality of life, social support, and mother-infant bonding. The study design includes a baseline, post-intervention, and 3-month postpartum follow-up.

Because this is a protocol, no results, effect sizes, or safety data are reported. The authors note the intervention is designed to maximize reach and minimize cost, with potential for scaling in routine perinatal care. Clinical application is currently limited to the planned design of the study.

A new study is planning to test an online program called PROMATER. This program is designed for pregnant women between 28 and 34 weeks. It focuses on helping mothers manage their expectations and reduce harsh self-criticism during the final stages of pregnancy.

The three-week program includes six different modules. These lessons cover topics like social support, mindfulness, and bonding with the baby. The goal is to give mothers practical tools to improve their mental health and feel more confident as they prepare for their new roles.

Researchers will compare this program against a similar version that does not include specific tools for self-compassion. They will check if the PROMATER group shows better results in areas like anxiety, depression, and overall quality of life. The study will also check these results three months after the baby is born.

This online approach is designed to be easy for many women to access. By moving the program online, it can reach more people and be more affordable. This could make it easier for doctors to offer mental health support to many mothers who need it during a very important time in their lives.

What this means for you:
This upcoming study tests an online program to help pregnant women feel more self-compassionate and less stressed.

Common questions

What is the PROMATER program?

PROMATER is a 3-week online program with 6 modules. It covers maternal expectations, self-criticism, perinatal mental health, social support, self-compassion, and mindfulness and mother-infant bonding. The trial is testing it in pregnant women between 28 and 34 weeks of gestation.

Has this program been proven to work?

No. This is a protocol for a randomized controlled trial. That means the study has not been conducted or reported yet. There are no results, no safety data, and no evidence yet that the program helps. The trial will compare it to an active control program.

Who can join this study?

The trial plans to include 130 pregnant women between 28 and 34 weeks of gestation. It takes place online. The study is testing self-compassion and self-criticism as the main outcomes, along with postpartum depression, anxiety, quality of life, social support, and mother-infant bonding.

What are the side effects or risks?

The protocol does not report any safety information. Adverse events, serious adverse events, discontinuations, and tolerability are all listed as not reported. Because the trial has not been conducted or reported, there is no data yet on risks or side effects.

When will we know if it works?

The protocol does not say when results will be available. Measurements are planned at baseline, right after the 3-week program, and 3 months after birth. Until the trial is completed and reported, there is no way to know if the program helps.

BackgroundPerinatal mental health represents a significant public health concern given the high prevalence of mental disorders during pregnancy and the postpartum period and their impact on maternal well-being, mother-infant bonding, and child development. Emerging evidence identifies self-criticism as a transdiagnostic vulnerability factor associated with psychological distress in this period, while self-compassion has been recognized as an important protective factor. In Brazil, access to preventive perinatal mental health interventions remains limited. This paper describes the protocol of a randomized controlled trial (RCT) evaluating PROMATER – an online program designed to promote perinatal mental health by targeting self-criticism and self-compassion.MethodsA total of 130 pregnant women between 28 and 34 weeks of gestation will enroll in a two-arm RCT with a dismantling design. Participants will be randomized (1:1 ratio) to either the PROMATER intervention or to an active control group. Participants and data analysts will be blinded to group allocation. PROMATER consists of a 3-week program (6 modules) addressing maternal expectations, self-criticism, perinatal mental health, social support, self-compassion, and mindfulness and mother-infant bonding. The active control offers a structurally equivalent program covering the same topics, except for the modules specifically targeting these transdiagnostic processes. Primary outcomes are self-compassion, assessed via the compassionate self-responding (CSR) score of the Self-Compassion Scale, and self-criticism, operationalized through the uncompassionate self-responding (USR) score. Secondary outcomes include postpartum depression, anxiety, quality of life, social support, and mother-infant bonding. Assessments occur at baseline (T1), post-intervention (T2), and 3-month postpartum follow-up (T3). Data will be analyzed using Linear Mixed Models (LMM) following the Intention-to-Treat (ITT) principle.DiscussionEvaluating the effectiveness of a brief, accessible, online intervention has the potential to address the need for an evidence-based approach designed to promote maternal well-being during pregnancy and the postpartum period. The intervention is designed to maximize reach and minimize cost, with the potential to scale up and incorporate in routine perinatal care. The active control condition will allow examination of whether directly targeting self-criticism and self-compassion confers incremental benefit over structured perinatal psychoeducation alone.Systematic review registrationhttps://ensaiosclinicos.gov.br/, identifier RBR-99tjfz5.
