Evaluating the Effectiveness of a Digital Therapy Intervention (iCARE) to Treat Symptoms of Postpartum Depression: study protocol for a two—armed randomized controlled trial
This study protocol outlines a two-arm randomized controlled trial designed to evaluate the effectiveness and safety of the self-guided internet-based cognitive behavioral therapy intervention iCARE compared to treatment as usual for reducing postpartum depression symptoms in Danish mothers.

Every year, millions of women experience a profound shift in their mental health after giving birth. This condition, known as postpartum depression, is characterized by persistent low mood, a loss of interest in daily life, and overwhelming fatigue. It is a common occurrence, affecting roughly one in ten mothers in wealthy nations, and if left untreated, it can linger for months, casting a shadow over the mother's well-being and the developing bond with her child. While psychological treatments like cognitive behavioral therapy are proven to help, access to these services is often uneven. In many places, long waiting lists, the stigma of seeking help, and the logistical difficulty of finding childcare prevent mothers from getting the support they need. This gap in care has led researchers to look toward digital solutions, wondering if a therapy delivered through a computer or smartphone could offer a flexible, accessible alternative that fits into the chaotic reality of new parenthood.
The study protocol detailed here outlines a major experiment designed to test exactly that. Researchers in Denmark are launching a large-scale trial to see if a self-guided digital program called iCARE can effectively treat symptoms of postpartum depression. The program is built on the principles of cognitive behavioral therapy, which helps people identify and change unhelpful thought patterns, but it also incorporates elements of acceptance and commitment therapy, a method that encourages individuals to accept difficult feelings while taking action aligned with their values. Unlike traditional therapy, which requires regular appointments with a clinician, iCARE is designed to be used independently by the mother at her own pace. The researchers are not testing this tool in a vacuum; they are comparing it against the standard care that mothers currently receive in their communities, which might range from a few visits with a health nurse to specialized psychological support, depending on where they live.
The trial involves 356 mothers who have given birth within the last six months and are showing signs of depression, but who are not in immediate need of emergency psychiatric care. These participants are recruited through health nurses who visit homes as part of routine postpartum care, as well as through a national website where mothers can sign up themselves. Once enrolled, the women are randomly assigned to one of two groups. One group receives the iCARE program in addition to whatever standard care they are already getting, while the other group receives only the standard care available to them. This design ensures that no mother is denied existing support, addressing ethical concerns while still allowing the researchers to see if the digital tool adds any extra benefit. The study is set to run for several years, with the first participants starting in early 2026.
The primary question the researchers hope to answer is whether the group using iCARE shows a greater reduction in depressive symptoms after two months compared to the group receiving only standard care. They measure these symptoms using a well-known screening tool called the Edinburgh Postnatal Depression Scale, which asks mothers to rate how they have been feeling over the past week. Beyond just the mood scores, the study also tracks changes in anxiety levels, the ability to function in daily life, the frequency of negative automatic thoughts, and the stress associated with parenting. Because the intervention is self-guided, the researchers are also paying close attention to safety. The program includes built-in checks that monitor the mother's scores; if a woman's symptoms worsen significantly or if she expresses thoughts of self-harm, the system flags this for immediate review, and the research team is prepared to connect her with professional help.
This project is more than just a test of a new app; it is an investigation into how mental health care can be delivered in the modern world. The researchers have worked closely with mothers who have experienced postpartum depression to ensure the program is easy to use and addresses real needs. They have also engaged with health nurses and patient organizations to make sure the study fits smoothly into the existing healthcare system. If the results show that iCARE is effective, it could provide a scalable way to reach mothers who might otherwise go without treatment, potentially changing how mental health support is integrated into routine postpartum care. However, the study is currently in the planning and recruitment phase, and the final results regarding its effectiveness and safety are yet to be determined. The hope is that by the time the trial concludes, the findings will offer clear evidence on whether a digital, self-guided approach can successfully bridge the gap in care for mothers struggling with depression.
