Legami Prima della Nascita: Un Intervento di Salute Mobile per Coppie in Attesa del Primo Figlio (B³)

3 novembre 2026 aggiornato da: Michelle Kee, Institute for Human Development and Potential (IHDP), Singapore

Bonding Before Birth: Uno studio a grappoli randomizzato, controllato, basato su mHealth per sviluppare la consapevolezza e la regolazione emotiva nelle coppie in attesa

Emotional regulation is a key component of reducing parenting stress, a sense of self-efficacy, and thus successful parenting, child outcomes, and productivity amongst working parents. However, few interventions begin building these necessary components in pregnancy prior to the extremely stressful period immediately post-partum, where little trait and behavioural modification occurs. More importantly, most interventions overlook the importance of having both partners, despite fathers/partners playing a significant role in influencing maternal stress and mood symptoms.

This goal of this study is to examine whether short weekly exercises delivered through a mobile app can help first-time parents feel better emotionally during pregnancy. These exercises are designed to help people manage their emotions and stress. Researchers want to know if doing these exercises, along with getting weekly feedback and encouragement, can reduce signs of depression and improve emotional control.

Expecting mothers and fathers who are having their first child may be able to join the study if they meet certain conditions. Participants should be planning to stay in Singapore for the next two years and be comfortable using a smartphone and answering questions in English. Participants may benefit from learning new ways to manage stress and emotions, which could help improve their mental health.

Participants will wear a Fitbit watch to track activity. They will complete a short weekly survey about their well-being during pregnancy and a monthly survey about their work productivity until six months after the baby is born. They will also answer online surveys about their health, relationships, and background at the start, three times during pregnancy, and three times after birth. In addition, they will visit the research lab twice to take part in tasks that measure thinking and behaviour.

Descrizione dettagliata

The overall goal of this study is to answer the following main questions:

  • Does the intervention improve parents' depressive symptoms scores, using the Edinburgh Postnatal Depression Scale as a proxy?
  • Does the intervention improve parents' emotional regulation skills?

The study involves 286 expectant couples (572 individuals) in a two-arm, cluster-randomized controlled trial with longitudinal observational follow-up until the child turns 6 months old. The active intervention comprises of customized, weekly recommendations of short (2-5 minute) audio clips featuring activities such as breathing exercises, meditation, mindful walking. These will be provided to adult participants (expectant couples). Couples enrolling in the study will randomly be allocated to either the control or intervention group by prespecified block sizes of 10. That is, a random number generator will be used to preset the assignments in groups of 10, such that every 10 consecutive enrolments will have exactly 5 controls and 5 interventions (1:1 allocation). While it is not possible to blind operational staff to assignments (different protocols to follow, highly unbalanced assignment), scheduling of enrolment visits will be done by different staff than those conducting the enrolment visits, and the assignment will only be made known to enrolment staff while conducting the visit itself and they will also not have access to the blocking and randomization algorithm.

Participants in the control, no-intervention group will have access to a mobile app with similar functions as the participants in the intervention group, except that no personalized modules are given. Data will also be collected from online and in-app surveys, as well as via the Fitbit watch.

Participants in the intervention group will have access to the mHealth app that will be installed on their mobile devices and have access to weekly personalized recommendations. Participants will also be re-randomized weekly to different modules within the app. Data will also be collected from online and in-app surveys, as well as via the Fitbit watch.

The intervention will take place throughout pregnancy, beginning at enrollment ( when the mother is less than 20 gestational weeks of pregnancy), and continuing until the child is born. As gestational duration varies among participants, the total intervention period will range approximately from 17 to 28 weeks, depending on the timing of recruitment and delivery. All study arms will be assessed up to 6 months after birth.
