A smartphone app effectively facilitates mothers' mind-mindedness: A randomized controlled trial

Area of Science:

• Developmental Psychology
• Maternal Mental Health
• Digital Health Interventions

Background:

• Mind-mindedness is crucial for infant socio-emotional development.
• Early parent-infant interactions shape long-term developmental trajectories.
• Digital tools offer scalable solutions for parental support.

Purpose of the Study:

• To evaluate the efficacy of the BabyMind© smartphone application in enhancing maternal mind-mindedness.
• To assess the impact of the intervention on the quality of maternal mind-related comments.
• To investigate the potential of digital interventions in early childhood development.

Main Methods:

• A randomized controlled trial was conducted with mothers and their 6-month-old infants (N=152).
• Participants were assigned to either the BabyMind© app intervention or an active control group.
• Maternal mind-mindedness was assessed via mind-related comments at 12 months of infant age.

Main Results:

• Mothers in the BabyMind© group exhibited significantly higher appropriate mind-related comments (d=.61).
• The intervention group also showed significantly lower non-attuned mind-related comments (d=-.55).
• Findings remained consistent after adjusting for missing data.

Conclusions:

• The BabyMind© app intervention effectively enhanced maternal mind-mindedness.
• Smartphone applications can be a viable tool for early childhood interventions.
• Further research is needed to explore the app's efficacy in diverse populations.
