Maternal-infant mental health: postpartum group intervention

Area of Science:

• Perinatal mental health
• Developmental psychology
• Group psychotherapy

Background:

• Maternal depression and anxiety negatively impact infant attachment and perpetuate maternal mental illness.
• Existing individual and dyadic therapies are effective but resource-intensive.
• Novel, resource-efficient interventions are needed for maternal-infant mental health.

Purpose of the Study:

• To assess the feasibility, acceptability, and preliminary efficacy of a new maternal-infant dyadic group therapy.
• To evaluate the intervention's impact on maternal mood, insight, parenting, and mentalizing capacity.
• To determine the potential of this group intervention as a scalable mental health solution.

Main Methods:

• An open-label pilot study involving three 12-week maternal-infant dyadic groups for mothers with mood or anxiety disorders.
• Intervention combined evidence-based maternal and mother-infant dyadic strategies.
• Feasibility (recruitment, retention), acceptability (questionnaires, interviews), and efficacy (PSI, EDPS, BAI) were measured pre- and post-treatment.

Main Results:

• Excellent feasibility and acceptability were reported.
• Significant reduction in mean depressive symptom scores (p=0.008) and a trend toward decreased anxiety scores (p=0.08).
• Parenting Stress Index scores decreased, approaching statistical significance (p=0.057), with self-reported improvements in insight, parenting, and affect regulation.

Conclusions:

• The novel mother-baby dyadic group intervention is feasible, acceptable, and demonstrates good preliminary efficacy.
• The intervention shows potential for improving maternal depression, anxiety, affect regulation, parenting skills, and mentalization.
• This resource-efficient approach may offer a scalable solution for perinatal mental health challenges.
