Summary
Maternal traumatic stress impacts mother-infant interaction quality, especially in preterm infants. Early maternal sensitivity and control at 6 months are affected by perinatal stress and infant risk factors.
Area of Science:
- Developmental Psychology
- Perinatal Mental Health
- Maternal-Infant Interaction
Background:
- Premature birth and infant immaturity can negatively affect parent-child relationship quality.
- Limited research exists on the link between maternal stress and parent-infant interaction dynamics.
Purpose of the Study:
- To investigate the relationship between maternal and infant interactional behavior over time.
- To examine the influence of infant perinatal risk factors and maternal perinatal traumatic experiences on this interaction.
Main Methods:
- Longitudinal study of 47 preterm and 25 full-term infants, with mother-child interactions recorded at 6 and 18 months.
- Maternal interactional behavior coded for sensitivity, control, and unresponsiveness; infant behavior for cooperation, compliance, difficulty, and passivity.
- Maternal stress assessed using the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ); infant risk factors using the Perinatal Risk Inventory (PERI).
Main Results:
- Mothers reporting high perinatal stress or having high-risk infants showed less sensitivity and more controlling behavior at 6 months.
- Preterm infants exhibited different interactional behaviors than full-term infants at 18 months.
- Infant interactional behavior at 18 months correlated with maternal traumatic stress, but not with perinatal risk factors.
Conclusions:
- Maternal traumatic experiences during the perinatal period significantly influence mother-child interaction.
- These effects on interactional behavior can have long-lasting implications, particularly in the context of premature birth.
