Insights
The Mother-Infant Transaction Program (MITP) did not alter long-term mother-child adaptation in preterm children. However, MITP mothers showed weaker stress-behavior links, particularly for attentional issues, influenced by birth weight and maternal education.
Area of Science:
- Child Psychology
- Developmental Psychology
- Maternal Health
Background:
- The Tromsø Intervention Study on Preterms (TISP) previously showed benefits of the Mother-Infant Transaction Program (MITP) for preterm infants and mothers.
- Longitudinal adaptation and the interplay between maternal stress and child behavior problems require further investigation.
Purpose of the Study:
- To examine the longitudinal impact of the MITP on mother-child adaptation from ages two to nine years.
- To analyze associations between child behavioral problems and maternal parenting stress over time within the TISP cohort.
Main Methods:
- Longitudinal analysis of data from 146 preterm-born children and their mothers randomized to MITP or a control group.
- Statistical modeling to assess interactions between parenting stress, group status (MITP vs. control), and time on child behavior problems.
- Examination of moderating effects of birth weight and maternal education on stress-behavior associations.
Main Results:
- No significant three-way interaction (stress*group*time) was found, indicating MITP did not alter the development of longitudinal stress-behavior associations.
- Significant stress by group interactions were observed for children's attentional problems, with MITP mothers reporting weaker associations.
- The effect of MITP on stress-behavior associations was moderated by birth weight and maternal education for parent-child difficult interaction stress.
Conclusions:
- The MITP did not significantly influence the longitudinal trajectory of mother-child adaptation concerning stress and behavior problems.
- MITP participation was associated with diminished links between maternal stress and child behavior, especially attentional issues, suggesting a potential benefit in specific contexts.
- Maternal education and child birth weight play a role in moderating the relationship between parenting stress and child behavior in the context of the MITP intervention.
Abstract:
The Tromsø Intervention Study on Preterms (TISP) randomized 146 preterm-born children either to the Mother-Infant Transaction Program (MITP) or to a preterm control group. Previously, significant reductions of child behavior problems and maternal stress have been reported in the intervention group. This follow-up study examines whether the MITP may have affected the longitudinal adaptation between mothers and their children from two until nine years, expressed as associations between different behavioral problems and parenting stress reported by mothers. Associations between internalizing, attentional, and social problems and different dimensions of parenting stress were analyzed in separate models that included effects of time and group status. The MITP did not influence the development of longitudinal associations as no significant three-way interaction (stress*group*time) was found. Significant stress by group interactions was only found in reports on children's attentional problems when analyzed with parent- or interaction-related stress. Mothers who had participated in the MITP reported weaker stress⁻behavior associations than control mothers. This effect was moderated by two independent variables, namely children's birthweight and years of maternal education for the parent⁻child difficult interaction stress.
