Insights
Very preterm/very low birthweight infants show higher rates of disorganised attachment. Neurodevelopmental issues, not maternal sensitivity, predict disorganised attachment in this group, unlike full-term infants.
Area of Science:
- Developmental Psychology
- Neonatal Research
- Attachment Theory
Background:
- Infant attachment security and disorganisation are crucial for social-emotional development.
- Very preterm/very low birthweight (VP/VLBW) infants face unique challenges impacting development.
- Understanding attachment pathways in VP/VLBW infants is vital for early intervention.
Purpose of the Study:
- Compare attachment security and disorganisation between VP/VLBW and full-term infants.
- Investigate differing pathways to disorganised attachment in these two groups.
Main Methods:
- Longitudinal study of 71 VP/VLBW and 105 full-term infants at 18 months using the Strange Situation Assessment.
- Assessed maternal sensitivity, mother-infant interaction, infant difficultness, and developmental status.
Main Results:
- Higher disorganised attachment rates in VP/VLBW (32%) vs. full-term (17%) infants.
- Maternal sensitivity predicted disorganisation in full-term infants.
- Infant distress and developmental delay, not maternal sensitivity, predicted disorganisation in VP/VLBW infants.
Conclusions:
- A significant proportion of VP/VLBW infants exhibit disorganised attachment.
- Neurodevelopmental problems are a key pathway to disorganised attachment in VP/VLBW infants.
- Disorganised attachment is common in VP/VLBW infants, even with sensitive parenting.
Objective:
To investigate whether there are differences in attachment security and disorganisation between very preterm or very low birthweight (VP/VLBW) (<32 weeks gestation or <1500 g birthweight) and full-term infants (37-42 weeks gestation) and whether the pathways to disorganised attachment differ between VP/VLBW and full-term infants.
Design:
The sample with complete longitudinal data consisted of 71 VP/VLBW and 105 full-term children and their mothers matched for twin status, maternal age, income and maternal education. Infant attachment was assessed with the Strange Situation Assessment at 18 months of age. Maternal sensitivity in the VP/VLBW and full-term samples was rated by neonatal nurses and community midwives in the neonatal period, respectively, and mother-infant interaction was observed at 3 months. Infant difficultness was assessed by maternal report at 3 months and infant's developmental status was assessed with the Bayley Scales (BSID-II).
Results:
Most VP/VLBW (61%) and full-term (72%) children were found to be securely attached. However, more VP/VLBW (32%) than full-term children (17%) had disorganised attachment. Longitudinal path analysis found that maternal sensitivity was predictive of attachment disorganisation in full-term children. In contrast, infant's distressing cry and infant's developmental delay, but not maternal sensitivity, were predictive of disorganised attachment in VP/VLBW children.
Conclusions:
A third of VP/VLBW children showed disorganised attachment. Underlying neurodevelopmental problems associated with VP/VLBW birth appear to be a common pathway to a range of social relationship problems in this group. Clinicians should be aware that disorganised attachment and relationship problems in VP/VLBW infants are frequent despite sensitive parenting.
