Insights
Very preterm children with early cognitive deficits face peer relationship challenges. Positive parent-infant relationships can mitigate these long-term peer problems.
Area of Science:
- Developmental Psychology
- Pediatrics
- Social Neuroscience
Background:
- Peer relationships are crucial for social-emotional development.
- Very preterm/very low birth weight (VP/VLBW) individuals may experience difficulties in social functioning.
- Longitudinal studies are needed to understand the developmental trajectories of peer relationships in VP/VLBW populations.
Purpose of the Study:
- To identify distinct developmental trajectories of peer relationships (peer acceptance, friendships, peer problems) from childhood to adulthood.
- To examine early-life predictors, including VP/VLBW status and parent-infant relationship quality, of these peer relationship trajectories.
Main Methods:
- Prospective longitudinal study of 218 VP/VLBW and 220 term-born individuals from birth to 26 years.
- Latent profile analysis to identify peer relationship trajectories based on parent and self-reports.
- Logistic regression analyses to assess predictors such as cognitive abilities and parent-infant relationship quality.
Main Results:
- Three trajectories for peer acceptance and friendships, and two for peer problems were identified.
- Higher cognitive abilities at 20 months predicted more optimal trajectories in peer acceptance, friendships, and fewer peer problems.
- A positive parent-infant relationship at 5 months predicted trajectories with fewer peer problems.
Conclusions:
- Early cognitive abilities are significant predictors of long-term peer relationship success.
- Interventions supporting positive parent-infant relationships may buffer against peer relationship difficulties in very preterm children.
- Findings highlight the importance of early cognitive development and supportive relationships for social adjustment in VP/VLBW individuals.
Objective:
To identify trajectories of peer relationships in very preterm and term-born individuals from 6 to 26 years of age and test early-life predictors of these trajectories.
Method:
As part of the Bavarian Longitudinal Study, 218 very preterm/very low birth weight (VP/VLBW; <32 weeks' gestation/<1500 grams) and 220 healthy term-born (37-42 weeks' gestation) individuals were followed prospectively from birth to adulthood. Parent and self-reports at 6, 8, 13, and 26 years were combined into comprehensive developmentally appropriate scores across 3 domains: peer acceptance, friendships, and peer problems. Latent profile analyses were used to identify trajectories across these 3 domains. Binary and multinomial logistic regressions were used to test the following potential predictors of trajectories: VP/VLBW status, sex, socioeconomic status, neonatal medical risk, parent-infant relationship at 5 months, child inhibitory control at 20 months, and child cognitive abilities at 20 months.
Results:
Three trajectories were identified for peer acceptance and friendships, and 2 trajectories were identified for peer problems. Higher cognitive abilities predicted more optimal trajectories in peer acceptance (odds ratio: 1.03 [95% confidence interval = 1.01-1.05]), friendships (1.03 [1.00-1.05]), and peer problems (1.06 [1.04-1.09]). In addition, good parent-infant relationships predicted lower peer problem trajectories (1.61 [1.03-2.50]).
Conclusion:
Early cognitive deficits may underlie persistent peer relationship difficulties in VP/VLBW samples. Positive parent-infant relationships may help reduce preterm children's risk for long-term peer problems.
