Insights
Early childhood problems like undercontrolled and internalizing issues show distinct developmental paths. Child temperament and family factors significantly influence these trajectories from 18 months onward.
Area of Science:
- Developmental Psychology
- Child Psychiatry
- Behavioral Science
Background:
- Childhood behavioral problems are a significant concern.
- Understanding developmental trajectories is crucial for early intervention.
- Early identification of risk factors can inform preventative strategies.
Purpose of the Study:
- To examine the developmental trajectories of undercontrolled and internalizing problems in young children.
- To identify early child temperament and family factors predicting these trajectories.
- To investigate the lasting effects of early risk factors on problem development.
Main Methods:
- Longitudinal study using growth curve modeling.
- Population-based sample of 921 Norwegian children.
- Data collected from 18 months to 4.5 years of age.
Main Results:
- Undercontrolled problems decreased, while internalizing problems increased with age.
- Early child temperament and family factors predicted stability and change in problem behaviors.
- Lower partner support and higher child emotionality predicted increased undercontrolled problems.
- Higher family stress predicted increased internalizing problems.
Conclusions:
- Undercontrolled and internalizing problems follow distinct developmental pathways from early ages.
- Early experiences and risk factors have persistent effects on problem development.
- A dynamic approach considering changes in risk factors is essential for analyzing child behavior problems.
Abstract:
Using growth curve modeling, trajectories of undercontrolled (oppositional, irritable, inattentive and overactive behaviors) and internalizing (worried, sad and fearful) problems from 18 months to 4.5 years were studied in a population based sample of 921 Norwegian children. At the population level, undercontrolled problems decreased and internalizing problems increased with increasing age. Child temperament and family factors present at 18 months predicted 43% of the stability and 20% of the linear changes in undercontrolled problems and 30% of the stability and 7% of the linear changes in internalizing problems. Persisting effects of child and family factors from 18 month were found on the two problem dimensions over and above the impact of changes in the same risk factors. Lower initial level of partner support and higher initial level of child emotionality predicted higher slope of undercontrolled problems and higher initial level of family stress predicted higher slope for internalizing problems. As expected, time to time change (t1 to t2 and t2 to t3) in risk factors predicted time to time change in problem scores as well. The study shows the significance of early emerging internalizing and undercontrolled problems, the need to consider their pathways separately from very young ages, lasting effects of early experiences, and the importance of a dynamic approach to the analysis of risk.
