The Stability of Problem Behavior Across the Preschool Years: An Empirical Approach in the General Population

Area of Science:

• Developmental Psychology
• Child Psychiatry
• Behavioral Science

Background:

• Understanding the developmental trajectory of child problem behaviors is crucial for early intervention.
• Internalizing and externalizing problems can manifest differently across early childhood.
• The stability and presentation of behavioral issues in preschoolers require further investigation.

Purpose of the Study:

• To examine the stability of internalizing and externalizing problems from 1.5 to 6 years of age.
• To analyze developmental changes in the presentation of child problem behaviors.
• To identify predictors of persistent problem behaviors in early childhood.

Main Methods:

• Population-based cohort of 7,206 children studied from 1.5 to 6 years.
• Mothers reported on child problem behavior using the Child Behavior Checklist/1.5-5 (CBCL/1.5-5) at ages 1.5, 3, and 6.
• Latent profile analysis and latent transition analysis (LTA) were used to assess problem behavior profiles and their stability.

Main Results:

• Problem behavior profiles varied across ages, with 82-87% of children showing no significant problems.
• A profile of co-occurring internalizing and externalizing problems was present in approximately 2% of children and became more severe by age 6.
• Predicting specific problem profiles at age 6 based on earlier data was challenging; however, children with early co-occurring problems were most likely to persist.

Conclusions:

• The presentation of problem behavior evolves throughout the preschool years, with heterotypic continuity being common.
• Children exhibiting co-occurring internalizing and externalizing problems early in life face a higher likelihood of persistent behavioral issues.
• Early identification and evidence-based treatment for young children with co-occurring problems may prevent long-term psychiatric conditions.
