Executive Dysfunction Trajectories in Korean Children

2015 to 2018 longitudinal data from the Korean Child Panel Study tracks executive dysfunction in 1,196 children aged 8–11. Soo Eun Chae analyzed the dataset using a Latent Growth Model, finding a quadratic trajectory and comparing outcomes for children with and without psychosocial disabilities. The dataset includes 1,174 children without psychosocial disorders and 22 with such disorders.

Use Cases

• Model executive dysfunction score trajectories over time using age as a repeated measure.
• Compare average executive dysfunction levels between children with psychosocial disorders (N=22) and without (N=1,174) using repeated measures ANOVA.
• Analyze the interaction effect between psychosocial disability status and time on executive dysfunction scores.
• Apply Bayesian repeated measures analysis to address the small sample size of the psychosocial disorders group.

Strengths

• 1,196 valid longitudinal responses from a national panel study.
• Data collected over a 4-year period (2015-2018) enables growth modeling.
• Clear comparison groups defined: 1,174 children without psychosocial disorders and 22 with disorders.

Limitations

• Extremely small sample size for the psychosocial disorders group (N=22).
• Dataset is very small (5.5 KB), indicating limited scope and likely only summary or model results.
• Geographic coverage is limited to South Korea.
