Korean Children's Smartphone Dependency and Happiness, 2018-2021

Longitudinal data from 1,889 Korean children tracked from ages 9 to 13 shows a consistent negative correlation between smartphone dependency and happiness. The dataset comprises four waves (2018–2021) of the nationally representative Korean Children and Youth Panel Survey (KCYPS). Minsol Kim analyzed the data using latent growth modeling, revealing less favorable happiness trajectories associated with higher smartphone dependency.

Use Cases

• Modeling longitudinal trends in children's emotional well-being based on repeated measures over four years.
• Analyzing the correlation between technology use and happiness scores mentioned in the study.
• Applying latent growth modeling to panel survey data to understand developmental trajectories.

Strengths

• Nationally representative cohort of 1,889 fourth-grade students.
• Longitudinal data spanning four waves from 2018 to 2021.
• Analysis includes latent growth modeling, a sophisticated statistical technique.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 5.5 KB file size suggests a very limited scope, likely containing summary statistics rather than raw survey responses.
