Sibling smartphone addiction significantly impacts child smartphone addiction over time. Early interventions should consider sibling dynamics to mitigate risks and progression of excessive smartphone use in children.
Area of Science:
- Child Psychology
- Behavioral Science
- Digital Health
Background:
- Global rise in child smartphone addiction linked to mental, physical, familial, and financial issues.
- Limited research on the longitudinal impact of sibling smartphone addiction on child smartphone addiction.
- Siblings are significant family influences during childhood development.
Purpose of the Study:
- To longitudinally explore the impact of sibling smartphone addiction on child smartphone addiction.
- To examine how sibling smartphone addiction influences the onset and progression of child smartphone addiction over time.
Main Methods:
- Longitudinal analysis of four years of panel data (2019-2022) from the Korean Children and Youth Panel Survey (KCYPS).
- Included 1,978 participants: 989 fourth-grade elementary school children and their siblings.
- Latent growth analysis used to examine changes in smartphone addiction.
Main Results:
- Both child and sibling smartphone addiction increased over time; higher initial sibling addiction predicted greater child addiction.
- The rate of change in sibling smartphone addiction significantly influenced the rate of change in child smartphone addiction.
- Lower initial smartphone addiction levels were associated with a greater increase in usage over time, suggesting targeted interventions.
Conclusions:
- Sibling smartphone addiction has a significant longitudinal impact on child smartphone addiction.
- Interventions for child smartphone addiction should incorporate sibling dynamics and long-term perspectives.
- Addressing sibling smartphone addiction is crucial for preventing and managing child smartphone addiction.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
