Summary
This study introduces the Family Level Assessment of Screen Use (FLASH)-mobile approach, a new method for accurately measuring children's mobile device screen time. The FLASH-mobile approach shows promise for improving research on children's digital habits.
Area of Science:
- Pediatric digital health
- Human-computer interaction
- Child development
Background:
- Increased mobile device use in children is linked to negative health and academic outcomes.
- Current screen time measurement methods (self-report, parent-proxy) are often imprecise or biased.
- Accurate measurement of children's screen time is crucial for understanding its impact.
Purpose of the Study:
- To evaluate the feasibility of the Family Level Assessment of Screen Use (FLASH)-mobile approach for measuring children's mobile device screen time.
- To leverage Android platform features for an innovative screen time measurement method.
- To assess the usability and accuracy of the FLASH-mobile approach in diverse settings.
Main Methods:
- Pilot study involving 48 parent-child dyads (ages 6-11) in laboratory and home settings.
- Utilized the FLASH-mobile approach on Android devices, comparing results to a gold standard (video coding).
- Collected qualitative feedback from parents and children on the approach's utility and potential improvements.
Main Results:
- FLASH-mobile achieved high compliance rates (>90% smartphones, >80% tablets) for user identification.
- Mean agreement of 73.6% was observed between FLASH-mobile and the gold standard in laboratory settings.
- Parents found the approach useful for tracking time and app usage, though privacy concerns were noted.
Conclusions:
- The FLASH-mobile approach provides a novel and more accurate method for measuring children's mobile device use over extended periods.
- This method is effective even when devices are shared within families.
- Further validation and enhancement of FLASH-mobile can significantly advance research in pediatric screen time measurement.
