Hypothesis
The study aims to compare different sampling and questionnaire administration methods in the KIDSCREEN study regarding participation, response rates, and external validity.
Conclusion
School-based sampling achieved the highest response rates but produced slightly more biased samples than other methods.
Supporting Evidence
- Response rates by country ranged from 18.9% to 91.2%.
- School-based surveys had the highest response rates (69.0%–91.2%).
- Parents in lower educational categories were less likely to participate.
- Samples were generally similar to the Eurostat reference population.
Takeaway
The KIDSCREEN study looked at how different ways of asking kids about their health affected how many kids answered the questions. They found that asking kids in schools got the most answers.
Methodology
Children and adolescents aged 8–18 were surveyed in 13 European countries using various sampling methods, including telephone and school-based surveys.
Potential Biases
Parents with lower educational levels were less likely to participate, potentially biasing the sample.
Limitations
Results may not be generalizable beyond the countries studied, and there may be confounding between countries and different sampling approaches.
Participant Demographics
Mean age of children was 9.7 years, with 51.3% female; mean age of adolescents was 14.4 years, with 53.8% female.
