Hypothesis

This study aimed to assess the psychometric properties of the Korean translation of the PedsQL™ 4.0 Generic Core Scales.

Conclusion

The results demonstrate the feasibility, validity, item reliability, item fit, and agreement between child self-report and parent proxy-report of the Korean version of PedsQL™ 4.0 Generic Core Scales for school population health research in Korea.

Supporting Evidence

  • The PedsQL™ 4.0 has been linguistically validated in many languages.
  • Confirmatory factor analysis supported a four-factor model.
  • Child self-reports and parent proxy-reports showed moderate agreement.
  • Item reliability was high, but person reliability was low.
  • Ceiling effects were noted in the healthy population.

Takeaway

This study checked if a Korean version of a children's health questionnaire works well, and it found that it does, but some parts need more testing.

Methodology

The study involved translating the PedsQL™ 4.0 into Korean, conducting cognitive interviews, and analyzing responses from 1425 children and 1431 parents using confirmatory factor analysis and the Rasch model.

Potential Biases

Potential cultural differences and social desirability bias may have influenced responses.

Limitations

The sample was not representative of the Korean population, and the small number of children with chronic health conditions may not reflect the broader population.

Participant Demographics

The sample included 1453 parent-child dyads, predominantly healthy children (96.1%) with a mean age of 8-18 years, and a majority were girls (54.8%).
