Developing a Korean Version of the Physical Activity Questionnaire for Older Children
Bibliographic record
Abstract
A few standardized questionnaires are currently available for measuring physical activity among Korean children. The Physical Activity Questionnaire for Older Children (PAQ-C) has been supported as a valid and reliable measure of general physical activity levels among children. The purpose of this study was to test the reliability of a Korean translation of the PAQ-C. A convenience sample of 21 boys and 27 girls (ages 8-14, grades 3-9) was recruited from a Korean school and two Korean churches in Edmonton Alberta, Canada. To be included in the study, children needed to be able to read both Korean and English. Children were asked to complete both a Korean and English version of the questionnaire, one week apart. A significant test-retest correlation between the Korean and English versions of the PAQ-C was found (rtotal = 0.79, rboys = 0.80 and rgirls= 0.78). Statistically significant relationships existed between the two time points for all items on the questionnaires (ranging from r = 0.51 to 0.83, p < 0.01). In summary, the Korean version of the PAQ-C appears to be a reliable measure of physical activity. The results of this study will allow physical activity levels to be more accurately assessed among children in Korea.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
