Psychometric Properties of the IPAQ: A Validation Study in a Sample of Northern Franco-Ontarians
Bibliographic record
Abstract
BACKGROUND: The International Physical Activity Questionnaire (IPAQ) has received significant attention since the late 1990s. As it currently stands, its long version has been translated in English, German, Icelandic, Korean, Polish, Spanish, Turkish, and Vietnamese. However no data originating from the self-administered long version (last 7 days) of the IPAQ (IPAQ-SALV) is available for French Canadians. This study developed a self-administered long version (last 7 days) of the IPAQ in Canadian French (IPAQ-SALVCF) and assessed its psychometric properties. METHODS: The original IPAQ-SALV was linguistically translated, back-translated, and then reviewed in a focus group to ensure its meaning had been retained. Data were collected on a sample of 34 Francophones from Northern Ontario, and the results compared with step counts assessed by 7-day pedometer recording. Test-retest reliability was examined with a 24-hour delay between questionnaire completion on day 8 and day 9 of the protocol. Convergent validity was assessed by comparing IPAQ-SALVCF (last 7 days) results to average step counts over a 7-day period. RESULTS: Intraclass correlation coefficients (ICC) revealed that the IPAQ-SALVCF results were stable between days. The ICC for total activity scores was highest at 0.93 (CI: 0.86 to 0.97). Total activity scores were also significantly related to pedometer step counts (Pearson r = .66 P < .01). These results confirm those obtained in prior research. CONCLUSION: The IPAQ-SALVCF is a reliable and valid measure of physical activity for French Canadians.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
