However, measurement properties of this questionnaire have not been evaluated in stroke survivors in African francophone countries where there is a lack of context-validated outcome measures. The aim of this study was to evaluate the construct validity and test-retest reliability of a Benin-adapted French version of the IPAQ Long form (IPAQ-Benin) in patients with stroke in Benin.Subjects and Method: Preliminary analyses were based on 38 stroke patients (27 males; mean age: 55.8u00b111.6 years old) recruited in Benin, a West-African country. In addition to a 7-day activity monitoring using a wrist-worn device, participants completed the interview-based IPAQ-Benin. They also completed ACTIVLIM-Stroke and ABILOCO-BENIN, two Rasch-built questionnaires previously validated in Benin for stroke-related activity limitations and locomotor ability, respectively. The IPAQ-Benin was completed twice over two days for test-retest reliability that was assessed through intra-class correlation coefficient (ICC). For construct validity, Pearson correlation coefficients (r) were calculated between IPAQ-Benin scores and 7-day steps, ACTIVLIM-Stroke and ABILOCO-BENIN scores.Results: The IPAQ-Benin showed excellent correlation with daily steps (r=0.94; p <.001) and moderate correlations with ACTIVLIM-Stroke (r=0.53; p <.001) and ABILOCO-Benin (r=0.50; p <.001). IPAQ-Benin demonstrated excellent test-retest reliability (ICC=0.99; CI95%: .98-.99; p <.001).Conclusion: These preliminary results suggest that IPAQ-Benin is a valid and reliable measure of physical activity in stroke patients. Further investigations on a larger sample are needed to confirm the psychometric properties of this French-version of the questionnaire in African contexts.KeywordstStrokePhysical activityQuestionnairemeasurement properties

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; both teacher heads agree on what is shown here.
