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 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.
