The Validity and Reliability of a School-Based Physical Activity Opportunities Survey
Bibliographic record
Abstract
This article outlines the development of a physical activity opportunities survey intended to assess perceptions of school staff and parents relative to factors associated with school-based physical activity opportunities. A secondary aim was to construct a valid and reliable tool that would be relevant across Canadian school contexts. Survey validity was determined through completion of the online survey by parents, teachers, and administrators from elementary, middle, and secondary schools. Several participants agreed to take the survey a second time for reliability purposes. Results indicated the best-fit model to be 19 items constrained by three factors: school policies and practices, school artifacts, and parent involvement in physical activity promotion. Test-retest analysis revealed strong reliability (intraclass correlation coefficient = .783, p < .05). Therefore, the survey is a viable aid towards identifying factors in school environments that contribute to or impede the offering of school-based physical activity opportunities. Cet article decrit l’elaboraton d’un sondage sur les facteurs associes aux occasions de pratique d’activite physique en milieu scolaire, a partir de la perception du personnel et des parents. Un objectif secondaire consistait a produire un outil valide et fiable qui pourrait servir a toutes les ecoles canadiennes. Pour etablir la validite du sondage, des enseignants, des administrateurs scolaires et des parents d’ecoles elementaires, intermediaires et secondaires ont rempli un un sondage en ligne. Plusieurs ont accepte de participer une deuxieme fois au sondage pour verifier la fiabilite. Les resultats revelent que le modele de sondage le plus pertinent comporte 19 elements constitutifs de trois facteurs : les politiques et pratiques de l’ecole, les artefacts de l’ecole et la participation des parents a la promotion de l’activite physique. L’analyse du sondage et du sondage secondaire indique que le degre de fiabilite est eleve (coefficient de correlation interclasses = ,783, p < ,05). Le sondage constitue un outil viable pour cerner les facteurs qui contribuent positivement ou negativement a la creation d’occasions de pratique d’activite physique dans un contexte scolaire.

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.
