Abstract

Objectives

The purpose of this paper was to investigate the psychometric properties of a newly-designed scale intended to measure the perceived attributes of a Health Promoting School initiative and its context in terms of factor structure, reliability and predictive validity. The scale was developed to explore possible predictors of the adoption of the Healthy School approach (HS) in Québec.

Methods

Data were gathered from a 2007 cross-sectional study of 107 schools and 141 participants (school principals and school health promotion delegates). The scale was based on 7 attributes borrowed from the theories on diffusion of innovation. The factor structure of the scale was tested by exploratory and confirmatory factor analyses.

Results

The final scale included 14 items capturing 4 factors: school contextual barriers, collective efficacy, anticipated benefits and relative advantages. Reliability, in terms of internal consistency of the factors, ranged from a high of 0.85 to a low of 0.60. Three of the 4 factors significantly predicted HS adoption.

Conclusion

Overall, the scale showed good psychometric properties and may be useful to assess the attributes that could influence the adoption of this type of initiative.

Résumé

Objectifs

L’objectif de cet article est de présenter les qualités psychométriques d’un nouvel indice mesurant les attributs perçus d’une approche École en santé (AÉS), en termes de structure factorielle, de fidélité et de validité prédictive.

Méthodes

Les données proviennent d’une enquête postale menée à l’automne 2007 auprès de 107 écoles du Québec et de 141 participants scolaires (directeurs et responsables de la promotion de la santé). La théorie de la diffusion de Rogers ainsi que d’autres écrits sur la diffusion des innovations ont servi à la construction de l’indice. Deux analyses, exploratoire et confirmatoire, ont permis de tester la structure factorielle de l’indice.

Résultats

L’indice obtenu inclut 14 items répartis en 4 facteurs: contraintes dans l’environnement scolaire, efficacité collective, bénéfices anticipés et avantages relatifs. La consistance interne de ces facteurs varie entre,85 et,60. Les trois premiers facteurs ont permis de prédire l’adoption de l’AÉS.

Conclusion

Globalement, l’indice possède de bonnes qualités psychométriques et peut s’avérer utile pour évaluer l’influence des attributs de ce type d’approche sur son adoption par les écoles.
