Tóm tắt :

La présente étude visait à examiner la validité et la fiabilité d'un questionnaire mis au point par des chercheurs, basé sur la TSC, et visant à évaluer le comportement de jeunes adolescentes iraniennes en matière d'activité physique. Les propriétés psychométriques du questionnaire de TSC pour l'activité physique dans un échantillon de jeunes élèves filles iraniennes ont été évaluées en déterminant sa validité apparente, sa validité de contenu et de construit, ainsi que sa fiabilité. Afin d'évaluer la structure factorielle du questionnaire, une étude transversale a été conduite auprès de 400 lycéennes à Téhéran. L'index et le radio de validité de contenu, ainsi que le score d'impact du questionnaire de TSC pour l'activité physique dans un échantillon de jeunes élèves filles iraniennes, variaient de 0,97 à 1, de 0,91 à 1 et de 4,6 à 4,9 respectivement. L'analyse factorielle confirmatoire a validé une structure factorielle comprenant 6 aspects : l'auto-efficacité, l'auto-régulation, le soutien familial, le soutien social, l'attente du résultat et l'auto-efficacité pour dépasser les obstacles. La saturation factorielle, les valeurs de t et les indices d'ajustement ont montré que le modèle d'évaluation de la TSC était adapté aux données. Le coefficient alpha de Cronbach était compris entre 0,78 et 0,85 et le coefficient de corrélation intraclasse entre 0,73 et 0,90 This research examined the validity and reliability of a researcher-developed questionnaire based on Social Cognitive Theory [SCT] to assess the physical activity behaviour of Iranian adolescent girls [SCT-PAIAGS]. Psychometric properties of the SCT-PAIAGS were assessed by determining its face validity, content and construct validity as well as its reliability. In order to evaluate factor structure, cross-sectional research was conducted on 400 high-school girls in Tehran. Content validity index, content validity ratio and impact score for the SCT-PAIAGS varied between 0.97-1, 0.91-1 and 4.6-4.9 respectively. Confirmatory factor analysis approved a six-factor structure comprising self-efficacy, self-regulation, family support, friend support, outcome expectancy and self-efficacy to overcoming impediments. Factor loadings, t-values and fit indices showed that the SCT model was fitted to the data. Cronbach's alpha-coefficient ranged from 0.78 to 0.85 and intraclass correlation coefficient from 0.73 to 0.90
