Abstract

Malgré quelques limites, le coefficient alpha de Cronbach reste l'indicateur de fidélité d'échelle le plus utilisé. Le but de cet article est de passer en revue l'ampleur des coefficients alpha obtenus dans les recherches comportementales empiriques, de confronter ces valeurs obtenues aux règles et aux recommandations préconisées par des chercheurs tels que Nunnally (1967, 1978), et d'apporter des éclairages sur les caractéristiques de plan de recherche susceptibles d'influencer la taille du coefficient alpha. Les moyennes des coefficients alpha rapportés dans la littérature vont de 0,70 pour les valeurs et les croyances, à 0,82 pour la satisfaction au travail. Hormis quelques exceptions, il n'existe aucune relation substantielle entre l'ampleur du coefficient alpha et les caractéristiques des plans de recherche examinés.
