Questionnaire d'efficacité de la consultation : élaboration et validation préliminaire d'une échelle de mesure de l'efficacité de la consultation en gestion

Despite sustained interest of both researchers and practitioners in favor of a reliable measure of management consulting effectiveness, the existing assessment instruments remain scarce, poorly validated and often inadequate. This study proposes a new instrument for assessing management consulting effectiveness from the consultant's point of view: The Consulting Effectiveness Questionnaire (Questionnaire d'efficacité de la consultation). The preliminary empirical validation of the questionnaire was conducted using two samples of 116 and 207 consultants. Exploratory and Confirmatory factor analyses suggests a second-order two-factor solution, namely the Quality of the process and Value-added results. The results offer preliminary support for the psychometric properties (validity and reliability) of this promising tool for both research and practice purposes.
