Abstract

Individuals make decisions in different styles. The Decision-Making Style (DMS) influences personal development and predicts important clinical indicators. This research aimed to adapt and validate the Melbourne Decision-Making Questionnaire (MDMQ) in the Moroccan context. This questionnaire allows us to identify four DMSs: vigilance, buck-passing, procrastination, and hypervigilance. The factor analysis confirms the four dimensions proposed by the authors of MDMQ. The internal consistency and means of the four DMSs obtained are almost identical to those obtained in previous studies. The intercorrelations of the subscales are consistent with the four-factor theoretical model of Jannis and Mann’s conflict theory of decision-making. The psychometric characteristics obtained from this study justify the applicability of the MDMQ to Arabic-speaking young adults in Morocco. This measure may be applied in a variety of disciplines, including education and management.
