Assessing decision-making style in French-speaking populations: Translation and validation of the general decision-making style questionnaire

IntroductionIndividual differences in decision-making are a fundamental component of our understanding of the decision-making process. Scott and Bruce (1995) developed the General Decision-Making Style (GDMS) questionnaire to assess five decision-making styles: rational, intuitive, dependent, avoidant, and spontaneous.ObjectiveThe purpose of our study was to translate and validate the GDMS into French. This measure has been used frequently to assess decision-making style since its creation. Yet, the scale is currently unavailable in French despite being already available in Slovak, Italian, and Swedish.MethodFollowing best practices for scale translation (e.g., Vallerand, 1989), the original version of the GDMS was administered to a group of 345 English-speaking participants and the translated version of the questionnaire was administered to a group of 325 French-speaking participants.ResultsThe properties of the translated questionnaire were then compared to those of the original questionnaire. Results of item-level, scale-level and measurement invariance analyses demonstrate that the translated measure, the Échelle des styles décisionnels, is a valid and reliable assessment of decision-making style in French-speaking populations.ConclusionThis measure already exists in languages that are much less commonly spoken than French. The newly translated Échelle des styles décisionnels will now allow researchers to validly assess decision-making style in French-speaking populations, thereby greatly increasing the ability to assess cross-cultural stability of decision-making theories.
