A psychometric evaluation of the General Decision-Making Style Inventory

The psychometric characteristics of Scott and Bruce’s [Scott, S. G., & Bruce, R. A. (1995). Decision making style: The development and assessment of a new measure. Educational and Psychological Measurement, 55(5), 818–831] General Decision-Making Style (GDMS) measure were examined using a sample of 223 management undergraduates from eight classes. Participants also completed the Marlowe–Crowne Social Desirability scale and several classes completed the values scale [Fitzsimmons, G., Macnab, D., & Casserly, C. (1985). Technical manual for the Life Roles Inventory Values Scale and the Salience Inventory. Edmonton, Alberta: PsiCan Consulting] or the Conflict-Management Styles inventory [Flynn, R., & Elloy, D. (1987). Conflict management. National Institute for Dispute Resolution. Washington, DC. Working paper]. Overall, results from the item and scale analyses support the construct validity of this new measure. Further validation work is recommended; for example, applying the GDMS in cross-cultural settings.
