Development and Validation of a Computer-based Decision-Making Task (CDMT) to Measure Decision-Making

Abstract

Background: Decision-making and its processes are the most important and most advanced levels of human cognitive abilities. Objectives: This study aimed to develop and validate a task-based decision-making tool. Methods: After constructing the computer-based decision-making task, 232 individuals with high and low impulse disorders were selected using cluster analysis based on the scores of impulsivity and sensation seeking. In the next step, the task-based decision-making tool was performed individually on the participants. In order to determine the psychometric properties of the task-based decision-making tool, the validity of this tool was investigated by comparing the groups with high and low impulse disorders in the dimensions of decision-making, and criterion validity was investigated with impulsivity and sensation seeking scale, self-responsibility, and decision-making styles. Results: The results of the comparison of individuals with impulse disorder represented the optimal discriminant validity of the task-based decision-making tool. The criterion validity with other measures indicated the good convergence and divergence validity of the tool. Conclusions: Overall, the findings suggested the task-based decision-making tool had good psychometric properties to be used in studies of assessing the overall decision-making.
