In this study, we translated and localized the Adult Decision-making Competence scale (A-DMC) and tested its reliability and validity with large samples. Results show the Chinese A-DMC has relatively good reliability (Cronbach's alpha above 0.6 and test-retest reliability coefficients ranging from 0.44 to 0.78 on all subscales), comparable with the original version. Regarding validity, results of exploratory factor analysis and confirmatory factor analysis support the one-factor model, indicating the A-DMC has good internal consistency and construct validity. A-DMC scores correlated positively with cognitive ability, constructive decision-making styles, and good decision outcomes. Additionally, individuals with higher A-DMC scores were found to perform better on the Cambridge gambling task and Iowa gambling task. These results confirm the validity of the Chinese version of the A-DMC, which is suitable for measuring decision-making competence in Chinese adults.
