简要总结
This study will provide data for evaluating the psychometric characteristics of the tests assessing cognitive flexibility, including their (1) internal consistency, (2) feasibility and tolerability, their (3) convergent and discriminant validity of cognitive and affective constructs such as those introduced to understand mental disorders, and (4) sensitivity (and correspondence) to individual differences. For these tests to be useful in studying clinical conditions, they must show adequate reliability, validity, and sensitivity in large samples of convenience.
