「設計流暢性測驗平板版」的信、效度研究曁本土常模建置

Design Fluency Test (DFT) is an assessment for evaluating the performance of the frontal lobes. The Design Fluency Test of the famous Delis-Kaplan Executive Function System (D-KEFS) has been widely used, and is applicable to a wide range of subjects, from gifted individuals to severely brain-damaged patients. However, the scoring method for this test is relatively laborious. Based on D-KEFS-DFT, the present study develops an electronic version-the Tablet-Based Design Fluency Test (TB-DFT)-and inspect its psychometric characteristics. TB-DFT is divided into three conditions: condition 1 (fluency), condition 2 (fluency + inhibition), condition 3 (fluency + switching); the number of "correct design" reflects the score of condition. Through the comparison between conditions, we calculate three scoring indicators of fluency, inhibition and switching. 1,099 participants in aged 8-29 were recruited from different areas in Taiwan to exam the reliability and validity of this test. In the reliability, the three conditions of TB-DFT have great test-retest reliability. Furthermore, this test has great internal correlation, and the three scoring indicators also reflect the relative ability. In the criterion- related validity, there is a significant positive correlation between the "fluency" indicator and updating ability, reaction time, and figural reasoning. In the discriminant validity, the "switching" was also significantly positively correlated with card sorting tasks involving conversion ability. This indicates that the test has good validity, and "fluency" and "switching" are scoring indicators that can be effectively and independently assessed. In addition, there was no significant difference between genders, but performance would gradually increase with age until it became stable in high school; this study further established the norm of cognitive development to cognitive stability stage (Aged 8-29). This study provides effective measurement. It is expected to deepen the exploration of design fluency and executive function.
