Abstract |
|
|
| This study examines the psychometric properties of the Arabic version of the Executive Function Index (EFI-
ARABIC). The sample consisted of 3220 participants aged between 17 and 84 years. The results indicated that the EFI- ARABIC demonstrated acceptable levels of internal consistency, ranging from 0.53 to 0.72 for the subscales and 0.76 for the total score. The correlation coefficients between the items and subscales ranged between 0.364 and 0.732, the correlation coefficients between the items and EFI-ARABIC total score ranged between 0.105 and 0.483, and the correlation coefficients between the subscales and EFI-ARABIC total score ranged between 0.438 and 0.764. The resulting 5-factor solution accounted for a 48% variance. Males scored higher in motivational drive, while females scored higher in strategic planning, impulse control, and total score. Moreover, as age and level of education increased, executive functions increased. In this
regard, similarities and differences emerged compared to previous studies. |
