title: Modification of the Edinburgh Handedness Inventory: a replication study.
abstract: The Edinburgh Handedness Inventory was administered to 1224 high school students (605 males and 619 females). Confirmatory factor analysis was used to re-examine its psychometric properties. The results showed that this instrument has poor measurement properties. Removal of a few problematic items improved internal consistency of the questionnaire and improved its validity. The results also suggest that the impact of modification did not affect classification of individuals into left- and right-handedness categories but did influence classification of mixed-handers with the original version classifying significantly more individuals into mixed-handedness category than the modified version.
