Edinburgh Handedness Inventory – Short Form: A revised version based on confirmatory factor analysis

摘要: While the Edinburgh Handedness Inventory has been widely used, there have few studies assessing its factorial validity. There is evidence that original instructions and response options are difficult to understand. Using simplified options, was administered on a sample of 1514 participants using an online questionnaire. In accordance with previous research, model 10-item inventory had poor fit for data. This study also detected misspecification in previously-proposed 7-item modification. A 4-item - Short Form good items modelled as both continuous ordinal. Despite brevity, it showed very reliability, factor score determinacy, correlation scores inventory. By eliminating were considerable measurement error, short form alleviates concern over-categorising mixed handers. Evidence found invariance across level education, age groups, regions (USA Australia/New Zealand). generally appeared be genders The proposed measures single handedness brief simple small number items.
