Short Description of Instrument
The Edinburgh Handedness Inventory is a measurement scale used to assess the dominance of a person's right or left hand in everyday activities, sometime referred to as laterality. This instrument measure intellectual ability and motor function constructs.
This task should be included in every neuroimaging study. It is essential to interpret neuroimaging results.
The 4-item version of the Edinburgh Handedness Questionnaire has good psychometric properties and places a  reduced burden on patients and research participants.
"A ten-item questionnaire designed to assess handedness by self-report of the preferred hand for carrying out common activities such as writing and drawing, throwing, and using utensils such as a toothbrush, knife, and spoon. Subjects place 1 or 2 check marks under "left" or "right," indicating strength of preference for each activity; 2 checks are to be used if the individual "would never try to use the other hand unless absolutely forced to" for the given function. As some activities require the use of both hands, the directions specify which component reflects hand preference (e.g., in striking a match, the hand that holds the match). A laterality quotient (LQ = R - L/R + L ? 100) can be calculated where a score of 100 reflects complete dextrality, and a score of -100 is obtained by complete sinistrals" (Caplan & Mendoza, 2011).
This task should be included in every neuroimaging study. It is essential to aid in the interpretation of neuroimaging results.
