Protocol - Hand Dominance - 12 Years and Older

Add to My Toolkit
Description:

The protocol consists of questions to determine which hand the participant uses for a series of activities.

Protocol:

The following protocol is part of a personal interview in which the participant reports on his/her own hand usage. Young Adult and Adult handedness is assessed using an 11-item scale. Please indicate your preferences in the use of hands in the following activities by putting a 1 in the appropriate column (for right only, left only, or both hands) for each item that you use.

Right hand

Left hand

Both hands

1. Write

2. Draw

3. Throw

4. Hold a racquet

5. Clean teeth

6. Hammer

7. Strike a match

8. Use an eraser

9. Deal cards

10. Thread a needle

11. Cut food with a knife

Total

Scoring: The participant indicates use by a "1" in the appropriate column (for right, left, or both) for each item that an adult uses. Add the "1"s in each column to get a total for that column. The sum of all three column totals is the cumulative total. To calculate the score: 100 x (right total - left total)/cumulative total. Handedness is then classified as follows:

Scoring:

Less than -40left-handed
Greater than or equal to -40 and less than 40mixed-handed
Greater than or equal to 40right-handed
Note: The activities listed in the Edinburgh Handedness Inventory method have been modified by the PhenX Anthropometrics Working Group.

Personnel and Training Required

The trained interviewer should be able to administer a questionnaire and be able to probe for information as necessary.

Mode of Administration

Self- or proxy-reported value

Life Stage:

Adolescent, Adult, Senior

Participants:

This measure includes two protocols, each relating to a specific age of the participant. Consistent hand dominance starts to develop between 2 and 3 years of age and is usually completed by 6 years of age. Hand preference that appears before the age of 18 months may signal impaired neurological control of the other hand.

Definition

Dominance is measured to assess the movement, mobility, and flexibility of an individual to determine which side of the body the study subject favors or the strength of hand activity.

Purpose

This measure is used to determine which hand is dominant or more skilled for fine motor tasks than the other. Of the general population, about 90% have right hand dominance, about 10% have left hand dominance, and about 1% are mixed-handed or can use either hand interchangeably to complete a fine motor task (Porac & Coren, 1981). Hand dominance is thought to be influenced by genetics, and loci for relative hand skill have been mapped.
