In determining hand preference, observation, forms filled out by people such as which hand they write with, or questionnaires on hand use are used.12-14 Studies have shown that determining the dominant hand of individuals with only one action, such as observation/writing, usually does not reflect the result; hand preference questionnaires are used to reach the correct result.15,16 The most widely used of these questionnaires is the Edinburgh Hand Preference Questionnaire.12 The questions of the questionnaire are suitable for all ages and are easy to understand and apply. It also includes activities that are so general that cultural adaptation is not necessary.
The Edinburgh Hand Preference Inventory was developed by Oldfield in 1971. The purpose of the development of the inventory is to determine the hand that individuals predominantly use.
It is a scale used to determine hand preferences, which questions the hand or hands used in performing 10 different hand activities during daily activities and is used to decide whether a person is left-handed, right-handed or ambidextrous (Edinburgh Handedness Inventory; Oldfield, 1971).
The Edinburgh Handedness Inventory is perhaps the most widely used scale in determining handedness because it provides results on which hand the person uses more than the other hand and at what rate, and it also has an easy-to-apply and understandable answering scheme.
It is an inventory that asks participants which hand they use for activities such as writing, drawing, throwing, using scissors, brushing teeth, using a knife without a fork, using a spoon, using a broom, using matches and opening jar lids. According to the majority of the answers given, it is aimed to determine the dominant (predominant) hand of the person.
