Abstract: This study developed and validated the contents of an inventory of global lateral preference (IPLAG) that can be applied as self-assessment which included representing everyday tasks and different dimensions of laterality, such as (a) hand preference, (b) foot preference, (c) trunk preference, (d) eye preference, and (e) ear preference. To validate the IPLAG, it was referred for evaluation of content by professional doctors in the area of Motor Behavior in Brazil. It was analyzed the coherence of the task with the lateral dimension proposed, the understanding of the statement in the proposed task, suggestions for modification in the description of the proposed tasks, also allowing the reviewers to suggest other tasks for the inventory, and other suggestions for the inventory improvement. The analysis of the suggestions from the reviewers was held in a quantitative manner, using absolute and relative frequency of the notes supplied by the evaluators, and qualitatively by a Likert scale established in the instrument provided to reviewers. Evaluators’ analyses pointed to the quality of IPLAG as a feature for assessing global lateral preference. Therefore, the IPLAG may be an interesting feature for research and practical diagnostic applications related to the different manifestations of human laterality.

Key Words: IPLAG, laterality, lateral preference, inventory, motor behavior.
