Identifying the content of the Lower Extremity Motor Activity Log based on the International Classification of Functioning, Disability and Health.

Purpose: To identify the content and the constructs measured in the Lower Extremity Motor Activity Log (LE-MAL) based on the International Classification of Functioning, Disability and Health (ICF) framework and to determine whether the instrument items fit within the ICF mobility domain.

Methods: Concepts and constructs measured within each scale were linked to the best-matched ICF categories and classified using established linking rules. Two independent researchers determined the initial linkages. A final consensus was reached with the other researchers. The agreement was analysed through the agreement percentage and the kappa coefficient.

Results: The subscales assess performance through information about need or dependency, personal and environmental factors, and appraisal of the items. Thirteen concepts were identified in LE-MAL: two concepts for the Assistance Scale are covered in the environmental factors component; 10 concepts for the Functional Performance Scale where all items are covered in the mobility domain; one concept for the confidence scale is covered in the body functions component.

Conclusions: The general construct of LE-MAL assessed is performance in the ICF mobility domain and provides additional information about the mental function, environmental factors, independence, appraisal, and personal factors. The study highlighted the conceptual connection between the LE-MAL and the ICF framework.
