Construct Validity of the Revised High-Level Mobility Assessment Tool for Children Who Are Developing Typically.

Objective: The aim of this project was to evaluate the construct validity of the high-level mobility assessment tool (HiMAT) for children who are developing typically with no underlying condition that may affect mobility.

Methods: The HiMAT is a revised 8-item measure of high-level mobility. Rasch analysis was used to assess fit to the Rasch model indicating unidimensionality, person separation index local dependency, targeting of items, and differential item functioning.

High-Level Mobility Assessment Tool Normative Values for Children.

Background: Physical therapists need to be able to evaluate high-level gross motor skills of children to determine their capacity to engage in activities such as running, jumping, hopping, and stair climbing. The High-Level Mobility Assessment Tool (HiMAT) has excellent interrater and retest reliability and is less susceptible to a ceiling effect than existing mobility scales in children who are 6 to 17 years old and have traumatic brain injury.

Objective: The purposes of this study were to develop normative HiMAT score ranges for Australian children and to investigate the relationship between children's HiMAT scores and their age, height, weight, and body mass index (BMI).
