Adaptation of the adult Functional Mobility Assessment (FMA) into a FMA-Family Centred (FMA-FC) paediatric version.

Aim: The aims of this study were to adapt an adult wheeled mobility outcome measure, the Functional Mobility Assessment, for use with children (FMA-Family Centred) and establish the new measure's content validity, test-retest reliability, and internal consistency.

Background: Although several tools exist to measure a child's ability to operate and move a wheeled mobility device, none focus on the ability of the wheeled mobility device to support children and their families as they perform daily activities.

Methods: After adapting the FMA items with examples relevant to children aged 3-21, parent/caregiver and therapist stakeholder groups recommended adaptations relevant for families with children who cannot respond for themselves.

Results: Six of the initial FMA items were retained with child-appropriate examples, and 4 new items were developed.

Conclusion: The content validity of the FMA-Family Centred was strongly supported, and internal consistency and test-retest reliability met accepted psychometric standards.
