Handfast

Why use the AHA?

The ability profile has been created from information provided by a Rasch measurement analysis which was used to develop and evaluate the test. The Rasch analysis produced information about the level of difficulty for the individual items. This information can be useful to define goals for treatment of hand function appropriate for the child's ability level.

The profile for the individual child shows which of the test items the child perform effectively and those items not yet mastered. Those not yet mastered are considered to be challenging for the child but achievable, making them suitable goals for intervention.

In summary, the AHA provides an ability measure in terms of a sum score. The sum score can be used to describe ability, monitor change over time and evaluate interventions. The AHA also provides a descriptive profile of how the child uses their two hands together. This information can be used to guide intervention.
