Development of the Chedoke Arm and Hand Activity Inventory: theoretical constructs, item generation, and selection

The Chedoke Arm and Hand Activity Inventory (CAHAI) was developed to address the need for a valid, clinically relevant, responsive functional assessment of the recovering paretic upper limb. The purpose of this article is to describe the development of the measure including its theoretical constructs, item generation, and item selection. From the literature, survivors of stroke, and their caregivers, 751 items were generated. Using factor analyses stem leaf plots, clinical judgment, and pilot testing on individuals with stroke, the list was reduced to 13 bilateral, real-life items. Research continues to provide evidence of the CAHAI's test-retest and interrater reliability as well as construct, concurrent, and longitudinal validity.
