Development of the quick-FAAM: A preliminary shortened version of the foot and ankle ability measure for chronic ankle instability

The study objective was to develop a shortened version of the Foot and Ankle Ability Measure (FAAM) for individuals with chronic ankle instability (CAI). Forty individuals with CAI completed the FAAM Activities of Daily Living and Sport subscales and the Short Form-12. Analyses were completed for item reduction followed by dimensionality, coverage redundancy, and internal consistency of a reduced-item instrument. Validity was examined through correlations with the original FAAM and Short Form-12. A 12-item FAAM was created which demonstrated strong internal consistency and convergent/divergent validity. The Quick-FAAM may provide an alternative patient-reported outcome for CAI which requires less administration time.
