Interpretability
- Higher scores indicate greater frequency of doing IADL.
- The raw scores of the 13-item FAI can be transformed to interval scores thereby enabling clinicians and researchers to quantify and monitor IADL function in SCI patients.
- No cut-points or normative data for the SCI population have been established
- Published data for the SCI population is available for comparison (see the Interpretability section of the Study Details sheet)

Reliability
Rasch analysis reliability coefficient was reported to be 0.78.
(Hsieh et al. 2007)
Validity
The Frenchay Activities Index was validated as a unidimensional construct through revision of the scale after Rasch analysis.
(Hsieh et al. 2007)
Responsiveness
No values were reported for the responsiveness of the FAI for the SCI population.
Floor/Ceiling Effect
The FAI exhibited a slight floor effect (9.9% of participants scored the lowest possible score) and no ceiling effect.
(Hsieh et al. 2007)
