The foot function index with verbal rating scales (FFI-5pt): A clinimetric evaluation and comparison with the original FFI.
OBJECTIVE To assess the clinimetric value of the Dutch version of the Foot Function Index ( FFI ) in comparison with the original FFI using verbal rating scales ( FFI-5pt ) rather than visual analog scales ( VAS ) . METHODS A prospect i ve study was performed on 206 patients with nontraumatic forefoot complaints . Scoring , internal consistency , and construct validity of the FFI-5pt were compared with those of the original FFI , which rates all items on VAS . We also studied agreement between the scores at baseline and after one and 8 weeks and the scale scores with regard to sex , age , presence of osteoarthritis , limitation of mobility , bodily pain , and poor physical functioning ( using SF-36 ) . RESULTS Some items were not applicable ; removal of these items left 2 scales ( Pain and Disability ) with high internal consistency ( alpha = 0.88 to 0.94 ) and good agreement between both versions ( intraclass correlation coefficient 0.64 to 0.79 ) . Principal component analysis with varimax rotation using a forced 2 factor model fitted well ( 65 % explained variance ) . Test-retest reliability was high ( ICC 0.70 to 0.83 ) , while the stability over 8 weeks was lower , but still good ( ICC 0.63 to 0.71 ) . Responsiveness to change was low to moderate . However , a small number of patients reported an overall change ( 19 % ) . Scores of patients with limited mobility and poor physical health ( SF-36 ) were higher than those of patients with fewer physical problems , indicating good concurrent validity . CONCLUSION The FFI-5pt is a suitable generic measure . Its clinimetric properties are comparable with those of the original FFI . Its administration and data entry are less time consuming . However , responsiveness has to be more exactly assessed in an intervention study
