A psychometric evaluation of the Functional assessment of cancer therapy —kidney symptom index (FKSI-19) among renal cell carcinoma patients suggesting an alternative two-factor structure

ConclusionThe present study is the first to use psychometric methods for examining the factor structure of the FKSI-19 instrument. The hypothesized four-factor structure of FKSI-19 provided a barely acceptable model fit. The two-factor FKSI-14 structure may be used as an alternative or complement to the four-factor structure when interpreting the FKSI-19 instrument.
