Psychometric analysis of the Functional Assessment of Cancer Therapy-General (FACT-G) scale in a rural sample
1School of Nursing, University of Vermont, Burlington 05405, USA.
Background:
Quality of life for persons with cancer has been studied extensively in urban populations. The Functional Assessment of Cancer Therapy-General (FACT-G) scale was developed for use in clinical trials. The authors tested the psychometric properties of the FACT-G scale in a sample of rural cancer patients.
Methods:
A systematic replication of the 1993 study by Cella et al., in which FACT-G was developed, was employed to assess the reliability, validity, and factor structure of the scale.
Results:
The reliability and validity of the FACT-G scale for evaluating rural cancer patients was determined to be sufficient for research purposes. The factor structure was the same as that reported by Cella et al.
Conclusions:
The FACT-G scale is appropriate for use in studies of the quality of life of rural cancer patients.
