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.
