Development and Validation of the Brief Fatigue InventoryTaiwan

Development and Validation of the Brief Fatigue Inventory-Taiwan Form and M. D. Anderson Symptom Inventory-Taiwan Form n n 英文摘要 Fatigue is the most distressing, prevalent, and ignorant common symptoms in cancer patients. Cancer symptom distress is subjective sense and experience of cancer patients, that seriously interfere with usual functioning and affect quality of life. It requires a simple, available, reliable, sensitive and self-reported instrument, to assess accurate severity levels of fatigue and interference with usual functioning of cancer patients. The purposes of this study was to (1) Development and Validation of the Brief Fatigue Inventory-Taiwan Form and M. D. Anderson Symptom Inventory-Taiwan Form. (2) Explore the severity levels of fatigue, cancer symptom distress, and interference with usual functioning of cancer patients, and correlation between them. A cross-sectional descriptive correlational design was adopt for the study and the structured questionnaire interview was used. Two hundred eligible subjects were recruited by convenience sampling from the oncology inpatients and outpatients in Southern Taiwan. The instruments included BFI-Taiwan Form, MDASI-Taiwan Form, Short Form -POMS, SF-36 -Taiwan Form, and KPS. The validation were establishing reliability by internal consistency ( Cronbach’s α) and test-retest reliability, and validity by construct, discriminant and criterion validity. The sensitivity was presented by comparing the repeated measure scores of received chemotherapy patients. The study results revealed that fatigue and interference intensity of the BFI-Taiwan Form Cronbach’s αwere. 89 and. 91, testretest reliability r were. 80 and. 97. Symptom distress and interference intensity of the MDASI-Taiwan Form Cronbach’s αwere. 85 and. 93, test-retest reliability r were. 97 and. 96. Both instruments have good construct, discriminant criterion validity, and sensitivity. Most of the cancer patients experienced moderate to severe severity levels of fatigue, symptom distress and interference. Cancer-related fatigue and symptom distress were interfere with usual functioning of cancer patients. Severity levels of fatigue and symptom distress were high, the levels of interference were higher. BFI-Taiwan Form and MDASI-Taiwan Form provide rapidly and accurate assessment of the severity levels of fatigue, symptom distress and interference with usual functioning in cancer patients to professionals. Namely provides proper nursing intervention and improve the quality of life in cancer patients.
