Abstract
Objective
To translate the 10-item Identity-Consequence Fatigue Scale and carry out the reliability and validity test and determine the cut-off point.
Methods
The 10-item ICFS was translated into Chinese and adapted to Chinese culture followed the guideline. 74 patients with gastrointestinal tumor were recruited and were investigated by the Chinese version scale. The reliability and validity were tested. The cut-off point is defined by receiver operating characteristic curve and threshold effect analysis.
Results
The Chinese version of ICFS still retained 10 entries and the content validity index was 0.96. Item analysis indicated each item in the critical ratio was significant, and the correlation coefficients to the total scores reached above 0.5. Exploratory factor analysis indicated that Chinese version scale consisted 2 factors which explained 77.337% of total variance, and factor loading was higher than 0.4. Strong correlations were found with cancer-related fatigue. The internal consistency reliability coefficients were 0.928 for total scale, 0.907 and 0.877 for the 2 factors respectively. The criterion validity with cancer-related fatigue is 0.874. The ROC curve showed the Youden index was the largest when the score was 22 according to anxiety and depression. The threshold effect analysis showed the value was 24 according to hand grip. Therefore, the cut-off point of patients after gastrointestinal tumor surgery is 24.
Conclusion
The Chinese version of ICFS-10 has good reliability and validity and can access postoperative fatigue. The cut-off point is 24 and can be used as a warning for the adverse effects on physiological and psychological health.
