Abstract 541P
Background
The Functional Assessment of Cancer Therapy-General (FACT-G) scale is widely used to measure health-related quality of life (HRQOL) in patients with cancer. In Mongolia, there is no valid or reliable instrument for measuring HRQOL in patients with cancer. This study aimed to empirically validate the FACT-G scale in patients with cancer in Mongolia.
Methods
In this methodological study, the Mongolian version of the FACT-G was validated in 303 cancer patients recruited from four hospitals in Ulaanbaatar, Mongolia. Data were analyzed using exploratory factor analysis to determine the factor structure. Convergent validity was assessed by calculating the correlation between the FACT-G and the Functional assessment instrument of the COOP/WONCA charts. The internal consistency of the total scale and its subscales was determined using Cronbach’s alpha.
Results
A 4-factor, 20-item model demonstrated a satisfactory fit with significant factor loadings. The factor structure of the Mongolian version of the FACT-G was similar to that of the original version, including the physical, social/family, emotional, and functional well-being subscales, and these four factors explained 65.5% of the variance. There was a significant correlation between the FACT-G and the COOP/WONCA charts (r=.69, p<.001). Cronbach’s alpha for the total scale was .93, and that for the subscales ranged from .72 to 89.
Conclusions
A 4-factor, 20-item model demonstrated a satisfactory fit with significant factor loadings. The factor structure of the Mongolian version of the FACT-G was similar to that of the original version, including the physical, social/family, emotional, and functional well-being subscales, and these four factors explained 65.5% of the variance. There was a significant correlation between the FACT-G and the COOP/WONCA charts (r=.69, p<.001). Cronbach’s alpha for the total scale was .93, and that for the subscales ranged from .72 to 89.
