Results: According to psychometric factors including eating behaviors, fluid intake, vitamin and mineral supplement intake, fruits, vegetables, whole grain and protein intake, physical activity and dumping syndrome management, 6 factors could explain 61.5% of BSSQ. Total score of correlation matrix BSSQ with GAS and SAS were 0.36 and 0.70. For
reliability, the Cronbach’s alpha coefficient was found 0.90 and Guttmann split-half coefficient was 0.78.
