Abstract Objective This study aimed to evaluate the reliability and validity of the simple diet self-assessment tool (SDSAT) among esophageal cancer patients after operation. Methods Three studies were conducted to measure the interrater reliability, test-retest reliability and predictive validity separately. Sixty patients were involved in study A prior to operation to be measured by 2 researchers with SDSAT separately in order to get the interrater reliability of SDSAT. Thirty patients were involved in study B 1month after operation to be measured with SDSAT. Two weeks later, they were be measured again to get the test-retest reliability. The predictive validity was established by exploring the impact of the score of SDSAT on prealbumin among 171 esophageal cancer patients in study C which was a longitudinal observational study measured 3 points including before operation, 1month after operation and 3months after operation. Results The interrater reliability of SDSAT was 0.854(P<0.01). Test-retest reliability was 0.782(P<0.01). Generalized estimating equation(GEE) showed that the score of SDSAT had a significant impact on prealbumin(P<0.01), which demonstrated good predictive validity. Conclusion The SDSAT demonstrated favorable reliability and validity. It is appropriate for estimation of dietary intake among esophageal cancer patients.
