摘要

目的将简明膳食自评工具（SDSAT）应用在食管癌术后患者中，评价其信度和效度。方法本研究通过3个研究分别测量SDSAT的评定者间信度、重测信度和预测效度。研究A选择食管癌术前患者60例，由2位研究者分别进行SDSAT的测量，评价评定者间信度。研究B最终纳入食管癌术后1个月患者30例进行SDSAT的测量，间隔2周复测1次，比较2次结果，评价重测信度。研究C最终共纳入171例食管癌患者通过测量术前、术后1个月和术后3个月3个时间点测量，评价SDSAT对前白蛋白含量的预测程度。结果评定者间信度是0.854（P<0.01）。重测信度是0.782（P<0.01）。通过广义预测方程发现SDSAT对患者的前白蛋白含量预测效果好（P<0.01）。结论SDSAT信效度好，适合应用于评价食管癌术后患者的饮食状况。

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.
