Objective To construct effect evaluation indicators for diet and nutrition education in adult hematopoietic stem cell transplantation (HSCT) patients,so as to evaluate the effect of education. Methods The "Knowledge-Attitude-Practice" theory was taken as a framework,then related literature in domestic and overseas were searched to develop items of each level in the evaluation indicators,and the final evaluation indicators were determined through 2 rounds of expert (28) consultation and analytical hierarchy process. Results The established evaluation indicators included 3 first-level indicators (knowledge of nutrition management, attitudes toward nutrition management and practices related to nutrition management), 9 second-level indicators,and 25 third-level indicators.Experts′ response rates were 93.55% and 96.55% in the two rounds, experts′ authority coefficients were 0.862 and 0.869,and the Kendall coefficients of concordance were 0.114 and 0.268 respectively (P＜0.05 for both). Conclusion The indicators can be used to evaluate adult HSCT patients′ diet and nutrition knowledge, attitude and practice, understand the effect of education, and guide clinical practice.
