Methods Convenience sampling method was used and totally 495 caregivers of premature infants of Army General Hospi-tal affiliated BaYi Children hospital from April to August 2016 has been investigated .After we had preliminary content of the question-naire, two-round Delphi consultations were used to identify the draft of the scale , and the reliability and validity were tested . Results Totally 419 valid questionnaires from 495.Questionnaires effective recovery was 84.65%.Critical ratio for each entry was 9.355-23.179 ( P<0.05) , which suggested that entries had good distinction .Coeffi-cient of correlation between scale items and total score was 0.500-0.775(P<0.05), whichindicated highly homogeneity between entries and table.By exploratory factor analysis , 5 entries were removed and 77 entries remained .The final scale of caregivers′cognitive level on continuous nursing care for premature infants included 4 indicators in level one , 15 indicators in level two and 77 indicators in level three .The Cronbach′s alpha was 0.985 for overall questionnaire and 0.848-0.939 for each dimension .The split-half reliability was 0.895 for overall questionnaire and 0.814-0.939 for each dimension .The content validity index was 0.963.The cumulative contribution rate of each dimension was 64.645%-83.236%.
