Objective  To evaluate the application effects of interdisciplinary educational model in the cultivation of research innovation ability of nursing graduate students.

Methods  The nursing graduate students from grade 2020 to grade 2022 in Bengbu Medical University were selected as study subjects.The interdisciplinary education model(voluntary principle) was adopted in the intervention group, while the traditional education model was adopted in the control group.The cluster sampling was used in the intervention group, and the control group was matched by 1∶1 according to the grade, degree type, gender and research direction.After the intervention, the scientific research consciousness and scientific research innovation ability were compared between two groups.

Results  The total score of research consciousness in the intervention group was significantly higher than that in the control group(P < 0.01), and there was not statistical significance in the dimension scores of "awareness to ask questions" and "awareness to doubt" between two groups(P>0.05).The scores of "finding problem consciousness", "demonstrating problem value consciousness", "exploring problem consciousness" and "innovation consciousness" in the intervention group were higher than those in the control group(P < 0.01).The total score of research innovation ability and its three dimensions("thinking innovation", "method innovation" and "application innovation") in the intervention group were better than those in the control group(P < 0.05 to P < 0.01), and the score of research innovation achievements output in the intervention group was also higher than that in the control group(P < 0.05).

Conclusions  The interdisciplinary education model can significantly improve the research consciousness and research innovation ability of nursing postgraduates.
