Objective To explore the intervention effect of Gibbs Reflective Cycle on self-reflection and insight ability and learning access of nursing postgraduates in peritoneal dialysis center.Methods A total of 64 nursing postgraduate students who performed cli-nical practice were selected by convenience sampling method, 33 cases were divided into control group and 31 cases were divided into experimental group according to admission time.The control group adopted the traditional teaching method, and the experimental group adopted the Gibbs Reflective Cycle for clinical practice teaching for 4 weeks.The postgraduate students completed the reflection diary according to the requirements of the Gibbs Reflective Cycle, reported and shared the reflection results and applied them to clinical practice.The self-reflection and insight ability and learning access were compared between the two groups before and after the intervention.Results After intervention, the score of self-reflection and insight ability of the control group was (67.82±2.80), and that of the experimental group was (85.29±2.39); After intervention, the score of learning access of control group was (92.36±2.53), and that of the experimental group was (98.48±4.36), the difference between the two groups was significant (both P＜0.05).Conclusion Gibbs Reflective Cycle can improve the self-reflection and insight ability and learning access of nursing postgraduates in peritoneal dialysis center.
