Purpose: This study was done to verify effects of a self-directed feedback practice using smartphone videos on nursing students'basic nursing skills, confidence in performance and learning satisfaction. Methods: In this study an experimental study with a posttestonly control group design was used. Twenty-nine students were assigned to the experimental group and 29 to the controlgroup. Experimental treatment was exchanging feedback on deficiencies through smartphone recorded videos of nursing practiceprocess taken by peers during self-directed practice. Results: Basic nursing skills scores were higher for all items in the experimentalgroup compared to the control group, and differences were statistically significant [“Measuring vital signs” (t= - 2.10, p =.039);“Wearing protective equipment when entering and exiting the quarantine room and the management of waste materials” (t= - 4.74,p qqqlt;.001) “Gavage tube feeding” (t= - 2.70, p =.009)]. Confidence in performance was higher in the experimental group compared tothe control group, but the differences were not statistically significant. However, after the complete practice, there was a statisticallysignificant difference in overall performance confidence (t= - 3.07. p =.003). Learning satisfaction was higher in the experimentalgroup compared to the control group, but the difference was not statistically significant (t= - 1.67, p =.100). Conclusion: Resultsof this study indicate that self-directed feedback practice using smartphone videos can improve basic nursing skills. The significanceis that it can help nursing students gain confidence in their nursing skills for the future through improvement of basic nursing skillsand performance of quality care, thus providing patients with safer care.
