Purpose: This study examined the effects of a morphine overdose patient care simulation education program on nursing students’ error reporting intention, disclosure self-efficacy, patient safety attitude, and ethical decision-making confidence. Method: A quasi-experimental one-group pretest–posttest–follow-up design was used with 44 senior nursing students enrolled in a nursing management simulation course. Participants completed a simulation program incorporating error reporting, disclosure, and ethical decision-making. Data were collected at pretest, posttest, and a 4-week follow-up and analyzed using linear mixed models. Results: All outcome variables significantly improved over time. Compared with pretest scores, error reporting intention significantly increased at posttest and follow-up (β=.415, p=.001; β=.401, p<.001). Disclosure self-efficacy also increased at posttest and follow-up (β=.523, p=.002; β=.541, p=.001), as did patient safety attitude (β=.260, p<.001; β=.292, p=.003) and ethical decision making confidence (β=.381, p=.002; β=.505, p<.001). No significant differences were found between posttest and follow-up. Conclusion: The program was associated with improvements in nursing students’ error reporting intention, disclosure self-efficacy, patient safety attitude, and ethical decision-making confidence. These findings suggest that the program may help strengthen nursing students’ competencies in responding to patient safety incidents.
