Determinants of Nurses' Safety Incident Reporting: An Extended Theory of Planned Behavior Analysis

Patient safety incident reporting is essential for maintaining health care quality, yet nurses often underreport these issues due to psychological and organizational barriers. Using an extended Theory of Planned Behavior model, 211 nurses at a Seoul hospital were surveyed to assess factors affecting nurses' safety incident reporting. Multiple regression and PROCESS Model 4 revealed that perceived barriers markedly affect reporting behavior, while intention acts as a mediator between attitude or organizational silence and action. No direct effects or moderating barriers were observed; the model explained 16% of the variance. Interventions should foster positive attitudes, reduce organizational silence, and lower perceived barriers.
