Purpose: To develop a “Self-Evaluation Scale of Medical Accident Prevention Behaviors for Head Nurses” with the aim of ensuring patient safety.
Methods: The items of the scale were generated based on the result of a qualitative study. A national survey was conducted using a 29-item scale reconstructed by a panel of experts and a pilot study. The reliability and validity of the scale were verified by statistical methods using the collected data.
Results: A total of 1,154 questionnaires were distributed, 672 (58.2%) questionnaires were returned, and 580 valid data sets were analyzed.
The results of confirmation of the score distribution of the scale showed that there were no question items with a notable response concentrated on specific options. The item-total correlation coefficients ranged from .39 to .64. Cronbach’s alpha of the scale was .91. The hypotheses which were used to evaluate construct validity by known-groups method were supported. The test-retest reliability was .85. The results of principal component analysis showed a loading of .37 or more for the first component. The contribution rate was 28.3%.
Conclusion: The results support the fact that this 29-item scale has adequate reliability and validity.
