Abstract

This study aimed to develop a valid and reliable measurement instrument for determining the self-efficacy perceptions of nurses concerning safe medication practices. The study was conducted at the hospital of a state university in Istanbul, Turkey, between August and December 2016. The sample consisted of 278 nurses. The exploratory factor analysis indicated the scale had a single-factor structure that explained 47.92% of the total variance. The remaining 76 items had factor loads ranging from .50 to .87. The item-total correlations varied between .49 and .86, and Cronbach's alpha coefficient for the scale was .98. The results of the analysis show the items constituting the scale have validity and reliability criteria that can measure the self-efficacy of nurses related to parenteral medication administration.
