Objective: The objective was to design and validate a tool for assessing nursing students’

process, and the resulting tool (the NURSPeM) was administered to nursing students to examine its
internal consistency, temporal stability, and construct validity, the latter through exploratory factor

two questionnaires: (1) Self-perceptions about safe medication management (27 items) and (2) the
frequency and learning of drug-dose calculation (13 items). The tool’s psychometric properties were

All 13 items in questionnaire 2 were retained. Both questionnaires showed good internal consistency
