Abstract

Background and Purpose: It has been shown that nurse confidence predicts peripheral intravenous catheter (PIVC) insertion success. However, intravenous cannulation is a challenging skill for entry to practice students. To date, there is no well-validated measure of nursing student self-confidence in learning and performing PIVC insertion. To address this measurement gap, we created and validated the Nursing Student PIVC Insertion Self-Confidence Scale. Methods: This study employed a descriptive, cross-sectional design. Three cohorts of undergraduate entry-to-practice students at a Canadian university were recruited and assessed during their studies. Two hundred and eighty-one students completed the scale at the first data collection point and 146 at the second point. The structure of the tool was analyzed by exploratory factor analysis to extract factors and confirmatory factor analysis (CFA) was employed for validation. Results: CFA revealed a three-factor scale (PIVC Cannulation Confidence, PIVC Preparation and Securement Confidence, and PIVC Learning Confidence). It has 15 items with satisfactory goodness of fit indices. Conclusions: The Nursing Student PIVC Insertion Self-Confidence Scale is a valid and reliable scale to measure nursing students' confidence in learning about and performing PIVC insertions.
