Aim:
To develop an instrument to investigate knowledge and predictive factors of needlestick and sharps injuries (NSIs) in nursing students during clinical placements.
Design:
Instrument development and cross-sectional study for psychometric testing.
Methods:
A self-administered instrument including demographic data, injury epidemiology and predictive factors of NSIs was developed between October 2018-January 2019. Content validity was assessed by a panel of experts. The instrument's factor structure and discriminant validity were explored using principal components analysis. The STROBE guidelines were followed.
Results:
Evidence of content validity was found (S-CVI 0.75; I-CVI 0.50-1.00). A three-factor structure was shown by exploratory factor analysis. Of the 238 participants, 39% had been injured at least once, of which 67.3% in the second year. Higher perceptions of "personal exposure" (4.06, SD 3.78) were reported by third-year students. Higher scores for "perceived benefits" of preventive behaviours (13.6, SD 1.46) were reported by second-year students.
