title: The novice objective structured clinical evaluation tool: psychometric testing.
abstract: OBJECTIVE
  This paper is a report of a study of the psychometric properties of the Novice Objective Structured Clinical Evaluation Tool.
  
  
  BACKGROUND
  A collaborative undergraduate nursing programme is currently using an objective structured clinical evaluation at the conclusion of the first nursing clinical course to determine student competence as a component of quality and safety education. However, the reliability and validity of the assessment tool has not been established.
  
  
  METHODS
  Psychometric testing was conducted with a convenience sample of 565 nursing students. Data were collected during three consecutive years from 2002 to 2004. Exploratory factor analysis and reliability testing were conducted on this 25-item tool.
  
  
  RESULTS
  Principal axis factoring method identified two factors through the orthogonal, oblimin and promax rotations: Factor 1 Safety and Factor 2, Anticipation. Spearman-Brown's result for Factor 1 was 0·93 and for Factor 2 was 0·77. Cronbach's alpha was.94 for Factor 1 and 0·71 for Factor 2.
  
  
  CONCLUSIONS
  The tool was found to have adequate construct validity and reliability. Its stability should be tested by conducting test-retest analysis. Equivalency dimensions of reliability should be evaluated by looking at interrater reliability. This tool shows merit for assessing elements of quality and safety education.
