title: The Nurses Self-Concept Instrument (NSCI): assessment of psychometric properties for Australian domestic and international student nurses.
abstract: BACKGROUND
  Professional self-concept is a critical driver of job satisfaction. In Australia, as international nursing enrolments rise, nursing is increasingly characterised by a professional body of international nurses who may differ from domestic Australian nurses in their nursing self-concept. At present, no psychometrically sound instrument for assessing nursing self-concept for Australian domestic and international nursing students is available.
  
  
  OBJECTIVE
  The purpose of this study was to: (1) develop an instrument (the Nurses' Self-Concept Instrument (NSCI)) to measure the professional self-concept of domestic and international nursing students in Australia, and (2) test the psychometric properties of this newly developed instrument.
  
  
  METHODS
  A literature review was conducted to generate the initial dimension and item pools to measure nurses' professional self-concept (NSCI). Two stakeholders examined the content and face validity of dimensions and items. Analysis was performed on data collected from 253 undergraduate nursing students in a large public university in Sydney, Australia, and consisted of domestic (n=218) and international (n=35) nursing students. Internal reliability was assessed using Cronbach's Alpha. Confirmatory factor analysis (CFA) was used to assess the construct validity of the NSCI.
  
  
  RESULTS
  The resulting NSCI consisted of 14 items across four self-concept domains: care, leadership, staff relations, and knowledge. The CFA supported the hypothesised factor structure of the self-concept model. All reliabilities were acceptable for both domestic and international students (ranging from r=.78 to .93).
  
  
  CONCLUSIONS
  The NSCI was shown to be a valid and reliable tool for assessing Australian domestic and international student nurses' professional self-concept. This instrument may also enable those responsible for recruitment of students into nursing courses to assess students' professional self-concept and implement appropriate strategies to foster the growth of lifelong career development.
