title: Reliability and validity of the Jefferson scale of attitudes toward physician-nurse collaboration for nurse practitioners.
abstract: BACKGROUND
  The Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (JSATPNC) has been used to measure attitudes regarding nurse-physician collaboration. However, psychometric evaluation is lacking for the nurse practitioner (NP) population.
  
  
  OBJECTIVE
  This study details a confirmatory approach in testing the factor analytic structure of the JSATPNC against previously reported structures.
  
  
  METHODS
  A Web survey invited 4,673 licensed NPs where 915 responded. Confirmatory factor analysis (CFA) was performed to assess factorial validity.
  
  
  RESULTS
  A previously proposed 3-factor model based had significantly better fit compared to a 1-factor structure (delta chi2 = 165.3, delta df = 3, p < .0001). Cronbach's alpha for the 3 subscales were 0.61, 0.62, and 0.54. Reliability with all 15 items was .72.
  
  
  CONCLUSIONS
  Three collaboration subscales could have use in measuring attitudes toward physician-NP collaboration.
