title: Psychometric evaluation of the McCloskey/Mueller Satisfaction Scale.
abstract: OBJECTIVE
  The aim of the study was to evaluate and refine the eight-factor structure of the 31 item McCloskey/Mueller Satisfaction Scale, which is one of the most widely used scales for measuring job satisfaction among nurses. However, this scale was developed in 1990 for the American nursing context and its psychometric validity and utility for use with non-American nurse populations have been questioned by various researchers.
  
  
  BACKGROUND
  The eight-factor, 31-item McCloskey/Mueller Satisfaction Scale is one of the most widely used scales for measuring job satisfaction among nurses. However, this scale was developed in 1990 for the American nursing context, and its psychometric validity and utility for use with non-American nurse populations have been questioned by various researchers.
  
  
  METHODS
  Data from a sample of 1007 Canadian nurses who were working in hospital and community settings were analyzed by using an exploratory factor analysis with varimax rotation.
  
  
  RESULTS
  The original factor structure of the McCloskey/Mueller Satisfaction Scale was unable to be replicated. The best-fitting model that was obtained was a five-factor model with 25 items. The Cronbach's alphas for the new McCloskey/Mueller Satisfaction Scale subscales ranged from 0.71 to 0.87, which indicated stronger internal consistency than the original subscales (α = 0.52-0.84).
  
  
  CONCLUSIONS
  The reliability and structural validity of the revised 25 item instrument suggest that it is a potentially sound tool for measuring nurses' job satisfaction. As a result of its sound dimensionality, it could be particularly useful when investigating individual and work factors that impact nurse job satisfaction or when evaluating the outcomes of organizational interventions that are aimed at increasing job satisfaction.
