title: Stages of Change--continuous measure (URICA-E2): psychometrics of a Norwegian version.
abstract: OBJECTIVE
  This paper is a report of research to translate the English version of the Stages of Change continuous measure questionnaire (URICA-E2) into Norwegian and to test the validity of the questionnaire and its usefulness in predicting behavioural change.
  
  
  BACKGROUND
  While the psychometric properties of the Stages of Change categorical measure have been tested extensively, evaluation of the psychometric properties of the continuous questionnaire has not been described elsewhere in the literature.
  
  
  METHODS
  Cross-sectional data were collected with a convenience sample of 198 undergraduate nursing students in 2005 and 2006. The English version of URICA-E2 was translated into Norwegian according to standardized procedures.
  
  
  RESULTS
  Principal components analysis clearly confirmed five of the dimensions of readiness to change (Precontemplation Non-Believers, Precontemplation Believers, Contemplation, Preparation and Maintenance), while the sixth dimension, Action, showed the lowest Eigenvalue (0.93). Findings from the cluster analysis indicate distinct profiles among the respondents in terms of readiness to change their exercise behaviour.
  
  
  CONCLUSIONS
  The URICA-E2 was for the most part replicated from Reed's original work. The result of the cluster analysis of the items associated with the factor 'Action' suggests that these do not adequately measure the factor.
