title: The Norwegian version of the Herth Hope Index (HHI-N): a psychometric study.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the psychometric properties of the Herth Hope Index (HHI) in a representative sample of the Norwegian population.
  
  
  METHODS
  The HHI-N was administered to 4000 people randomly selected from the Norwegian population. 1893 questionnaires were usable, yielding a response rate of 48.5%.
  
  
  RESULTS
  The internal consistency of the HHI-N, estimated by Cronbach's alpha, was 0.81. Factor analysis resulted in a two-factor solution, which explained 38% of the variance. The correlation between hope and overall quality of life was 0.48 (p < 0.001), and between hope and fatigue severity -0.30 (p < 0.001).
  
  
  CONCLUSIONS
  Further testing, especially with regard to the dimensionality of the instrument, is recommended.
