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).Significance of results: Further testing, especially with regard to the dimensionality of the instrument, is recommended.
