| Abstract: | The psychometric properties of the Icelandic version of the World Health Organization five wellbeing index (WHO‐5) were evaluated using two samples, a randomly selected sample (N = 3,896) from the Icelandic National Registry and a convenience sample of primary care patients (N = 126). The factor structure of the scale was tested with confirmatory factor analysis (CFA). The correlation between the WHO‐5 and other measures of depression and anxiety were calculated to assess the scale's convergent and divergent validity. The discriminant validity of the WHO‐5 was explored with a receiver operating analysis compared to the Mini International Neuropsychiatric Interview. The CFA indicated that the factor structure of the WHO‐5 was one‐dimensional and factorial invariant between groups. The internal reliability of the WHO‐5 was adequate and the convergent, divergent and discriminant validity of the WHO‐5 was supported. It is concluded that the psychometric properties of the Icelandic version of the WHO‐5 are satisfactory. |
