BackgroundThis paper describes the development and psychometric properties of the Health and Functioning ICF‐60 (HF‐ICF‐60) measure, based on the World Health Organization (WHO) ‘International Classification of Functioning, Disability and Health: ICF’ (2001). The aims of the present study were to test psychometric properties of the HF‐ICF‐60, developed as a measure that would be responsive to change in functioning through changes in health and nutritional status, as a prospective measure to monitor health and nutritional status of populations and to explore the relationship of the HF‐ICF‐60 with quality of life measures such as the World Health Organization WHOQOL‐BREF quality of life assessment in relation to non‐communicable diseases.MethodsThe HF‐ICF‐60 measure consists of 60 items selected from the ICF by an expert panel, which included 18 items that cover Body Functions, 21 items that cover Activities and Participation, rated on five‐point scales, and 21 items that cover Environmental Factors (seven items cover Individual Environmental Factors and 14 items cover Societal Environmental Factors), rated on nine‐point scales. The HF‐ICF‐60 measure was administered to the Russian nationally representative sample within the Russian National Population Quality of Life, Health and Nutrition Survey, in 2004 (n = 9807) and 2005 (n = 9560), as part of the two waves of the Russian Longitudinal Monitoring Survey (RLMS). The statistical analyses were carried out with the use of both classical and modern psychometric methods, such as factor analysis, and based on Item Response Theory, respectively.ResultsThe HF‐ICF‐60 questionnaire is a new measure derived directly from the ICF and covers the ICF components as follows: Body Functions, Activities and Participation, and Environmental Factors (Individual Environmental Factors and Societal Environmental Factors). The results from the factor analyses (both Exploratory Factor Analyses and Confirmatory Factor Analyses) show good support for the proposed structure together with an overall higher‐order factor for each scale of the measure. The measure has good reliability and validity, and sensitivity to change in the health and nutritional status of respondents over time. Normative values were developed for the Russian adult population.ConclusionsThe HF‐ICF‐60 has shown good psychometric properties in the two waves of the nationally representative RLMS, which provided considerable support to using the HF‐ICF‐60 data as the normative health and functioning values for the Russian population. Similarly, the administration of the WHOQOL‐BREF in the same two waves of the nationally representative RLMS has allowed the normative quality of life values for the Russian population to be obtained. Therefore, the objective assessment of health and functioning of the HF‐ICF‐60 could be mapped onto the subjective evaluation of quality of life of the WHOQOL‐BREF to increase the potential usefulness of the surveys in relation to non‐communicable diseases. © 2014 The Authors.
