Cross-cultural adaptation and validation to Brazil of the Obesity-related Problems Scale

Abstract

Objective To validate a reliable version of the Obesity-related Problems Scale in Portuguese to use it in Brazil.Methods The Obesity-related Problems Scale was translated and transculturally adapted. Later it was simultaneously self-applied with a 12-item version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), to 50 obese patients and 50 non-obese individuals, and applied again to half of them after 14 days.Results The Obesity-related Problems scale was able to differentiate obese from non-obese individuals with higher accuracy than WHODAS 2.0, correlating with this scale and with body mass index. The factor analysis determined a two-dimensional structure, which was confirmed with χ2/df=1.81, SRMR=0.05, and CFI=0.97. The general a coefficient was 0.90 and the inter-item intra-class correlation, in the reapplication, ranged from 0.75 to 0.87.Conclusion The scale proved to be valid and reliable for use in the Brazilian population, without the need to exclude items.

Measuring health and disability of Ukrainian cadets – translation and cross-cultural adaptation of the WHODAS 2.0

“…Translation and adaptation of WHODAS 2.0 were carried out in different languages [5][6][7][8][9][10], sufficient attention is paid to the study of psychometric properties on the example of patients with different nosologies [11][12][13][14][15][16][17], as well as for different groups in high-income countries [3,18], middle-income countries [18], and developing countries [9,20].…”
