Abstract

Objectives: Study of well-being of older adults, a rapidly growing demographic group in sub-Saharan Africa, depends on well-validated tools like the WHOQOL-OLD. This scale has been tested on different populations with reasonable validity results but has limited application in Africa. The specific goal of this paper was to examine the factor structure of the WHOQOL-OLD translated into three Ghanaian languages: Ga, Akan, and Kasem. We also tested group invariance for sex and for type of community (distinguished by ethnicity/language). Methods: We interviewed 353 older adults aged 60 years and above, selected from three ethnically and linguistically different communities. Using a cross-sectional design, we used purpose and convenience methods to select participants in three geographically and ethnically distinct communities. Each community was made up of selected rural, peri-urban, and urban communities in Ghana. The questionnaire was translated into three languages and administered to each respondent. Results: The results showed moderate to high internal consistency coefficient and factorial validity for the scale. Using confirmatory factor analysis, we found that the results supported a multidimensional structure of the WHOQOL-OLD and that it did not differ for males and females, neither did it differ for different ethnic/linguistic groups. Conclusions: We conclude that the translated versions of the measure are adequate tools for evaluation of quality of life of older adults among the respective ethnic groups studied in Ghana. These results will also enable comparison of quality of life between older adults in Ghana and in other cultures.
