BACKGROUND: Quality of life (QOL) is a universally accepted concept for measuring the impact of different aspects of life on general well-being. Adaptation of existing QOL instruments to local cultures has been identified as a better strategy than development of new ones. AIMS: To translate and adapt the Paediatric Quality of Life Inventory™ Version 4.0 Generic Core Scales (PedsQL™) to the Yoruba language and culture and to test the psychometric properties of the adapted instrument among adolescents. METHODS: Psychometric properties including internal consistency reliability, construct and factorial validity of the Yoruba version of PedsQL™ were evaluated using standard procedures. RESULTS: The self report and proxy scales of the Yoruba PedsQL™ were developed with good cultural relevance and semantic/conceptual equivalence. Results from 527 adolescents revealed a Cronbach's coefficient which exceeded 0.7 for internal consistency reliability for all scores. The healthy subjects reported higher PedsQL™ scores than those with mental health and physical problems, which confirmed construct validity. Confirmatory factor analysis revealed a good model fit for the Psychosocial Health score, but not for the other measures. CONCLUSIONS: The Yoruba PedsQL™ is culturally appropriate and with good internal consistency, reliability and construct validity. More work is needed regarding its factorial validity.
