Health related quality of life measures in Arabic speaking populations: A systematic review on cross-cultural adaptation and measurement properties

This systematic review was conducted to identify generic health related quality of life (HRQL) measures translated into Arabic,
and evaluate their cross-cultural adaptation and measurement properties.

Six databases were searched, relevant journals were hand searched, and reference lists of included studies were reviewed.
Previously established criteria were used to evaluate the cross-cultural adaptation of the identified instruments and their
measurement properties.

Twenty studies that reported the Arabic translations and adaptations of HRQL measures and/or their measurement properties
were included in this review. The identified instruments were SF-36, RAND-36, WHOQOL-Bref, COOP/WONCA charts, EQ-5D, and QLI.
Cross-cultural adaptations of all measures were of moderate to good quality, and evaluation of measurement properties was
limited due to insufficiency of evidence. Based on cross-cultural adaptation evaluation, each instrument is more applicable
to the population for whom it was adapted, and to other Arabic populations of similar culture and language specific idioms.

This review facilitates the selection among existing Arabic versions of generic HRQL for use in particular Arabic countries.
However, each of the translated versions requires further investigation of measurement properties before more concrete recommendations
could be made.
