Abstract
Background: Cross-cultural adaptation of standardized outcome measures between different languages is a common procedure that allows healthcare professionals around the world to utilize such measures in their own languages. The purpose of this study was to investigate the accuracy of translating and cross-culturally adapting the Adolescent/Adult Sensory Profile from English to Arabic and to assess the psychometric properties of the Arabic version. Methods: A backward-forward translation process was used to translate the measure. Eighty-seven bilingual participants completed an English and an Arabic translated version of the measure. Results: The percent agreement for each of the Arabic and English items ranges from 0.77 to 0.98. The kappa values range from 0.79 to 0.84. Test-re-test reliability of the Arabic version was tested on 35 participants. The percent agreement between the first and the second assessment using the Arabic version of the Adolescent/Adult Sensory Profile ranges from 0.80 to 0.96. The kappa values range from 0.82 to 0.88. Internal consistency for the Arabic version was 0.84 and 0.82 for the English version. Construct validity of the Arabic version (n = 560) was tested using factor analysis. Four factors were rotated using a Varimax rotation procedure. The factors' classification and the items' distribution related to these factors were very similar to the English version of the Adolescent/Adult Sensory Profile. Only 9 items of the 60 items (15%) had different distribution than the original version. Conclusion: The Arabic version of the Adolescent/Adult Sensory profile has very good psychometric properties and can be utilized with confidence with Arabic-speaking individuals.
