Validity and Reliability of Arabic Version of Quality of Life Questionnaire in Patient with Chronic Wound

Background: Chronic wounds are frequent, long-lasting, and impose substantial socioeconomic burdens, significantly affecting patients’ quality of life (QoL). Regular QoL assessment using questionnaires helps guide interventions and optimize wound management. The Arabic version of the QoL questionnaire is a 17-item scale designed to assess QoL in patients with chronic wounds. However, its validity and reliability have not been assessed for Egyptians. Purpose: To assess the validity and reliability of the newly translated Arabic version of the QoL questionnaire among Egyptians with chronic wounds. Methods: The questionnaire was translated into Arabic (forward and backward) and culturally adapted. Ninety-seven patients with chronic wounds were recruited from El-Kasr El-Ainy Hospital, Cairo University's Faculty of Physical Therapy outpatient clinic, and 23 July Hospital in El Marg. Test-retest reliability, internal consistency (Cronbach's alpha), and face and content validity were examined. Results: The Arabic QoL questionnaire demonstrated excellent internal consistency with a Cronbach's alpha of 0.9. Test-retest reliability for all items was excellent, with intraclass correlation coefficients (ICC) ranging from 0.84 to 0.98, and 0.81 for the total score. The questionnaire also showed excellent face validity (clarity index 95.3% and expert clarity proportion 95.9%) and strong content validity (content validity index 98% and expert relevance proportion 97.6%). Conclusion: The Arabic version of the QoL questionnaire is valid and reliable for assessing the quality of life of Egyptians with chronic wounds. It is recommended for use in both clinical practice and scientific research.
