City of Hope-Quality of Life Questionnaire-Arabic Version: Assessment of Reliability and Validity

Abstract

Abstract BACKGROUND: Arabic is spoken as a native language by more than 400 million people worldwide. However, there is no specific Arabic language instrument to measure stoma-related quality of life. PURPOSE: This study was designed to assess the validity and reliability of the City of Hope-quality of life-Ostomy Questionnaire (COH-QOL-OQ) Arabic version. METHODS: A cross‑sectional design was used. Intra-class correlation coefficients were calculated to measure reliability, and Pearson’s correlations of an item with its own scale and other scales were scored to evaluate convergent and discriminant validity. Content validity was reviewed by a panel of 5 experts. RESULTS: There were 421 participants with colostomy, ileostomy, or urostomy (239 [56.8%] male and 182 [43.2%] female). All COH-QOL-OQ subscales for the Arabic version demonstrated a high level of internal consistency (Cronbach's α = 0.71–0.87). The initial administration of the confirmatory factor analysis model showed inadequate goodness-of-fit indices (χ² /df = 3.902, NFI = .845, CFI = .880, RMSEA = 0.083). However, after removing item 2 in the social dimension, the final administration of the confirmatory factor analysis model showed significant goodness-of-fit indices (χ² /df = 2.663, NFI = .900, CFI = .935, RMSEA = 0.063). CONCLUSION: The findings suggest that the COH-QOL-OQ Arabic version is a valid and reliable tool to measure quality of life among patients with an ostomy in Saudi Arabia.
