Abstract
BACKGROUND AND STUDY AIMS
Celiac disease (CD) management is based on a lifelong gluten-free diet (GFD) that affects the quality of life (QoL) of patients with CD. Specific instruments have been used to evaluate this QoL, such as the CD-Questionnaire (CD-Q). This study aimed to translate, validate, and cross-culturally adapt the CD-Q in an Arabic version and then apply it to evaluate the QoL of Moroccan adult patients with CD.
PATIENTS AND METHODS
The Moroccan version of the CD-Q (M-CD-Q) was administered to 150 patients with CD, and 112 of them completed it. The reproducibility and reliability of the M-CD-Q were studied by the intraclass coefficient (ICC) and Cronbach's α, respectively. Parametric and nonparametric tests, confirmatory factor analysis, and Spearman correlation were used for the statistical analysis performed by SPSS, and the goodness-of-fit test was determined using SPSS AMOS.
RESULTS
No difficulties were found during the translation and cultural adaptation of the CD-Q. Cronbach's α showed good internal consistency. The retest showed excellent reproducibility (ICC > 0.4). The study of the psychometric properties of the M-CD-Q showed good acceptance, zero ceiling effect, and floor effect. The model fit was good [(root mean square error of approximation = 0.075 (<0.08) and χ2 = 509.04, p < 0.001]. The total scores showed a neutral QoL. This QoL was worse in the worries subscale, which is related to gluten-free products. The GFD did not improve the QoL of the examined samples.
CONCLUSION
The M-CD-Q is the first reliable and adapted instrument in an Arab country for the evaluation of QoL in patients with CD. CD negatively influences this QoL, especially items related to gluten-free products.
