Cross-cultural adaptation and validation of Work Productivity and Activity Impairment questionnaires for caregivers of patients with pediatric inflammatory bowel disease in Spain. A multicenter study.

Introduction. The WPAI-UC/CD-Caregiver questionnaires assess the impact of ulcerative colitis (UC) or Crohn's disease (CD) on parents'/caregivers' work life and daily activities. Our objective was to adapt and validate these questionnaires in the Spanish population. Methods. A translation and back-translation were done. The document was assessed by an expert committee and a pilot group of families of patients with pediatric inflammatory bowel disease (p-IBD). For validation, the parents/caregivers of patients with p-IBD (10-18 years old) were recruited. The expert committee and the pilot group conducted a subjective assessment of the format and time necessary to complete the questionnaires. Cronbach's alpha coefficient was estimated and a factor analysis with varimax rotation was done. Kaiser- Meyer-Olkin (KMO) coefficients and Bartlett's sphericity test were estimated to test the adequacy of the factor analysis. Results. A total of 370 patients (median age: 14.1 years) and 263 parents/caregivers of patients with UC or unclassified IBD and 261 parents/caregivers of patients with CD were included. The KMO coefficients (0.6947 and 0.7179) and Bartlett's sphericity test (p < 0.001) confirmed the adequacy of the factor analysis. The 6 items targeted the same domain. The factor model accounted for 99.99% and 94.68% of variance, and Cronbach's alpha coefficients (0.6581 and 0.6968) showed an adequate consistency. The format and the median time of 2 minutes to complete the questionnaires were considered optimal. Conclusions. The versions of the WPAI-Caregiver questionnaires validated in the Spanish population may be used in families whose children have IBD.

Translation, cross-cultural adaptation and validation of the Chinese version of the IBD-Control questionnaire: A patient-reported outcome measure in inflammatory bowel disease.

A demand exists for user-friendly patient-reported outcome measures for patients with inflammatory bowel disease (IBD). The IBD-Control Questionnaire has been recently developed to assess overall disease control from the patient's view but has not been available in China. Translation and cultural adaption of the IBD-Control into Chinese was conducted through four steps (forward translation, backward translation, expert panel, and pilot testing). Afterwards, a prospective validation study was conducted from February 2022 to February 2023. The translated IBD-Control, Short Health Scale, EQ-5D-5L, and disease activity measurements using either the Physician Global Assessment and Simple Clinical Colitis Activity Index or the Crohn's Disease Activity Index were used. Acceptability, test-retest reliability, internal consistency, content validity, convergent validity, structural validity, discriminant ability, and receiver operating characteristic curves were analyzed. Questionnaires were completed by 150 participants with IBD (31 with Crohn's disease [CD] and 119 with ulcerative colitis [UC]). The Cronbach's alpha coefficient was 0.823 for the IBD-Control-8 scale. The correlations between individual item and total score varied from 0.485 to 0.892 among CD patients and from 0.588 to 0.712 among UC patients. The S-CVI/Ave was 0.98. Convergent validity analyses exhibited moderate to strong correlations between other measurements and IBD-Control-8-subscore (0.555-0.675) or IBD-Control VAS (0.503-0.671). Test-retest analysis showed that the mean scores were 75.23±17.33 versus 72.10±14.99 (r = 0.894, p<0.01) for VAS scores and 12.75±3.49versus 12.80±3.29 for IBD-Control-8 subscore (r = 0.963, p<0.01), respectively. The IBD-Control-8-subscore and IBD-Control-VAS exhibited significant discriminative capability among the PGA categories (ANOVA, p < .001). The ROC analysis revealed an optimal cut-off point for the IBD-Control-8 subscore of 14 points (sensitivity: 70.9%, specificity 83.5%), versus a cut-off of 70 on the IBD-Control VAS score (sensitivity: 84.4%, specificity 69.3%). The Chinese IBD-Control proves to be a disease-specific, reliable, and valid tool for revealing overall disease control from the patient's viewpoint. Both healthcare professionals and patients may find it to be a useful patient-reported outcome measurement for triaging IBD patients in China or complementing routine care.
