Abstract
INTRODUCTION/OBJECTIVE Central sensitization (CS) is a known contributor to chronic pain in people with knee osteoarthritis (KOA) and is commonly measured by psychophysical testing or patient-reported methods such as the Central Sensitization Inventory (CSI). However, previous studies have shown a weak association between the two. We therefore sought to evaluate the validity of the CSI through Rasch analysis in patients with KOA. METHOD We performed a secondary analysis of a multicenter cohort study with patients with KOA consulting orthopedic surgeons. Rasch analysis was conducted considering person factors of age, sex, BMI, pain intensity, pain catastrophizing, and quantitative sensory test findings using pressure pain thresholds and temporal summation to assess how the CSI fits to the Rasch model (supporting validity). We used RUMM2030 software to model fit estimates, making adjustments as required to achieve model fit (P > 0.05). RESULTS Data from 293 patients were included (58.7% female, mean age 63.6 years, 49.1% obese) Initial evaluation with Rasch modelling indicated misfit. Eleven of 25 items on the CSI displayed disordered thresholds which were rescored by collapsing response categories until the thresholds demonstrated sequential progression. Reanalysis demonstrated persistent model misfit so a subtest was developed to address local dependency of 6 items. Thereafter, model fit was achieved (P = 0.071, indicating not differing from Rasch model) and acceptable unidimensionality (P = 0.068 with 95% CI 0.043-0.093). CONCLUSIONS The CSI was able to be fit to the Rasch model after rescoring while retaining all 25 items. The unidimensionality validates CS as measured by the CSI as a singular construct. Key Points • The Central Sensitization Inventory (CSI) was able to be fit to the Rasch model after rescoring while retaining all 25 items. • The unidimensionality of the CSI validates CS as a singular construct. • Our results suggest rescoring of the CSI for people with KOA, but it should be confirmed and replicated in larger samples prior to clinical use.

Abstract
BACKGROUND AND AIMS Patient-reported outcome measures are increasingly important in daily care and research in inflammatory bowel disease [IBD]. This study provides an overview of the content and content validity of IBD-specific patient-reported outcome measures on three selected constructs. METHODS Databases were searched up to May 2019 for development and/or content validity studies on IBD-specific self-report measures on health-related quality of life, disability, and self-report disease activity in adults. Evidence was synthesised on content validity in three aspects: relevance, comprehensiveness, and comprehensibility following the COnsensus-based Standards for the selection of health Measurement INstruments methodology. Questionnaire items were organised in themes to provide an overview of important aspects of these constructs. RESULTS For 14/44 instruments, 25 content validity studies were identified and 25/44 measures had sufficient content validity, the strongest evidence being of moderate quality, though most evidence is of low or very low quality. The Crohn's Life Impact Questionnaire and IBD questionnaire-32 on quality of life, the IBD-Control on disease activity, and the IBD Disability Index Self-Report and its 8-item version on disability, have the strongest evidence of sufficient relevance, comprehensiveness, and comprehensibility, ranging from moderate to very low quality. A fair number of recurring items themes, possibly important for the selected constructs, was identified. CONCLUSIONS The body of evidence for content validity of IBD-specific health-related quality of life, self-report disease activity, and disability self-report measures is limited. More content validity studies should be performed after reaching consensus on the constructs of interest for IBD, and studies should involve patients.

Abstract
Past research has shown that commonly reported cultural group disparities in health-related indices may be attributable to culturally mediated differences in the interpretation of translated survey questions and response scales. This problem may be exacerbated when administering single-item survey questions, which typically lack the reliability seen in multi-item scales. We adapt the test-retest approach for single-item survey questions that have been translated from English into Spanish and demonstrate how to use this approach as a quick and efficient pilot test before fielding a major survey. Three retest conditions were implemented (English-Spanish, Spanish-English, and English-English) on a convenience sample (n = 109) of Latinos and non-Latinos where translated items were compared against an English-English condition that served as our control. Several items were flagged for investigation using this approach. Discussion centers on the utility of this approach for evaluating the Spanish translation of single-item questions in population-based surveys.

Abstract
OBJECTIVES Ulcerative colitis (UC) can give rise to several restrictions of patients' working and social activities. We aimed to determine the association between disease chronicity and the state of disability in a large population with UC. METHODS We recruited consecutive patients with UC attending the inflammatory bowel disease (IBD) unit of the Azienda Ospedaliera of Padua between July and December 2017. We collected patients' characteristics and clinical information, and all participants completed the IBD questionnaire (IBDQ) for quality of life assessment and the IBD disability index (IBD-DI) questionnaire. Using univariate logistic regression models we assessed whether the patients' characteristics and IBD-related variables were associated with an IBD-DI score ≤3.5. Statistically significant variables in the univariate analyses were then included in a multivariate regression model. Correlations between IBD-DI and all the above mentioned characteristics were investigated using the Spearman's rank correlation coefficient. RESULTS We included 201 patients. A positive correlation was observed between IBD-DI and IBDQ (r = 0.82, P < 0.001). Multivariate regression modelling identified the following as independent factors related to disability: active disease (partial Mayo score ≥2) (odds ratio [OR] 6.54, 95% CI 3.21-13.22), the presence of extraintestinal manifestations (EIM) (OR 2.48, 95%, CI 1.11-5.54) and occasional alcohol consumption (OR 0.39, 95% CI 0.20-0.76). CONCLUSIONS Impaired disability is mainly correlated with disease activity, the presence of EIM and no alcohol consumption. Moreover, there is a strong correlation with patients' quality of life. Therefore, in clinical practice, greater awareness of IBD-related disability is needed to better manage patients' outcomes.

Abstract
Ulcerative colitis (UC) may severely limit patients' capacity to work. Recently, we validated a work disability questionnaire (WDQ) for Crohn disease. As UC shares clinical characteristics with Crohn disease, we hypothesized that the questionnaire might also be useful for UC. The study was aimed to validate the WDQ for use in UC.Consecutive patients with UC (n = 142, 67 women; age 48 ± 1) completed the UC-WDQ and the inflammatory bowel disease questionnaire-9 (IBDQ-9), and EuroQoL-5D quality-of-life questionnaires. Validation of the UC-WDQ included an assessment of its construct validity, including: discriminant validity, convergent validity, and reproducibility (test-retest). We also calculated the intraclass correlation and the Cronbach alpha.The UC-WDQ is a valid and reliable tool for measuring work disability in patients with UC.

Abstract
Background The central sensitization inventory (CSI) comprises 25 items and is commonly used to measure somatic and emotional symptoms related to central sensitization symptoms. CSI was developed as an easy-to-administer screening instrument for patients at high risk of developing central sensitization in whom it was essential to quickly evaluate the condition. The purpose of the present study was to develop a short form of CSI and evaluate its psychometric properties using a contemporary approach called Rasch analysis. Methods A total of 505 patients with musculoskeletal disorders were recruited in this study. The CSI, pain intensity, pain interference, and the health-related quality of life (QOL) were evaluated for each participant. The original CSI items were consecutively analyzed using the Rasch model. Successive Rasch analyses were performed until a final set of items satisfied the model fit requirements. We also analyzed the psychometric properties of the original and short forms of CSI. Results Four consecutive Rasch analyses identified the removable items. Finally, the shortest questionnaire obtained that maintained the correct psychometric properties based on the Rasch model contained only 9 items (CSI-9). Rasch analysis showed that the CSI-9 had acceptable internal consistency, exhibited unidimensionality, had no notable differential item functioning, and was functional on the category rating scale. Conclusions The nine-item short form of CSI has acceptable psychometric properties and is suitable for use for patients with musculoskeletal pain. Thus, the CSI-9 can be used as a brief instrument to evaluate central sensitization.
