Background The purpose of this study was to translate, cross-culturally adapt and validate the Gillette Functional Assessment Questionnaire (FAQ) into Brazilian Portuguese. Methods The translation and cross-cultural adaptation was carried out in accordance with international recommendations. The FAQ was applied to a sample of 102 patients diagnosed with cerebral palsy (CP). Construct validity was assessed using Spearman’s correlation coefficient (rho), and the FAQ score was correlated with the Functional Mobility Scale (FMS) and Gross Motor Function Classification Scale (GMFCS). A subsample of 50 patients was used to assess reliability using intraclass correlation coefficient (ICC), standard error of measurement (SEM) and minimum detectable difference (MDD). Ceiling and floor effects were also evaluated. Results The Brazilian version of the FAQ showed excellent test-retest reliability by the assessment of the physiotherapist (ICC = 0.99) and respondent (ICC = 0.97), as well as excel...

Franchignoni F, Giordano A, Sartorio F, Vercelli S, Pascariello B, Ferriero G. Suggestions for refinement of the Disabilities of the Arm, Shoulder and Hand Outcome Measure (DASH): a factor analysis and Rasch validation study.To perform a comprehensive psychometric analysis of Disabilities of the Arm, Shoulder and Hand (DASH) to examine its properties and provide insights for an improved version.Methodologic research on cross-sectional data from a convenience sample.A free-standing rehabilitation center.Outpatients and inpatients (N=238; 56% men; mean age, 52.2y) with upper-extremity musculoskeletal disorders.The official Italian version of DASH was analyzed by factor (both explorative and confirmatory) and Rasch analysis for evaluating dimensionality, functioning of rating scale categories, item fit, hierarchy of item difficulties, and reliability indices.Not applicable.Factor analysis established the presence of 3 underlying constructs related to manual functioning (items 1–5, 7–11, 16–18, 20, 21), shoulder range of motion (items 6, 12–15, 19), and symptoms and consequences (items 22–30). Rating scale diagnostics showed category malfunctioning. The fit to the Rasch model was good for all items except 4 (items 20, 21, 25, 26). Ten item pairs had high residual correlations after subtraction of the Rasch dimension (local dependency). A test model based on the 3 subscales suggested by factor analysis and corrected categories still showed misfitting in items 21 (“Sexual Activities”) and 26 (“Tingling”) and the presence of some dependent items.Unidimensionality and the key domains identified by the original developers as the theoretic framework of DASH were not confirmed by our analyses. The response categories showed misfunctioning. “Sexual Activities” and “Tingling” misfit the Rasch model. Further detailed investigations of DASH are warranted, both to confirm these results in different health conditions and cultures, and to reanalyze in-depth content validity issues regarding the questionnaire.

The assessment of motor proficiency is essential across childhood to identify children’s strengths and difficulties and to provide adequate instruction and opportunities; assessment is a powerful tool to promote children’s development. This study aimed to investigate the hierarchal order of the Test of Gross Motor Development-Third Edition (TGMD-3) items regarding difficulty levels and the differential item functioning across gender and age group (3 to 5, 6 to 8, and 9 to 10 years old). Participants are 989 children (3 to 10.9 years; girls n = 491) who were assessed using TGMD-3. For locomotor skills, appropriate results reliability (alpha = 1.0), infit (M = 0.99; SD = 0.17), outfit (M = 1.18; SD = 0.64), and point-biserial correlations (rpb values from 0.14 to 0.58) were found; the trend was similar for ball skills: reliability (alpha = 1.0), infit (M = 0.99; SD = 0.13), outfit (M = 1.08; SD = 0.52); point-biserial correlations (rpb values from 0.06 to 0.59) were obtained.
