Gillette Functional Assessment Questionnaire 22-item skill set: factor and Rasch analyses (original) (raw)
BMC Pediatrics
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...

years, y=46 7, SD=20.0) with neurological and musculoskeletal impairments. The pu?pose of the study was to determine whether the hierarchical scales of the motor p@ormance tasks between the pediatric and adult disability samples were congruent. Correlations of task dzficulty calibrations (r=. 76; Pc.01) and task rank ordm'ng (rho =. 76; P<.OI) were moderately high and positive between pedi-at& and adult subjects. SigniJcant age-group d~ferences emerged in relation to a number of individual motor performance tasks. In general, mobility and ambulation tasks were relatively easier for children, whereas manipulation tasks were relatively easier for adults. The data suggest a strong similarity in the overall pattern of motor p@ormance task dzficulty for children and adults. The results support the use by physical therapists of two parallel versions of the TAMP to describe the motor perfomnce of adults and school-aged children with physical disabilities.

Generic ABILHAND questionnaire can measure manual ability across a variety of motor impairments
International Journal of Rehabilitation Research, 2011
ABILHAND is, in its original version, a 46-item, 4-level questionnaire. It measures the difficulty perceived by patients with rheumatoid arthritis as they do various daily manual tasks. ABILHAND was originally built through Rasch analysis. In a later study, it was simplified to a generic 23-item, three-level questionnaire, showing both cross-cultural (Belgium vs. Italy) and cross-impairment (rheumatoid arthritis vs. stroke) validity. Later research returned to the development of impairment-specific versions, with modified item sets and levels. Each version has its own Rasch-derived item difficulty calibrations, which are required to extract the patient's measure from the individual string of responses, through computerized algorithms. All of these hamper the practical application of the scale in rehabilitation units, where patients with diverse conditions may share similar impairments and treatment approaches. In this study through Rasch analysis the 'generic' scale was applied to 126 chronic patients with different upper limb impairments, and to 24 healthy controls. It was supported that the generic questionnaire remains valid across a variety of motor impairments. To further facilitate clinical application, a normative cut-off ( > 79 of 100) is suggested. Rasch-based item calibrations are provided together with a software routine designed to calculate, on individual patients, linear 0-100 measures and error estimates from the raw scores.
A psychometric evaluation of the Arm Motor Ability Test
Journal of Rehabilitation Medicine, 2013
Objective: To further examine the psychometric properties of a 9-item version of the Arm Motor Ability Test (AMAT-9) in persons with stroke. Subjects: Thirty-two community-dwelling persons > 6 months post-stroke undergoing robotics treatment (mean age = 56.0 years, time post-stroke = 4.1 years, National Institutes of Health Stroke Scale score = 4.1, and AMAT-9 score = 1.22). Methods: Construct validity (including Rasch analyses) used baseline data prior to treatment (n = 32). Standardized response mean was calculated for subjects completing the protocol (n = 29). The Wolf Motor Function Test (WMFT), Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), and Stroke Impact Scale (SIS) were also administered. Results: Spearman-rank correlation coefficients between AMAT-9 and the WMFT, FMA, and ARAT were strong (0.78-0.79, all p < 0.001). The correlation between the AMAT-9 and SIS Hand Function sub-score was stronger than that between the AMAT-9 and the Communication subscore (0.40, p = 0.025 and-0.16, p = 0.39, respectively). Rasch analyses provided evidence for an appropriate hierarchical structure of item difficulties, unidimensionality, and good reliability. The AMAT demonstrated a comparable standardized response mean of 0.98. Conclusions: The AMAT-9 is valid and responsive among subjects scoring in the lower range of the scale. It has the advantage of assessing function and by eliminating the standing item from the previous iteration, it may be more easily used with severely impaired patients.

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.

Objectives: Information obtained from families is of particular importance in the evaluation of functional mobility skills of children with cerebral palsy (CP) after orthopedic interventions and long-term rehabilitation applications. This study was designed to evaluate the interobserver reliability of the Gillette Functional Assessment Questionnaire (FAQ) which was administered to the mothers and the physiotherapist for children with CP. Methods: The study included 52 spastic diparetic children with CP (22 girls, 30 boys; mean age 7.8±4.4 years; range 4 to 12 years) and their mothers. According to the Gross Motor Function Classification System (GMFCS), all the children were in level 1 to 3. The Gillette FAQ was administered to the mother and physiotherapist to determine the functional walking level of the child and the interobserver reliability of the FAQ was calculated. In addition, gross motor performance was evaluated by the standing and walking-running-jumping dimensions of the Gross Motor Performance Measure (GMPM), and functional independence level was evaluated by the transfer and locomotion dimensions of the Functional Independence Measure for Children (WeeFIM). Correlations were sought between the FAQ results of the physiotherapist and mothers and the GMFCS, GMPM, and WeeFIM. Results: The intraclass correlation coefficient for interobserver reliability of the Gillette FAQ was 0.94 (95% CI 0.898-0.966). A highly significant correlation was found between the responses of the mother and physiotherapist to the Gillette FAQ (r=0.882, p<0.01). The responses of the mother and physiotherapist to the Gillette FAQ showed a negative correlation with the GMFCS level, and positive correlations with the dimensions of the GMPM and WeeFIM studied (p<0.01). Conclusion: The Gillette FAQ can be used by the physiotherapists to determine the functional changes in spastic diparetic children with CP and can help clinicians derive important information from the families about functional walking of their children.

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.
