BACKGROUND The Timed Up and Go (TUG) test is quick and easy tests to assess patients' functional mobility. However, its reliability in individuals with knee osteoarthritis (OA) has not been well established. The aims of this study were to determine the reliability and minimal detectable change of the TUG test in individuals with doubtful to moderate (Grade 1-3) knee OA. METHODS Sixty-five sub...

BACKGROUND Global performance rating is frequently used in clinical training despite its known psychometric drawbacks. Inter-rater reliability is low in undergraduate training but better in residency training, possibly because residency offers more opportunities for supervision. The low or moderate predictive validity of global performance ratings in undergraduate and residency training may be ...

We present a new model-based approach to the analysis of agreement between raters in a situation where all raters have supplied dichotomous ratings of the same cases in a sample. The model is a logistic regression model with random effects--a Rasch model. In the rater setting, the Rasch model includes parameters that allow raters to have different propensities to score a given set of individual...

OBJECTIVE to verify the inter and intra-rater reproducibility of the Brazilian adapted version of the Edmonton Frail Scale (EFS) in an elderly group of residents. METHOD in order to test the inter-rater reproducibility, two assessments were independently conducted by two researchers on the same day but at different times, in a sample of 103 elderly. Concerning the intra-rater reproducibility,...

Previous studies have emphasized the importance of rater issues in studying the etiology of variation in internalizing and externalizing problems in children. Earlier results indicate only moderate agreement between parents, and assume that parents assess a specific aspect of their child's behavior. In comparable samples of younger children, additive genetic effects are the main factor explaini...

BACKGROUND The Wolf Motor Function Test (WMFT) evaluates the upper limb (UL) performance of adults with hemiparesis by combining time and quality of movement measures in both isolated movements and functional tasks. OBJECTIVES To translate and adapt the WMFT form, functional ability scale (FAS) and manual to Brazilian Portuguese and evaluate the intra and inter-rater reliabilities. METHODS ...

Objective: To find the inter-rater reliability of dentists from various specialties regarding observation and interpretation angle impacted third molars on OPG. Methodology: A cross sectional comparative study was conducted in College Dentistry, Sharif Medical Dental College, Lahore after obtaining ethical clearance committee Research Centre (SMRC) which four different namely; Oral Pathology, E...

"Three hundred and sixty-degree feedback" ("360") is the popular name for performance feedback collected from multiple raters. In the typical 360 process, supervisor(s), subordinates, peers, and (less frequently) internal or external customers provide feedback on performance for each target ratee, using some type of standardized instrument (London & Smither, in press; Tornow, 1993a). The ratee ...

In studies of child psychopathology, phenotypes of interest are often obtained by parental ratings. When behavioral ratings are obtained in the context of a twin study, this allows for the decomposition of the phenotypic variance, into a genetic and a non-genetic part. If a phenotype is assessed by a single rater, heritability is based on the child's behavior as expressed in the presence of tha...
