OBJECTIVE To improve, with the aid of psychometric analysis, the Balance Evaluation Systems Test (BESTest), a tool designed to analyse several postural control systems that may contribute to poor functional balance in adults. METHODS Performance of the BESTest was examined in a convenience sample of 115 consecutive adult patients with diverse neurological diagnoses and disease severity, refer...

The 39-item Parkinson's disease questionnaire (PDQ-39) is the most widely used patient-reported rating scale in Parkinson's disease (PD). However, recent studies have questioned its validity and it is unclear what scores represent. This study explored the possibility of regrouping PDQ-39 items into scales representing the International Classification of Functioning, Disability, and Health (ICF)...

BACKGROUND Patient-reported outcome measures evaluating shoulder disability after neck dissection have not been sufficiently validated. We assessed the psychometric properties of the Shoulder Disability Questionnaire (SDQ), Neck Dissection Impairment Index (NDII), and the Shoulder Pain and Disability Index (SPADI) in patients after neck dissection. METHODS One hundred seven patients completed...

A majority of research investigating aggression and its development in children relies on rating scales such as the Child Behavior Checklist (CBCL). These scales typically are developed using a conventional factor analytic approach for the selection and retention of scale items, but may contain insufficient items to assess the unidimensionality and developmental trajectory of youths’ aggressive...

Abstract Background With the implementation of competency-based education in family medicine, there is a need for summative end-of-rotation assessments that are criterion-referenced rather than normative. Laval University’s residency program therefore developed Developmental Benchmarks Scale Family Medicine (DBS-FM), based on competency milestones. This psychometric validation study investigate...

Guided by the theory of interpretive validity argument, this study investigated the plausibility and accuracy of five sets of warrants which were deemed crucial to the validity of a selfassessment (SA) scale designed and used in a local EFL context. Methodologically, this study utilized both the Rasch measurement theory and structural equation modeling (SEM) to examine the five warrants and the...

BACKGROUND painDETECT (PD-Q) is a self-reported assessment of pain qualities developed as a screening tool for pain of neuropathic origin. Rasch analysis is a strategy for examining the measurement characteristics of a scale using a form of item response theory. We conducted a Rasch analysis to consider if the scoring and measurement properties of PD-Q would support its use as an outcome measur...

conclusions the layout of whiteboard in classrooms can be effective in causing student’s neck pain. in this study, the suitable height of installation of whiteboard was determined and it is recommended to be used in classrooms. background the mismatch between equipments and anthropometric dimensions of users is one of the issues that can be effective on development of musculoskeletal disorders ...

OBJECTIVE The aim of this study was to investigate unidimensionality and differential item functioning of the SF-36 physical functioning scale (PF10) in patients with various neurological disorders. PATIENTS PATIENTS post-stroke (n = 198), with multiple sclerosis (n = 151) and amyotrophic lateral sclerosis (n = 193) participated. METHODS Unidimensionality of the PF10 within the patient grou...
