BACKGROUND To develop a culturally adapted and validated Bengali Short Form SF 12v2 among Rheumatoid arthritis (RA) patients. METHODS The English SF 12v2 was translated, adapted and back translated into and from Bengali, pre-tested by 60 patients. The Bengali SF 12v2 was administered twice with 14 days interval to 130 Bangladeshi RA patients. The psychometric properties of the Bengali SF 12v2...

A 1H magnetic resonance spectroscopic imaging study at 3T and short echo time was conducted to evaluate both the reproducibility, as measured by the interscan coefficient of variation (CV), and test-retest reliability, as measured by the intraclass correlation coefficient (ICC), of measurements of glutamate (Glu), combined glutamate and glutamine (Glx), myo-inositol (mI), N-acetylaspartate, cre...

Objectives. The purpose of this study was to determine the validity and reliability of the Persian version of the children’s active play imagery questionnaire. Methods. For this purpose, 190 athletic children of the average age of 11.5 years were chosen through random sampling and they completed the Persian version of the children’s active play imagery questionnaire (CAPIQ).

Numerous exploratory, proof-of-concept and interventional studies have used histaminergic and non-histaminergic human models of itch. However, no reliability studies for such surrogate models have been conducted. This study investigated the test-retest reliability for the response to histamine- and cowhage- (5, 15, 25 spiculae) induced itch in healthy volunteers. Cowhage spiculae were individua...

OBJECTIVE We aimed to develop a questionnaire assessing fears and beliefs of patients with knee OA. DESIGN We sent a detailed document reporting on a qualitative analysis of interviews of patients with knee OA to experts, and a Delphi procedure was adopted for item generation. Then, 80 physicians recruited 566 patients with knee OA to test the provisional questionnaire. Items were reduced acc...

OBJECTIVE The reliability and validity of the Test of Visual-Perceptual Skills (Non-Motor)-Revised (TVPS-R) were examined for its usefulness on Hong Kong Chinese preschoolers. METHOD Content validity was evaluated by six experts. Test-retest reliability, construct validity, and criterion validity were examined on 66 typically developing preschoolers while concurrent validity was examined on t...

The intraclass correlation coefficient (ICC) is widely used in many fields, including orthodontics, as a measure of reliability of quantitative data. The main goals of this study were to determine the multivariate intraclass correlation, a measure of intra-rater reliability, for the selection of 6 3D mid-facial soft tissue landmarks and compare the multivariate ICC with other measures of landma...

OBJECTIVE This study aimed to translate and culturally adapt the Falls Risk Awareness Questionnaire (FRAQ) for the elderly Brazilian population as well as to evaluate the internal consistency and reliability of this instrument. METHOD The study used internationally accepted guidelines for the cross-cultural adaptation process. The questionnaire in its final Portuguese version was then applied...

BACKGROUND The PedsQL™3.0 Diabetes Module is a widely used instrument to measure the disease-specific health-related quality of life summary measures in children and adolescents with type 1 diabetes. After cultural adaptation, we confirmed reliability and validity of PedsQL™3.0 Diabetes Module in its Italian version. METHODS Participants were 169 Italian children and adolescents with type 1 d...

PURPOSE The purpose of this study was to determine the reliability of interpupillary distance (IPD) and pupil diameter (PD) measures using an infrared eye tracker and central point stimuli. Validity of the test compared to known clinical tools was determined, and normative data was established against which individuals can measure themselves. METHODS Participants (416) across various demograp...
