CONTEXT Neither reliability nor validity data exist for the Root method of clinically assessing first ray position or mobility by experienced and inexperienced examiners. OBJECTIVE To determine intrarater and interrater reliability for first ray position and mobility measurements in experienced and inexperienced examiners. DESIGN Single-blind prospective reliability study. SETTING Physica...

Dental and dental hygiene faculty members often do not provide consistent instruction in the clinical environment, especially in tasks requiring clinical judgment. From previous efforts to calibrate faculty members in calculus detection using typodonts, researchers have suggested using human subjects and emerging technology to improve consistency in clinical instruction. The purpose of this pil...

This article argues that the general practice of describing interrater reliability as a single, unified concept is at best imprecise, and at worst potentially misleading. Rather than representing a single concept, different statistical methods for computing interrater reliability can be more accurately classified into one of three categories based upon the underlying goals of analysis. The thre...

BACKGROUND There are over 165,000 mHealth apps currently available to patients, but few have undergone an external quality review. Furthermore, no standardized review method exists, and little has been done to examine the consistency of the evaluation systems themselves. OBJECTIVE We sought to determine which measures for evaluating the quality of mHealth apps have the greatest interrater rel...

Objective. The Tuck Jump Assessment (TJA), a clinical plyometric assessment, identifies 10 jumping and landing technique flaws. The study objective was to investigate TJA interrater and intrarater reliability with raters of different educational and clinical backgrounds. Methods. 40 participants were video recorded performing the TJA using published protocol and instructions. Five raters of var...

OBJECTIVE To assess the intrarater and interrater reliability among rheumatologists of a standardised protocol for measurement of shoulder movements using a gravity inclinometer. METHODS After instruction, six rheumatologists independently assessed eight movements of the shoulder, including total and glenohumeral flexion, total and glenohumeral abduction, external rotation in neutral and in a...

Twenty studies examining the reliability of assessment devices and outcome measures in therapeutic research were reviewed and analyzed. The 20 investigations contained 215 quantitative reliability values published in either the American Journal of Occupational Therapy or Physical Therapy during the past 5 years. The reliability studies were classified as interrater, intrarater, test-retest, or ...

The kappa statistic is frequently used to test interrater reliability. The importance of rater reliability lies in the fact that it represents the extent to which the data collected in the study are correct representations of the variables measured. Measurement of the extent to which data collectors (raters) assign the same score to the same variable is called interrater reliability. While ther...

BACKGROUND Visual estimation (VE) and goniometric measurement (GM) are commonly used to assess first metatarsophalangeal joint dorsiflexion. The purposes of this study were to determine the intrarater and interrater reliability of VE and GM and to establish whether reliability was influenced by the experience of the examiner. METHODS Ten experienced and ten inexperienced examiners evaluated t...
