Aims: Effective measurement of clinical outcomes is dependent on reliable outcome instruments. Measurement error and reliability testing are fundamental underpinnings of reliability. This article defi nes and illustrates sources of measurement error, outlines strategies for error minimization, and gives an overview of the types of reliability studies. Content: The two main sources of measurement error: systematic bias and random error, are discussed. The three major types of reliability… Expand

Understanding the common inter-rater reliability measures
Health and rehabilitation professionals use a range of outcome instruments to evaluate the effectiveness of their interventions. In order to be evidenced-based practitioners, we need to understandExpand
How to read and critically appraise a reliability article
Background: This article is a guide to critically appraising reliability studies based upon fundamental reliability concepts. It focuses on reliability studies of physical measurement instrumentsExpand
Psychometric Evaluation of the Brachial Assessment Tool Part 1: Reproducibility.
TLDR
Findings support the use of the BrAT as a reproducible patient-reported outcome measure for adults with traumatic BPI with evidence of appropriate reliability and agreement for both individual and group comparisons. Expand
Are Ultrasound Measurements of Achilles Tendon Size Reliable? A Systematic Review of Rater Reliability.
TLDR
It is revealed that good to excellent intra- and inter-rater reliability can be achieved for ultrasound measurements of Achilles tendon size and Reporting of reliability studies needs to be improved by the use of existing reporting guidelines and expansion of these guidelines to include important elements of ultrasound imaging. Expand
The use of evidence-based guidance to enable reliable and accurate measurements of the home environment
TLDR
This evidence-based guidance can be used in its current format by older people and professionals to facilitate appropriate measurements, yet, some users might need help from carers or specialists depending on their impairments. Expand
The reliability of rehabilitative ultrasound to measure lateral abdominal muscle thickness: A systematic review and meta-analysis.
TLDR
RUSI variables for the LAM at rest show moderate-to-excellent reliability; future research should explore reliability following the proposed RUSI protocol. Expand
Inter- and intra-rater reliability of a technique assessing the length of the Latissimus Dorsi muscle
TLDR
The poor to moderate reliability of the technique testing the length of LD test is not suitable for application in a research setting, but the small differences noted between Reading 1 and Reading 2 regarding the standard deviation of all the raters combined suggests that the LD length test may still prove to be useful in quantifying dysfunction in a clinical setting. Expand
Perceived Barriers, Enablers and Modifications to Tests Assessing Pediatric Lower Limb Neurological Impairment: An International Delphi Survey.
TLDR
High levels of consensus support the use of lower limb neurological testing in a range of pediatric neurological conditions and barriers and enablers to pediatric neurological testing are identified. Expand
Italian Validation of a Test to Assess Dysarthria in Neurologic Patients: A Cross-Sectional Pilot Study
TLDR
The protocol showed to have potential clinical utility to assess dysarthria in neurological patients, due to its completeness and ease of training and administration and Lin’s Concordance Correlation Coefficient determined the consistency of measurements between the same rater and among different raters with different levels of expertise. Expand
Clinimetric properties of lower limb neurological impairment tests for children and young people with a neurological condition: A systematic review
TLDR
Limited high-quality clinimetric evidence exists for lower limb neurological impairment tests in children and young people with a neurological condition, therefore, results of currently used neurological tests should be interpreted with caution. Expand

Statistical Methods For Assessing Measurement Error (Reliability) in Variables Relevant to Sports Medicine
TLDR
It is recommended that sports clinicians and researchers should cite and interpret a number of statistical methods for assessing reliability and encourage the inclusion of the LOA method, especially the exploration of heteroscedasticity that is inherent in this analysis. Expand

TLDR
The general concepts of agreement and reliability are distinguished to aid researchers in considering which are relevant for their particular application, and the fact that reliability depends on the population in which measurements are made, and not just on the measurement errors of the measurement method is highlighted. Expand
A psychometric toolbox for testing validity and reliability.
TLDR
Planning for psychometric testing through design and reducing nonrandom error in measurement will add to the reliability and validity of instruments and increase the strength of study findings. Expand
Quality criteria were proposed for measurement properties of health status questionnaires.
TLDR
The criteria can be used in systematic reviews of health status questionnaires, to detect shortcomings and gaps in knowledge of measurement properties, and to design validation studies. Expand
Impact of patient-reported outcome measures on routine practice: a structured review.
TLDR
Regular use of patient-reported outcome measures by health care providers in their routine practice may help to improve the quality of care, but more evidence is needed before routine use of PROMs can be recommended. Expand
Reliability and Validity Assessment
TLDR
The paper shows how reliability is assessed by the retest method, alternative-forms procedure, split-halves approach, and internal consistency method. Expand
Improving the reliability of orthopaedic measurements.
TLDR
In making clinical decisions, orthopaedic surgeons rely heavily on measurements obtained from the patient’s history, physical signs and radiological examination, and the importance of measurement reliability can be illustrated with an example of a child with scoliosis. Expand
[Reliability and validity of the upper limb DASH questionnaire in patients with distal radius fractures].
TLDR
DASH is a workable, reliable and valid instrument for patients with Colles' fractures and could discriminate patients with different fracture types, according to test criteria. Expand
Measuring the whole or the parts? Validity, reliability, and responsiveness of the Disabilities of the Arm, Shoulder and Hand outcome measure in different regions of the upper extremity.
TLDR
It is demonstrated that the DASH had validity and responsiveness in both proximal and distal disorders, confirming its usefulness across the whole extremity. Expand
Development of an upper extremity outcome measure: The DASH (disabilities of the arm, shoulder, and head)
TLDR
The goal is to produce a brief, self-administered measure of symptoms and functional status, with a focus on physical function, to be used by clinicians in daily practice and as a research tool. Expand
