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.Abstract:
Minimal measurement error (reliability) during the collection of interval- and ratio-type data is critically important to sports medicine research. The main components of measurement error are systematic bias (e.g. general learning or fatigue effects on the tests) and random error due to biological or mechanical variation. Both error components should be meaningfully quantified for the sports physician to relate the described error to judgements regarding ‘analytical goals’ (the requirements of the measurement tool for effective practical use) rather than the statistical significance of any reliability indicators.read more

Test-retest reliability of the assessment of postural stability in typically developing children and in hearing impaired children.
TL;DR: Test-retest reliability of centre of pressure (COP) measurements obtained by an AccuGait portable forceplate, mean COG sway velocity measured by a Basic Balance Master and clinical balance tests in children with and without balance difficulties was established.

Does the demand for asymmetric functional lower body postures in lateral sports relate to structural asymmetry of the pelvis
TL;DR: It is demonstrated that potentially there is an association between the asymmetrical nature of lateral dominant sports and pelvic skeletal asymmetry, however, there are possibly two confounding variables in age of initial participation and presence of low back pain that require further exploration.

Testing single and double limb standing balance performance: Comparison of COP path length evaluation between two devices
TL;DR: The COP path length displacements obtained from the GKS balance system seem to differ with a considerable random variability from Kistler force platform data, and measurements of the evaluated devices should not be used interchangeably.

Consensus on measurement properties and feasibility of performance tests for the exercise and sport sciences: a Delphi study
Sam Robertson,Sam Robertson,Peter Kremer,Brad Aisbett,Jacqueline Tran,Ester Cerin,Ester Cerin +6 more
TL;DR: The checklist developed from this study can be used to inform decision-making and test selection for practitioners and researchers in the exercise and sport sciences and can facilitate knowledge sharing and performance comparisons across sub-disciplines.

Psychometric evaluation of the internalized stigma of mental illness scale for patients with mental illnesses: measurement invariance across time.
TL;DR: The clinical implication of the finding is that clinicians, when they design interventions, may want to use the valid and reliable ISMI without the Stigma Resistance subscale to evaluate the internalized stigma of people with mental illness.

Statistical methods for assessing agreement between two methods of clinical measurement
TL;DR: In this article, an alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability, which is often used in clinical comparison of a new measurement technique with an established one.

A concordance correlation coefficient to evaluate reproducibility.
TL;DR: A new reproducibility index is developed and studied that is simple to use and possesses desirable properties and the statistical properties of this estimate can be satisfactorily evaluated using an inverse hyperbolic tangent transformation.
