What to Do With “Moderate” Reliability and Validity Coefficients? [PDF]

Archives of Physical Medicine and Rehabilitation, 2016
Clinimetric studies may use criteria for test-retest reliability and convergent validity such that correlation coefficients as low as .40 are supportive of reliability and validity. It can be argued that moderate (.40-.60) correlations should not be interpreted in this way and that reliability coefficients

Validation and Analysis of Bounce Resonance Diffusion Coefficients [PDF]

Journal of Geophysical Research: Space Physics, 2018
AbstractTheoretical bounce resonance diffusion coefficients for waves generated near the equatorial plane are analyzed theoretically and validated numerically using guiding‐center test particle simulations. A previous study demonstrated numerically the sensitivity of the diffusion coefficients to the peak wave normal angle and the maximum wave latitude

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Evaluating concurrent validity using correlation coefficient for selected physical abilities

Tanjungpura Journal of Coaching Research
Background Validity is a fundamental concept in test development and evaluation, ensuring that a test measures what it is designed to measure. One type of validity is concurrent validity, a subtype of norm-related validity, which assesses how closely
