Attenuation is the concept that is defined as the decrease in magnitude of the validity coefficient associated with measurement error of the predictor, the criterion, or both. It occurs when the true score is not perfectly measured, and the observed score is used instead, which contains error. This results in an underestimation of the true relationship between the predictor and criterion.
