Accuracy in measurement relates to the utility, interpretability, and generalizability of given values, associations, and outcomes. Accuracy is obtained through rigorous empirical methods and testing across a wide spectrum of patient populations. Confirmatory factor analyses, cluster analysis, and structural equation modeling often have to be employed to establish evidence of accuracy in measurement. Establishing accuracy evidence is a dynamic and ongoing process that never stops.
From a psychometric standpoint, accuracy is related to the validity of a given measure. Convergent, predictive, concurrent, and known-groups validity coefficients can provide measures of validity when tested in a nomological or theoretical framework with similar instruments in the area of interest. Validity is established in a dynamic and ongoing process, just like accuracy.
Being able to generalize and infer measurements in published science to the immediate clinical environment is another aspect of accuracy. Outcomes that are measured for at the "gold standard" level provide the most accuracy for clinicians looking to integrate evidence. Accurate measurements that appear in the literature often should be replicated in other research studies.
The most synonymous words with accuracy are validity, interpretability, and generalizability.
