In addition, two judges were asked to evaluate the SOC measure in order to determine the presence or absence of emotionality. The results suggest that the SOC measure lacks face, construct, and predictive validity in terms of simple mediation and stress moderation models. In addition, sex of ...
It is noted that 'validity is a matter of degree, not all or none... and that over time the existing validity becomes enhanced (or contravened) by new findings.' Convergent (supporting) and discriminant (contradictory) evidence are also defined in terms of test validation and it is ...
As multimorbidity becomes common that imposes a considerable burden to patients, but the extent to which widely-used multimorbidity indexes can be applied to quantify disease burden using primary care data in China is not clear. We applied the Chinese Multimorbidity-Weighted Index (CMWI) to health...
Face validity is a criterion of subjective assessment to determine whether a test or any other measurement procedure used in a study measures what it claims to, based on face value. It is the simplest type of validity to use in research. However, it is based on the idea of reading through...
The first conclusion from this research is that the number of signals the DeM indicators produce is small and rarely occurs. Compared to a simple buy-and-hold strategy, their results show that, in most cases, there is a limited range of holding days for which the indicators have predictive ...
The calculations evidence rather good similarity when systems bearing the two different R groups are compared in terms of geometry, relative energies, and the ion-pair separation energies. They validate to a large extent the −CH2SiMe3 group as a model of the growing chain in catalytic olefin...
The validity of selection tests is underestimated if it is determined by simply calculating the predictor-outcome correlation found in the admitted group. This correlation is usually attenuated by two factors: (1) the combination of selection variables which can compensate for each other and (2) ra...

The condition for the validity of ATDHF consists in requiring the collective kinetic energy per particle to be small compared with an average single-particle energy divided by a simple matrix element representing the coupling between collective and non-collective degrees of freedom. Finally, this ...
In order to quantify the importance of the different levels for ICD coding, we calculated the median odds ratio (MOR) [8, 9]. The MOR translates the higher level variance into the widely used odds ratio (OR) scale which has a consistent and intuitive interpretation. In simple terms, the ...
