Due to the increased repair work on one of the classical instruments, it was necessary to choose the ROI's carefully so as to reflect the true wood density, not that of the repair.
To assess the construct validity of the Brazilian version of the instrument, it was necessary to verify how well the measures the underlying construct being investigated.
Prior to instrument application, it is necessary to perform a background measurement to enable subtraction of noninterferometric and common path interference signals from the captured spectra, I. Before the endoscope is placed into the polycarbonate tube, the signal I R is captured.
However, in order to compare both instruments regarding utility values, it is necessary to develop a new scoring algorithm for the EQ-5D+C by conducting a general population study.
In considering the ongoing process of validation once the instrument has been developed, it is necessary to specify the interpretations and applications that we are seeking to validly and reliably achieve.
However, with some instruments, such as the DTSQc, it is necessary to modify the instructions to relate specifically to the conditions of the clinical trial in which it is being used and we now have considerable evidence to show that the psychometric properties of the DTSQc remain robust to such changes [ 5, 6].
To visualize moderate differences, it is necessary to have instruments that are highly sensitive to clinical change.
To have a higher spatial resolution, it is necessary to use other instruments at synchrotron radiation facilities [26].
As the risk of substance related problems in university students is high, it is necessary to have screening instruments that can be used beyond the health care settings.
