Results show that the CLQ possesses strong psychometric properties in both languages, and that the English and French versions of the CLQ appear to measure identical constructs.
However, the observed correlations have not been high enough to be able to state that they measure identical constructs (Banati and Diers, 2016; Casas, Baltatescu, Bertrán, González, and Hatos, 2013; Diener, et al. 1999; Nilsen and Bacso, 2017).
Despite measuring identical markers of the respiratory signal, RPM-gated CT is accomplished retrospectively on triggers at peak inspiration in the RPM trace following image acquisition[45], whereas RPM-gated PET is achieved prospectively on the same peak inspiration triggers to define the gating cycle during image acquisition[57, 58].
Thus the four metrics had logical relationships to each other, but did not measure identical constructs.
The domains of CRQ and SGRQ do not measure identical aspects of HRQL even though their total scores correlate highly.
These correlations support thematic agreement, but also suggest that the two instruments may not be measuring identical constructs (Table 6).
Therefore, it should not be surprising to find a relatively poor agreement between the measures of both techniques, since they do not measure identical properties of bone tissues.
These two approaches cannot be considered to measure identical constructs and research findings confirm a moderate correlation only [ 42, 66- 69].
When measuring identical respiratory gases from the automated calibrator, the three gas analysis systems measured by Gore's team produced a mean CV <1 % for VO2, VCO2, and VE.
The level of agreement between the identical sets of O2 and CO2 analyzers when measuring "identical" mixed expired gas (simultaneous) was impressively low at 0.1 0.3 % for both APE and CV, indicating that the auto-gas calibration routine and performance of the ParvoMedics gas analyzers were extremely precise.
