The pattern of quite strong correlations among the subscales is supportive of the construct validity of the PIPP, given the expected relationship among the various aspects assessed.
Indeed one might imagine that in practice there would be quite strong correlations, on the basis that a patient who responds well to one treatment might respond relatively well to the other, and similarly for costs.
Given that they were subjective quality of life constructs, quite strong correlations were expected between the subjective dimensions of quality of life measured by the QLQ-C30 and QLQ-BR23 (emotional functioning, social functioning, etc).
As expected, there were quite strong correlations between the YW-BCI36 and the QLQ-C30 and QLQ-BR23 scores (r ranging from 0.20 to −0.66), indicating adequate concurrent validity.
In our study, serum copper showed a weak but significant positive correlation with CA 125, but a quite strong negative correlation with c-erbB-2 and IGF-I levels.
We found quite a strong correlation between baseline level of MMP3 and final radiographic score and with 10-year radiographic progression.
The observed relationship was quite strong, with a correlation coefficient of 0.9, meaning that 1-ppb increase of the ambient NO will increase the nasal NO with 0.9 ppb.
The scatterplot of biogeochemical variables derived from the model run versus the independent fisheries statistics indicates that there is a quite strong and significant correlation between the variables, even if the strong temporal autocorrelation of the time series is taken into account [ Pyper and Peterman, 1998].
The Zener anisotropy, c44/c′, increases with increasing Ni contents, but is quite small, indicating a strong correlation between the softening of c44 and c′ with decreasing temperature during martensitic transformation (MT).
