RESULTS:
CFA applied to data of the total sample, elementary school students subsample and new-old adults subsample, indicating that individual variability across [R] CPM measured variables (total scores for each of the three sets) can be modeled by one latent variable (a single underlying factor). The same pattern of [R] CPM latent structure was not verified for the subsamples of kindergarten students and old-old adults, since the variance of a single underlying factor was not found to be statistically significant.
