Table 3. Fitness characteristics of factor solutions obtained from Dog Owners (n = 59978) and Veterinary Health Practitioners (n = 1436) surveys.

The data was randomly split in halves: Exploratory Factor Analysis was performed on one half to identify factors and tested on the other half by Confirmatory Factor Analysis. The random split was repeated 10 times to further investigate the stability of identified factors. Values are reported as mean ± standard deviation for the 10 random splits.
