We investigate the decays of {chi}{sub c0,2} into vector meson pairs (VV), pseudoscalar pairs (PP), and scalar pairs (SS) in a general factorization scheme. The purpose is to clarify the role played by the OZI-rule violations and SU(3) flavour breakings in the decay transitions, and their correlations with the final-state meson wavefunctions. For {chi}{sub c0,2}{yields}VV and PP, we obtain an overall self-contained description of the experimental data. Applying this factorization to {chi}{sub c0}{yields}f{sub 0}{sup i}f{sub 0}{sup j}, where i,j=1,2,3 denotes f{sub 0}(1710), f{sub 0}(1500) and f{sub 0}(1370), respectively, we find that specific patterns will arise from the model predictions for the decay branching ratio magnitudes, and useful information about the structure of those three scalars can be abstracted.
