  We compare the linear meson model and chiral perturbation theory in next to
leading order in the quark mass expansion. In particular, we compute the
couplings L_4--L_8 of chiral perturbation theory as functions of the parameters
of the linear model. They are induced by the exchange of 0^{++} scalar mesons.
We use a phenomenological analysis of the effective vertices of the linear
model in terms of pseudoscalar meson masses and decay constants. Our results
for the L_i agree with previous phenomenological estimates.
