  The Chiral Confining Lagrangian, based on the chiral theory with quark
degrees of freedom, is used to study the spectroscopy of scalar mesons. The
formalism does not contain arbitrary fitting parameters and takes into account
infinite number of transitions from meson-meson to quark-antiquark states.
Starting from known $q\bar q$ poles the transition coefficients ensure the
strong shift of the poles for the $\pi\pi$ and much smaller shift for the
$K\bar K$ systems. The resulting amplitudes $f_{\pi\pi}$ and $f_{K\bar K}$ are
calculated in terms of the $q\bar q$ and the free meson Green's functions. With
the account of the $\pi\pi/K\bar{K}$ channel coupling one obtains two
resonances: a wide resonance $E_1$ in the range 500-700 MeV and narrow $E_2 $
near 1 GeV, which can be associated with $f_0(500)$ and $f_0(980)$. A similar
analysis, applied to the $I=1$ channel, shows that in this case two very close
poles in different sheets appear near $E=980$ MeV, which can be associated with
the $a_0 (980)$ resonance. The obtained $\pi\pi$ interaction amplitudes,
$\operatorname{Re} f_{\pi\pi} (E)$ and $\operatorname{Im} f_{\pi\pi}(E)$ are
compared with the known data.
