  We study the strong and electromagnetic decay properties of scalar mesons
above 1 GeV within a chiral approach. The scalar-isoscalar states are treated
as mixed states of quarkonia and glueball configurations. A fit to the
experimental decay rates listed by the Particle Data group is performed to
extract phenomenological constraints on the nature of the scalar resonances. A
comparison to other theoretical approaches in the scalar meson sector is
discussed.
