A time-dependent method for studying the double-phonon states of giant resonances is proposed based on an extended version of the time-dependent Hartree-Fock theory known as the time-dependent density-matrix theory. The method is applied to the double phonon state of the isoscalar giant quadrupole resonance in ^<O>. It is found that the peak energy of the double phonon state is nearly twice the energy of the single phonon state calculated in the random phase approximation and that its width is slightly larger than that of the single-phonon state.
