We have calculated the total Gamow-Teller strength S/sub +- / in the even-even sd-shell nuclei making use of the sum rule technique. The ground state wave function is obtained from the shell model calculation in the full (sd)/sup n/ space. It is shown that the proton-neutron correlation effect causes a considerable amount of reduction of the total Gamow-Teller strength. It is also shown that the reduction of the isospin component in S..sqrt.. induced by the configuration mixing becomes more significant with increasing isospin
