We present new measurements of CP-violation parameters in B-0 ->phi K-0, (K+K-KS0), f(0)(980)K-S(0), eta'K-S(0), omega K-S(0), and K-S(0)pi(0) decays based on a sample of 275 x 10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. The combined result for the B-0 ->phi K-0, (K+K-KS0), f(0)(980)K-S(0), eta'K-S(0), omega K-S(0), K-S(0)pi(0), and previously reported (KSKSKS0)-K-0-K-0 decays differs from the SM expectation by 2.4 standard deviations.
