In this paper we consider loop corrections to the spin-independentWIMP-nucleon scattering cross section in bottom-quark flavored scalar-type darkmatter models. We focus on two scenarios: (a) a complex scalar dark matter witha scalar particle as the mediator; and (b) a real scalar dark matter with avector boson as the mediator. In both scenarios, the direct detection crosssections are either spin-dependent or kinematically forbidden at thetree-level. Corrections induced by the WIMP-gluon effective operator,scalar-type WIMP-quark effective operator, and the twist-2 effective operatorare calculated. Numerical results show that loop induced spin-independentWIMP-nucleon scattering cross sections are quite considerable in bothscenarios.
