As an extension of our previous study, we derive slow-roll conditions for
multiple scalar fields which are non-minimally coupled with gravity and for
generalized gravity theories of the form $f(\phi,R)$. We provide simple
formulae of the spectral indices of scalar/tensor perturbations in terms of the
slow-roll parameters.
