  "abstract": "We derive the consistency relations for chaotic inflation model with a non-minimal coupling to gravity. For a quadratic or quartic potential in the limit of a small non-minimal coupling parameter $\\xi$, we give consistency relations among spectral index $n_s$, the tensor-to-scalar ratio $r$ and the running of the spectral index $\\alpha$. We find that unlike $r$, $\\alpha$ is less sensitive to $\\xi$. If $r<0.1$, then $\\xi$ is constrained to $\\xi<0$ and $\\alpha$ is predicted to be $\\alpha\\simeq -8\\times 10^{-4}$ for a quadratic or quartic potential. For general monomial potential, $\\alpha$ is constrained in the range $-2.7\\times 10^{-3}<\\alpha< -6\\times 10^{-4}$ as long as $|\\xi|\\leq 10^{-3}$ if $r<0.1$.",
