We study dense hadronic matter in a generalized relativistic mean field approach which contains nonlinear couplings of the {sigma}, {omega}, {rho}, {delta} fields and compare its predictions for properties of neutron stars with the corresponding results from different models found in the literature. Our predictions indicate a substantial modification in static global properties of nuclear matter and neutron stars with the inclusion of the {delta} meson into the formalism.
