Abstract Most general forms of the nonlinear selfcoupling of the scalar field in the relativistic mean-field model are discussed, the frequently used form where the scalar mass is field-dependent, and an alternative where the scalar coupling constant becomes field-dependent. Both models are shown to be fully equivalent in homogenous systems. They are practically equivalent in finite nuclei. Parametrizations in the nonlinear scalar coupling model which are constructed to avoid the nucleon-antinucleon instability at large densities fail to give a good description of common ground-state properties of finite nculei.
