We study higher--derivative supergravity with curvature squared terms in different bases. Performing a Weyl rescaling only on the metric or on all the superfield components does not allow to obtain a normalized kinetic Einstein term from a \cR+\cR2 theory. It is necessary to combine a Legendre transformation and a Weyl rescaling on a \cR+\cR2 theory to arrive at a theory of supergravity coupled to matter. This mechanism is applied to supergravity coupled to a general function k(R,\BR,Φ,Φ), where R is one of the supergravity chiral superfields and Φ a chiral matter superfield.
