We determine the effective gravitational couplings in superspace whose
components reproduce the supergravity Higgs effect for the constrained
Goldstino multiplet. It reproduces the known Gravitino sector whilst
constraining the off-shell completion. We show that these components arise by
computing the effective action. This may be useful for phenomenological studies
and model building: We give an example of its application to multiple
Goldstini.
