We use an expansion in T/sub c//T/sub F/ to study the influence of strong-coupling effects on the linear response of superfluid /sup 3/He. Our results indicate that the enhancement of the order parameter gives the major strong-coupling corrections to the magnetic susceptibilities, bending energies, and superfluid density. The additional ''nontrivial'' strong-coupling corrections depend sensitively on currently unknown details of the quasiparticle interactions. Hence, precise measurements of the response coefficients can provide additional information about the quasiparticle interactions.
