Abstract: We study the crossed product $ A \rtimes G \supseteq B \rtimes G$ of an inclusion $ A \supseteq B$ of type $ {\text{I}}{{\text{I}}_1}$-factors by a discrete strongly outer action $ G$. In particular, we find conditions under which the strong amenability of $ A \supseteq B$ implies that of $ A \rtimes G \supseteq B \rtimes G$, and vice versa.
