Proof. Suppose M is a Prüfer module. Then by [10, Theorem 3.6], R is a Prüfer domain.
As R is an integral domain and M is a non zero faithful multiplication R-module, by [6, Proposition
3.4], M is finitely generated. Again by Lemma 5, every finitely generated submodule
of M is join-quasi-cyclic. The converse part follows from [6, Proposition 3.4], Lemma 5 and
[10, Theorem 3.6].
