In this paper, we study S-Principal ideal multiplication modules. Let (Formula presented.) be a commutative ring with (Formula presented.) a multiplicatively closed set and (Formula presented.) an A-module. A submodule N of M is said to be an S-multiple of M if there exist (Formula presented.) and a principal ideal I of A such that (Formula presented.). (Formula presented.) is said to be an S-principal ideal multiplication module if every submodule (Formula presented.) of (Formula presented.) is an S-multiple of M. Various examples and properties of S-principal ideal multiplication modules are given. We investigate the conditions under which the trivial extension (Formula presented.) is an (Formula presented.) -principal ideal ring. Also, we prove Cohen type theorem for S-principal ideal multiplication modules in terms of S-prime submodules.
