  Let $R$ be a local ring and $M$ a finitely generated $R$-module. The complete
intersection dimension of $M$--defined by Avramov, Gasharov and Peeva, and
denoted $\cidim_R(M)$--is a homological invariant whose finiteness implies that
$M$ is similar to a module over a complete intersection. It is related to the
classical projective dimension and to Auslander and Bridger's Gorenstein
dimension by the inequalities $\gdim_R(N)\leq\cidim_R(N)\leq\pd_R(N)$.
  Using Blanco and Majadas' version of complete intersection dimension for
local ring homomorphisms, we prove the following generalization of a theorem of
Avramov and Foxby: Given local ring homomorphisms $\phi\colon R\to S$ and
$\psi\colon S\to T$ such that $\phi$ has finite Gorenstein dimension, if $\psi$
has finite complete intersection dimension, then the composition
$\psi\circ\phi$ has finite Gorenstein dimension. This follows from our result
stating that, if $M$ has finite complete intersection dimension, then $M$ is
$C$-reflexive and is in the Auslander class $\catac(R)$ for each semidualizing
$R$-complex $C$.
