choose "empty lines" inside the psmatrix for the nodes.

\documentclass{article}
\usepackage{pstricks-add}

\begin{document}
   \begin{psmatrix}[rowsep=0.8,colsep=0.4]
     [name=X1] & \\[-25pt]
               & \dianode{S}{Condition1?}\\[0pt]
               & \rnode{SA}{\psframebox{do something}}\\[-25pt]
     [name=X2] & \\[0pt]
               & \dianode{R}{Condition2?}\\[-10pt]
     [name=Y2] &
   \end{psmatrix}%
       \psset{arrows=->,nodesep=0pt}
       \ncline{S}{SA}\nbput{Yes}
       \ncline{SA}{R}
     \psbrace[ref=r,rot=180,nodesepA=-8pt](X1)(X2){Stage 1}
     \psbrace[ref=r,rot=180,nodesepA=-8pt](X2)(Y2){\parbox{2cm}{Stage 2 very
       looooooong text}}
\end{document}
