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

\documentclass{article}

\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}
