please provide full working examples, not only fragments.

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

\begin{document}

\def\psFBox#1{\rput[lC](5pt,-4pt){\psframebox{#1}}%
  \rput[lC](2pt,-1pt){\psframebox[fillstyle=solid,fillcolor=white]{#1}}%
  \psframebox[fillstyle=solid,fillcolor=white]{#1}}
\begin{psmatrix}
foo\\
\psFBox{\tabular{c}streamflow\\index ($Q$)\endtabular}\\
bar
\end{psmatrix}
\ncline{->}{1,1}{2,1}
\ncline[nodesepA=6pt]{->}{2,1}{3,1}

\end{document}

hope, it helps
