Insert the following nested fields in your document. Each pair of {} needs
to be the special field code braces that you can insert using ctrl-F9 - you
can't just type them. Change mybox to the name of your field and substitute
the appropriate symbols where I have typed <unchecked box character> and
<checked box character>.

{ IF "{ MERGEFIELD "mybox" }" = "False" "<unchecked box character>"
"<checked
box character>" }

This assumes that you are using Word 2002/2003/2007 and have not altered the
way it connects to Access. if you are using DDE (the default in Word
97/2000) or ODBC, then you need

{ IF "{ MERGEFIELD "mybox" }" = "0" "<unchecked box character>" "<checked
box character>" }

Or if for example you are just using a text field with Y and N for "True"
and "False", use

{ IF "{ MERGEFIELD "mybox" }" = "N" "<unchecked box character>" "<checked
box character>" }
