The setupitemize command does not accept the setups key.

One workaround is to abuse the option key.

\setupwhitespace[5em]
\startsetups[smallwhitespace]
     \setupwhitespace[small]
     \setupblank[small]
\stopsetups
\unprotect
\setvalue{\??itemgroupkeyword SmallWhiteSpace}{\setups{smallwhitespace}}
\protect

\setupitemize[option=SmallWhiteSpace, indenting=no, inbetween={\blank[1cm]}]

\starttext
\input knuth

\startitemize
\dorecurse{5}{\item this is my item\par
                     second paragraph\par
                     third paragraph
                     }
\stopitemize
\stoptext

@Hans: Could you add a setups key to \startitemgroup? One could abuse the 
before key, but that is not always executed.
