I would like to conduct a mediation analysis with cox regression.  I have
turnover data and survival times.  Here is how the mediation is theorized...

occupational experience ---> perceived job fit ---> survival


occupational experience ---> organization expectations ---> survival

Using linear regression, most researchers would recommend following Baron
and Kenny's (1986)approach.  This 4 step approach tests for mediation, and I
am wondering whether the same 4 step approach to test for mediation applies
to a survival analyis.  Is this correct?  Is there another approach that is
recommended to conduct mediated cox regression?  Any cites that apply would
be greatly appreciated.
Thanks - Jon C
