I don't see the main effect of sex on your /DESIGN line.  You need it too.
I.e.,

  /DESIGN= sex coping1 coping2 coping3 coping4 coping5 coping6
                sex*coping1 sex*coping2 sex*coping3 sex*coping4 sex*coping5
sex*coping6


I would also add a "/PRINT parameter" sub-command to get the table of
regression coefficients.
