This strikes me as the wrong question. Find out what formula SPSS
uses. So far, in this thread, you've claimed that you found one
formula for ICC in an article, and you referred to the ICC1 function
from multilevel which uses a different formula. We still don't know
exactly how SPSS is making its calculation.
The formulae that R routines use are in plain sight for you to
inspect. If SPSS would offer you the same courtesy, then we would not
be left in this weird situation of trying to guess what they mean by
some number.
