Help to interpret bootstrap and sobel results from spss

[gi.yair]

Hi,
I'm trying to understand the meaning of these results -
my hypothesis is that EA mediates between CNFU and PI.
Is the mediation full or partial?
What does the insignificance of CNFU mean?
What else can I learn from these results?

I haven't used this procedure before so the output is a little unfamiliar, but this looks like you have a case of partial mediation per David Kenny's revised criteria for mediation. The relationship between X (CNFU) and Y (PI) is reduced after controlling for M (EA), and in fact becomes non-significant, but is not reduced to zero (which would be required for a claim of complete mediation).
