It is not the same as the significance value but of course it is related as that is how significant the result is!

Basically, it is a measure of how strong the evidence is.

if I get a value of 0.000 for the significant value on spss can I report this as 0.000?

I would presume so, it has no effect on the dependent variable.

Hi, a p value of 0.000 would in theory, be interpreted as "the probability of your two sets of results being DIFFERENT due to chance is zero" - in other words, it implies that there is DEFINITELY (=100%) a difference between your test results and your placebo results. Such a result NEVER occurs in any live experiment, as perfection is [especially in a biomedical experiment, in which variability is intrinsically engrained], by definition, impossible.

I would be inclined to set your SPSS to give a result to a greater degree of accuracy e.g. to 5 or 6 decimal places, in which case you might end up with a p value with a more realistic meaning e.g. 0.00005!
