The researcher seems to be replacing a general hypothesis -
that there is a relation between belief in your ability to
lower your cholesterol and you success at doing so - with only
one of a number of operationalizations that are possible: that
mean cholesterol drop in those who scored above-median would
be greater than those who scored below-median.
What about exploratory data analysis? Is there a linear relationship,
that might be summarized using a regression? Are those who believe
in their power to control their diet more consistent in the
degree of reduction? (Is there any relationship between initial
cholesterol and the measure of confidence?). My guess is that the
psychological measure doesn't behave like a linear scale, but maybe
there is a score above which you have 'enough sense of control' and
variation above that doesn't matter.
I'm just strewing the page with possible interrelations that would
be of interest, that might exist and that haven't been checked
for. What I'd do first, though, is look at a scatterplot.

Happy christmas, you lot!
