sorry all...forgot the publication for MacCallum..that would be
Psychological Methods..................
You may be thinking of:
Cohen, J. (1983) The cost of dichotomization. Applied psychological
measurement, 7, 249-253.
And more recently, you may want to look at:
MacCallum, R.C., Zhang, S., Preacher, K.J, & Rucker, D. D. (2002). On the
practice of dichotomization of quantitative variables. 7, 19-40.

Is this what you were looking for?

I'm doing some research on dichotomizing symptoms and the information lost
when dimensional symptoms are dichotomized. I remember that there was a
paper called "The cost of dichotomizing" and I think it was by Stevens.
Does anyone know where I can find this article?
thanks.
