There’s a very good article regarding JONAH in particular and reparetive therapy in general that touches on Dr. Spitzer as well, in Dialogue Vol 3 Fall 2012.
The dialogue Journal is reviewed by Rav Shlomo Miller, Rav Feldman, and Rav Moshe Meiselman and features articles on Homosexuality by Rav Ahron Feldman as well as Rabbi Hillel Godlberg.
The arilce about the clinical aspects is written by Dr. Elan Karten Ph.D.
I think you’ll find it pretty enlightening.
