This was illustrated by the finding that 32% of the patients in the non-intervention group reported clinically significant improvement afterwards.
IAPT justifies itself wholly in terms of changes on psychometric tests, alleging a 50% recovery. However there has been no independent examination to determine the proportion totally free of symptoms by the end of treatment. My own work in fact suggests just a 10% recovery,https://www.dropbox.com/s/flvxtq2jyhmn6i1/IAPT%20The%20Need%20for%20Radical%20Reform.pdf?dl=0 . In mid July the Journal of Health Psychology is publishing an Open Access Special Issue ‘IAPT Under the Microscope’ in which these issues are explored further, with 4 contributors, including myself and a missive from the Editor, Dr David Marks.
