IAPT base treatment on problem descriptors not standardised diagnosis, resulting in a gross failure to identify appropriate treatment targets. A recent study by Thomlison et al (2017) indicated 4 out of 5 PTSD cases were missed. There is no evidence that identification of other disorders is any more reliable Scott (2018) see earlier post (link below)
In the Thomlinson et al study (2017) three quarters of IAPT clients were in low intensity groups, conducted without reference to any explicit evidence based protocol. This looks like playing a numbers game with groups.
