On August 1st 2007 the IAPH changed from being the IAH. It changed from being 'The International Association of Hypnoanalysts', to 'The International Association of Pure Hypnoanalysts'.
The IAH had been the IAH since 1984, and for all that time, the name was entirely appropriate. By about 2005 though, the term 'hypnoanalysis' had become so generic and diluted that it had just lost all its meaning: what was in the late 1970's a very specific hypno-analytical process, was becoming 'just another hypnotherapy technique'. This change occurred, ostensibly, because more and more hypnotherapy schools were being set up and because these schools weren't 'loyal' to an analytical approach, the quality of the therapy started to suffer...
IAH, now IAPH, Members remained entirely focussed on the effectiveness of 'Pure' hypnoanalysis (that's hypnoanalysis with no other techniques or therapeutic 'tools' thrown in) and under Rob Kellys leadership, the therapy has become more and more 'Pure'...
It made absolute sense then, when we needed to differentiate between normal hypnoanalysis, and the 'Pure' hypnoanalysis that we practise, to change our name to The International Association Pure Hypnoanalysts.
