Well, let's see:
1. Clinical Hypnotherapy
There's no such thing as "clinical hypnotherapy", at least in terms of any specific method, system, or techniques. I think "clinical hypnotherapy" can be the most effective, or not effective at all, depending on how it is used and who uses it.
2. Emotional Freedom Technique (EFT)
I don't much care for EFT. It isn't based on anything sensible like observation, and is mostly a placebo. Too rigid for me to call it "hypnosis".
3. Eye Movement Desensitization and Reprocessing (EMDR)
I've heard of EMDR before, wasn't much impressed. It sounds like a strange, NLP-like technique that might work, sometimes. They charge you a whole lot to go to seminars and learn about it, too, even though it's just one stupid technique.
4. Holographic Reprogramming
Like NLP, EMDR and others, this makes the assumption that your unconscious is something you can engineer or program. I don't see that as being the case. Computers don't have interests or desires, don't make choices, and don't have relationships. Humans are more complex, and believe it or not we're living beings; animals.
5. Avatar
I could not find any information on this, period.
6. Psych-k
Apparently Psych-K is some combination of the 'programming' metaphor and a not-well-defined idea of spirituality. It sounds interesting, just not likely to be very practical. They aren't very forthcoming on descriptions of how it works, guess you gotta pay to find out.
7. Body Talk.
This sounds like a bastardized version of Feldenkrais and EFT. I like Feldenkrais classic better, at least they actually pay attention to
where muscular tension is actually occurring rather than foaming at the mouth about energy meridians while ignoring what the person is actually doing.
I'm amazed that NLP isn't on that list, although it's basically similar to many of those. I'd say NLP includes a lot more critical thinking and basic sense, even if it isn't all that effective in practice. They didn't mention Cal Banyan's "5-Path" either, although that could probably fit under "clinical hypnotherapy". I kinda like 5-Path, although it only seems to have 3 paths, he charges 10-path prices and gives himself a parade on his about page.
