Interesting. Can you tell me about the specific protocol for addressing arachnophobia using CBT? What kinds of things did they have you do? How long did it take to overcome the phobia? I'm sure the end result had to be a huge accomplishment for you. Very liberating. Bravo!!
I meant that I was the (assistant) therapist. The university/major I graduated at is know for it's CBT based work/teaching. Every year we had the "spider project". Used to partially do new research on the other hand subject would get free therapy. Since the deal was that we had to find as many spiders as possible to use in the project ,fear of spiders would be a problem (not to mention get you hooked up to a lot of research

.
It's been a while but the short version is that you start by explaining fear and the fact that fear gets bigger if you leave a situation that you are afraid of before the fear begins to subside. Simply put if you put fear on a 1-10 scale and you run away every time your fear goes up to 7, then you leave and the fear goes down, you keep getting afraid and you reinforce the idea that there IS something to be afraid of and that leaving is helping. Lather, rinse repeat.
With exposure you "force" people to stay in the situation even if the fear gets up to 7-8-9-10. What happens is that after a while the fear starts to go down, even if you are still in the situation that you are afraid of. So you start disconnecting fear from the object that you are afraid of. (see you can be "relaxed" in the presence of a spider). With spider phobics you would for instance start by taking a spider that elicits a fear of about 6 at a 10 foot distance, you wait till the fear goes down to a 4 and then you take a couple of steps closer, next step is to put the spider in a bucket and look up close, next is touching with a stick, then touching with your finger, then lwt it walk on your hand. Do the same thing but then with bigger spider etc. The trick is to keep doing something that elicits a reasonable amount of fear and then wait till it subsides. At the same time you talk about (mis)conceptions about spiders, show that you are able to do t without the spider going out and killing you etc.
One important aspect is that you "over train" your subjects. There will always be a little setback after therapy since clients will not have their therapist with them afterwards or the "high" wears off. So with spider phobics would would ultimately have them handle big (say tarantula style) spiders at the end of the day. Even with a setback, at home you'd still be able to vacuum up a spider, or put it outside without going berserk.
With spiders the protocol was around 3-4 hours, with a success rate very close to 100%. The worst case scenario was usually when someone wouldn't completely get rid of their fear, or not take as many steps up as others. I haven;t seen anyone where it made NO difference. The only thing that the client HAS to do is stay in the presence of the fear no matter what, the fear WILL subside. If you bail, then it won;t work.
You can use the same protocol with any kind of phobia, also with a lot of obsessive compulsive disorders. And there are some really interesting stories there: afraid of fish, so afraid of touching dirt that you can't clean, Having to check if the light if off when you are IN the room (think about that one

). Afraid that if you shake someones hand the following might happen (from a male perspective) : You masturbate and accidentally some sperm gets on your hand and survives washing, if you then shake the hand of a female and the sperm would jump over and then she masturbates and get pregnant and then has an abortion, you are responsible for the death of a fetus. Not to make light of these because the can be debilitating but it just proves how interesting the mind is.
ETA: strangely exposure does not work if you are repulsed by something. So fear of spiders yes, but grossed out by spiders no. Not sure if they figured out why yet.
Also, I've always heard that if you are afraid of spiders you are never afraid of mice and vice versa, wonder if that is true?
What is going to be important is knowing exactly what it is you are afraid of and being exposed to that fear/ For instance if you are afraid of spiders, other insects might elicit some fear as well, but being exposed to centipedes for hours is not going to do anything for your fear of spiders. This sounds simple but actually is not. With spiders people are afraid of different things, some the long legs, some the short and hairy legs, some a small body, some the big body, some the form, some the speediness. So in order to be effective you have to find the RIGHT spiders to work with.
With your fear you'd have to figure out with your therapist what it is EXACTLY that you are afraid of in order for exposure to be effective, this gets more difficult as phobia's get more complex. For instance if you are afraid of groups: are you afraid people look at you funny, or are you afraid that you will faint and embarrass yourself, or are you afraid of running out of oxygen? the same basic description "fear of groups" would describe all of them. Fear of heights is also somewhat unclear.
I'm gonna stop now and let someone else get a word in edgewise
