music playing DR. WAYNE FUQUA: My name is Wayne Fuqua. I’m a professor of psychology at Western Michigan University. And I’d like to welcome you to another installment of the Michigan Autism Tutorial Training series. And this is a series of tutorialtapes designed to illustrate the application of.
Behavior analysis and psychological interventions and assessment techniques to some of the problems experienced by children, adults, and adolescents on the autism spectrum. And today we’re very fortunate to have with us Doug Woods, who is a professor of psychology at Texas AM University. And Doug is going to be talking with us today.
About the assessment and treatment of habit disorders and tic disorders in children, Including those on the autism spectrum. So Doug, welcome very much. We’re very glad to have you here with us today. DR. DOUG WOODS: Thanks for having me, Wayne. I appreciate the invitation. WAYNE: Absolutely. Can you start off by telling us a little bit about what habit disorders entail and the range of activities?.
Because some people think of habit disorders as well, i’ve got a bad habit of staying up too late or eating too much. But you’re thinking of something more specific. DOUG: Right. Habit disorders is a fairly broad term, and you actually don’t find it in the psychiatric nomenclature. It’s an old term actually, but it’s still fairly useful in terms of how we conceptualize things. So really when we talk about habit disorders, we’re talking about things like tic disorders, which we’ll talk about probably in a little bit more detail later.
We’re talking about things that are typically considered what we would call bodyfocused repetitive behaviors. Things like chronic hair pulling, which is known as trichotillomania, or chronic skin picking, which is very closely associated with trichotillomania, or things like nail biting or biting on the insides of your cheeks, those kinds of things. WAYNE: OK. And this is distinctly different than things like selfstimulatory behavior for a child.
With developmental disabilities or selfinjury. is that correct, doug? DOUG: Correct. Selfinjury is a much more severe form of behavior. Obviously by it’s very name of selfinjury it’s guaranteed to cause some damage physically to the body. Habit disorders can result in that that can be one negative effect, but it’s not kind of the defining feature. And stereotypy is just usually a little bit different, because the form of the behavior in stereotypy really doesn’t change. It’s fixed. And that’s what makes stereotypy a little bit different than a traditional habit disorder.
And keep in mind that habit disorders in general are fairly normal in typically developing kids. It’s not an uncommon behavior, it’s just when it gets to be too frequent or too intense that it becomes problematic. WAYNE: It sounds like a good distinction actually, Doug. Now, over the last decade or two or however long, Doug, you’ve done extensive work in the area of habit disorders.
Would you tell us something about how you got involved and interested in the area? It’s kind of an interesting niche that you’ve worked in over the last few years. DOUG: Yeah. It definitely hasn’t been a common area in al psychology. I’m a trained al psychologist, so it hasn’t been common in our area. Although people see it a lot, they just haven’t really paid much attention to it in the realm of al psychology or behavior analysis for that matter.
Forestry Commission Hand and Arm Vibration Syndrome
(music playing) (Music playing) (Sound of Chainsaw) Hello my name is Neil Gresswell and I work for the Forestry Commission’s Health and Safety department I’m traveling today to meet Gareth Hopkins of our training department, Learning Development.
We’re going to discuss the contents of a seminar to support OGB 38 Hand Arm Vibration Syndrome management. (At the training centre in Cannock Chase) Morning Gareth. Morning Neil how is it going mate. Good journey? Alright? You all setup? I think so, I wouldn’t mind having a quick run through before we start, If that’s ok? (GH) Good idea (NG).
Right gareth ogb 38 we are just looking at the havs stuff where are we going to start this seminar do you think? I thought we would need to set the ground rules and tell people what HAVS is really. Right start with the explanation of HAVS. (NG) That would be good (GH) (music playing) Hand and Arm Vibration Syndrome is an injury to the blood vessels caused by vibrating machinery.
It damages the blood vessels and stops blood flowing to the extremities which can be extremely painful. and once the damage is done it is irreversible. (GH) Right Gareth good explanation of HAVS and what it is, where next? (NG) Thought we need to introduce OGB 38 and the management systems contained within it. (GH) Good (NG) Go through all the systems and make sure people know what is detailed in OGB 38. (GH).
Where are you going to start in ogb 38? its quite a big publication. (ng) We’re going to start with the 2 pieces of information to put in our management system that actually gives us our vibration levels. (GH) Which one first? (NG) The vibration magnitude of the machine that we are actually working with. (GH) Main points (NG) Main points, they will have to get the information from the manufacturer, weather they get that from the handbook.
Or getting in touch with the manufacturer or websites. Making sure if there is 2 or 3 magnitude levels they take the highest one. Some times there are 23 handles on a piece of equipment. and also reinforce the manufacturer has produced these figures for us but they were for brand new machines in workshop styles, straight out of the box basically (GH) (music playing) To work out the magnitude level of a piece of machinery.
First you must find the owners manual If you do not have a paper copy of the owners manual most owners manuals these days can be downloaded from the internet. In this example we have an owners manual for a Husqvarna 357 chainsaw. (GH) Once you have the owners manual you can navigate your way to the technical data section. Once you have navigated to the technical data section of the manual.
You need to find the section containing the vibration levels. in this manual we find the figures under the vibration section of the technical data we can also tell these are the right figures as the vibration magnitude is quoted in meters per second (m2) In this example as with all multihandle vibration tools the manufacturers will quote vibration levels for each handle. To enter in the calculator we will always take the highest figure thus erring on the side of safety. So for this example we will use a magnitude level of 4.2 m2 to enter into the HAVS calculator. (GH).
