Now, why do we want to study and
examine psychological disorders?
Well, it’s kind of
important because one,
you need to identify and better understand
what are the symptoms associated with each,
and then next figure out sort of well, what
is the prevalence or how common is this
because as we’ll see today,
there is a whole slew of different
It’s not so cut and dry.
You have lots of overlap, you
have a whole bunch of variety,
and it is almost overwhelming
to try and to asses somebody
and try and establish what
physical disorder they might have
because you need a good understanding
of the symptoms associated with each.
And then you need to figure out
well, how do I treat that
once you’ve identified it,
and then how common is this.
So how do we do that and how
is this all documented?
Well, we have the
bible, which is the DSM
or the Diagnostic and Statistical
Manual of Mental Disorders
and it’s put up by the American
And they’ve had several renditions
and this has been around for years,
and the most recent one that’s out
right now is the DSM 5 or the DSM V.
And what it does is it actually
tries to categorize and outline
all the different types of psychological
and mental disorders and it defines them.
It’ll talk about the pathogenesis,
it’ll talk about what are some of
the characteristics that you see,
treatment options, might
even mention prevalence.
And so it’s a way to say well, it’s
in the DSM so this is, you know,
A) legitimate and B) because it’s documented
I’d have some better understanding
of the variables and
characteristics around it
and it might also have
some treatment options.
So the DSM is adapted to align with
current evidence and practice.
And what we’re saying here is that
they keeping out with newer versions
as we begin to understand more.
So that being said, the DSM really hasn’t
changed a lot over the last few years.
I think this, the gap between the most
recent version of the DSM 5 and the IV
was I believe almost 20
years, so I think 19 years.
So in that 19 years it’s not
like we’ve rewritten the book.
We’ve simply added a few
things, rejigged the
of our understanding,
but the idea is we have one
placed where somebody can go to
and really try to figure out
what it is that’s ailing you.
We also have something else called the
International Statistical Classification
of Diseases and Related Health
Problems called the ICD,
a lot easier to say ICD
than that whole name,
and was put out by the
World Health Organization.
And so for that, the most common
or recent version is the ICD 10.
And again, what we do here
is we have different codes
and a map of all the different
disorders and how they’re linked.
And so as a psychologist
or a physician,
you can write down the ICD code for, say
for example, somebody is suffering from
generalized anxiety disorder,
that would have an ICD code.
You can see where it fits in
the grand scheme of things.
You could refer to the DSM 5 and look at
some of the characteristics and symptoms
to make sure they they
align with your assessment
of your patient who’s
in front of you.
