Chapter 5 Obsessional Disorders
Nature of the problem
Obsessions are the intrusive thoughts that then provoke
unpleasant feelings, standardly anxiety, that are then neutralised by the
compulsion. There are standardly some specific situations that trigger the
thoughts, although they might be so wide spread the actual originary situation
is lost, although there will definitely be modulators. The neutralising behaviour then gives some
temporary relief from the anxiety, although the obsession returns. Patients also develop avoidant behaviour to
avoid trigger situations.
Clinically OCD gets divided into obsessional rumination,
which is obsession with covert compulsion and obsessions with overt compulsions
(obsessional ritualizing)
Content of obsessions
Usually concerned with something personally repugnant
Types of compulsive behaviour
A theme common to OCD is future harm and a desire to prevent
it. Cleaning\checking compulsions more closely resemble phobias and have more
avoidant behaviour in them. When
avoidance fails then compulsion is used to neutralise. In checking obsessions the patient strives to
ensure he has not been responsible for harm coming to himself or others. There is a functional identity between cleaning
and checking, making sure I am not responsible for harm. Likewise overt
compulsions can be classified into restitution, i.e. putting things right and
verification i.e. checking.
The psychological model of obsessive compulsive disorder
Core features of obsessional problems are
1.
Avoidance of object which trigger obsessions
2.
Obsessions
3.
Compulsive behaviours and thought rituals
As the obsessions persist and rituals become extensive
patients can present with ritualistic behaviours apparently independent of the
obsession when confronted with an obsessional trigger, as the patient
neutralises before the obsession occurs.
Obsessions get associated with anxiety, i.e. conditioned,
the anxiety would decline naturally but is kept there by the compulsions, which
reduce the anxiety temporarily but the client never sees the anxiety dropping
so the conditioning remains. Again
avoidance maintains the anxiety as exposure to the thoughts occurs less often.
Assessment
A crucial aspect of assessment is the response to exposure
both within session and for homework as once the link between triggers,
thoughts, neutralising activities and avoidance are clear then the therapist
can implement a treatment plan.
Factors determining suitability for treatment
You need to establish if the OCD is primary or as a reaction
to a primary problem, if it’s the primary problem then this should be treated
first. The treatment is relatively straightforward once the detailed assessment
is complete and consists of exposure and response prevention. Schizophrenic patients often show OCD
symptoms
Find out how the problem has affected them over the last
week, i.e. intensity and duration, then move to a specific example of the
problem. Look for what triggers the behaviour and look to elucidate any
thoughts that there might be, or images.
Detailed behavioural analysis
Move to a specific example, and ask about the trigger
situations, go through cognitions, emotions, physiology and behaviour. Then ask
about the consequences, so do an ABC analysis.
Things to look for in analysis
1.
Avoidance
2.
Reassurance
3.
Modulators
4.
Forms of obsession, thoughts, images, impulses
5.
Triggers, emotional, cognitive
6.
Emotions, how they change, pre obsession, during
compulsion and post compulsion
7.
Development of problem
8.
Degree of impairment due to problem, in various
domains
9.
Cost benefit analysis of change
Covert neutralising
If a client’s obsessions are obscured by compulsions, then
try to get the client to provoke the obsession, or provoke it for them on an
assumption of what it is. Alternatively if there is a trigger situation that
forces them to compulsion then get that trigger situation done without the
compulsion.
Avoidance
There can be cognitive avoidance, as the client tries not to
think about something. This will prevent exposure from working. If the client doesn’t think their behaviours
are senseless or excessive then they are not obsessional, especially if they think
the origin of these behaviours are external, e.g. radio waves. When a client
sees their behaviour as reasonable but excessive then do a cost benefit, the
amount of effort put in for a highly improbable event.
Emotional factors
Check the mood associated with the obsession, the assumption
is its anxiety but many patients report it as discomfort, tension, anger or repugnance.
To clarify feelings, you can ask, is it like the feeling you get before an
exam, when you are fed up
Behaviours
Behavioural assessment is crucial any behaviours that trigger
obsessional thoughts. Prevent exposure
to them are crucial to be understood. Look at active and passive avoidance, so are
there things that prevent you having obsessions, are there things you avoid to
prevent you having obsessions. Sometimes
covert rituals are used when overt ones are not possible. The behaviours that
terminate exposure are reassurance and neutralising behaviours, you should be
aware of these before doing any exposure. Neutralising behaviours can be stored up, so
for eight hours you can’t neutralise, then you neutralise furiously. Modulators
can be situational, emotional, cognitive or interpersonal.
Other aspects of assessment
Check family members aren’t helping to maintain their
behaviours. Do a cost benefit analysis,
if you didn’t have this behaviour how would your life be different.
Behavioural tests
Get client to enter the compulsion provoking situation
without doing the compulsion and to note down what they’re thinking and what
they’re feeling without doing the compulsion. Often because clients have become
so used to their behaviour they omit salient details, so if you can do
something in session that is a trigger situation for them and then to see what
they do then that would be ideal for collecting all the information.
Difficulties in assessment
Obsessional thoughts are repugnant to the client and they
fear they will be rejected if people know they have them. Some patients may
think talking about their obsessional fears may make them worse. There can also
be shame and embarrassment about the compulsions.
Chronicity
A very chronic problem might lead to the client not wanting
to talk about their thoughts, through fear they may get locked up, seen as bad
etc. Here look at what the effect of having the thought is, I don’t want to be
locked up, then show how because you try to stop the thought because its
repugnant shows you won’t act on it, and also how thought suppression leads to
the enhancement and rebound effect.
Treatment of obsessions with overt compulsive behaviour
Presenting the rational
So you can use the dogs example, i.e. little boy gets scared
of dogs and as an adult crosses the road, does this help, what should we do?
When clients fear that the anxiety will not decline, then to say it will be
fine is counterproductive, rather use it to do another behavioural experiment.
Introduction to exposure
Clients are willing to endure high levels of distress if
they think the treatment will be effective. One of the things about exposure is
that it will produce anxiety but actually this is a good thing as you may well find
it goes down more rapidly than you thought between 20 -60 mins. The other thing you will find is after
repeating the same exposure the anxiety will reduce more quickly
Modelling is a useful way to show the client there is no
problem with doing what you are asking.
It can often help if the therapist goes beyond what they are asking the
client to do. Modelling should be used only at the start of treatment but should
be phased out as it can be used as a reassurance technique by the client.
If responsibility is an issue in terms of the client always
seeking reassurance that they have done the task right, then get them to set
their own homework, without telling the therapist, and get them to do a
homework review the next week.
Reassurance
Reassurance seeking is a common aspect of obsessions.
Reassurance seeking looks to ensure that harm hasn’t happened and has the
effect of passing the responsibility onto someone else. If the client does reassurance seeking in
session then do an ABC on it and see how much relief it provides, then look to
see what the long term picture is, does it actually maintain the anxiety. So to get the client to think about this, then
ask the client how much reassurance they would need to make the problem go away
for a month, if this doesn’t work then its ineffective. Reassurance prevents confronting and extinguishing
the anxiety that’s arisen about being responsible for harm. If relatives have problems with this then they
can say hospital instructions are that I don’t answer such questions.
Difficulties encountered in the course of treatment
Habituation does not occur in session.
If you get stuck with the client, then “There are two
problems we could be having, one that you are having problems with germs and
need to be obsessional with it, or two you are having obsessional problems which
are kept going by your compulsions, how do you think we could decide between these
possibilities.
Treatment of obsessions without overt compulsive behaviour
Covert compulsive behaviours are quite difficult to gain
access to and to control. However all
that needs to happen to the standard model is to recognise mental neutralising
behaviour. Indeed then the exposure is the repugnant thought, and the response
prevention is
Assessment
Discriminating between the obsessional thought and the
compulsive thought is critical. Intrusive involuntary thoughts need to be
discriminated from neutralising thoughts which are deliberately evoked. . There
also might be covert avoidance behaviour, such as thought suppression.
Treatment procedure
Habituation procedure
IN habituation training then you repeat predictably to
elicit thoughts to get anxiety reduction whilst preventing any neutralising
behaviours. The key here is predictable, so if there are certain triggers that
get the thoughts reliably created use these. From this point then move on to
unpredictable events.
Before any ERP is started though, the client must fully
understand the treatment rationale, the function of their compulsions and
avoidance.
To get the predictable thought then you can get the patient
to say the thought to themselves or to have a tape loop with their voice on
it. Get them to listen to the tape for
10 times without any neutralising behaviours, rate anxiety and urge to neutralise.
Repeat this every day for a week and see how the anxiety changes
Thought stopping
I’m not sure about this one, this seems like it could turn
into a safety behaviour but still…What you do is to get the client to describe
a pleasant scene or thought, then elicit a distressing thought for the client
and then shout stop and then get them to
think the more pleasant thought, I guess the sense of surprise will make them
change, then get them to say it to themselves. The thought stopping needs to be
practised in non-stressful situations until it can be used in stressful
situations.
First you direct proceedings then you get them to do it. I guess
one thing with thought stopping is the novelty of it wears off after a while, so
I guess some ingenuity should be used to make it still seem novel.
Alternative treatments
Behavioural treatment, is the treatment of choice. Psychotherapy is seen to be effective for
people with obsessional traits and not OCD. Learning as an in-patient can lead
to difficulties in generalisation when they leave hospital.
