Lecture 6
- Obsessive-compulsive disorder:
- → obsessions and compulsions are recurrent and persistent;
- → individual recognises they are excessive or unreasonable;
- → obsessions/compulsions are cause marked distress, are time consuming (>1
hr/day spent on engaging in ritualistic behaviour or thought process) and significantly
interfere with functioning and relationships (might be difficult for somebody to eat in
public or attend university or leave the house)
- These disorders lie on continuum in terms of distressing nature in terms of impact on
individual
-
- Obsessions: persistent ideas, thoughts, impulses, or images that are experienced as
intrusive and inappropriate and cause marked anxiety or distress (can be counter to
what they think of themselves or horrific images or thoughts, can’t switch it off/no
matter what one does image pops into mind); individual recognises thoughts are
product of their own mind(where part of the distress that is inherent in OCD comes
about, differentiate between OCD and symptoms of psychotic disorders)
- Someone with psychotic illness might feel data projector is sending them a message
and message comes from data projector, not themselves or may feel that someone is
implanting ideas/thoughts in their mind
- Obsessions: common types - fears of contamination; repeated doubts (safety,
scruples [removing plugs, switching lights or microwave off]); need to have things in a
particular orders [can’t skip a step before moving on to next one, wash dishes in
order]; sexual, horrific or blasphemous imagery; aggressive or inappropriate
impulses; nonsensical thoughts or images

- Compulsions: repetitive behaviour (handwashing, checking) or mental acts (praying,
counting, repeating words silently) the goal of which is to prevent or reduce anxiety
(associated with obsession; obsessive thoughts of contamination [infect family with
chicken pox] → scrupulously clean/wash hands to prevent risk of contaminating
family → successfully reduces anxiety until next time of intrusive thought or they
doubt whether they have done repetitive behaviour properly [did they scrub
fingernails as much as should have to eradicate chances of contaminating family →
go back and do it all again, start from step 1]); can include rigid/stereotyped acts
according to elaborate rules without any real explanation of them
- Sometimes pairings of obsession-compulsion loosely speaking has logical threat
[unplug microwave so it doesn’t burn down house], but doesn’t explain why one has
to go back and check 30 times within 5 minute period or doubt whether washed
hands properly; at times seems to have logical linking between the two but doesn’t
explain presentation of individual
- Sometimes doesn’t seem to have logical link between obsessive thought and
compulsion - had horrific imagery of family members being hurt → muscle tensing in
order in whole body [no way that tensing pectoral muscle has relation to mother
being hit by train]
- Compulsion common types - washing and cleaning; checking; repeating; ordering;
mental rituals (e.g. counting, prayers); reassurance seeking; hoarding; compulsive

shopping (overt to covert behaviours)
-
- Up to 80% of population may experience intrusive, unpleasant, unwanted thoughts;
more than 50% population may engage in ritualised behaviour (Crino. Slade, &
Andrews 2005), Australian data
- May be engaged in something and a thought comes out of seemingly left field that
isn’t related to what is being done at the point in time - can be distracting, unpleasant,
unwanted → don’t engage in thought [can say that was weird or put aside on focus
on something else]

Sometimes pairings of obsession-compulsion loosely speaking has logical threat. Compulsion common types - washing and cleaning; checking; repeating; ordering; mental rituals (e. g. counting, prayers); reassurance seeking; hoarding; compulsive shopping (overt to covert behaviours) Up to 80% of population may experience intrusive, unpleasant, unwanted thoughts; more than 50% population may engage in ritualised behaviour (crino. Someone with ocd does not have capacity to reject the intrusive thought or saying that"s not important at the moment/pushing it aside, doesn"t have capacity to check just once. About 1% of adult population experiences ocd, mid-20s, early/mid adulthood.
