. The disturbance is not better explained by the symptoms of another mental disorder…
what are the types of specific phobia?
animal (e.g., spiders, insects, dogs),
natural environment (e.g., heights, storms, water)
blood-injection-injury (e.g., needles, invasive medical procedures).
situational (e.g., airplanes, elevators, enclosed places)
other (e.g., situations that may lead to choking or vomiting).
what is the criteria for a social phobia
A. Marked fear or anxiety about one or more social situations in which the individual is exposed to possible scrutiny by others.
B. The individual fears that he/she will act in a way or show anxiety symptoms that will be negatively evaluated.
C. The social situations almost always provoke fear or anxiety.

what are the types of social phobia
Performance situations (e.g., public speaking)
General (e.g., eating in public)
what is the prevelence of phobias
Lifetime prevalence around 12%.
More common in women than men.
Most patients with specific phobia have at least one other excessive specific fear.
Most patients with social phobia suffer from one or more additional anxiety disorders.
what are the psychodynamic theories of phobias
Freud (1909): Phobias result when unconscious anxiety is displaced onto a neutral or symbolic object.
Hans’ Oedipal fears of his father – or perhaps of his desire to kill his father – became unbearable and were displaced onto horses
what are behavioural theories of phobias
Phobias are conditioned fear responses.
Ost and Hugdahl (1981): 58% of phobic clients cited traumatic conditioning experiences as the source of phobia.
McCabe et al. (2003): 92% socially phobic adults reported a history of severe childhood teasing (cf. 35% OCD sufferers).
Vicarious classical conditioning. Rhesus monkey expts.
outline a biological explanation of phobias
Prepared learning: Primates seem evolutionarily prepared to rapidly associate certain objects with frightening or unpleasant events.
Prepared fears are not innate but easily acquired and resistant to extinction.
Ohman et al: Fear conditioned more effectively to snakes and spiders than flowers and mushrooms.
give two types of therapy for phobias

Phobia (fear, aversion) Philia (attraction)
Paraphilias- Unusual sexual interests
what are qualities of a paraphilia
Compulsive quality
- Vary in severity

Paraphilias involve a (sometimes exclusive) focus on a specific object, act or situation for sexual gratification. Need not cause harm
what is a paraphillic disorder
Paraphilic disorders: atypical sexual activities/preferences that cause harm to the individual or others.

Outline OCD
Occurrence of unwanted and intrusive obsessive thoughts or distressing images
Compulsive behaviours performed to neutralise the obsessive thoughts or images or to prevent some dreaded event or situation
Obsessive-Compulsive Disorder (OCD)
Occurrence of unwanted and intrusive obsessive thoughts or distressing images
Compulsive behaviours performed to neutralise the obsessive thoughts or images or to prevent some dreaded event or situation
What does a person with OCD Feel?
Driven to perform a compulsive ritualistic behaviour in response to an obsession
The need to follow very rigid rules regarding how the compulsive behaviour should be performed
How do the DSM define it?
Recurrent and persistent thoughts, impulses or images that are experienced as intrusive, disturbing, inappropriate and uncontrollable.
Person attempts to resist, suppress or neutralise them with some other thought or action
Person recognises they are a product of his or her own mind
give some frequent types of obsessions
Contamination Frequent types Repeated doubts Ordering Aggressive or blasphemous impulses to shout an obscenity in church to hurt a loved one Sexual thoughts and imagery a recurrent pornographic image (…that violates one’s morals or runs counter to one’s sexual preferences)
DSM compulsion definition
Repetitive behaviours or mental acts the person feels driven to perform in response to an obsession, or according to rigid rules
Behaviours or mental acts aimed at preventing or reducing distress or preventing some dreaded event or situation
Not to provide pleasure and/or gratification
Behaviours are excessive or not realistically connected to what they are intended to prevent.
outline some behaviours that are compulsions
behaviours:
Hand washing Ordering Checking Cleaning Repeating Hoarding
Acts:
Counting Praying Saying words silently Thinking good thoughts to undo bad thoughts
The person with OCD feels compelled to perform acts repeatedly that often seem pointless and absurd even to them and that they in some sense don’t want to perform
Rituals in eating and dressing
Washing rituals: •Washing hands for about 20 minutes after using the toilet
•Washing hands for hours with disinfectants up to the point of bleeding
Checking: •All the lights, appliances, and locks two or three times before leaving the house
•Going back to a junction where one thinks one may have run over a pedestrian and spending hours checking for any sign of the imagined accident
what si the DSM criteria for OD

B. Obsessions or compulsions are timeconsuming (>1hr/day) or cause clinically significant distress or impairment in social, occupational, or other important areas of functioning
C. The O-C symptoms are not attributable to the physiological effects of a substance or another medical condition
D. Disturbance is not better explained by the symptoms of another mental disorder
what is an insight specifier?
With good or fair insight: The individual recognizes that obsessive-compulsive disorder beliefs are definitely or probably not true or that they may or may not be true. …many
With poor insight: The individual thinks obsessive-compulsive disorder beliefs are probably true. …some
With absent insight/delusional beliefs: The individual is completely convinced that obsessive-compulsive disorder beliefs are true. …<4%
what are the prevelence of OCD?
Usually begins in late adolescence or early adulthood
Estimated UK prevalence 1-2% of general pop.
Equally common in men and women
In childhood onset the disorder is more common in boys than in girls
At least 50% of sufferers have at least one other psychological disorder
Themes of sexuality, exactness and symmetry more common in men; contamination & cleaning more so in women
Culture may influence the themes of obsessions and compulsions.
E.g., religious obsessions and compulsions more common in cultures that emphasise the importance of religious observance
what causes OCD
Unwanted cognitive intrusions are experienced by most people.
(i.e., unpleasant thoughts, images, and impulses that intrude into consciousness)
These intrusions typically have similar contents to clinical obsessions.
BUT it is the Apprasisal or thoughts about the thought that are critical
Misappraisals are due to dysfunctional beliefs, e.g., beliefs about:
(1) inflated personal responsibility over one’s own and other’s safety.
(2) thought-action-fusion (TAF): (1) thinking about an unacceptable or disturbing event makes it more likely to happen. (2) obsessional thoughts are morally equivalent to forbidden actions.
(3) excessive concerns about the importance of controlling one’s thoughts.
The strength of such beliefs affects the risk that a person will develop obsessions and compulsions
Intrusive thought Stabbing one’s child with a carving knife +Dysfunctional belief Thinking of something = having done it=Distress
give the psyholgical studies looking into dysfunctional beliefs and OCD
Tolin et al. (2003, 2008): dysfunctional beliefs were associated with OCD symptoms in both clinical and nonclinical samples.
Abramowitz et al. (2006): A prospective study. Scores on a measure of dysfunctional beliefs predicted the later development of obsessions and compulsions.
Outline the supression argument for OCD
Distress motivates attempts at suppression
If thought suppression works, it should leave no vestige of the unwanted thought at all.
Try to pose for yourself this task: not to think of a polar bear, and you will see that the cursed thing will come to mind every minute
Wegner et al. (1987): white bear study.
Texan undergraduates.
5-minute suppression session, participants had to ring a bell each time a white bear came to mind.
PPTS thought about bear more than once/ min
what is post supression rebound
Post supression rebound :
After suppression task subjects asked to think about the white bear for 5-mins.
These subjects signaled more white bear thoughts than controls who were asked to think about a white bear from the outset.
Paradoxical rebound effect: attempts to suppress thoughts can “rebound” and result in an increased occurrence of the thoughts.
outline how thought supression is involved with OCD
Thought suppression attempts result in more rather than less intrusions.
This paradoxical effect of thought suppression may result in full blown obsessions.
There is some evidence that OCD symptoms are associated with a general failure of suppression.
Paradoxical rebound effects may be stronger for patients with OCD.
E.g., Tolin et al. (2002): Participants pressed one button for a word (e.g, “HOUSE”) and a different key for a non-word (e.g., “JWOSE”).
Words: BEAR, VINE, CURB, SCAR, GOWN Non-words: REKM, BLOY, NOFE, POSC, WATI.
“In this experiment, you will be asked to suppress all thoughts of a bear. Do not allow a thought of a bear to enter your mind, and if the thought should come into your mind, please remove it from your mind immediately. Between trials, the computer will remind you to suppress the thought. When you see this, it is very important that you suppress all thoughts of a bear.”
OCD patients showed faster responses to the word BEAR than to other words. This effect was not seen in controls.
how does distress produce compulsions?
Attempts to prevent any harmful consequences
(e.g., by avoiding knives and continually asking other people to check on the safety of the child).
Compulsive rituals develop as efforts to remove intrusions and to prevent any perceived harmful consequences.
Compulsions become persistent and excessive because they are negatively reinforced by immediate distress reduction and by the temporary removal of the unwanted thought
Compulsions also prevent people with OCD from learning that their appraisals are unrealistic
(e.g., the affected individual fails to learn that unwanted harm-related images do not lead to acts of harm).
Finally, compulsions can strengthen dysfunctional beliefs about responsibility.
The absence of the feared consequence after performing the compulsion reinforces the belief that the person is responsible for removing the threat
what is the cognitive behavioural model of OCD?
intrusive though or image –> misappraisal as important/threatening -> distress –> attempts to supress thought and consequences -> distress reduction –> maladaptive core beliefs
Outline CBT treatment for OCD
Exposure and response prevention
Expose the individual to the triggering stimuli (obsession) and block the neutralising behaviour (compulsion)
Exposure Systematic, repeated, and prolonged confrontation with stimuli that provoke anxiety and the urge to perform compulsive rituals.
Response Prevention Person refrains from performing compulsive rituals
The individual learns:
• Anxiety is temporary
• The feared catastrophic consequence never transpires
• Their interpretation of the obsession weakens
• Obsessional thoughts are harmless
give an example ofexposure hierarchy for a compulsive washer
Session 1: Walk with therapist through the building touching doorknobs, holding each for several minutes
• Session 2: Repeat above and add contact with sweat by having patient touch armpit and inside of shoe
• Session 3: Repeat above but introduce having patient touch toilet seats
• Session 4: Repeat above but introduce urine by having patient hold a paper towel dampened in her own urine
• Session 5: Repeat above but introduce fecal material by having patient hold toilet paper lightly soiled with her own fecal material
• Sessions 6-15: Daily exposure to the three most fearprovoking activities are repeated.
outline CBT effectiveness
RCTs have demonstrated that exposure and response prevention (E/RP) is more effective than other forms of psychotherapy and placebos.
Meta-analyses reveal large effect sizes.
However, E/RP provokes anxiety in patients: approx. 25% drop out of treatment.
For patients who undergo E/RP, effects often last at least 2 years.
CBT also involves challenging the moralistic thoughts and excessive sense of responsibility
