EXAM Flashcards
obsession and compulsions
obsessions: intrusive thoughts that provoke distress or anxiety
compulsions: repetitive behaviours/mental acts to reduce anxiety/supress obsession. types: rituals (repetitive actions like checking, hand washing, reassurance seeking), neutralizations (brief actions to “undo” obsessive thought like thinking about being healthy, adding “not” to obsession)
OCD dsm criteria
A. presence of obsessions and/or compulsions
B. OC take 1+ hour per day or DnD
C, D. no better explantions
insight in OCD
can be added as a specifier (good/fair/poor)
good: knowing the compulsions are absurd but can’t stop
fair: knows it absurd but helps them feel sure
poor: feels like they truly did something wrong they cant remember, closer to psychosis, may not know the OC are connected
OCD brain
PFC dysfunction may lead to being overly focused on irrelevant details, problems with organizing relevant info, poor self-monitoring (forming concrete memory of doing something - made worse by repetition aka harder to remember if you did something if you keep checking), inability to change behaviour
Connected to serotonin
repeated checking leads to…
lowered memory confidence, increased doubt, more checking
OCT CBT Etiology
Catastrophic misinterpretations of harmless random thoughts leading to an attempt to suppress the thoughts (compulsions), validating the danger of the thoughts, thus making them worse
The loop is the disorder not the thoughts
Maintained by compulsions and the negative reinforcement of compulsions (they reduce anxiety so ill keep doing them)
OCD loop
trigger, intrusive thought, faulty appraisal (assigns scary meaning to thought and assumes responsibility to stopping it), anxiety, compulsion, relief, repeat
BDD dsm5
A. preoccupation with one or more “flaws” in appearance that appear slight to others
B. repetitive behaviours in response to appearance (mirror checking, reassurance seeking, comparing appearance)
C. DnD
D. Trait is not body weight
Specifier: muscle dysmorphia
Hoarding disorder DSM5
A. persistent difficulty parting with possessions regardless of value
B. Difficulty is bc they feel they need to save them and it is distressing to throw them out
C. accumulation of things in ACTIVE living areas that compromise intended use, if its cleared its by someone else
D. DnD
E,F. No better explanation
Subtype: animal hoarding
Hoarding risk factors
middle age, OCD, experienced major loss, poverty, indecisiveness, avoidance, difficulty planning and organizing, distractibility
OCD/BDD first line treatment
Exposure and response prevention and SSRIs are first-line.
Exposure causes anxiety by purposefully triggering obsessive thoughts, response prevention is not engaging w/a ritual (“surf the wave” of anxiety and watch as the wave lessens over time). Over time, extinguishes neg. reinforcement and reduces anxiety associated with the obsession (not necessarily the frequency of thoughts). Use the SUDS and exposure hierarchy.
Mindfulness approaches can be helpful for relapse prevention
hoarding treatments
CBT with motivational interviewing is first line (explore ambivalence to change and try to find reasons to want to change)
CBT explores dysfunctional beliefs about discarding stuff (usefulness, wasting, sentimental attachment, the need to remember). Use questions to evaluate the accuracy of these beliefs and offer alt options
Practice letting go of stuff, starting easy and increasing in difficulty up to sentimental items (exposure therapy basically, tolerate neg emotions and challenge beliefs)
CBT for OCD
challenge faulty appraisals (ignore content on obsessions) via thought records (what is a more realistic assessment of the situation)
Explores false sense of responsibility
via responsibility pie (lots of things could be the cause of something other than you)
Examine likelihoods of risk via continuum (holding baby without washing hands is not 0% danger but its much better than leaving the baby alone in a room)
BDD CBT
challenge body image equals real physical appearance
evaluate distorted thoughts about body and imagined consequences
Exposure therapy things therapists should do
Do exposure with them
ask intermittently their level of anxiety 1-10 (SUDs tracking)
point out the wave going up and down
dont try to relieve anxiety, point out the germs.
afterwards, make them feel proud and show them that the compulsion is not the only thing that can relieve anxiety - robs obsession of power and gives it to pt
Can do compulsion after but make sure anxiety came down already bc of time not compulsion.
SUDS
subjective units of distress scale
exposure for pedo/serial killer OCD
change baby, babysit kids, journal describing pedophila, reading pedo artiles
sign a contract with the devil “pls satan make me a killer”

PTSD treatments
exposure therapy, CBT, and medication is first line
Start with imaginal (review circumstances of event, move up to details), them in-vivo if possible (walk alone at the site of trauma)

C. Doesnt meet criteria for another disorder
D. its not normal bereavement
E. Once stress is over, symptoms don’t persist for more than an additional 6 months
*catch all, controversial
Acute stress vs adjustment disorder
AS: occurs after sudden trauma, develops quickly, more intense
AD: after significant life change (like job change, moving, etc.), develops over a span of 3 months, less intense
history of dissociative disorders
hysteria, demonic possession, freud’s “coversion” (conversion of anxiety into physical symptoms to avoid conflict/responsibility, subconscious manifesting physically)
dissociation definition
lack of integration of features like identity, memory, consciousness, sensorimotor functioning, behaviour
“fracturing of a whole”

Surroundings are experienced as dreamike, foggy, lifeless, or visually distorted
Technique to treat dissociation
Grounding. ask them to notice the colour of your eyes, what is happening in the painting, throw a pillow

Distinct personality traits definition
marked discontinuity in sense of self
alterations in affect, behaviour, consciousness, memory, perception, cognition, other sensory motor functioning
observed by others or themselves
in some cultures, characterized as possession
recovered memory therapy
roots in psychoanalysis
tries to retrieve repressed memories, more often induces false memories
Dissociative disorders trauma model
Diathesis-stress
Personality traits: high hypnotisability, fantasy proneness, openness to alterned states of consciousness
Dissociation as a defence mechanism for trauma
Dissociative disorders attachment theory
Individuals with disorganized attachement as babies are more vulnerable to develop a disorder later on
Dissociative disorders socio-cognitive model
disorders are “iatrogenic” i.e manufactured or amplified by therapy
Culture/media disproportionately affects prevalence (specifically with DID)
Somatic symptoms disorder DSM5
A. One or more somatic symptoms that are causing DnD

B. Presents to other as ill, impaired, injured
C. Evident in the absence of obvious external reward (money, not sympathy and attention)
D. not better explained by delusion or psychotic disorder
Somatic disorders etiology
Psychoanalytic (conversion of anxiety)
HPA axis
Dysfunctional beliefs about illness
Personality traits
Early life experiences
Social Learning (adopt the sick role)
early understandings of eating disorders
anorexia was introduced in DSM1 but very rare bc intentionally losing weight was much stranger at the time, no societal expectations of thinness and malnutrition was a bigger fear
Diagnostically included slow pulse, skin changes, no period
Bulimia introduced in DSM3
Treatment: force feeding
Viewed as hysteria converted into food problems like disgust, feeling full, psychosomatic stomach pain after eating
ARFID
Most common in children
Disturbances in eating (lack of interest, avoidance based on sensory characteristics, concern about aversive consequences) manifested by significant weight loss/failure to meet weight, nutritional deficiencies, dependence on supplemental eating, interference with psychosocial functioning
Not better explained by lack of food or culture
No weight concerns
Pica
Eating non food bc of cravings, to reduce nausea, they like the taste
May be due to a nutrient deficiency
Rumination disorder
Regurgitating and rechewing food
often in children
Amenorrhea
Lack of periods
Was a criteria of AN until DSM5
Anorexia nervosa DSM5
A. Restricted eating leading to significantly low weight
B. Intense fear of gaining weight OR behaviour that interferes with gaining weight DESPITE LOW WEIGHT (necessarily irrational/delusional)
C. Disturbance in the way their weight/shape is experienced (dysmorphia or general distress/dissatisfaction with body), undue influence of weight/shape on self-evaluation, or lack of recognition of the seriousness of low body weight
Restricting type: in the last 3 months, no binging-purging behaviour, only fasting
Binging-purging type: in the last 3 months, binging and purging behaviour has been present
Mild, moderate, severe, extreme based on BMI
Common characteristics of AN
Rituals associated with eating (only 1 pea very 5 mins)
Compensatory measures after eating like excessive exercise and purging
Often conflicts between parents and children, leading to secretive behaviour
Low self esteem
Hypervigilance in assessing body
Perceive their body to be bigger than it is
Binge eating disorder
A. Objective binge eating
B. 3+ of: eating too fast, until uncomfortably full, eating large amounts when not hungry, eating alone bc of embarrassment of how much their eating, feelings of disgust, depression, or guilt with themselves after a binge (5)
C. Distress
D. At least 1x a week for 3 months
E. Not compensatory or exclusively during BN or AN
Objective binges/binge eating definition for BED and BN
- Eating more than most ppl would eat within usually 2 hours
- Feeling out of control as if they cannot stop eating or control themselves
No firm threshold
Bulimia DSM 5
A. recurrent binge eating
B. Compensatory behaviours to prevent weight gain after binges like vomiting, laxatives, other meds, fasting, excessive exercise (“purging”)
C. Both binging and purging occur on average once a week for 3 months
D. Self evaluation is unduly influenced by weight/shape
E. Does not exclusively occur with AN (AN with binge purge subtype trumps BN)
AN vs BN
AN: Low body weight, more restrictive behaviours, purging is more associated with intentional weight loss not compensatory
BN: weight is usually maintained, binging and purging are more linked, closer in time, binges often larger (potentially more objective binges than AN)
Disorders that were previously called EDNOS
Atypical AN: all criteria met but weight in normal range
BN or BED with low frequency or limited duration
Purging disorder: purging related to weight but no binge and doesn’t meet AN criteria
Night eating syndrome
Also, other unspecified
Kleine levin symptom
hypercomnia with complusive eating
may lead to a misdiagnosis of an eating disorder
Why do ppl argue all EDs should be treated as one continuum of disorders?
Around 50% of ppl with AN will also develop BN at some point
Ppl often switch bw categories which decreases utility of diagnosis (AN usually in teens, BN in early adulthood, BED in adulthood)
Dimensions/alt models to consider for eating disorders
Age, Weight (AN<BN<BED), anxiety for AN, depression for BN/BED, different physiological symptoms for each
Incidence/prevalence of EDs
Vast majority women, huge spike at 15-19
Gay men more concerned with bein overweight than straight men
ED prognosis
Highest mortality rate, 50% ish treatment response, high relapse rate, often have another ED after, sometimes treatment can be too late
Refeeding syndrome
Lethal syndrome when nutrition is corrected too quickly
Physical consequences of EDs
osteoporosis, heart problems, fertility ssues, lethargy, hair loss, heightened sensitivity to cold, lanugo (peach fuzz to maintain warmth), amenorrhea, dental problems, Russels sign (scabs on knuckles bc of purging)
Brain EDs
Reduced serotonin density
Gender differences may be due to difference in the serotonin system - women more susceptible to dysregulated serotonin, dieting may alter serotonin in women more than men
Sociocultural factors for EDs
Internalized media ideals of thinness is believed to be a causal risk factor
Average weight is increasing in north America, discrepancy leads to increased guilt, shame, dieting, body dissatisfaction
“fitness” online
Weight concerns are culturally bound but food refusal/AN isn’t
BN IS culturally bound
Family factors for EDs
mothers who diet/have weight concerns make daughters who diet/have weight concerns
Parents who are critical and emphasize weight/appearance cause daughters with worse ED outcomes
- daughters perceive a lack of care from mothers
Personality/individual differences in EDs
Associated with AN/BN: perfectionism, obsessiveness, compliance, alexithymia (lack of emotional awareness), negative view of self
Associated with BN: impulsivity
Other EDs: low self esteem, depressive affect, poor body image, dieting, excessive exercise
More BPD/OCPD symptoms in EDs
Maturation factors of EDs
In puberty, womens bodies alter in ways incongruent with societal expectations (gain weight) while men’s alter congruently (gain muscle)
More weight leads to more body dissatisfaction
Puberty increases womens awareness of sex roles, sexuality, media, etc. causes more stress
