Negative emotions subside when
Person will purge
26
Difference between anorexia and bulimia
Is body weight -Those with anorexia are underweight, people with bulimia are not underweight
27
Binge eating disorder
Objective binge eating episodes -There is no compensatory behaviour= purging after
28
People with BED experience
Distress, eat very rapidly, eat large amounts even when not hungry, eat alone because of embarrassment about the amount they are eating, feel guilty or disgusted after binge eating episodes
29
Similarities of BED, Anorexia, and Bulimia
-They still have weight and shape concerns
30
DSM-5-TR and Anorexia
1) Restriction of energy intake leading to a body weight that is less than minimally normal/expected (BMI). Significant low weight= weight less than normal 2) Intense fear of gaining weight or of becoming fat, or persistance behaviour that interferes with weight gain, even though at a significantly low weight 3) Disturbance in the way in which one's body or shape is experienced, undue influence of body weight or shape on self evaluation, or persistent lack of recognition of the seriousness of the current low body weight 4) Distortion in the experience of their body weight in self evaluation- don't understand seriousness of underweight, determines worth based on shape, etc
31
Restricting Type- DSM-5-TR
During the last 3 months, the individual has not engaged in recurrent episodes of binge eating or purging behavior (i.e., self-induced vomiting or the misuse of laxatives, diuretics, or enemas). This subtype describes presentations in which weight loss is accomplished primarily through dieting, fasting, and/or excessive exercise.
32
Binge-eating/purging Type: DSM-5-TR
During the last 3 months, the individual has engaged in recurrent episodes of binge eating or purging behavior (i.e., self-induced vomiting or the misuse of laxatives, diuretics, or enemas).
33
Bulimia- DSM-5TR
1) Recurrent episodes of binge eating: -Eating in discrete, an amount of food larger than most -Sense of lack of control over eating during the episode (feeling that one cannot stop, etc 2) Recurrent inappropriate compensatory behaviors in order to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise. 3) The binge eating and inappropriate compensatory behaviors both occur, on average, at least once a week for 3 months. 4) Self-evaluation is unduly influenced by body shape and weight. 5) The disturbance does not occur exclusively during episodes of anorexia nervosa.
34
BED criteria
-Recurrent episodes of binge eating- do not engage in compensatory behaviours -Eating very rapidly, eating until uncomfortably full -Eating large amount of food even when not hungry -Eating alone (embarrassment) -Feeling disgusted, depressed, guilty after binges -Must occur at least once per week for three months
35
Other specified feeding or eating disorder
Encompasses eating disorders of clinical severity that do not meet the specific criteria of anorexia, bulimia, or BED
36
OSFED night eating syndrome
Repeated nocturnal eating (but not binge eating
37
Unspecified feeding or eating disorder
Applies to individuals with eating disorder symptoms that causes distress and/or impairment, but do not meet criteria for any of the specified eating disorders
38
Assessments for eating disorders
Structured or semi structured interview -Eating Disorder Examination (EDE)
39
EDE
Structured clinical interview for diagnosing eating disorders -Provides numerical ratings of the frequency and severity of eating disorder symptoms
40
Eating Pathology Symptoms Inventory (EPSI)
Developed to assess eating pathology dimensionally -45 item self report inventory measures eight core yet distinct features of eating disorders (body dissatisfaction, binge eating, purging, cognitive restraint, excessive exercise, etc)
41
Assessments of Eating Disorders
-Current and past history -Interpersonal functioning and potential factors -Absence or presence of other disorders -Medical examination -Self report questionnaires
42
Physical and Psychological Complications- Anorexia
-Osteoporosis -Cardiovascular problems -Gastrointestinal -Neurological -Endocrine systems -Decrease in fertility -Amenorrhea (absence of periods) -Skin problems -Hair loss -Langugo= a fine downy hair that may grow on the body to maintain body warmth -Difficulty concentrating and irritability
43
Issues with Bulimia and Binge Eating Disorder
-Dental problems (erosion of tooth enamel)= presence of stomach acid during vomiting -Electrolyte imbalances (hypokalemia (low potassium) -Cardiovascular issues
44
Soldier assessment results
-decrease in heart rate -Increases in emotional instability (depression, etc) -Difficulty concentrating, decreased sex drive -Lethargy -Dry skin and hair loss -Increased on food= main topic of convo
45
Genetic and Biological Factors
-Relationship between serotonin= role of serotonin in feeding, satiety, mood, and impulse control -Dopaminergic dysfunction also investigated -Puberty and the body changing can also be a factor -Changs in sex hormones= estradiol in females can impact the expression of genes that affect eating disorders
46
Sociocultural Factors
-Internalization of body image ideals. Thin ideal internalization is believed to be directly associated with body dissatisfaction
47
Family Factors
-History of eating disorders were at higher risk for eating disorders -Mothers' concerns about their child's weight
48
Personality Traits
-Lower extraversion and higher perfectionism, neuroticism, negative urgency, avoidance motivation, sensitivity to social rewards, self directedness
49
Anorexia and personality
-High levels of constraint, preservation, ridgity, and low levels of novelty seeking -OCD
50
Bulimia and Personality
-High impulsivity and novelty and sensation seeking -Borderline personality disorder
51
Personality Traits that place them at risk
Negative emotionality Poor interoceptive awareness neuroticism Perfectionism Negative schemas Traumatic events
52
Integrative Models
To describe the development and maintenance of eating disorders (example risk factors and maintenance factors)
53
Risk factors
Refer to variables that occur prior to the onset of the disorder, and which predict the disorder's onset -Sociocultural variables (media exposure, internalization of the thin ideal) -Psychological factors (perfectionism, negative emotionality)
54
Maintenance factor
Is a variable that leads the symptoms to persist after the onset -Negative affect= serves as this factor because these behaviours may relieve negative emotions
55
Bulimia= Treatment
-Antidepressant medications, Fluoxetine (Prozac) -Anti-convulsant drug topiramate (Tomamax)
56
Treatment= Binge eating disorder
Antidepressant medications—including fluoxetine, fluvoxamine (Luvox), citalopram (Celexa), and sertraline (Zoloft)—have demonstrated good efficacy for BED. Sertraline appears to have particularly good results for BED.
57
Anorexia and drugs
-Attempts to treat anorexia with pharmacological agents have not been successful
58
Neurostimulation treatments
-Interventions that use energy (electricity or magnetism) to alter the functions of the nervous system -Ex: deep brain stimulation and repetitive transcranial magnetic stimulation (rTMS)
59
rTMS
-Non invasive methods that uses electromagnetic induction to impact neural activity
60
DBS
Involves the surgical implantation of electrodes into a particular brain area, which then receive electrical stimulation from a device that is implanted in the chest
61
Dysfunctional Scheme for Self Evaluation
-Life leading to dysfunctional sceme for self evaluation: over evaluation of eating, shape, and weight and their control, or over evaluation of achieving "Perfectionism" -Core low self esteem contributes to both overvaluation of eating, shame, and weight, and their control or over evaluation of achieving perfectionism
62
Binge eating and CBT
-Regular eating -Challenge dietary rules and expand the variety of foods they eat -Have less biased perceptions of their body
63
Interpersonal therapy
-the focus is on maladaptive personal relationships and ways of relating to others -Therapist identifies which problem area is relevant to the patient- grief, role transitions, etc and to work to improve the client's functioning in that area
64
Nutritional Counselling
-Restore body weight
65
family Therapy and Anorexia
Focusses on stresses within the family as a whole rather than on individuals and places responsibility for recovery on both the client and relatives
66
Family Based Therapy (FBT) aka Maudsley approach
-initial focus on the eating disorder symptoms, with parents or caregivers playing a key role in managing the patient’s eating behaviours and weight gain (where relevant) -As eating improves and weight approaches normal levels, the therapist helps the family to return control of eating to the adolescent
67
Dissonance Based Interventions
Aim to create cognitive dissonance (discrepancy between beliefs and behaviours) by helping people learn to critique the thin ideal and motivate them to reduce behaviours aimed at pursuit of this ideal
