Week 11: Eating disorders and substance-related disorders Flashcards
According to the DSM-5 (APA, 2013), eating disorders are characterized by
a persistent disturbance in eating behavior
DSM-5 Criteria for. . . Anorexia Nervosa
A. Restriction of energy intake relative to requirements, leading to a significantly low body weight in the context of age, sex, developmental trajectory, and physical health. Significantly low weight is defined as a weight that is less than minimally normal or, for children and adolescents, less than that min-imally expected.
B. Intense fear of gaining weight or of becoming fat, or persis-tent behavior that interferes with weight gain, even though at a significantly low weight.
C. Disturbance in the way in which one’s body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or persistent lack of recognition of the seri-ousness of the current low body weight.
An important change from DSM-IV to DSM-5 is that in DSM-5 ______ is no longer required for a person to be given the diagnosis
amenorrhea (cessation of menstruation)
There are two types of anorexia nervosa:
the restricting type and
the binge-eating/purging type
Binge eating:
out-of-control consumption of an amount of food that is far greater than what most people would eat in the same amount of time and under the same circumstances
purge
Remove the food they have eaten from their bodies (self-induced vomiting or misuse of laxatives, diuretics, and enemas)
___ percent of ballet students suffer from an eating disorder
20
Bulimia nervosa is characterized by…
uncontrollable binge eating and efforts to prevent resulting weight gain by using inappropriate behaviors such as self-induced vomiting and excessive exercise
DSM-5 Criteria for. . . Bulimia Nervosa
A. Recurrent episodes of binge eating. An episode of binge eat-ing is characterized by both of the following:
- Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most individuals would eat in a similar period of time under similar circumstances.
- A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).
B. 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.
C. The binge eating and inappropriate compensatory behaviors both occur, on average, at least once a week for 3 months.
D. Self-evaluation is unduly influenced by body shape and weight.
E. The disturbance does not occur exclusively during episodes of anorexia nervosa.
The difference between a person with bulimia nervosa and a person with the binge-eating/purging type of anorexia nervosa is ____.
weight.
Binge-eating disorder (BED). BED has some clinical features in common with bulimia nervosa, except that
No compensatory behaviour follows the binge, and much less dietary restraint in BED.
DSM-5 Criteria for. . . Binge-Eating Disorder
A. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:
- Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most people would eat in a similar period of time under similar circumstances.
- A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).
B. The binge-eating episodes are associated with three (or more) of the following:
- Eating much more rapidly than normal.
- Eating until feeling uncomfortably full.
- Eating large amounts of food when not feeling physically hungry.
- Eating alone because of feeling embarrassed by how much one is eating.
- Feeling disgusted with oneself, depressed, or very guilty afterward.
C. Marked distress regarding binge eating is present.
D. The binge eating occurs, on average, at least once a week for 3 months.
E. The binge eating is not associated with the recurrent use of inappropriate compensatory behavior as in bulimia nervosa and does not occur exclusively during the course of bulimia nervosa or anorexia nervosa.

Addictive behavior is based on
the pathological need for a substance
Substance abuse generally involves an excessive use of a substance resulting in
(1) potentially hazardous behavior such as driving while intoxicated or
(2) continued use despite a persistent social, psychological, occupational, or health problem
Substance dependence includes more severe forms of substance use disorders and usually involves
a marked physiological need for increasing amounts of a substance to achieve the desired effects. Dependence in these disorders means that an individual will show a tolerance for a drug and/or experience withdrawal symptoms when the drug is unavailable
Tolerance
the need for increased amounts of a substance to achieve the desired effects—results from biochemical changes in the body that affect the rate of metabolism and elimination of the substance from the body.
Withdrawal refers to

Two important factors for addiction to a substance:
The first is the ability of most, if not all, addictive substances to activate areas of the brain that produce intrinsic pleasure and sometimes immediate, powerful reward
The second factor involves the person’s biological makeup, or constitution, including his or her genetic inheritance and the environmental influences (learning factors) that enter into the need to seek mind-altering substances to an increasing degree as use continues.
mesocorticolimbic dopamine pathway (MCLP) is the…
center of psychoactive drug activation in the brain.
Central to the neurochemical process underlying addiction is the role the drug plays in activating the “_______.”
pleasure pathway
for males, having one alcoholic X increased the rate of alcohol use disorder from 12.4 percent to 29.5 percent and having two such X increased the rate to 41.2 percent
For females with no X with alcohol use disorder, the rate was 5.0 percent; for those with one such parent, the rate was 9.5 percent; and for those with two X with alcohol use disorder, it was 25.0 percent
parent
children of parents whose parents had alcohol use disorder were nearly ____ as likely to have alcohol problems by their late 20s
twice
Specifically, alcohol-abusing parents are less likely to keep track of what their children are doing, and this lack of monitoring often leads to the adolescents’ affiliation with drug-using peers

stress and negative
physical abuse
child sexual abuse
Acohol abuse treatments
Antabuse
Treatment of withdrawal symptoms (Valium, benzo, diaz)
family counseling
community resources related to employment and other aspects of a person’s social readjustment (group therapy, environmental intervention, BT, AA, family groups, CBT)
Motivational interviewing (MI) is a brief intervention that was designed to be a major departure from earlier confrontational approaches in which a clinician suggested that the drinker stop consuming so much alcohol. in MI the clinician guides the patient through a…
collaborative conversation in which the patient articulates the pros and cons of drinking and ultimately makes a decision about whether she or he is motivated to change
A great strength of ___ is that it can be administered in one brief (35-minute) session and still have positive effects.
MI
A recent study found that relapse prevention (CBT) treatment worked most effectively when…
family members were involved in the treatment
2 Relapse related behaviours
“indulgent behaviors” based on an individual’s learning history. When an individual is abstinent or has an addiction under control, she or he gains a sense of personal control over the indulgent behavior. The longer the person is able to maintain this control, the greater the sense of achieve-ment—the self-efficacy or confidence—and the greater the chance that she or he will be able to cope with the addiction and maintain control
“abstinence violation effect,”
In relapse prevention treatment, clients are taught to
recognize the apparently irrelevant decisions that serve as early warning signals of the possibility of relapse.
Following alcohol, the psychoactive drugs most commonly associated with abuse and dependence in our society appear to be

third or fourth
The dopamine theory of addiction suggests that addiction is…
the result of a dysfunction of the dopamine reward pathway
The reward deficiency syndrome hypothesis suggests that addiction is much more likely to occur in individuals who
have genetic deviations in components of the reward pathway, which leads them to be less satisfied by natural rewards
there is not a simple, single “pleasure pathway” in the brain. For instance, although dopaminergic pathways play a primary role in the “wanting” or anticipation of reward, it is the _____ system that seems to play a primary role in the “liking” or consumption of rewarding stimuli
