Week 11: Eating disorders and substance-related disorders Flashcards
1
Q
According to the DSM-5 (APA, 2013), eating disorders are characterized by

a persistent disturbance in eating behavior
2
Q
DSM-5 Criteria for. . . Anorexia Nervosa
A
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.
3
Q
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

4
Q
There are two types of anorexia nervosa:
A
the restricting type and

5
Q
Binge eating:

6
Q
purge
A
Remove the food they have eaten from their bodies (self-induced vomiting or misuse of laxatives, diuretics, and enemas)
7
Q

9
Q
DSM-5 Criteria for. . . Bulimia Nervosa
A
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.

- Eating much more rapidly than normal.
- Eating until feeling uncomfortably full.
- Eating large amounts of food when not feeling physically hungry.

- 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.

36
Substance dependence includes more severe forms of substance use disorders and usually involves

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.

center of psychoactive drug activation in the brain.
52
Central to the neurochemical process underlying addiction is the role the drug plays in activating the “_______.”

parent
54

57
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...

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,”

third or fourth
66
The dopamine theory of addiction suggests that addiction is...
the result of a dysfunction of the dopamine reward pathway
67
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
68
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
