Q

gender differences drug use disorder

A

men: drink more, more socially acceptable, don’t care as much about withdrawal

16
Q

amphetamines

A
  • inhances release of norepinephrine and dopamine
  • > blocks reuptake

-usually treated for attention problems and narcolepsy

17
Q

Nicotine

A
  • increasing blood pressure and heart rate

- withdrawal: more hungry

18
Q

caffeine

A
  • increases alertness and motor activity
  • upregulating dopamine, norepinephrine and seretonin levels
  • increases in metabolism, body temperature and blood pressure
19
Q

opioids

A
  • morphine
  • heroin
  • codeine
  • methadone
20
Q

others: designer drugs

A

-ectasy etc

21
Q

biological factors

A
  • reward pathway

- dopamine

22
Q

psychological factors

A
  • social learning -> modeling
  • cognitive theories -> people who expect alcohol to reduce their distress, have no more adaptive means of coping
  • personality: behavioral under-control -> increased risk
23
Q

sociocultural factors

A
  • substance attractive to people under chronic stress

- > living in poverty, women in abusive relationships

24
Q

biological treatments

A
  • antagonist drugs: block/change effects of addictive drug, reducing desire for it
  • acamprosate: affects glutamate and GABA receptors and can help maintain abstinence from alcohol

-antabuse: can make people feel dizzy, nauseous, blush and event faint, with just one drink

25
Q

biological treatment - methadone maintenance programs

A

…

26
Q

behavioral therapy

A

-aversion therapy: classical conditioning (give drug followed immediately by another drug that causes unpleasant physiological reactions)

-covert sensitization therapy:
imagery to create associations between thoughts of alcohol use and thoughts of highly unpleasant consequences

-contingency management programs: reinforce abstinence

27
Q

cognitive therapy

A
  • help clients learn to handle stressful situation in adaptive way
  • identify situations in which they are likely to consume + expectations that alcohol will help them cope with those situations
  • mindfullness, meditation
28
Q

Therapy : motivational interviewing

A
  • reinforce motivation to change habit/substance use
  • empathic interaction style, drawing out user’s statements of desire, ability, reasons, need and commitment to change
29
Q

relapse prevention

A
  • avoiding specific environments and people

- abstinence violation effect

30
Q

alcoholics anonymous

A

….

31
Q

mild, moderate, severe SUD

A
  • mild: 2-3 criteria
  • moderate: 4-5
  • severe: 6+
32
Q

DSM 5 - substance use disorder

A

IMPAIRED CONTROL

  1. taken in increasingly larger amounts or over longer period originally intended.
  2. craves substance.
  3. ongoing desire to cut down or control substance abuse or has made unsuccessful attempts to do so.
  4. Much time is spent obtaining, using, or recovering from substance.

SOCIAL IMPAIRMENT

  1. inability to meet responsibilities at home, work, or school.
  2. Important social, work related, or recreational activities are abandoned or cut back
  3. Ongoing substance use despite recurring social or relationship difficulties caused or made worse by effects of substance.

RISKY USE

  1. in physically dangerous situations, such as driving a car or operating machinery.
  2. Substance use continues despite awareness of ongoing physical/psychological problems that have likely arisen or been made worse by substance.

PHARMACOLOGICAL

  1. Tolerance – Need for increased amounts of substance to achieve desired effect or by diminished experience of intoxication over time with same amount.
  2. Withdrawal – Substance user experiences characteristic withdrawal syndrome of substance and/or takes same/similar substance to relieve symptoms.
33
Q

Choice model of addiction - Heyman

A
  • addiction is a voluntary act
  • immediate rewards take precedence over long-term gains
  • repeatedly choosing immediate rewards -> LT rewards will get lower value
  • does not deny biological part, but dismisses that dopamine is key neurotransmitter for motivation and directing goal-directed behavior
34
Q

Disease model of addiction - Lewis

A
  • involuntary bc it is primarily driven by cues (Classical conditioning)
  • drug taking triggers dopamine release form VTA -> increases impact on nucleus accumbens and ventral pallidum (ventral striatum)
  • striatal + orbitofrontal activity peaked right before drug use
  • brain changes -> undermining inhibitory control, judgment, appraisal
  • > harder to quit
35
Q

Disease model of addiction - Incentive- sensitization hypothesis

A
  • alteration in responsiveness of VTA
  • > dopamine release is enhanced in relation to drug and its cues
  • > decreased in relation to other stimuli
36
Q

Choice model of addiction - Intertemporal Bargaining

A
  • reward gives rise to bargaining between different ‘selves’/ ‘positios’
  • > each position takes different point in time ( present, future)
  • > addiction = consequence of poor bargaining
37
Q

Article - Alcohol-induced place conditioning in moderate social drinkers - childs - aim and methods

A
  • Testing whether non-dependent drinkers show preference for location paired with alcohol
  • test if amount of time spent in alcohol-paired location is related to subjective alcohol effects

method:
- social drinkers assigned to paired condition : ALC and noALC in separate distinct rooms
- or unpaired condition: ALC and noALC in both rooms

  • primary measure: pre- to post-test change n percentage of time spent in least preferred room
  • secondary measure: included self-reported subjective mood and drug effects
38
Q

Article - Alcohol-induced place conditioning in moderate social drinkers - childs - hypothesis

A
  • significant group difference
  • Time spent in ALC-paired room would increase among paired group individuals, but not in unpaired group
  • change in time would be related to positive pleasurable effects of alcohol
39
Q

Article - Alcohol-induced place conditioning in moderate social drinkers - childs - results

A
  • groups differed in change in percentage
  • paired group: increased 11p
  • unpaired group: -1.4p
  • Non dependent consumers of alcohol -> develop behavioral preference for locations paired with alcohol consumption
  • > more so for those who experience sedative effects from alcohol in those locations.
