Q

moral model

spiritual model

A
  • a disconnection from God or another higher power

Q

what does the disease model believe?

A
  • Addiction does not exist on a continuum – present or not
  • Addicted people cannot control their intake.
  • The disease of addiction is irreversible. It cannot be cured and can only be treated by lifelong abstinence.

Q

Genetic characteristics

A
  • People may inherit an increased likelihood (vulnerability) of developing dependence on substances.
  • no single candidate genes have been discovered directly related to addiction but may involve multiple genes or incomplete expression of several major genes

Q

neuro-adaptation

A
  • Refers to changes in the brain that occur to oppose a drug’s acute actions after repeated drug administration.
  • When drugs are repeatedly administered, changes occur in the chemistry of the brain to oppose the drug’s effects.
  • When this drug use is discontinued, the adaptations are no longer opposed; the brain’s homeostasis is disrupted

Q

Psychoanalytic theories

A
  • we can link problems to our childhood and how we cope (or don’t cope) as adults
  • Basis of many counselling approaches
    which aim to gain insight into an individual’s unconscious motivations and try to enhance their self-image
  • nature and nurture
20
Q

Psychoanalytic shared assumptions

A
  • Drug use is a symptom of an underlying psychological disorder
  • Indicates severe psychopathology
  • Psychological problems are assumed to cause substance abuse, but not usually recognised as a consequence of use
  • Addiction is considered a uniform disorder
21
Q

Unconscious processes that govern the id, ego, & superego (Freudian)

A
  • Fixated at the “oral” stage
  • Id – drive reduction theory.
  • Ego – “self medication”
22
Q

Attachment styles (Bowlby)

A
  • Secure
  • Ambivalent-avoidant insecure
  • Anxious-avoidant insecure
  • Disorganised-insecure
23
Q

Personality theory

A
  • Group of distinct personality characteristics that distinguish alcoholics/drug users from other individuals
  • Predisposing factor (‘addictive personality’)
  • Limited evidence of ‘addictive personality’
  • Characteristics of personality attributed to addictive personality do not predict addiction, but rather can be the result of addiction
24
Q

personality predictors of drug use

A
  • Behavioural disinhibition (impulsivity)
  • Emotional negativity (negative mood, depressive PD)
  • Sensation seeking
  • Non-conformity
  • Social isolation and tolerance for deviance
  • Avoidance
25
Q

How does psychodynamic theory view addiction?

A

self-regulation disorder:
* inability to recognise and regulate feelings;
* inability to establish and maintain a coherent, comfortable sense of self and self-esteem
* inability to establish and maintain adequate, comforting, and comfortable relationships;
* inability to establish and maintain adequate control/regulation of behaviour, especially self-care

26
Q

Social learning models

A
  • substance use is : learned and is functional
  • based on the user’s thoughts about the substance, and what it is like to be ‘under the influence’ of the drug
  • focus on the interaction between the environment, the individual and the drug
27
Q

Key points of social learning theory

A
  • Anyone who engages in an activity that they find pleasurable is at risk of developing dependence on that activity.
  • Dependence is a learned behaviour - results from conditioning, modelling and thinking about the substance.
  • Dependence exists in degrees. The greater the dependence then the greater the negative feelings experienced in the absence of
    the activity.
  • Dependence is a normal facet of human behaviour. It only becomes a problem when the individual experiences a number of
    negative consequences as a result of their behaviour, but continues to do it anyway.
  • A sense of compulsion, of wanting to engage in a behaviour (such as drug use), but knowing that one really shouldn’t, is the hallmark of addictive behaviour.
  • Behaviours are only terminated when the individual makes the decision that the costs of continued use are vastly greater than the
    benefits.
28
Q

Social learning interventions

A
  • focus on altering the client’s
    relationship with their environment
    personal factors <–> environment <–> behaviour
    Example: Adolescents who view substance use in a positive light, whose peers use drugs, and whose parents and peers have attitudes that
    condone substance use are more likely to use substances
29
Q

Behavioural theories

A
  • Only considers observable/measurable behaviour
  • Behaviour is a consequence of learning
    four types of conditioning:
    1. Classical conditioning
    2. Operant conditioning
    3. Modelling
    4. Tension reduction
30
Q

Classical conditioning models

A

Sights, smells and sounds consistently associated with drug use elicit physiological and psychological responses that lead to drug seeking behaviour
- Conditioned stimuli (CS) – cues and triggers
- Conditioned response (CR) – physiological and
psychological responses
CS more important than CR

31
Q

Operant conditioning

A

reinforcing properties of drugs, and the
likelihood of people repeating immediately pleasurable experiences (and avoiding unpleasurable experiences)
three reinforcement types:
1. Positive reinforcement (e.g., drugs can cause
pleasurable sensations)
2. Negative reinforcement (e.g., use to remove aversive experiences)
3. Punishment

32
Q

Modelling

A
  • People learn favourable attitudes and expectation about drinking based on how the behaviour is modelled.
  • Increases the likelihood of pleasant experiences learned from others
  • Maintenance associated with past associations with drug-taking environments/situations
33
Q

Tension reduction theory

A
  1. TENSION in society
  2. Demands RELIEF
  3. PROBLEM of elimination of reduction of conditions that create tension
  4. PROBLEM of finding a mode for relief of tension
34
Q

ABC’s

A

Antecedents
- triggers
- situations
- thoughts
- feelings
Behaviour
- something the person does
Consequences
- Reinforcers – outcomes that maintain the
behaviour
- Payoffs

35
Q

Cognitive & Cognitive-behavioural theory

A
  • cognitive model
  • expectancy theory
36
Q

Cognitive model

A
  • Focuses on the thoughts/beliefs, and impact on behaviours and feelings
  • The way people interpret specific situations influences feelings, motivations and actions.
  • Layers of beliefs – core beliefs / schemas
37
Q

Layers of belief

A

Early experience –> Dysfunctional beliefs about self –> Critical incident –> Automatic negative thoughts

Symptoms:
* behavioural
* motivational
* mood
* thought
* physical

38
Q

cognitive model cont.

A
  • Conflicting beliefs (cognitive dissonance):
    Conflict between the desire to use drugs and the desire to be free of drugs e.g. “I should not use alcohol” vs “It’s OK to have a drink just this one time”
  • Leads to a cycle of behavioural, emotional and thinking
    patterns
  • Cognitive-behavioural: thoughts and behaviours are learnt and therefore can be ‘unlearnt’ (CBT)
39
Q

Third wave psychotherapies, contextual CBTs

A
  • Acceptance and Commitment Therapy (ACT)
  • Dialectical Behaviour Therapy (DBT)
  • Mindfulness-based relapse prevention
40
Q

Key difference to traditional CBT

A
  • emphasis on mindfulness and acceptance strategies to reduce the impact of internal triggers on substance use behaviour (e.g.,
    altering the context and function so cravings, distress, or thoughts of using are less likely to lead to substance use).
  • Taking a broad, functional approach to treatment, emphasising motivation and values-based strategies
  • Transdiagnostic - effectively target key psychological problems commonly comorbid with substance use including depression,
    anxiety and self-stigma
41
Q

Expectancy theory

A

Addictive behaviours chosen over other behaviours due to our expectancies.
Two specific cognitions:
- Outcome expectancy – beliefs about effects and outcomes of using
- Self efficacy – belief in ones own ability to effect change

42
Q

Motivation and change theories

A
  • ‘Transtheoretical’
  • Increase the client’s awareness of the potential problems caused, consequences experienced, and the risks faced as a result of the behaviour in question (AOD Framework 2014)
  • Clients do not necessarily enter treatment committed to action and making changes
  • Motivational interviewing (Miller) - intrinsic motivation is a necessary and sufficient factor to initiate behaviour change
43
Q

Transtheoretical approach

A

precontemplation - no intention of changing behaviour
contemplation - aware a problem exists. no commitment to action
preparation - intent upon taking action
action - active modification of behaviour
maintenance - sustained change, new behaviour replaces old
relapse - fall back into old patterns of behaviour

44
Q

family and systems theory; socio-cultural

A

Determinants of behaviour are based on an individuals role within a system

45
Q

family & systems theory

A
  • Determinants of behaviour are based on an individuals role within a system
  • Focuses on society as whole and not just on individuals
  • Many differing theories. Shared common elements:
     Boundaries
     Reciprocal causality
     Homeostasis
     Family based interventions eg ‘Stress coping’ perspective
     Importance of placing emphasis on interventions for the system e.g., family therapy/involvement of significant
    others, addressing stigma, poverty, poor housing, disadvantage etc
46
Q

society as a role in drug use

A
  • Family and other systems (e.g., peers) have role in initiating and maintaining substance use
  • The type of society in which people live has an impact on their drug use. In particular, this model makes links between inequality
    and drug use. It suggests that people who belong to groups who are culturally and socially disadvantaged are more likely to experience substance abuse problems.
  • Because this model links substance abuse to the conditions of the wider society, importance is placed on interventions on the system rather than the individual.
47
Q

Bipsychosocial theory

A

drug use is influenced by a combination of
biological, psychological, and social factors
Biology:
- physical health
- genetic vulnerability
- drug effects
Psychological:
- physical health
- coping skills
- social skills
- family relationships
- self-esteem
- mental health
Social:
- peers
- family circumstances
- family relationships
