Week 7 - Theories Flashcards
What constitutes a psychological theory?
- describes behaviour
- makes predictions about future behaviours
- must have evidence to support the idea
- must be testable
Why are theories important?
- Explains why a drug is more/less addictive:
- in one society than another
- for one individual and not another
- for the same individual at one time and not another
- Make sense of similar behaviour (e.g., compulsive)
- Explains cycle of increasing dysfunctional involvement with drugs
- Must be faithful to the lived human experience
Moral model
- The ‘original’ model of addiction - temperance movement (mid 1800s)
- Addiction was viewed as a sin
- Users are characterised as ‘misfits’, ‘no-hopers’, or as objects of pity; dealers are routinely described as ‘scum’, ‘vermin’ or ‘an evil menace’.
- Punishment
- common theme is choice
What do people with substance abuse struggle with according to the moral modal?
- make poor choices
- lack will-power
- unwilling to change their own lives
Moral model concerns
- Stigmatisation
- Reluctance to reach out for help
- Decreased self-esteem
- Reinforces the tendency toward self-blame, self-hatred and a sense of extreme powerlessness.
- Work against the prospect of genuine change - diminishing motivation; avoid taking responsibility.
moral model
spiritual model
- a disconnection from God or another higher power
- to overcome addiction, the individual must first establish a deeper connection with themselves, other people, and the broader world around them
- a Higher Power, a community of other
people in recovery, and a spiritual awakening, that allow people to overcome addiction
Disease model
- Assumes that the origins of addiction lie within the individual.
- Medical viewpoint - addiction is a disease or an illness that a person has.
- Addiction - illness that results from an impairment of healthy neurochemical or behavioral processes
what does the disease model believe?
- 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.
disease model
12 step model
- AA, NA, AI-Anon
- Alcoholism is “all or nothing”. Problem or no problem.
- Alcoholics are powerless over alcohol and experiences.
- Alcoholism cannot be “cured”, only managed.
- Disease is progressive and deterioration in condition is inevitable if drinking continues.
- Support through attending groups, peer support, submitting to a higher power.
The 12-step program
- Admission
- Recognition
- Submission
- Understanding
- Confession
- Readiness
- Humility
- Reparation
- Apology
- Integrity
- Meditation
- Awakening
Advantages of 12-step program
- drug use becomes a health issue and not just a legal issue
- allows ‘addicted’ people to understand their behaviour
- offers a treatment approach (abstinence) that works for some
- removes some of the shame often felt by people affected by addiction.
Disadvantages of 12-step program
- removes responsibility from the user
- offers only one course of treatment (abstinence) which is not suitable for all people, particularly young people
- not supported by a large amount of evidence.
Treatment outcomes of 12-step program
- greater friends
- spiritual connection
- finding meaning in life
Neuroscientific/biological model
Focus is on the effects of drugs on the brain.
- Genetic characteristics
- Reward systems
- Neuro-adaption
Genetic characteristics
- 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
examples of genetic characteristics
- Evidence suggest a relationship between tobacco-smoking and genes involved in dopamine regulation (Sabol et al., 1999).
- Brain’s cannabinoid system - variants of the CNRl gene were associated with cannabis, cocaine, and heroin dependence (Comings et al., 1997)
Reward systems
- dopamine reward system
- endogenous opioid system
neuro-adaptation
- 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
Psychoanalytic theories
- 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
Psychoanalytic shared assumptions
- 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
Unconscious processes that govern the id, ego, & superego (Freudian)
- Fixated at the “oral” stage
- Id – drive reduction theory.
- Ego – “self medication”
Attachment styles (Bowlby)
- Secure
- Ambivalent-avoidant insecure
- Anxious-avoidant insecure
- Disorganised-insecure
Personality theory
- 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
personality predictors of drug use
- Behavioural disinhibition (impulsivity)
- Emotional negativity (negative mood, depressive PD)
- Sensation seeking
- Non-conformity
- Social isolation and tolerance for deviance
- Avoidance
