Session Seventeen (Addiction) Flashcards
What are some crucial facts to remember about an addiction presentation?
- Addiction exists at every strata of society
- The causes/ responses/ effects/ appearance of addiction are different at every strata
- Addiction never exists in isolation, plethora of surrounding factors
What terms are used clinically to speak about addiction?
- Clinically, we use dependence or addiction disorders more
- Addiction is not a clinical term
- Difficult to define
What methods are used to identify individuals with dependency issues?
- Self report measures (but naturally have issues around under-reporting)
- Biomarkers can be used e.g. urine dip, breathalysers, hair sample, blood (N.B. give an idea of drug USE but can’t tell us about drug DEPENDENCE, which is a significantly more subjective term
Best method = Clinical assessment using structured diagnostic interviews
Outline the DSM-5 ICD-10 features of addiction disorders?
- Physical symptoms (e.g. tolerance, withdrawal) +
- Psychological symptoms (e.g. loss of control, craving, compulsion to use, neglect of other areas of life, unsuccessful attempts to quit, problems in social/familial/work life
Also describe:
- Chronic and Relapsing nature of the condition
- Spectrum of addiction (risky use, harmful use, abuse, dependence)
- CRUCIALLY: They describe both chemical addictions such as coke, alcohol, opioids AND behavioural addictions
Give 3 examples of behavioural addictions recognised by ICD-11?
- Gambling
- Compulsive Sexual Behaviour
- Internet Gaming Disorder
(DSM-5 only recognises gambling)
Outside of those officially recognised in ICD, state some proposed behavioural addiction disorders?
- Workaholism
- Excessive exercise
- Compulsive shopping
- Orthorexia (healthy eating)
- Kleptomania
- Trichotillomania
- Social media?
Why is it difficult to accurately portray prevalence of addiction disorders?
- For many substances (alcohol, tobacco, opioid painkillers) the line between normal use and addiction is very thin
- Almost all people under-report
How do men and women differ in terms of substance consumption?
- Women consume less than men of almost all potentially addictive drugs generally
- Therefore threshold for addiction is lower
HOWEVER:
- The reverse is probably true for Painkillers and Benzos
- Female addict consumes more than Male addict
Summarise the various theories of addiction, as described by West and Hardy, 2006?
Addiction = a rational choice:
- Self-medication model
- Becker and Murphy’s Theory of rational addiction
Addiction = an irrational choice:
- Expectancy theories
- Skog’s Choice theory
- Gateway drug theory
- Cognitive bias theory
- Behavioural economics theory
Addiction = a disorder of impulse and/or self-control:
- Addictive personality theory
- Self-regulation theory
- Cognitive model of drug urges
- Self-efficacy theory
Addiction = a learning disorder:
- Classical or Operant conditioning
- SLT
- Dopamine reward theory
What is the disease model of addiction?
Addiction = a disease that afflicts people, same as any other. Started with AA and alcoholism
Pros:
- Can be extremely beneficial in helping people conceptualise and overcome their addiction, reduces stigma.
- Biological, genetic factors support
- Comes with physical symptoms (addiction, withdrawal)
- Comorbidity with mental health problems supports conceptualisation as a disease
Outline the 4 Biological risk factors associated with alcoholism?
Genes:
- Women and men heritability equal, around 50%
- 100 genes gave been implicated, small effect sizes, none necessary or sufficient.
Sex Hormones:
- Mainly affecting women
- Oestrogen increases drug seeking behaviour
- Progesterone reduces it
- Therefore differences in addiction behaviour depending on point in menstrual cycle
Metabolism:
- Women’s alcohol metabolism less efficient
- Differences in cannabis metabolism
- COCP increases metabolism of tobacco
Neuroscience:
- Becker et al, 2012
- Sex differences in brain function might explain different pathways to addiction
- Men appear to take drugs for euphoric effects
- Women take drugs for dysphoric effect
Is there such a thing as an addictive personality?
Not really.
The model of certain people being massively prone to addiction has been widely disproven, however it remains true that certain personality TRAITS e.g. Impulsivity are associated with addiction
How does the learning model suggest addiction develops?
Addiction = a collection of learned behaviour patters, which once started are extremely difficult to break out of.
E.g. its Friday, therefore I must drink
Give some psych risk factors for addiction?
- Depression
- Anxiety
- Adverse life events
- Suicidal ideation
- Eating disorders
- PTSD
- Psychosis
- Personality disorders (ASBD, BPD)
What issue is there when thinking about psych risk factors for addiction?
Cause and effect, impossible to tell which of addiction and mental health problems came first.
- Many people with mental health issues self-medicate with drugs
- Drugs worsen and create mental health issues
- Also interact with anti-depressants
- Drugs lead to unsafe situations, which lead to adverse life events, worsen mental health
- Perhaps one common factor underlines both
Name some social factors that affect addiction behaviour?
- Deprivation
- Life events
- Divorce, seperation
- Childhood abuse
- Domestic violence
- Norms
- Stigma
- Price
- Availability
