Theories of Addiction (5)
The moral model (A disorder of choice)
Biological theory
Psychological theory
Sociological theory
Biopsychosocial model/Public health model
3 aspects of the moral model
Personal Choice
Values
Responsibility
Explains addiction as a consequence of personal choice
Places full responsibility on the users
Addictive behavior is influenced by preexisting values. Thus society should attempt to instill values that are incompatible with addiction and substance abusing behaviors
The moral model
Addiction counselors may carry internalized biases that reflect moral model attitudes and should work to increase their awareness so that they do not influence their work with clients.
Whereas public sensitivity to the struggles of addicted people has increased, many challenges and barriers continue to prevent some from accessing needed treatment
Stigma
Biological theories talk about…
Certain biological traits (inherited or acquired) may increase the likelihood of eventual drug abuse or addiction, particularly in the presence of other external influences
- Biological traits (inherited/acquired)
- A Brain Disease Model of Addiction
- Self-medicating (Biological/Psychological)
- The factors of gender, race, and age
Biological Theories
Biological Traits
Inherited
-Reward deficiency syndrome
-Genetic factor
Acquired (Neuroadaptation)
-Frequent and chronic use
Addiction is a brain disease
There is convincing evidence that drugs of abuse act directly on brain mechanisms responsible for reward and punishment
Drugs are usurping brain circuits and motivational priorities
Addiction changes brain circuits
-Reward/saliency
-Motivational/drive
-Memory/learning
-Inhibitory/control
all is explained under the…
Addiction is a brain disease
Four circuits that are involved in addiction
-Reward: Located in the nucleus accubens (NAc) and the ventral pallidum
-Motivation/Drive: Located in the orbitofrontal cortex (OFC)
-Memory and Learning: Located in the amygdala and the hippocampus
-Control: Located in the prefrontal cortex and the anterior cingulate gyrus (CG)
-Tolerance
-Withdrawal
-Blackout
-Craving/Urge
-Impulsivity
-Compulsivity
-Habit
Are explained by the
Addiction is a brain disease
Gender factor
Women have a higher BAC than men when a comparable amount of alcohol is consumed:
-Women weigh less than men
-Women have more fat and less water in their bodies
-Women metabolize less alcohol in their stomach and esophagus
In women, the liver is more prone to the toxic effects of chronic alcohol use than in men (Liver injury progresses more rapidly over a shorter period of time and with less alcohol consumed and/or alcoholic liver cirrhosis is more likely to develop and more likely to cause death.)
It is an explanation related to…
Gender factor
Race factor
The chemical breakdown of alcohol
Alcohol Dehydrogenase (ADH) to Aldehyde dehydrogenase (ALDH)
Alcohol —– Acetaldehyde —– Acetate
Age factor
Older people have a higher BAC than younger people when a comparable amount of alcohol is consumed.
-Older people metabolize alcohol more slowly than younger people. (also “increased brain susceptibility to the depressant effects” of alcohol and “decreased percentages of body water.”
-Alcohol-drug interaction effect
Gene-Environment Interactions
-Genetic effects on behavior occur because they affect an individual’s susceptibility to adverse environments
-Adverse environments, such as negative or inadequate parenting, may create a risk, depending on genetic susceptibility factors
Psychological Theories
- Social Learning Theory
- Co-occurring Disorders (COD)
- Adverse Childhood Experiences (ACEs)
- Sense of Well-being (love, worth,
relatedness, spirituality, etc.)
Theory that states we learn…
by observing others.
by modeling or imitation of significant others (indirect learning).
by the formation of conditioned responses (e.g., positive or negative reinforcement, punishment)(direct learning).
Social Learning Theory (Bandura)
Co-occurring Disorders (COD)
Although the field has well recognized the existence of the co-occurring disorder of addiction and other mental disorders, knowledge regarding its underling mechanisms and treatment is still very limited.
(a) The two co-occur not necessarily because one causes the other, but because they both share similar risk factors (e.g., trauma, genetic vulnerability, stress)
(b) The two may share similar symptoms and, therefore, are wrongly diagnosed as COD
(c) Addiction is secondary to a psychiatric disorder (self-medication).
(d) Psychopathology or a psychiatric disorder is secondary to addiction (a psychiatric disorder is induced by the pharmacologic or psychological effects of alcohol or drugs).
(e) The “hybrid model”
An initially secondary disorder may later become a primary disorder.
Theories explaining COD
Self-medication (COD):
Biological/Psychological Theories
Self-medicating a preexisting disorder
(physical [pain, sleep disturbance]or
psychological [anxiety, depression, trauma])
Psychopathology or a Psychiatric Disorder is Secondary to Addiction (COD)
A long-term six-time wave study: chronic concurrent use of cigarette, alcohol, and marijuana was related to a greater likelihood of occurrence of Antisocial Personality Disorder, Major Depressive Disorder, and Generalized Anxiety Disorder later in adulthood.
Caspi and colleagues: adolescent-onset cannabis use may trigger adult schizophreniform disorder if the person possesses certain genes.
Personality disorders
Antisocial personality disorder
Borderline personality disorder
The prevalence rate of antisocial personality disorder (ASPD) is about 3-4% in the general population; the rate is approximately 40-50% among the drug treatment study samples.
About 90% of people with a dx of ASPD have coexistent substance use disorders.
That is an explanation of the…
