Unit
- Addiction definition: a chronic, relapsing brain disorder characterized by compulsive substance seeking and use despite adverse consequences. It is recognized as a medical condition, not a moral failing, and involves changes in brain reward circuits.
- Substance abuse vs. dependence: abuse refers to recurrent use leading to impairment or distress, while dependence involves tolerance, withdrawal, and loss of control. The DSM-5 now uses a unified severity scale for substance use disorders.
- Epidemiology of substance use: approximately 1 in 10 adults in the U.S. meet criteria for a substance use disorder in their lifetime. Common substances include alcohol, opioids, stimulants, and cannabis, with varying prevalence across demographics.
- Stigma and its impact: stigma deters individuals from seeking help and can worsen outcomes. Language matters: use person-first language like "person with a substance use disorder" to reduce shame and promote treatment engagement.
- Biopsychosocial model: addiction arises from interplay of biological predispositions, psychological factors (trauma, mental health), and social environment (peer pressure, socioeconomic status). Effective treatment addresses all three domains.
- Disease model of addiction: this model posits that addiction is a brain disease with genetic and neurobiological underpinnings. It reduces blame and supports medical treatment, though some critics argue it overlooks personal responsibility.
- Recovery capital: the sum of resources (personal, social, community) that individuals can draw upon to initiate and sustain recovery. Building recovery capital is a key goal of treatment planning.
- Prevention principles: evidence-based prevention programs target risk factors (e.g., early aggression, lack of parental monitoring) and enhance protective factors (e.g., self-control, strong family bonds). Universal, selective, and indicated strategies are used.
- Neurobiology of addiction: chronic substance use alters brain circuitry involved in reward, motivation, and self-control. Dopamine pathways are dysregulated, leading to enhanced salience of drug cues and diminished response to natural rewards. These changes persist long after cessation, contributing to high relapse rates.
- Stages of change model: the transtheoretical model describes five stages precontemplation, contemplation, preparation, action, and maintenance. Counselors assess the client's stage and apply stage-specific strategies, such as consciousness raising in contemplation and behavioral reinforcement in action. Motivational interviewing is key to moving clients forward.
- Harm reduction approaches: these strategies aim to minimize negative consequences of substance use without requiring abstinence. Examples include needle exchange programs, naloxone distribution, and safe consumption sites. Harm reduction is often integrated into treatment as an engagement tool for reluctant clients, building trust and reducing deaths.
- Evidence based treatment modalities: cognitive behavioral therapy helps clients identify and change maladaptive thought patterns related to substance use. Contingency management uses incentives to reinforce abstinence, while community reinforcement approach builds sober social networks. Twelve step facilitation connects clients to mutual support groups like Alcoholics Anonymous.
- Medication assisted treatment: FDA approved medications like methadone, buprenorphine, and naltrexone are effective for opioid use disorder. Acamprosate and disulfiram are used for alcohol use disorder. These medications are most effective when combined with behavioral therapy and counseling, and must be prescribed by qualified healthcare providers.
