MODELS OF ADDICTION: A SUMMARY • Moral / Temperance Model Addiction as Sin or Crime • Personal Irresponsibility • Disease Model Genetic and Biological Factors ** • 12-Step Framework; Abstinence • Education as Treatment • Behavioral Conditioning and Reinforcement • Cognitive-Behavioral and Drug Expectancies; REBT • Social Learning Models Cognitive Therapy; Modeling • Relapse Prevention
Behavioral Models Classical conditioning vs. Operant learning Initiation of substance use Primary classes of reinforcers Behavioral tolerance
Rats: heroin tolerant Received injection of heroin 15 mg/kg in familiar environment Overdose rate: 32% Rats: heroin tolerant Received injection of heroin 15 mg/kg in unfamiliar environment Overdose rate: 64% Control rats: No heroin tolerance Received injection of heroin 15 mg/kg for first time Overdose rate: 96% To some degree, drug tolerance is associated with environmental factors. Tolerance may disappear or decrease if a drug is used in an unfamiliar environment. A diagram of Siegel’s rat experiment
Behavioral Models Contingency contracting (begins with A-B-C) CRA Outpt. TX for cocaine (Higgins) Token economies in residential settings Reciprocity contracting(e.g., Antabuse contract)
Social-Cognitive Models SLT’s Reciprocal Determinism: B-P-E Modeling Self-efficacy(outcome & efficacy expectations) Sources of self-efficacy Relapse Prevention a. Addressing ambivalence b. Reduce drug availability - physical vs. psychological availability - identify triggers and high risk situations (e.g., conditioned cues) - avoiding wrong people, places, situations - lifestyle & relationship changes which support recovery - money/cash - drinking, other drugs - need for mood monitoring; craving monitoring
Relapse Prevention (con’t) c. Coping with High Risk Situations - social skills, assertiveness training - drink refusal skills - urge surfing d. Vigilance through knowledge about thinking -> feeling -> behavior chain (REBT) - apparently irrelevant decisions (AIDS) - abstinence violation effect (AVE) - lapse vs relapse - use as a learning opportunity, not permission to use. Goal not to catastrophize the lapse or induce shame, but to prevent more use
Example: Treatmentfor Cocaine Dependence A. Drug TX B. Psychological TX Community reinforcement Payment for abstinence Relapse prevention (triggers, cravings…) Lifestyle modification Self-help Groups (CA - cocaine anonymous)
