Part One: Addiction as a Chronic Brain Disease
Addiction = Brain Disease Addiction is a brain disease that is chronic and relapsing in nature. 4

IOM Quality Chasm Recommendations “Substance use disorder treatment should move toward building its standards of care, performance measurement and quality, information and cost measures upon a chronic illness model rather than the current, acute illness-based, fragmented and deficient system of health care.”

NQF Recommendations “Patients treated for Substance Use Disorders (SUD) should be engaged in long-term, ongoing managementof their care. Primary medical care providers should support and monitor ongoing recovery in collaboration with the specialty provider who is managing their SUD.”

Lessons from Chronic Illness • Medications relieve symptoms but…. behavioral change is necessary for sustained benefit • Treatment effects usually don’t last very long after treatment stops.
Lessons from Chronic Illness • Patients who are not insome form of treatment or monitoringare at elevated risk for relapse. In addiction this could include monitoring or AA
Summary • Drugs affect the brain in ways that are long term but reversible. • These brain changes profoundly influence cognition, emotions and behavior. • There are multiple forms of treatment that can be effective in treating addicted individuals. • Addiction and many psychiatric illnesses are chronic illnesses, and, like other chronic disorders, require continuous ongoing (not episodic) treatment and support.
Part Two: Evidence Based Practices
What are Evidence Based Practices? Interventions that show consistent scientific evidence of being related to preferred client outcomes. 26
Evidence Based Practices Standards of Care are Changing It is abundantly clear that not all treatment works, some types show evidence of being more effective than others >1000 clinical trials published in Addiction Cities, states and other funding sources are increasingly demanding the use of EBPs Closer integration of behavior health with healthcare will apply same standards 27 What Defines “Evidence Based Practices” and What Does it Mean to Implement EBT? NIDA Blending Meeting,? November 2006
Principles of Effective Treatment 1. No single treatment is appropriate for all 2. Treatment needs to be readily available 3. Effective treatment attends to the multiple needs of the individual 4. Treatment plans must be assessed and modified continually to meet changing needs 5. Remaining in treatment for an adequate period of time is critical for treatment effectiveness 28 - NIDA (1999) Principles of Drug Addiction Treatment
Principles of Effective Treatment 6. Counseling and other behavioral therapies are critical components of effective treatment 7. Medications are an important element of treatment for many patients 8. Co-existing disorders should be treated in an integrated way 9. Medical detox is only the first stage of treatment 10. Treatment does not need to be voluntary to be effective 29 - NIDA (1999) Principles of Drug Addiction Treatment
Principles of Effective Treatment 11. Possible drug use during treatment must be monitored continuously 12. Treatment programs should assess for HIV/AIDS, Hepatitis B & C, Tuberculosis and other infectious diseases and help clients modify at-risk behaviors 13. Recovery can be a long-term process and frequently requires multiple episodes of treatment 30 - NIDA (1999) Principles of Drug Addiction Treatment

Part 3: Cognitive Behavioral Therapy (CBT) & Relapse Prevention StrategiesOne Example of an Evidence Based Practice 32
What is CBT and how is it used in addiction treatment? CBT is a form of “talk therapy” that is used to teach, encourage, and support individuals to reduce / stop their harmful drug use. CBT provides skills that are valuable in assisting people in gaining initial abstinence from drugs (or in reducing their drug use). CBT also provides skills to help people sustain abstinence (relapse prevention) 33
What is relapse prevention (RP)? RP is a cognitive-behavioral treatment (CBT) with a focus on the maintenance stage of addictive behaviour change that has two main goals: To prevent the occurrence of initial lapses after a commitment to change has been made and To prevent any lapse that does occur fromescalating into a full-blow relapse Because of the common elements of RP and CBT, we will refer to all of the material in this training module as CBT 34
Foundation of CBT: Social Learning Theory Cognitive behavioral therapy (CBT) Provides critical concepts of addiction and how to not use drugs Emphasizes the development of new skills Involves the mastery of skills through practice 35
Why is CBT useful? (1) CBT is a counseling-teaching approach well-suited to the resource capabilities of most clinical programs CBT has been extensively evaluated in rigorous clinical trials and has solid empirical support CBT is structured, goal-oriented, and focused on the immediate problems faced by substance abusers entering treatment who are struggling to control their use 36
Why is CBT useful? (2) CBT is a flexible, individualized approach that can be adapted to a wide range of clients as well as a variety of settings (inpatient, outpatient) and formats (group, individual) CBT is compatible with a range of other treatments the client may receive, such as pharmacotherapy 37
Important concepts in CBT (1) In the early stages of CBT treatment, strategies stress behavioral change. Strategies include: planning time to engage in non-drug related behaviour avoiding or leaving a drug-use situation. 38
Important concepts in CBT (2) CBT attempts to help clients: Follow a planned schedule of low-risk activities Recognize drug use (high-risk) situations and avoid these situations Cope more effectively with a range of problems and problematic behaviors associated with using 39
Important concepts in CBT (3) As CBT treatment continues into later phases of recovery, more emphasis is given to the “cognitive” part of CBT. This includes: Teaching clients knowledge about addiction Teaching clients about conditioning, triggers, and craving Teaching clients cognitive skills (“thought stopping” and “urge surfing”) Focusing on relapse prevention 40
Foundations of CBT The learning and conditioning principles involved in CBT are: Classical conditioning Operant conditioning Modelling 41
Classical conditioning: Addiction Repeated pairings of particular events, emotional states, or cues with substance use can produce craving for that substance Over time, drug or alcohol use is paired with cues such as money, paraphernalia, particular places, people, time of day, emotions Eventually, exposure to cues alone produces drug or alcohol cravings or urges that are often followed by substance abuse 42
Classical conditioning: Application to CBT techniques Understand and identify “triggers” (conditioned cues) Understand how and why “drug craving” occurs Learn strategies to avoid exposure to triggers Cope with craving to reduce / eliminate conditioned craving over time 43
Operant conditioning: Addiction Drug use is a behavior that is reinforced by the positive reinforcement that occurs from the pharmacologic properties of the drug. Once a person is addicted, drug use is reinforced by the negative reinforcement of removing or avoiding painful withdrawal symptoms. 44
Operant conditions (1) Positive reinforcement strengthens a particular behaviour (e.g., pleasurable effects from the pharmacology of the drug; peer acceptance) Punishmentis a negative condition that decreases the occurrence of a particular behavior (e.g., If you sell drugs, you will go to jail. If you take too large a dose of drugs, you can overdose.) 45
Operant conditions (2) Negative reinforcementoccurs when a particular behavior becomes stronger by avoiding or stopping a negative condition (e.g., If you are having unpleasant withdrawal symptoms, you can reduce them by taking drugs.). 46
Operant conditioning: Application to CBT techniques Functional Analysis – identify high-risk situations and determine reinforcers Examine long- and short-term consequences of drug use to reinforce resolve to be abstinent Schedule time and receive praise Develop meaningful alternative reinforcers to drug use 47
Modeling: Definition Modeling: To imitate someone or to follow the example of someone. In behavioral psychology terms, modeling is a process in which one person observes the behavior of another person and subsequently copies the behavior. 48
Basis of substance use disorders: Modeling When applied to drug addiction, modeling is a major factor in the initiation of drug use. For example, young children experiment with cigarettes almost entirely because they are modeling adult behavior. During adolescence, modeling is often the major element in how peer drug use can promote initiation into drug experimentation. 49
Modeling: Application to CBT techniques Client learns new behaviors through role-plays Drug refusal skills Watching clinician model new strategies Practicing those strategies Observe how I say “NO!” NO thanks, I do not smoke 50
