Contingency management (CM) is the application of the three-term contingency (or operant conditioning), which uses stimulus control and consequences to change behavior. CM originally derived from the science of applied behavior analysis (ABA), but it is sometimes implemented from a cognitive-behavioral therapy (CBT) framework as well.
Incentive-based contingency management is well-established when used as a clinical behavior analysis (CBA) treatment for substance use disorders, which entails that patients earn money (vouchers) or other incentives (i.e., prizes) as a reward to reinforce drug abstinence (and, less often, punishment if they fail to adhere to program rules and regulations or their treatment plan). Another popular approach based on CM for alcoholism is the community reinforcement approach and family training (CRAFT) model, which uses self-management and shaping techniques.
By most evaluations, its procedures produce one of the largest effect sizes out of all mental health and educational interventions. [1]
One form of contingency management is the token economy system. [2] Token systems can be used in an individual or group format. [3] Token systems are successful with a diverse array of populations including those suffering from addiction, [4] those with special needs, [5] and those experiencing delinquency. [6] However, recent research questions the use of token systems with very young children. [7] The exception to the last would be the treatment of stuttering. [8] The goal of such systems is to gradually thin out and to help the person begin to access the natural community of reinforcement (the reinforcement typically received in the world for performing the behavior). [9]
Walker (1990) presents an overview of token systems and combining such procedures with other interventions in the classroom. [10] He relates the comprehensiveness of token systems to the child's level of difficulty.
Another form of contingency management is voucher programs. In voucher-based contingency management patients earn vouchers exchangeable for retail items contingent upon objectively verified abstinence from recent drug use or compliance with other behavior-change targets. This particular form of contingency management was introduced in the early 1990s as a treatment for cocaine dependence. [11] [12] The approach is the most reliably effective method for producing cocaine abstinence in controlled clinical trials. [13] [14]
Medication take-home privileges is another form of contingency management frequently used in methadone maintenance treatment. Patients are permitted to "earn" take-home doses of their methadone in exchange for increasing, decreasing, or ceasing certain behaviors. For example, a patient may be given one take-home dose per week after submitting negative drug screens (generally via urine testing) for three months. (It is worth noting that take-home-doses (or "bottles") are seen as desirable rewards because they allow patients to come to the clinic less often to obtain their medication).
Based on applied behavior analysis (ABA), contingency management includes techniques such as choice and preference assessments, shaping, making contracts between the therapist and patient, community reinforcement approach and family training, and token economy.
Contingent vouchers are also used to cease smoking addictions. One study claims that people with substance use disorders can receive help with their addiction through the use of voucher-based treatment for smoking. In addition, nicotine replacement (NRT) can help with addiction combined with the vouchers. [15]
A meta-analysis of contingency management in drug programs showed that it has a large effect. [16] These contingencies are delivered based on abstinence and attendance goals [17] [18] and can take the form of vouchers, the opportunity to win prizes or privileges. They have been used with single problem addictions as well as dual diagnoses [19] [20] and homelessness. [21] Overall contingency management is an effective and cost-efficient addition to drug treatment. [22]
In contrast to these findings in a recent study, the researchers found out that nicotine replacement treatment only improved the effects of contingent vouchers on short-term smoking abstinence. However, in the long term, the effects of contingent vouchers had no impact on tobacco resistance. [15]
Level systems are often employed as a form of contingency management system. Level systems are designed such that once one level is achieved, then the person earns all the privileges for that level and the levels lower than it. [23]
Many organizations exist for board certified behavior analysts using contingency management programs around the world.
Substance abuse, also known as drug abuse, is the use of a drug in amounts or by methods that are harmful to the individual or others. It is a form of substance-related disorder. Differing definitions of drug abuse are used in public health, medical, and criminal justice contexts. In some cases, criminal or anti-social behavior occurs when the person is under the influence of a drug, and long-term personality changes in individuals may also occur. In addition to possible physical, social, and psychological harm, the use of some drugs may also lead to criminal penalties, although these vary widely depending on the local jurisdiction.
Drug rehabilitation is the process of medical or psychotherapeutic treatment for dependency on psychoactive substances such as alcohol, prescription drugs, and street drugs such as cannabis, cocaine, heroin, and amphetamines. The general intent is to enable the patient to confront substance dependence, if present, and stop substance misuse to avoid the psychological, legal, financial, social, and medical consequences that can be caused.
Opioid use disorder (OUD) is a substance use disorder characterized by cravings for opioids, continued use despite physical and/or psychological deterioration, increased tolerance with use, and withdrawal symptoms after discontinuing opioids. Opioid withdrawal symptoms include nausea, muscle aches, diarrhea, trouble sleeping, agitation, and a low mood. Addiction and dependence are important components of opioid use disorder.
Buprenorphine, sold under the brand name Subutex among others, is an opioid used to treat opioid use disorder, acute pain, and chronic pain. It can be used under the tongue (sublingual), in the cheek (buccal), by injection, as a skin patch (transdermal), or as an implant. For opioid use disorder, the patient must have moderate opioid withdrawal symptoms before buprenorphine can be administered under direct observation of a health-care provider.
In internal medicine, relapse or recidivism is a recurrence of a past condition. For example, multiple sclerosis and malaria often exhibit peaks of activity and sometimes very long periods of dormancy, followed by relapse or recrudescence.
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption of the drug. A drug addiction, a distinct concept from substance dependence, is defined as compulsive, out-of-control drug use, despite negative consequences. An addictive drug is a drug which is both rewarding and reinforcing. ΔFosB, a gene transcription factor, is now known to be a critical component and common factor in the development of virtually all forms of behavioral and drug addictions, but not dependence.
A token economy is a system of contingency management based on the systematic reinforcement of target behavior. The reinforcers are symbols or tokens that can be exchanged for other reinforcers. A token economy is based on the principles of operant conditioning and behavioral economics and can be situated within applied behavior analysis. In applied settings token economies are used with children and adults; however, they have been successfully modeled with pigeons in lab settings.
Drug addiction recovery groups are voluntary associations of people who share a common desire to overcome their drug addiction. Different groups use different methods, ranging from completely secular to explicitly spiritual. Some programs may advocate a reduction in the use of drugs rather than outright abstention. One survey of members found active involvement in any addiction recovery group correlates with higher chances of maintaining sobriety. Although there is not a difference in whether group or individual therapy is better for the patient, studies show that any therapy increases positive outcomes for patients with substance use disorders. The survey found group participation increased when the individual members' beliefs matched those of their primary support group. Analysis of the survey results found a significant positive correlation between the religiosity of members and their participation in twelve-step programs and to a lesser level in non-religious SMART Recovery groups, the correlation factor being three times smaller for SMART Recovery than for twelve-step addiction recovery groups. Religiosity was inversely related to participation in Secular Organizations for Sobriety.
Polysubstance dependence refers to a type of substance use disorder in which an individual uses at least three different classes of substances indiscriminately and does not have a favorite substance that qualifies for dependence on its own. Although any combination of three substances can be used, studies have shown that alcohol is commonly used with another substance. One study on polysubstance use categorized participants who used multiple substances according to their substance of preference. The results of a longitudinal study on substance use led the researchers to observe that excessively using or relying on one substance increased the probability of excessively using or relying on another substance.
Self-administration is, in its medical sense, the process of a subject administering a pharmacological substance to themself. A clinical example of this is the subcutaneous "self-injection" of insulin by a diabetic patient.
Substance use disorder (SUD) is the persistent use of drugs despite the substantial harm and adverse consequences to one's own self and others, as a result of their use. In perspective, the effects of the wrong use of substances that are capable of causing harm to the user or others, have been extensively described in different studies using a variety of terms such as substance use problems, problematic drugs or alcohol use, and substance use disorder.The National Institute of Mental Health (NIMH) states that "Substance use disorder (SUD) is a treatable mental disorder that affects a person's brain and behavior, leading to their inability to control their use of substances like legal or illegal drugs, alcohol, or medications. Symptoms can be moderate to severe, with addiction being the most severe form of SUD".Substance use disorders (SUD) are considered to be a serious mental illness that fluctuates with the age that symptoms first start appearing in an individual, the time during which it exists and the type of substance that is used. It is not uncommon for those who have SUD to also have other mental health disorders. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol (alcoholism); cannabis; opioids; stimulants such as nicotine (including tobacco), cocaine and amphetamines; benzodiazepines; barbiturates; and other substances.
Neonatal withdrawal or neonatal abstinence syndrome (NAS) or neonatal opioid withdrawal syndrome (NOWS) is a withdrawal syndrome of infants, caused by the cessation of the administration of licit or illicit drugs. Tolerance, dependence, and withdrawal may occur as a result of repeated administration of drugs or even after short-term high-dose use—for example, during mechanical ventilation in intensive care units. There are two types of NAS: prenatal and postnatal. Prenatal NAS is caused by discontinuation of drugs taken by the pregnant mother, while postnatal NAS is caused by discontinuation of drugs directly to the infant.
Addiction is a neuropsychological disorder characterized by a persistent and intense urge to use a drug or engage in a behavior that produces natural reward, despite substantial harm and other negative consequences. Repetitive drug use often alters brain function in ways that perpetuate craving, and weakens self-control. This phenomenon – drugs reshaping brain function – has led to an understanding of addiction as a brain disorder with a complex variety of psychosocial as well as neurobiological factors that are implicated in addiction's development.
The adolescent community reinforcement approach (A-CRA) is a behavioral treatment for alcohol and other substance use disorders that helps youth, young adults, and families improve access to interpersonal and environmental reinforcers to reduce or stop substance use.
About 1 in 7 Americans suffer from active addiction to a particular substance. Addiction can cause physical, psychological, and emotional harm to those who are affected by it. The American Society of Addiction Medicine defines addiction as "a treatable, chronic medical disease involving complex interactions among brain circuits, genetics, the environment, and an individual's life experiences. People with addiction use substances or engage in behaviors that become compulsive and often continue despite harmful consequences." In the world of psychology and medicine, there are two models that are commonly used in understanding the psychology behind addiction itself. One model is referred to as the disease model of addiction. The disease model suggests that addiction is a diagnosable disease similar to cancer or diabetes. This model attributes addiction to a chemical imbalance in an individual's brain that could be caused by genetics or environmental factors. The second model is the choice model of addiction, which holds that addiction is a result of voluntary actions rather than some dysfunction of the brain. Through this model, addiction is viewed as a choice and is studied through components of the brain such as reward, stress, and memory. Substance addictions relate to drugs, alcohol, and smoking. Process addictions relate to non-substance-related behaviors such as gambling, spending money, sexual activity, gaming, spending time on the internet, and eating.
Nathan H. Azrin was a behavioral modification researcher, psychologist, and university professor. He taught at Southern Illinois University and was the research director of Anna State Hospital between 1958 and 1980. In 1980 he became a professor at Nova Southeastern University, and entered emeritus status at the university in 2010. Azrin was the founder of several research methodologies, including Token Economics, the Community Reinforcement Approach (CRA) on which the CRAFT model was based, Family Behavior Therapy, and habit reversal training. According to fellow psychologist Brian Iwata “Few people have made research contributions equaling Nate’s in either basic or applied behaviour analysis, and none have matched his contributions to both endeavors.”
Community reinforcement approach and family training is a behavior therapy approach in psychotherapy for treating addiction developed by Robert J. Myers in the late 1970s. Meyers worked with Nathan Azrin in the early 1970s whilst he was developing his own community reinforcement approach (CRA) which uses operant conditioning techniques to assist those with addictions live healthily. Meyers adapted CRA to create CRAFT, which he described as CRA that "works through family members." CRAFT combines CRA with family training to equip concerned significant others (CSOs) of addicts with supportive techniques to encourage their loved ones to commence and continue treatment and provides them with defences against addiction's damaging effects on themselves.
Nancy M. Petry was a psychologist known for her research on behavioral treatments for addictive disorders, behavioral pharmacology, impulsivity and compulsive gambling. She was Professor of Medicine at the University of Connecticut Health Center. Petry served as a member of the American Psychiatric Association Workgroup on Substance Use Disorders for the DSM-5 and chaired the Subcommittee on Non-Substance Behavioral Addictions. The latter category includes Internet addiction disorder and problem gambling. She also served as a member of the Board of Advisors of Children and Screens: Institute of Digital Media and Child Development.
Treatment and management of addiction encompass the range of approaches aimed at helping individuals overcome addiction, most commonly in the form of substance use disorders and behavioral addictions. Effective treatment often includes a combination of medical, psychological, and social interventions tailored to the specific needs of the individual. Common practices to this end include detoxification, counseling, behavioral therapy, medication-assisted treatment, and support groups. The goal of addiction treatment is to reduce dependence, improve quality of life, and ultimately support long-term recovery. Comprehensive management addresses both the physical and psychological aspects of addiction, recognizing it as a chronic but treatable condition.
