Risk Perception-Based Project Contingency Management Framework

Project risk management (PRM) involves identifying risks, assessing their impact, and developing a contingency plan. A structured contingency management (CM) approach prevents subjective biases in analyzing risks and developing responses. Previous studies have either focused on improving the accuracy of risk estimates or analyzed, from a qualitative perspective, the relationships between perceived risk and project performance. This study aimed to improve PRM by providing a risk-perception-based contingency management framework (CMF). The CMF guides contingency depletion based on two short- and long-term cost overrun indicators and their respective thresholds. Thresholds and the initial contingency reserve amount are determined by applying the Monte Carlo method to a stochastic, discrete-event, finite-horizon, dynamic project simulation model. The study developed the CMF through a structured approach, validating the simulation model on eight specific project configurations. The results prove that the framework can be applied to any project, shaping the risk response strategy. This study contributes to PRM by explaining the relationships between risk perception and risk responses and providing a prescriptive CM tool.

Development of Mobile Contingency Management for Cannabis Use Reduction

Many interventions for cannabis use disorder (CUD) are associated with decreases in frequency and quantity of use but fail to increase overall rates of sustained abstinence. It is currently unknown whether reductions in use (in the absence of sustained abstinence) result in clinically significant improvements in functioning. The objective of this study was to refine a mobile contingency management approach to reduce cannabis use to ultimately evaluate whether reductions in frequency and quantity of cannabis are related to improvements in functional and mental health status. Three cohorts of participants (n = 18 total, n = 10 women) were enrolled and completed 2 weeks of ecological momentary assessment (EMA) during a baseline ad lib cannabis use period, followed by a 6-week reduction period. Participants completed EMA assessments multiple times per day and were prompted to provide videotaped saliva cannabis testing 2–3 times daily. Data from participants who were at least 80% adherent to all EMA prompts were analyzed (13 out of 18). During the ad lib phase, participants were using cannabis on 94% of the days and reported using a mean of 1.42 grams daily. The intervention was a mobile application that participants used to record cannabis use by saliva tests to bioverify abstinence and participants completed electronic diaries to report their grams used. During the 6-week intervention phase, participants reported reducing their use days to 47% of the days with a reported mean of .61 grams daily. In the last cohort, at least 50% of the heavy users were able to reduce their cannabis use by at least 50%. The effect of cannabis reduction (versus abstinence) is largely unknown. Observations suggest that it is possible to develop a mobile intervention to reduce cannabis use among heavy users, and this paradigm can be utilized in future work to evaluate whether reductions in cannabis use among heavy users will result in improvements in functional and mental health status.

Implications of epidemic-pandemic convergence for routine care adoption of contingency management: A case study.

The significant increase in opioid-related drug overdoses during the coronavirus disease (COVID-19) pandemic has put an unprecedented burden on hospital emergency departments, who saw as high as an approximate 150% increase in emergency department (ED) admission rates in the initial months of the pandemic. Although overdose is a clear sign of problem drug use, only a small proportion of nonfatal overdose patients enroll in treatment within 30 days of their overdose. To bridge the gap between opioid overdoses and treatment entry, a smartphone-smart debit card contingency management program was developed to promote entry into medication-assisted treatment by out-of-treatment opioid users who have recently received care in a hospital emergency department. The case study described in this article highlights a successful implementation of this intervention despite numerous disruptions related to COVID-19 that would have made engagement difficult without the remote access to contingency management provided by this technology. Patient status over time is presented in conjunction with contingency management earnings. Technology-based contingency management may provide improved scalability, rigorous outcomes metrics, and lower costs than prior onsite, manual contingency management (CM) approaches. The COVID-19 pandemic, in combination with the opioid epidemic has created a context in which historical obstacles to the adoption of contingency management may be overcome. This case study demonstrates the potential utility of smartphone-based contingency management when in-person care is difficult to access or disrupted. The requirement for further research demonstrating the efficacy of these approaches is discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Psychological Factors of Addition and Interventions for Substance Use Disorder

Substance use disorders appeared earlier in the history of human development with the discovery of alcohol and drugs. As society develops, more and more people exhibit substance abuse and substance addiction. Therefore, substance use disorders are gradually appearing in the limelight. This review begins with an analysis of the pathology and prevalence of substance use disorders, dividing those psychological factors that can lead to substance use disorders into internalizing and social factors. Five specific therapies, including cognitive behavioral therapy, mindfulness-based cognitive therapy, prize-based contingency management approach, cue-exposure therapy, and acceptance and commitment therapy, are analyzed and discussed, also categorized as internal promotion and external influence, based on how these therapies affect clients. Finally, for future research and treatment of substance use disorders, this review combines the previous literature and suggests ways to combine two or more therapies in order to achieve the best treatment results.

A contingency management approach for treatment of methamphetamine use disorder and human immunodeficiency virus antiretroviral treatment adherence in pregnancy to prevent mother-to-child transmission: a case report

IntroductionThis review highlights the rising prevalence of methamphetamine use in pregnancy in North American and the difficulty of managing active human immunodeficiency virus infection in a pregnant woman while actively using methamphetamines. Multidisciplinary medical teams with knowledge of addiction medicine, infectious disease management, and pregnancy are needed to provide combined expert care to reduce the harms associated with substance use and improve adherence to antiretroviral treatment. We report the case of a treatment-naïve pregnant patient with human immunodeficiency virus who was actively using methamphetamines. The patient was able to initiate and adhere to antiretroviral treatment while taking a prescription stimulant in a contingency management paradigm. To the best of our knowledge, this is the first documented case of prescription stimulants being used in pregnancy to improve adherence to antiretroviral medications.Case presentationA 32-year-old white woman with untreated human immunodeficiency virus, a newly diagnosed pregnancy, and actively using methamphetamines presented to a drop-in combined prenatal care and addiction medicine clinic. After initiating a prescription amphetamine in a contingency management paradigm, she was adherent to human immunodeficiency antiretroviral treatment and had a fully suppressed viral load throughout the remainder of her pregnancy.ConclusionActive treatment of methamphetamine use disorders with prescription stimulants, coupled with contingency management, may represent a mechanism to engage patients in care and improve adherence to antiretroviral treatment (and prevent mother-to-child-transmission of human immunodeficiency virus).

Assessing the Use and Impact of Points and Rewards across Four Federal Probation Districts: A Contingency Management Approach

ABSTRACTContingency management (CM) is a well-acknowledged behavioral approach for incentivizing changes in behavior and attitudes. A version of CM was piloted in four federal probation districts to determine whether systematically awarding points and rewards for key behaviors could be implemented and impact recidivism rates. A case controlled match design was conducted with a CM sample (referred to as Justice Steps (JSTEPS)) (n = 128) who were individually matched to a comparison sample (n = 128) on six variables related to recidivism. Analyses compared the number of technical violations and new arrests between JSTEPS participants and a historical comparison sample. Using Kaplan-Meier survival analysis, results indicate JSTEPS sites using early CM rewarding strategies tend to have delayed recidivism than others. A research agenda is outlined.

Contingency management intervention targeting co-addiction of alcohol and drugs among American Indian adults: Design, methodology, and baseline data.

American Indian adults have some of the highest alcohol abstinence rates compared to the overall US population. Despite this, many American Indian people are more likely to concurrently use alcohol and illicit drugs and are less likely to participate and remain in outpatient treatment for alcohol and other drug use compared to the general US population. There is limited knowledge about effective interventions targeting alcohol and drug co-addiction among American Indian adults. Contingency management is a behavioral intervention designed to increase drug abstinence by offering monetary incentives in exchange for drug and alcohol negative urine samples. We aim to evaluate and describe a culturally tailored contingency management intervention to increase alcohol and other drug abstinence among American Indian adults residing in a Northern Plains reservation. This 2 × 2 factorial, randomized controlled trial currently includes 114 American Indian adults with alcohol and/or drug dependence who are seeking treatment. Participants were randomized into one of four groups that received (1) contingency management for alcohol, (2) contingency management for other drug, (3) contingency management for both substances, or (4) no contingency management for either substance. We present descriptive, baseline data to characterize the sample and describe the modified contingency management approach that is specific to the community wherein this trial was being conducted. The sample is 49.1% male, with an average age of 35.8 years (standard deviation = 10.4 years). At baseline, 43.0% of the sample tested positive for ethyl glucuronide, 50.9% of participants self-reported methamphetamine as their most used drug, 36.8% self-reported cannabis, and 12.3% self-reported prescription opiates as their most used drug. Among randomized participants, 47.4% tested positive for cannabis, 28.1% tested positive for methamphetamine, 16.7% tested positive for amphetamines, and 2.1% tested positive for opiates. This is the first study to examine a culturally tailored contingency management intervention targeting co-addiction of two substances among American Indian adults. By establishing a tribal-university partnership to adapt, implement, and evaluate contingency management, we will increase the literature on evidence-based addiction treatments and research, while improving trust for addiction interventions among American Indian communities through ongoing collaboration. Moreover, results have implications for the use of contingency management as an intervention for co-addiction in any population.

Holacracy and Obliquity: contingency management approaches in organizing companies

The paper aims to examine the development of modern innovative management methods and practices such as Holacracy, Obliquity, Adhocracy and Sociocracy, which are novelty in the Management science and practice. The study illustrates contingency approaches in designing, managing and developing agile companies from wide varieties of industries. The paper sheds light on contemporary methods in organizing, planning and setting goals of companies in a post-knowledge era. It is like an operating system for business that requires the installation of different applications as applications for hiring employees, for setting salaries, for planning or logistics. In the paper, literature review on management innovations is conducted and subsequently statistical operationalization through STATA software has been employed to examine how particular organizations design and set up their organizational structures such as lean, agile or scrum. Paper results show that smaller companies are more agile and they tend to acquire Holacratic Management models thanks to the fact that self-managing teams exist internally and their organizational structures are flatter and more adaptive in comparison to the multinational corporations. Consequently, the paper concludes with suggestions on innovative management implementations for future development of companies and emphasizes the need for further research on what is the impact of Holacracy and Obliquity on shaping the organizational culture of companies.

Psychosocial and pharmacological interventions for the treatment of cannabis use disorder.

Cannabis use has been continuously increasing, and cannabis use disorder (CUD) has become a public health issue. Some psychosocial interventions have demonstrated the ability to reduce cannabis use; however, there are no pharmacotherapies approved for the treatment of CUD. Some drugs have shown limited positive effects on use and withdrawal symptoms, but no controlled studies have been able to show strong and persistent effects on clinically meaningful outcomes. The aim of this review is to synthesize the evidence from the available literature regarding the effectiveness of psychosocial and pharmacological treatments for CUD among adults (that is, 18 years old or older). An analysis of the evidence shows that the current best psychosocial intervention to reduce cannabis use is the combination of motivational enhancement therapy and cognitive-behavioral therapy, preferably accompanied by a contingency management approach. In regard to pharmacological interventions, there are mostly unclear findings. Some drugs, such as CB1 agonists, gabapentin, and N-acetylcysteine, have been shown to produce improvements in some symptoms of CUD in single studies, but these have not been replicated. Other classes of medications, including antidepressants and antipsychotics, have been unsuccessful in producing such effects. There is an imminent need for more clinical trials to develop more effective treatments for CUD.

Newborn birth-weight of pregnant women on methadone or buprenorphine maintenance treatment: A national contingency management approach trial.

Methadone maintenance treatment (MMT) is the gold standard for pregnant women with opioid use disorders. Still, low birth-weights were reported, in particular of mothers who became pregnant before admission to MMT. We studied whether an escalating incentive contingency-management approach may contribute to better newborn birth-weights. A nationwide controlled randomized trial among all Israeli methadone/buprenorphine maintenance treatment (MBMT), newly or already in treatment pregnant women was performed. A modified contingency-management protocol with coupons of escalating value depending upon reduction of drug use, cigarette smoking, and alcohol consumption was compared to standard care arm. Drugs in urine, smoking (Fagerstrom score), alcohol use, and depression were monitored. Thirty-five women had 46 pregnancies. In their first pregnancy, 19 from the contingency-management and 16 from the standard care arms were studied. Contingency-management group as compared to the standard care arm included more newly admitted women (36.8% vs. 6.3%, p = .05), with benzodiazepine and cannabis onset at a younger age, and higher proportion of any drug abuse while pregnant (100% vs. 68.8%, p = .01). Fifteen of the contingency-management and 14 of the control arm gave birth (78.9% vs. 87.5%, p = .3) with similar proportions of normal (>2,500 g) birth-weight (71.4% vs. 61.5%, p = .8). Newborns' birth-weight was comparable among the two study arms indicating no contribution of the contingency-management approach. Small sample and baseline differences between arms might have influenced results. Intensive intervention should be evaluated on a larger scale of participants. (Am J Addict 2017;26:167-175).

A Fast Contingency Management Approach with Optimal Placement and Tuning of Interline Power Flow Controller Using Differential Evolution Algorithm

In the traditional approach of steady-state contingency screening, each line is removed sequentially and its effect on the system is studied, while only some contingencies may cause certain lines to become severe. This article presents an approach for fast contingency ranking in steady-state, based on the selection of a limited number of important buses. A composite severity index based placement of interline power flow controller and tuning using differential evolution for IEEE 14- and 30-bus systems has also been proposed. The composite severity index is a combination of line utilization factor and fast voltage stability index. All the lines connected to the important buses only are sequentially considered for line outage and the most severe line corresponding to each outage is ranked on the basis of composite severity index. An interline power flow controller is optimally placed and tuned to improve the system post-contingency condition. Differential evolution has been used to tune the device for a multi-objective function. The load on the system is increased to test the performance of the interline power flow controller under highly stressed conditions.

Neurobehavioural approaches to the rehabilitation of challenging behaviour

Neurobehavioural disability (NBD) following acquired brain injury undermines capacity for independent social behaviour and results in serious long-term social handicap. The presence of challenging behaviour as a feature of NBD has obvious implications for rehabilitation and community reintegration. Behavioural approaches are seen by many as fundamental to the successful rehabilitation of challenging behaviour. This paper will a) define the nature of neurobehavioural rehabilitation; b) explore the characteristics of cases referred, and c) the outcomes achieved. Strengths, limitations and future developments of neurobehavioural approaches for challenging behaviour will be considered along with potential factors that limit generalisation and longevity of treatment gains. Literature review. Neurobehavioural services are distinguishable from other forms of neurorehabilitation. There is considerable evidence supporting the central role of both positive behaviour supports and contingency management approaches in creating conditions that minimise neurocognitive impairment, facilitate new learning, and ensure a positive social climate in both specialised inpatient units and community settings. Possible limitations include over-reliance on evidence from successful accounts of single cases and lack of knowledge regarding generalisation. Neurobehavioural rehabilitation is effective and can save care costs in the long term. More evidence regarding maintenance of gains is required.

A developmental perspective on neuroeconomic mechanisms of contingency management.

This paper provides a developmental overview of relevant theory and research on delay discounting and neuroeconomics, and their implications for contingency management (CM) approaches to treatment. Recent advances in the neuroscience of decision making have the potential to inform treatment development for adolescent substance use in general, and CM treatments in particular. CM interventions may be informed by research on delay discounting, a type of decision making that reflects how individuals value immediate versus delayed rewards. Delay discounting reliably distinguishes substance abusers from nonabusers and is a significant predictor of individual differences in response to substance use treatments. Discounting may also be important in predicting response to CM, as CM attempts to directly influence this decision-making process, shifting the preference from the immediate rewards of use to delayed rewards for choosing not to use. Multiple neural processes underlie decision making, and those processes have implications for adolescent substance abuse. There are significant neurodevelopmental processes that differentiate adolescents from adults. These processes are implicated in delay discounting, suggesting that adolescence may reflect a period of plasticity in temporal decision making. Understanding the neural mechanisms of delay discounting has led to promising working memory interventions directly targeting the executive functions that underlie individual choices. These interventions may be particularly helpful in combination with CM interventions that offer immediate rewards for brief periods of abstinence, and may show particular benefit in adolescence due to the heightened neural plasticity of systems that underlie temporal discounting in adolescence.

Adding positive reinforcement in justice settings: Acceptability and feasibility

Although contingency management (CM) approaches are among the most promising methods for initiating drug abstinence (S. T. Higgins, S. M. Alessi, & R. L. Dantona, 2002; S. T. Higgins, S. H. Heil, & J. P. Lussier, 2004), adoption and implementation of CM protocols into treatment programs are both challenging and infrequent. In criminal justice agencies, where roughly 70% of clients report substance abuse issues (F. S. Taxman, K. L. Cropsey, D. W. Young, & H. Wexler, 2007), CM interventions are virtually nonexistent. The Justice Steps (JSTEPS) study uses a longitudinal, mixed-method design to examine the implementation of a CM-based protocol in five justice settings. This article presents qualitative data collected during Phase 1 of the JSTEPS project regarding the acceptability and feasibility of CM in these justice settings. The study finds a level of acceptability (find CM tolerable) and feasibility (find CM suitable) within justice agencies, but with some challenges. These challenges are reflected in the following: (a) incorporating too many desired target behaviors into CM models; (b) facing intraorganizational challenges when designing CM systems; and (c) emphasizing sanctions over rewards despite the evidence-base for positive reinforcers. These findings have implications for advancing the dissemination, adoption, and implementation of evidence-based treatments (and CM in particular) in criminal justice settings.

Methadone prescribing under supervised consumption on premises: A Scottish clinician's perspective on prescribing practice

Specialist services have increased their capacity considerably in recent years to initiate and/or provide ongoing treatment for drug misuse. Consequently, methadone prescribing has substantially increased and over 17,000 patients are currently receiving methadone. Clinical guidance promotes consumption on the premises (COP) initially to ensure patients take medication as prescribed and also to prevent diversion. Diversion poses two risks: the patient may remain under-treated and continue illicit heroin use; diverted drugs put others at risk. However, COP can be restrictive. Current UK guidance is vague and not evidence-based recommending 'around three months subject to assessment of compliance and individual circumstances'. The overall aim of this study was to describe clinical practice regarding prescribing methadone under COP in Scotland, and reasons for this. Design and Methods. A structured, postal questionnaire was sent to all lead clinicians in specialist drug treatment centres in Scotland in 2009 (n=42). The questionnaire explored current practice, influence of supervision on retention, views of best practice and contingency management. The response rate was 76% (n=32). Clinicians usually supervise for a minimum of three months with patient-centred criteria used to determine when to reduce or stop COP. Employment, clinical stability, family support and concerns for the safety of children in the home influenced decision making. Contingency management approaches to supervision were widely used (62%). In Scotland, clinicians' practice is variable and individualised to patients, but generally cautious regarding relaxing supervision conditions. This may reflect the lack of evidence-based guidance.

Smoking Cessation in Recovery: Comparing 2 Different Cognitive Behavioral Treatments

Objectives The purpose of this pilot demonstration study was to evaluate the feasibility and effectiveness of adding a contingency management (CM) component to the standard cognitive-behavioral smoking cessation treatment offered to veterans in a residential substance-abuse treatment program. Specifically, we assessed the impact of CM on (1) engagement in smoking cessation treatment, (2) retention in smoking cessation treatment, and (3) abstinence from smoking. Methods Participants were 65 male veterans in inpatient treatment for a primary substance use disorder who expressed interest in quitting smoking. Participants were enrolled in either the standard or CM smoking cessation treatment program. All participants were offered 4 sessions of cognitive-behavioral group counseling; participants in the CM program also had the opportunity to earn cash vouchers for session attendance and abstinence from smoking. Results The CM treatment program showed superior treatment engagement and retention rates. Survival analysis showed that 58% of participants receiving the CM treatment were smoke-free on quit day, versus only 17% of participants in standard care. In addition, the end of treatment continuous abstinence rate was significantly higher in the CM condition compared with standard care (21% vs. 0%). Conclusions These preliminary results suggest that contingency management approaches may be useful for maximizing participation in smoking cessation treatment and improving treatment outcomes among recovering substance users.

Coping skills training and contingency management treatments for marijuana dependence: exploring mechanisms of behavior change

Achieving abstinence in the treatment of marijuana dependence has been difficult. To date the most successful treatments have included combinations of motivation enhancement treatment (MET) plus cognitive-behavioral coping skills training (CBT) and/or contingency management (ContM) approaches. Although these treatment approaches are theoretically based, their mechanisms of action have not been explored fully. The purpose of the present study was to explore mechanisms of behavior change from a marijuana treatment trial in which CBT and ContM were evaluated separately and in combination. A dismantling design was used in the context of a randomized clinical trial. The setting was an out-patient treatment research facility located in a university medical center. Participants were 240 adult marijuana smokers, meeting criteria for cannabis dependence. Participants were assigned to one of four 9-week treatment conditions: a case management control condition, MET/CBT coping skills training, ContM and MET/CBT + ContM. Outcome measures were total 90-day abstinence, recorded every 90 days for 12 months post-treatment. Regardless of treatment condition, abstinence in near-term follow-ups was predicted most clearly by abstinence during treatment, but long-term abstinence was predicted by use of coping skills and especially by post-treatment self-efficacy for abstinence. It was concluded that the most efficacious treatments for marijuana dependence are likely to be those that increase self-efficacy.

Contingency management in cocaine abusers: A dose-effect comparison of goods-based versus cash-based incentives.

Goods-based contingency management interventions (e.g., those using vouchers or prizes as incentives) have demonstrated efficacy in reducing cocaine use, but cost has limited dissemination to community clinics. Recent research suggests that development of a cash-based contingency management approach may improve treatment outcomes while reducing operational costs of the intervention. However, the clinical safety of providing cash-based incentives to substance abusers has been a concern. The present 16-week study compared the effects of goods-based versus cash-based incentives worth $0, $25, $50, and $100 on short-term cocaine abstinence in a small sample of cocaine-dependent methadone patients (N = 12). A within-subject design was used; a 9-day washout period separated each of 8 incentive conditions. Higher magnitude ($50 and $100) cash-based incentives (checks) produced greater cocaine abstinence compared with the control ($0) condition, but a magnitude effect was not seen for goods-based incentives (vouchers). A trend was observed for greater rates of abstinence in the cash-based versus goods-based incentives at the $50 and $100 magnitudes. Receipt of $100 checks did not increase subsequent rates of cocaine use above those seen in control conditions. The efficacy and safety data provided in this and other recent studies suggest that use of cash-based incentives deserves consideration for clinical applications of contingency management, but additional confirmation in research using larger samples and more prolonged periods of incentive delivery is needed.

Contingency Management for the Treatment of Methamphetamine Use Disorders

Theory and some preliminary evidence suggest that contingency management may be an effective treatment strategy or adjunct to psychosocial treatment for methamphetamine use disorders. An experimentally rigorous investigation on the topic was provided by a large multisite trial conducted under the auspices of the Clinical Trials Network of the National Institute on Drug Abuse. The authors report data on 113 participants who were diagnosed with methamphetamine abuse or dependence. They were randomly assigned to receive 12 weeks of either treatment as usual or treatment as usual plus contingency management. Urine samples were tested for illicit drugs, and breath samples were tested for alcohol. The reinforcers for drug-negative samples were plastic chips, some of which could be exchanged for prizes. The number of plastic chips drawn increased with each week of negative samples but was reset to one after a missed or positive sample. The participants in both groups remained in treatment for equivalent times, but those receiving contingency management in addition to usual treatment submitted significantly more negative samples, and they were abstinent for a longer period of time (5 versus 3 weeks). These results suggest that contingency management has promise as a component in treatment strategies for methamphetamine use disorder.
