Abstract
Contingency Management (CM) is a psychological treatment that aims to change behavior with financial incentives. In substance use disorders (SUDs), deployment of CM has been enriched by longstanding discussions around the cost-effectiveness of prized-based and voucher-based approaches. In prize-based CM, participants earn draws to win prizes, including small incentives to reduce costs, and the number of draws escalates depending on the duration of maintenance of abstinence. In voucher-based CM, participants receive a predetermined voucher amount based on specific substance test results. While both types have enhanced treatment outcomes, there is room for improvement in their cost-effectiveness: the voucher-based system requires enduring financial investment; the prize-based system might sacrifice efficacy. Previous work in computational psychiatry of SUDs typically employs frameworks wherein participants make decisions to maximize their expected compensation. In contrast, we developed new frameworks that clinical decision-makers choose actions, CM structures, to reinforce the substance abstinence behavior of participants. We consider the choice of the voucher or prize to be a sequential decision, where there are two pivotal parameters: the prize probability for each draw and the escalation rule determining the number of draws. Recent advancements in Reinforcement Learning, more specifically, in off-policy evaluation, afforded techniques to estimate outcomes for different CM decision scenarios from observed clinical trial data. We searched CM schemas that maximized treatment outcomes with budget constraints. Using this framework, we analyzed data from the Clinical Trials Network to construct unbiased estimators on the effects of new CM schemas. Our results indicated that the optimal CM schema would be to strengthen reinforcement rapidly in the middle of the treatment course. Our estimated optimal CM policy improved treatment outcomes by 32% while maintaining costs. Our methods and results have broad applications in future clinical trial planning and translational investigations on the neurobiological basis of SUDs.

Abstract
Background Clinical trials that include contingency management for smoking cessation have shown promising results for short-term quitting, but none have explored this approach for long-term abstinence in people experiencing homelessness. We designed a clinical trial of an extended contingency management intervention for smoking cessation for people experiencing homelessness. This study has two aims: (1) to explore tobacco use behaviors, and views toward smoking cessation, and (2) to explore factors influencing acceptability of engaging in such a trial in a sample of adult smokers experiencing homelessness. Methods We administered a questionnaire to obtain information on tobacco use behaviors and conducted in-depth, semi-structured interviews with 26 patients who had experienced homelessness and were patients at a safety net health clinic in San Francisco, California, where we planned to pilot the intervention. We obtained information on triggers for tobacco use, prior cessation experiences, attitudes toward cessation, attitudes toward engaging in a clinical trial for cessation, and factors that might influence participation in our proposed contingency management clinical trial. We analyzed transcripts using content analysis. Results Participants described the normative experiences of smoking, co-occurring substance use, and the use of tobacco to relieve stress as barriers to quitting. Despite these barriers, most participants had attempted to quit smoking and most were interested in engaging in a clinical trial as a method to quit smoking. Participants noted that desirable features of the trial include: receiving financial incentives to quit smoking, having a flexible visit schedule, having the study site be easily accessible, and having navigators with lived experiences of homelessness. Conclusion A patient-centric clinical trial design that includes incentives, flexible visits and navigators from the community may increase feasibility of engaging in clinical trials among individuals experiencing homelessness.

Contingency management to promote smoking cessation in people experiencing homelessness: Leveraging the electronic health record in a pilot, pragmatic randomized controlled trial.

Abstract
BACKGROUND Cigarette smoking is disproportionately high among people experiencing homelessness (PEH). Contingency management (CM) is a strategy that has shown considerable efficacy for smoking cessation and has been used in short-term studies of smoking abstinence in PEH. We describe a pilot, pragmatic randomized controlled trial protocol, which leverages an electronic health record (EHR) infrastructure to assess the feasibility and acceptability of an extended CM intervention to improve long-term abstinence in PEH. METHODS We will conduct the study at three safety-net clinics in San Francisco among 90 adults experiencing homelessness who smoke cigarettes currently and have a desire to quit. We will encourage all participants to receive smoking cessation services that include behavioral counseling and pharmacotherapy through their clinics. We will randomly assign participants to an extended CM intervention group with escalating incentives contingent on abstinence or to a control group with fixed incentives for attending study visits. We will use the EHR to recruit participants, track receipt of counseling and pharmacotherapy during clinical care, and communicate with providers on participants' progress. CM participants will get escalating incentives for demonstration of carbon monoxide-verified abstinence over 6 months, with a total possible earnings of $475. Control participants will receive a fixed incentive of $5 for attending study visits, totaling $125. We will conduct the carbon-monoxide verified abstinence assessments-which will determine CM incentive amounts-daily during week 1, bi-weekly through week 4, weekly through week 13, and monthly through week 24. Measures of feasibility and acceptability, both quantitative and qualitative, will include assessments of screening and recruitment, adherence to study visits, engagement in smoking cessation clinical care, retention, and participant satisfaction. One of the primary clinical outcomes will be biochemically verified 7-day point prevalence abstinence at 6 months. We will measure secondary outcomes, which will include 7-day point prevalence abstinence at 2 weeks, 3 and 12 months. DISCUSSION This trial will allow us to assess the feasibility and acceptability of a CM cessation intervention among PEH. The protocol's clinical setting and use of EHRs gives it significant potential for scalability. If found to be feasible, acceptable, and subsequently efficacious in a larger trial, the intervention could reduce tobacco-related health disparities by increasing long-term smoking abstinence among this vulnerable population. TRIAL REGISTRATION ClinicalTrials.gov NCT04982952. Registered on July 29, 2021.

Effectiveness of Incentives for Improving Diabetes-Related Health Indicators in Chronic Disease Lifestyle Modification Programs: a Systematic Review and Meta-Analysis. Prev Chronic Dis 2022; 19:E66.

Abstract
INTRODUCTION We examined the effectiveness of providing incentives to participants in lifestyle modification programs to improve diabetes-related health indicators: body weight, body mass index (BMI), blood pressure, cholesterol, and hemoglobin A1C (HbA1C). We also examined the potential effect of 4 different incentive domains (ie, type, monetary value, attainment certainty, and schedule) on those indicators. METHODS We searched Medline, Embase, PsycINFO, and Cochrane Library to identify relevant studies published from January 2008 through August 2021. We used a random-effects model to pool study results and examine between-study heterogeneity by using the I2 statistic and the Cochran Q test. We also conducted moderator analyses by using a mixed-effects model to examine differences between subgroups of incentive domains (eg, incentive type [cash vs other types]). RESULTS Our search yielded 10,965 articles, of which 19 randomized controlled trials met our selection criteria. The random-effects model revealed that, relative to the control group, the incentive group had significant reductions in weight (-1.85kg; 95% CI, -2.40 to -1.29; P < .001), BMI (-0.47kg/m2; 95% CI, -0.71 to -0.22; P < .001), and both systolic blood pressure (-2.59 mm HG; 95% CI, -4.98 to -0.20; P = .03) and diastolic blood pressure (-2.62 mm Hg; 95% CI, -4.61 to -0.64; P = .01). A reduction in cholesterol level was noted but was not significant (-2.81 mg/dL; 95% CI, -8.89 to -3.28; P = .37). One study found a significant reduction in hemoglobin A1c (-0.17%; 95% CI, -0.30% to -0.05%; P < .05). The moderator analyses showed that the incentive effect did not vary significantly between the subgroups of the incentive domains, except on weight loss for the attainment certainty domain, suggesting that a variety of incentive subgroups could be equally useful. CONCLUSION Providing incentives in lifestyle modification programs is a promising strategy to decrease weight, BMI, and blood pressure.

Abstract
Early in the COVID-19 pandemic, journalists and scholars noted differences between Asians and North Americans in their support for public mask use. These differences were primarily assumed to be due d to variations in ethnocultural norms and practices. To better ascertain people's motives for wearing masks and potential cultural differences in these rationales, this comparative, mixed-methods research examines Chinese and non-East Asian Canadians' mask use attitudes utilizing online group interviews (Study 1) and a nation-wide survey (Study 2) Study 1, conducted in the early stages of the pandemic, captured an ambivalent, yet evolving attitude toward public mask use among the non-East Asian Canadians, which differed from their Chinese counterparts who more uniformly perceived mask use favorably. Study 2, conducted 2 months later, suggests that both groups primarily wore masks for disease protection- and prevention-related reasons. However, age and education appeared to influence the mask wearing frequency of the non-East Asian Canadians, for whom public mask use was less prevalent and normative. The attitudinal differences in public mask use call for targeted strategies to support mask wearing for different ethnocultural groups, which may be achieved partially through enhancing interethnic understanding on the diversified use of and opinions about masks. The findings suggest that favorable social norms, along with evidence-based information campaigns involving personal appeals may encourage greater mask use by the non-East Asian population.

Abstract
INTRODUCTION Low participation and adherence to cardiac rehabilitation (CR) leads to ineffective care and increased risk of cardiac complications. There is a need to identify effective motivational strategies and concepts to increase participation and adherence to CR. PURPOSE The aim of this review was to synthesize and integrate the current knowledge about motivational strategies and concepts to increase participation and adherence to CR. METHODS A literature search was performed using five electronic databases: CINAHL, Medline via PubMed, Scopus, Embase, and Rehabilitation & Sports Medicine Source. The search was limited to peer-reviewed studies, written in English, and publications from 2010 to 2019. A matrix and narrative synthesis were employed to organize and synthesize the findings, respectively. RESULTS Eight of 522 articles met the inclusion criteria. Four articles used motivational interviewing (MotI) and counseling strategy, three articles investigated the autonomy, competence, and relatedness of self-determination theory (SDT) concepts, and one article used a reinforced motivational strategy. Use of MotI led to improving the CR completion rate from 14% to 39%. The number of sessions attended/patient improved from 12 to 20 when the staff was provided attendance feedback and a reward. Autonomy, competence, and relatedness motivated patients to participate in and adhere to CR. CONCLUSIONS Motivational interviewing and counseling, motivational and reinforcement strategies, and the autonomy, competence, and relatedness of SDT concepts should be utilized to promote participation and motivation for CR. The effects of these techniques on long-term CR require further research, including combining the identified methods to investigate the efficacy of these techniques on CR adherence.

Abstract
BACKGROUND Both theoretical and empirical evidence supports the potential of modest financial incentives to increase the reach of evidence-based weight control programs. However, few studies exist that examine the best incentive design for achieving the highest reach and representativeness at the lowest cost and whether or not incentive designs may be valued differentially by subgroups that experience obesity-related health disparities. METHODS A discrete choice experiment was conducted (n = 1232 participants; over 90% of them were overweight/obese) to collect stated preference towards different financial incentive attributes, including reward amount, program location, reward contingency, and payment form and frequency. Mixed logit and conditional logit models were used to determine overall and subgroup preference ranking of attributes. Using the National Health and Nutrition Examination Survey data sample weights and the estimated models, we predicted US nationally representative participation rates by subgroups and examined the effect of offering more than one incentive design. External validity was checked by using a completed cluster randomized control trial. RESULTS There were significant subgroup differences in preference toward incentive attributes. There was also a sizable negative response to larger incentive amounts among African Americans, suggesting that higher amounts would reduce participation from this population. We also find that offering participants a menu of incentive designs to choose from would increase reach more than offering higher reward amounts. CONCLUSIONS We confirmed the existence of preference heterogeneity and the importance of subgroup-targeted incentive designs in any evidence-based weight control program to maximize population reach and reduce health disparities.

Abstract
BACKGROUND Research participant engagement, which we define as recruitment and retention in clinical trials, is a costly and challenging issue in clinical research. Research teams have leveraged a variety of strategies to increase research participant engagement in clinical trials, although a framework and evidence for effective participant engagement strategies are lacking. We (1) developed a novel conceptual framework for strategies used to recruit and retain participants in clinical trials based on their underlying behavioral principles and (2) categorized empirically tested recruitment and retention strategies in this novel framework. METHODS We conducted a synthetic analysis of interventions tested in studies from two Cochrane reviews on clinical trial recruitment and retention, which included studies from 1986 to 2015. We developed a conceptual framework of behavioral strategies for increasing research participant engagement using deductive and inductive approaches with the studies included in the Cochrane reviews. Reviewed interventions were then categorized using this framework. We examined the results of reviewed interventions and categorized the effects on clinical trial recruitment and retention as significantly positive, null, or significantly negative; summary statistics are presented for the frequency and effects of each behavioral strategy type. RESULTS We analyzed 141 unique interventions across 96 studies: 91 interventions targeted clinical trial research participant recruitment and 50 targeted retention. Our framework included 14 behavioral strategies to improve research participant engagement grouped into four general approaches: changing attitudes by appealing to social motivators, changing attitudes by targeting individual psychology, reducing barriers and cognitive burdens, and providing incentives. The majority of interventions (54%) aimed to reduce barriers or cognitive burdens, with improving comprehension (27%) as the most common specific strategy identified. For recruitment, the most common behavioral strategies tested were building legitimacy or trust (38%) and framing risks and benefits (32%), while financial or material incentives (32%) and reducing financial, time, and social barriers (32%) were most common for retention interventions. Among interventions tested in randomized controlled trials, 51% had a null effect on research participant engagement, and 30% had a statistically significant positive effect. DISCUSSION Clinical researchers have tested a wide range of interventions that leverage distinct behavioral strategies to achieve improved research participant recruitment and retention. Common behavioral strategies include building legitimacy or trust between research teams and participants, as well as improving participant comprehension of trial objectives and procedures. The high frequency of null effects among tested interventions suggests challenges in selecting the optimal interventions for increasing research participant engagement, although the proposed behavioral strategy categories can serve as a conceptual framework for developing and testing future interventions.

Abstract
There is a long history of racial and ethnic disparities in healthcare and they continue to persist in contemporary society. These disparities have the potential to negatively affect morbidity and mortality in racial and ethnic minorities diagnosed with laryngeal cancer. Diagnosis, medical treatment, and rehabilitation for laryngeal cancer have improved considerably, leading to improvements in overall survival rates and physical, social, and psychological functioning. Yet members of minority and underrepresented groups are at an increased risk for experiencing reduced access to quality care and delays between diagnosis and treatment, and as a result have lower survival rates. Increasing health providers' awareness of racial and ethnic disparities in laryngeal cancer is necessary to facilitate changes in patient and provider education, clinical practice, and health policies. The purpose of this review is to summarize current literature on disparities in laryngeal cancer diagnosis, treatment, and rehabilitation among Black and Hispanic patients. We present recent data from the Surveillance, Epidemiology, and End Results database to examine trends in laryngeal cancer and patient, provider, and health systems factors that may perpetuate these disparities. In addition, we offer interventions to address racism and other racial and ethnic biases in laryngeal cancer care and describe research and legislative actions that are needed to reduce disparities in this area.

Abstract
Background Aboriginal and Torres Strait Islander peoples continue to experience poorer health outcomes than other population groups. While data specific to Indigenous Australians are scarce, a known social health literacy gradient exists linking low health literacy and poor health outcomes within many minority populations. Improving health literacy among Indigenous Australians is an important way to support self-determination and autonomy in both individuals and communities, by enhancing knowledge and improving health outcomes. This review aims to rigorously examine the effectiveness of health literacy interventions targeting Aboriginal and Torres Strait Islander peoples. Methods A systematic review across six databases (The Cochrane Library, PubMed, Embase, SCOPUS, ProQuest Dissertation and Thesis and Web of Science) was performed for publications evaluating interventions to improve health literacy among Indigenous Australian adults using search terms identifying a range of related outcomes. Results Of 824 articles retrieved, a total of five studies met the eligibility criteria and were included in this review. The included studies evaluated the implementation of workshops, structured exercise classes and the provision of discounted fruit and vegetables to improve nutrition, modify risk factors for chronic diseases, and improve oral health literacy. All interventions reported statistically significant improvement in at least one measured outcome. However, there was limited involvement of the Aboriginal and Torres Strait Islander community members in the research process and participant retention rates were sub-optimal. Conclusion There is limited evidence on interventions to improve health literacy in Indigenous Australian adults. Participation in interventions was often suboptimal and loss to follow-up was high. Future studies co-designed with Aboriginal and Torres Strait Islander community members are needed to improve health literacy in this population.

Abstract
A mental health professional shortage area (MHPSA) is an area lacking psychiatrists as designated by the Health Resources and Services Administration. Prior research found the lack of psychiatrists can be directly related to adverse health outcomes. The current investigation focused on the United States by state level and the relationship between MHPSAs, suicide rates, and access to professional counselors. Results from a cross-sectional analysis found MHPSAs were highly correlated with suicide deaths. There was a significant inverse relationship between number of professional counselors in an area and suicide deaths, and being uninsured was highly related to MHPSA and suicide. The results support the need for access to professional counselors. Policies incentivizing professional counselors to work in MHPSAs are needed because of their potential role in minimizing suicide deaths.

Workshop on the Development and Evaluation of Digital Therapeutics for Health Behavior Change: Science, Methods, and Projects. JMIR Ment Health 2020; 7:e16751. [PMID: 32130155 PMCID: PMC7066510 DOI: 10.2196/16751] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 12/11/2019] [Accepted: 12/15/2019] [Indexed: 12/22/2022] Open
Abstract
The health care field has integrated advances into digital technology at an accelerating pace to improve health behavior, health care delivery, and cost-effectiveness of care. The realm of behavioral science has embraced this evolution of digital health, allowing for an exciting roadmap for advancing care by addressing the many challenges to the field via technological innovations. Digital therapeutics offer the potential to extend the reach of effective interventions at reduced cost and patient burden and to increase the potency of existing interventions. Intervention models have included the use of digital tools as supplements to standard care models, as tools that can replace a portion of treatment as usual, or as stand-alone tools accessed outside of care settings or direct to the consumer. To advance the potential public health impact of this promising line of research, multiple areas warrant further development and investigation. The Center for Technology and Behavioral Health (CTBH), a P30 Center of Excellence supported by the National Institute on Drug Abuse at the National Institutes of Health, is an interdisciplinary research center at Dartmouth College focused on the goal of harnessing existing and emerging technologies to effectively develop and deliver evidence-based interventions for substance use and co-occurring disorders. The CTBH launched a series of workshops to encourage and expand multidisciplinary collaborations among Dartmouth scientists and international CTBH affiliates engaged in research related to digital technology and behavioral health (eg, addiction science, behavioral health intervention, technology development, computer science and engineering, digital security, health economics, and implementation science). This paper summarizes a workshop conducted on the Development and Evaluation of Digital Therapeutics for Behavior Change, which addressed (1) principles of behavior change, (2) methods of identifying and testing the underlying mechanisms of behavior change, (3) conceptual frameworks for optimizing applications for mental health and addictive behavior, and (4) the diversity of experimental methods and designs that are essential to the successful development and testing of digital therapeutics. Examples were presented of ongoing CTBH projects focused on identifying and improving the measurement of health behavior change mechanisms and the development and evaluation of digital therapeutics. In summary, the workshop showcased the myriad research targets that will be instrumental in promoting and accelerating progress in the field of digital health and health behavior change and illustrated how the CTBH provides a model of multidisciplinary leadership and collaboration that can facilitate innovative, science-based efforts to address the health behavior challenges afflicting our communities.

The smoking cessation in pregnancy incentives trial (CPIT): study protocol for a phase III randomised controlled trial. Trials 2020; 21:183. [PMID: 32059684 PMCID: PMC7023794 DOI: 10.1186/s13063-019-4042-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 12/30/2019] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Eighty per cent of UK women have at least one baby, making pregnancy an opportunity to help women stop smoking before their health is irreparably compromised. Smoking cessation during pregnancy helps protect infants from miscarriage, still birth, low birth weight, asthma, attention deficit disorder and adult cardiovascular disease. UK national guidelines highlight lack of evidence for effectiveness of financial incentives to help pregnant smokers quit. This includes a research recommendation: within a UK context, are incentives an acceptable, effective and cost-effective way to help pregnant women who smoke to quit? METHODS The Cessation in Pregnancy Incentives Trial (CPIT) III is a pragmatic, 42-month, multi-centre, parallel-group, individually randomised controlled superiority trial of the effect on smoking status of adding to usual Stop Smoking Services (SSS) support, the offer of up to £400 of financial voucher incentives, compared with usual support alone, to quit smoking during pregnancy. Participants (n = 940) are pregnant smokers (age > 16 years, < 24 weeks pregnant, English speaking), who consent via telephone to take part and are willing to be followed-up in late pregnancy and 6 months after birth. The primary outcome is cotinine/anabasine-validated abstinence from smoking in late pregnancy. Secondary outcomes include engagement with SSS, quit rates at 4 weeks from agreed quit date and 6 months after birth, and birth weight. Outcomes will be analysed by intention to treat, and regression models will be used to compare treatment effects on outcomes. A meta-analysis will include data from the feasibility study in Glasgow. An economic evaluation will assess cost-effectiveness from a UK NHS perspective. Process evaluation using a case-study approach will identify opportunities to improve recruitment and learning for future implementation. Research questions include: what is the therapeutic efficacy of incentives; are incentives cost-effective; and what are the potential facilitators and barriers to implementing incentives in different parts of the UK? DISCUSSION This phase III trial in Scotland, England and Northern Ireland follows a successful phase II trial in Glasgow, UK. The participating sites have diverse SSS that represent most cessation services in the UK and serve demographically varied populations. If found to be acceptable and cost-effective, this trial could demonstrate that financial incentives are effective and transferable to most UK SSS for pregnant women.

Abstract
This Special Issue of Preventive Medicine (PM) is the 6th in a series on behavior change, health, and health disparities. This is a topic of critical importance to improving U.S. population health. There is broad consensus that personal behavior patterns or lifestyle such as substance abuse, physical inactivity/obesity, and non-adherence with medical regimens are among the most important modifiable causes of chronic disease, premature death and population health. Hence, effectively promoting health-related behavior change needs to be a key component of health care research and policy. In this issue we devote the majority of space (14 of 20 reports) to the U.S. opioid epidemic, especially the ongoing but still woefully inadequate efforts to build the necessary clinical infrastructure in rural communities to effectively address the epidemic. The remaining six reports focus on addressing the substantive challenges that tobacco use and non-adherence with medical regimens represent in these same communities. While giving the opioid epidemic the attention that it well deserves, we cannot afford to do so at the expense of these other longstanding and also devastating public health problems. Across each of these topics we include contributions from well-regarded investigators, clinicians, and policymakers to acquaint readers with recent accomplishments while also noting knowledge gaps and unmet challenges.

The effect of executive function on adherence with a cardiac secondary prevention program and its interaction with an incentive-based intervention. Prev Med 2019; 128:105865. [PMID: 31662210 PMCID: PMC6939881 DOI: 10.1016/j.ypmed.2019.105865] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 09/20/2019] [Accepted: 10/11/2019] [Indexed: 12/29/2022]
Abstract
Participation in secondary prevention programs such as cardiac rehabilitation (CR) reduces morbidity, mortality, and hospitalizations while improving quality of life. Executive function (EF) is a complex set of cognitive abilities that control and regulate behavior. EF predicts many health-related behaviors, but how EF interacts with interventions to improve treatment adherence is not well understood. The objective of this study is to examine if EF predicts CR treatment adherence and how EF interacts with an intervention to improve adherence. Data were collected from 2013 to 2018 in Vermont, USA. 130 Medicaid-enrolled individuals who had experienced a qualifying cardiac event were enrolled in a controlled clinical trial and randomized 1:1 to receive financial incentives for completing secondary prevention sessions or to usual care. In this secondary analysis, effects of EF on CR adherence (defined as completing ≥30/36 sessions) were examined in 112 participants (57 usual care, 55 intervention) who completed an EF battery. Delay-discounting, a measure of impulsivity, predicted CR adherence (p = 0.01) and interacted with the incentive intervention, such that those who exhibited greater discounting of future rewards benefitted more from the intervention than those who discounted less (F(1, 104) = 5.23, p = 0.02). Better cognitive flexibility, measured with the trail-making-task, also predicted CR adherence (p = 0.02). While EF has been associated with adherence to a variety of treatment regimens, this interaction between an incentive-based intervention to promote treatment adherence and EF is novel. This work illustrates the value of considering individual differences in EF when designing and implementing interventions to promote health-related behavior change.

Abstract
The goal of this article is to introduce readers to theories, tools, and evidence from the field of neuroeconomics and to describe how health psychology and neuroeconomics can be mutually informative in the study of preventative health behaviors. Preventative health behavior here refers to both individual actions that impact one's health (e.g., exercise) and broader behavioral patterns, such as those captured in personality constructs. Although neuroeconomic researchers have begun to incorporate health-relevant behaviors into their studies, the full potential of this research to inform preventative health models is as yet unrealized. What is needed to "translate up" is the unification of rich theoretical content from health psychology with investigations by neuroeconomic researchers of the decision-making process during health-relevant choices. We identify choice as a central, shared feature across models of preventative health behavior that can serve as an inroad for neuroeconomics to contribute to existing models and highlight commonalities that might not otherwise be apparent. A central premise of our argument is that, because health decisions are nearly always multiply determined, a more precise and mechanistic understanding of how choices are made is an important but understudied topic in health psychology. A partnership between health psychologists and neuroeconomic researchers can yield valuable insights into how preventative health choice is made and to identify targets and methods for intervention.

Abstract
This study was part of monitoring an intervention aimed at developing a general practitioner cluster (GPC) model of primary healthcare (PHC) and testing its effectiveness in delivering preventive services integrated into the PHC system. The aim was to demonstrate whether GPC operation could increase the percentage of drugs actually dispensed. Using national reference data of the National Health Insurance Fund for each anatomical-therapeutic chemical classification ATC group of drugs, dispensed-to-prescribed ratios standardized (sDPR) for age, sex, and exemption certificate were calculated during the first quarter of 2012 (before-intervention) and the third quarter of 2015 (post-intervention). The after-to-before ratios of the sDPR as the relative dispensing ratio (RDR) were calculated to describe the impact of the intervention program. The general medication adherence increased significantly in the intervention area (RDR = 1.064; 95% confidence interval (CI): 1.054-1.073). The most significant changes were observed for cardiovascular system drugs (RDR = 1.062; 95% CI: 1.048-1.077) and for alimentary tract and metabolism-specific drugs (RDR = 1.072; 95% CI: 1.049-1.097). The integration of preventive services into a PHC without any specific medication adherence-increasing activities is beneficial for medication adherence, especially among patients with cardiovascular, alimentary tract, and metabolic disorders. Monitoring the percentage of drugs actually dispensed is a useful element of PHC-oriented intervention evaluation frames.

Abstract
The United States lags far behind other industrialized countries on major markers of population health. Population health experts identify unhealthy behavior patterns (e.g., cigarette smoking, other substance use disorders, physical inactivity and poor food choices, nonadherence with recommended medical regimens) as the largest contributor to the status quo. Because these risk behaviors are overrepresented in socioeconomically disadvantaged and other vulnerable populations, they also increase health disparities. Hence, identifying evidence-based strategies to promote and sustain health-related behavior change is critical to improving U.S. population health. In this report, we review research demonstrating the efficacy of voucher-based contingency management delivered alone or in combination with other interventions for treating substance use disorders and other health-related behavior problems. The efficacy supporting these interventions is robust and discernible at the level of controlled randomized clinical trials and meta-analyses. Unfortunately, these evidence-based interventions are being underutilized in routine clinical care for substance use disorders, although they are used broadly in private-sector wellness programs and international programs to reduce chronic poverty. This report reviews the evidence supporting the efficacy of voucher-based contingency management using projects developed at the University of Vermont as exemplars and discusses dissemination of the model to public and private sector efforts to improve individual and population health.

Abstract
BACKGROUND Competitions might encourage people to undertake and/or reinforce behaviour change, including smoking cessation. Competitions involve individuals or groups having the opportunity to win a prize following successful cessation, either through direct competition or by entry into a lottery or raffle. OBJECTIVES To determine whether competitions lead to higher long-term smoking quit rates. We also aimed to examine the impact on the population, the costs, and the unintended consequences of smoking cessation competitions. SEARCH METHODS This review has merged two previous Cochrane reviews. Here we include studies testing competitions from the reviews 'Competitions and incentives for smoking cessation' and 'Quit & Win interventions for smoking cessation'. We updated the evidence by searching the Cochrane Tobacco Addiction Group Specialized Register in June 2018. SELECTION CRITERIA We considered randomized controlled trials (RCTs), allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures in which participants were assigned to interventions by the investigators. Participants were smokers, of any age and gender, in any setting. Eligible interventions were contests, competitions, lotteries, and raffles, to reward cessation and continuous abstinence in smoking cessation programmes. DATA COLLECTION AND ANALYSIS For this update, data from new studies were extracted independently by two review authors. The primary outcome measure was abstinence from smoking at least six months from the start of the intervention. We performed meta-analyses to pool study effects where suitable data were available and where the effect of the competition component could be separated from that of other intervention components, and report other findings narratively. MAIN RESULTS Twenty studies met our inclusion criteria. Five investigated performance-based reward, where groups of smokers competed against each other to win a prize (N = 915). The remaining 15 used performance-based eligibility, where cessation resulted in entry into a prize draw (N = 10,580). Five of these used Quit & Win contests (N = 4282), of which three were population-level interventions. Fourteen studies were RCTs, and the remainder quasi-randomized or controlled trials. Six had suitable abstinence data for a meta-analysis, which did not show evidence of effectiveness of performance-based eligibility interventions (risk ratio (RR) 1.16, 95% confidence interval (CI) 0.77 to 1.74, N = 3201, I2 = 57%). No trials that used performance-based rewards found a beneficial effect of the intervention on long-term quit rates.The three population-level Quit & Win studies found higher smoking cessation rates in the intervention group (4% to 16.9%) than the control group at long-term follow-up, but none were RCTs and all had important between-group differences in baseline characteristics. These studies suggested that fewer than one in 500 smokers would quit because of the contest.Reported unintended consequences in all sets of studies generally related to discrepancies between self-reported smoking status and biochemically-verified smoking status. More serious adverse events were not attributed to the competition intervention.Using the GRADE system we rated the overall quality of the evidence for smoking cessation as 'very low', because of the high and unclear risk of bias associated with the included studies, substantial clinical and methodological heterogeneity, and the limited population investigated. AUTHORS' CONCLUSIONS At present, it is impossible to draw any firm conclusions about the effectiveness, or a lack of it, of smoking cessation competitions. This is due to a lack of well-designed comparative studies. Smoking cessation competitions have not been shown to enhance long-term cessation rates. The limited evidence suggesting that population-based Quit & Win contests at local and regional level might deliver quit rates above baseline community rates has not been tested adequately using rigorous study designs. It is also unclear whether the value or frequency of possible cash reward schedules influence the success of competitions. Future studies should be designed to compensate for the substantial biases in the current evidence base.

Pituitary Adenylate Cyclase-Activating Peptide (PACAP) Signaling and the Dark Side of Addiction. J Mol Neurosci 2018; 68:453-464. [PMID: 30074172 DOI: 10.1007/s12031-018-1147-6] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Accepted: 07/27/2018] [Indexed: 12/15/2022]
Abstract
While addiction to drugs of abuse represents a significant health problem worldwide, the behavioral and neural mechanisms that underlie addiction and relapse are largely unclear. The concept of the dark side of addiction, developed and explored by George Koob and colleagues, describes a systematic decrease in reward-related processing following drug self-administration and subsequent recruitment of anti-reward (i.e., stress) systems. Indeed, the activation of central nervous system (CNS) stress-response systems by drugs of abuse is contributory not only to mood and anxiety-related disorders but critical to both the maintenance of addiction and relapse following abstinence. In both human and animal studies, compounds that activate the bed nucleus of the stria terminalis (BNST) have roles in stress-related behaviors and addiction processes. The activation of pituitary adenylate cyclase-activating peptide (PACAP) systems in the BNST mediates many consequences of chronic stressor exposure that may engage in part downstream corticotropin-releasing hormone (CRH) signaling. Similar to footshock stress, the BNST administration of PACAP or the PAC1 receptor-specific agonist maxadilan can facilitate relapse following extinction of cocaine-seeking behavior. Further, in the same paradigm, the footshock-induced relapse could be attenuated following BNST pretreatment with PAC1 receptor antagonist PACAP6-38, implicating PACAP systems as critical components underlying stress-induced reinstatement. In congruence with previous work, the PAC1 receptor internalization and endosomal MEK/ERK signaling appear contributory mechanisms to the addiction processes. The studies offer new insights and approaches to addiction and relapse therapeutics.

Pituitary Adenylate Cyclase-Activating Peptide in the Bed Nucleus of the Stria Terminalis Mediates Stress-Induced Reinstatement of Cocaine Seeking in Rats. Neuropsychopharmacology 2018; 43:978-986. [PMID: 28656976 PMCID: PMC5854788 DOI: 10.1038/npp.2017.135] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2017] [Revised: 05/20/2017] [Accepted: 06/22/2017] [Indexed: 12/12/2022]
Abstract
Stressors often contribute to difficulties in maintaining behavior change following a period of abstinence, and may play a significant role in drug relapse. The activation of pituitary adenylate cyclase-activating peptide (PACAP) systems in the bed nucleus of the stria terminalis (BNST) mediates many consequences of chronic stressor exposure. Here we ask whether PACAP is also involved in producing reinstatement in a model of stress-induced relapse to drug taking. Rats self-administered cocaine for 1 h daily over 10 days that was followed by 20 days of extinction training in which lever pressing no longer produced cocaine. In experiment 1, quantitative PCR (qPCR) was performed at several stages to determine transcript levels of PACAP and corresponding receptors. Reinstatement of cocaine seeking was then tested after footshock exposure in different groups of rats that were pretreated with vehicle solution, a PAC1 receptor antagonist (experiment 2), or a PACAP agonist (experiment 3) without footshock. In experiment 1, cocaine self-administration increased BNST PACAP transcript levels similar to what we have previously reported with chronic stress. In experiment 2, intra-BNST infusions of the PAC1/VPAC2 antagonist, PACAP 6-38, prevented footshock-induced reinstatement of extinguished cocaine seeking. In experiment 3, intra-BNST PACAP infusion reinstated previously extinguished cocaine-seeking behavior in the absence of footshock. Cocaine self-administration elevated BNST PACAP, and BNST PACAP receptor activation was necessary and sufficient for stress-induced reinstatement of cocaine seeking. These data suggest that BNST PACAP systems may be viable targets for relapse prevention.

Abstract
A challenge for implementing DOHaD-defined health promotion is how to engage the at-risk population. The WHO Health Promoting School (HPS) model has proven success engaging youth and improving health behaviors. Hence, we introduced DOHaD concepts to 151 pupils aged 12–15 years in three HPS programs in rural Uganda, inquired what factors would make DOHaD-related health promotion resonate with them, and discussed how they recommended making learning about DOHaD acceptable to youth. Economic factors were judged the most compelling; with nutrition and responsive care elements next in importance. Suggested approaches included: teach how good health is beneficial, what works and why, and give tools to use to achieve it, and make information positive rather than linked to later harm. Involve youth in making DOHaD learning happen, make being a parent sound interesting, and include issues meaningful to boys. These are the first data from youth charged with addressing their engagement in the DOHaD agenda.

Abstract
Substantial reductions in U.S. cigarette smoking and associated chronic diseases over the past 50 years have benefited health. Unfortunately, those reductions have distributed unevenly throughout the population. Smoking remains prevalent and even increasing among certain vulnerable populations: economically disadvantaged groups, those with other substance-use disorders or mental illness, certain ethnic and racial minorities, and gender and sexual minorities. Moreover, other unhealthy behavior patterns (physical inactivity, unhealthy food choices, risky sexual behavior, poor adherence to medical preventive regimens) and associated chronic diseases are also overrepresented in many of these same populations. Disparities in unhealthy behavior patterns contribute to health disparities and escalating health care costs, underscoring the need for more effective behavior-change strategies. This report reviews research on the efficacy of financial incentives for reducing smoking in vulnerable populations, while also touching on applications of that behavior-change strategy for promoting other health-related behavior changes in vulnerable populations.

Abstract
Health-related behaviors such as tobacco, alcohol and other substance use, poor diet and physical inactivity, and risky sexual practices are important targets for research and intervention. Health-related behaviors are especially pertinent targets in the United States, which lags behind most other developed nations on common markers of population health. In this essay we examine the application of behavioral economics, a scientific discipline that represents the intersection of economics and psychology, to the study and promotion of health-related behavior change. More specifically, we review what we consider to be some core dimensions of this discipline when applied to the study health-related behavior change. Behavioral economics (1) provides novel conceptual systems to inform scientific understanding of health behaviors, (2) translates scientific understanding into practical and effective behavior-change interventions, (3) leverages varied aspects of behavior change beyond increases or decreases in frequency, (4) recognizes and exploits trans-disease processes and interventions, and (5) leverages technology in efforts to maximize efficacy, cost effectiveness, and reach. These dimensions are overviewed and their implications for the future of the field discussed.

Abstract
PURPOSE Cardiac rehabilitation (CR) improves medical outcomes after myocardial infarction or coronary revascularization. Lower socioeconomic status (SES) patients are less likely to participate in and complete CR. The aim of this study was to test whether financial incentives may increase participation and adherence to CR among lower-SES patients. METHODS Patients eligible to participate in CR with Medicaid insurance coverage were approached for inclusion. Patients were placed on an escalating incentive schedule of financial incentives contingent upon CR attendance. CR participation was compared to a usual care group of 101 Medicaid patients eligible for CR in the 18months prior to the study. Attendance (participating in ≥one CR sessions) and adherence (sessions completed out of 36) were compared between groups. The study was conducted in Vermont, USA, 2013-2015. RESULTS Of 13 patients approached to be in the study and receive incentives, 10 (77%) agreed to participate. All 10 patients completed at least one session of CR, significantly greater than the 25/101 (25%) in the control condition (p<0.001). Of patients in both groups who attended at least one session of CR, adherence was higher in the intervention group (average of 31.1 sessions completed vs. 13.6 in the control group, p<0.001). CR completion rates were also higher during the intervention with 8 of 10 (80%) intervention patients completing all 36 sessions compared to only 2 of 25 (8%) control patients (p<0.001). CONCLUSIONS Financial incentives may be an efficacious strategy for increasing CR participation and adherence among Medicaid patients.

Effectiveness and cost-effectiveness of a physical activity loyalty scheme for behaviour change maintenance: a cluster randomised controlled trial. BMC Public Health 2016; 16:618.

Abstract
BACKGROUND Increasing physical activity in the workplace can provide employee physical and mental health benefits, and employer economic benefits through reduced absenteeism and increased productivity. The workplace is an opportune setting to encourage habitual activity. However, there is limited evidence on effective behaviour change interventions that lead to maintained physical activity. This study aims to address this gap and help build the necessary evidence base for effective, and cost-effective, workplace interventions. METHODS/DESIGN This cluster randomised control trial will recruit 776 office-based employees from public sector organisations in Belfast and Lisburn city centres, Northern Ireland. Participants will be randomly allocated by cluster to either the Intervention Group or Control Group (waiting list control). The 6-month intervention consists of rewards (retail vouchers, based on similar principles to high street loyalty cards), feedback and other evidence-based behaviour change techniques. Sensors situated in the vicinity of participating workplaces will promote and monitor minutes of physical activity undertaken by participants. Both groups will complete all outcome measures. The primary outcome is steps per day recorded using a pedometer (Yamax Digiwalker CW-701) for 7 consecutive days at baseline, 6, 12 and 18 months. Secondary outcomes include health, mental wellbeing, quality of life, work absenteeism and presenteeism, and use of healthcare resources. Process measures will assess intervention "dose", website usage, and intervention fidelity. An economic evaluation will be conducted from the National Health Service, employer and retailer perspective using both a cost-utility and cost-effectiveness framework. The inclusion of a discrete choice experiment will further generate values for a cost-benefit analysis. Participant focus groups will explore who the intervention worked for and why, and interviews with retailers will elucidate their views on the sustainability of a public health focused loyalty card scheme. DISCUSSION The study is designed to maximise the potential for roll-out in similar settings, by engaging the public sector and business community in designing and delivering the intervention. We have developed a sustainable business model using a 'points' based loyalty platform, whereby local businesses 'sponsor' the incentive (retail vouchers) in return for increased footfall to their business.

Abstract
Use of technology (e.g., Internet, cell phones) to allow remote implementation of incentives interventions for health-related behavior change is growing. To our knowledge, there has yet to be a systematic review of this literature reported. The present report provides a systematic review of the controlled studies where technology was used to remotely implement financial incentive interventions targeting substance use and other health behaviors published between 2004 and 2015. For inclusion in the review, studies had to use technology to remotely accomplish one of the following two aims alone or in combination: (a) monitor the target behavior, or (b) deliver incentives for achieving the target goal. Studies also had to examine financial incentives (e.g., cash, vouchers) for health-related behavior change, be published in peer-reviewed journals, and include a research design that allowed evaluation of the efficacy of the incentive intervention relative to another condition (e.g., non-contingent incentives, treatment as usual). Of the 39 reports that met inclusion criteria, 18 targeted substance use, 10 targeted medication adherence or home-based health monitoring, and 11 targeted diet, exercise, or weight loss. All 39 (100%) studies used technology to facilitate remote monitoring of the target behavior, and 26 (66.7%) studies also incorporated technology in the remote delivery of incentives. Statistically significant intervention effects were reported in 71% of studies reviewed. Overall, the results offer substantial support for the efficacy of remotely implemented incentive interventions for health-related behavior change, which have the potential to increase the cost-effectiveness and reach of this treatment approach.

Abstract
Smoking during pregnancy is a leading preventable cause of poor pregnancy outcomes and immediate and longer-term adverse health outcomes among exposed offspring. Developing more effective smoking-cessation interventions for pregnant women has been a public-health priority for more than thirty years. We review developments over the past three years (2012-15) on the use of financial incentives to promote smoking cessation among pregnant women. We searched the literature for reports on primary and secondary analyses and reviews of controlled trials on this topic published in peer-reviewed journals using the search engine PubMed, reviewed bibliographies of published articles, and consulted expert colleagues. The search revealed several important developments, with the following three being especially noteworthy. First, the review identified four new randomized controlled trials, three of which further supported the efficacy of this treatment approach. One of the three trials supporting efficacy also included the first econometric analysis of this treatment approach showing financial incentives with pregnant smokers to be highly cost-effective. Second, two Cochrane reviews were published during this 3-year period covering the more recent and earlier efficacy trials. Meta-analyses in both reviews supported the efficacy of the approach. Lastly, the first effectiveness trial was reported demonstrating that financial incentives increased abstinence rates above control levels when implemented by obstetrical clinic staff in a large urban hospital working with community tobacco interventionists. Overall, there is a growing and compelling body of evidence supporting the efficacy and cost-effectiveness of financial incentives for smoking cessation among pregnant women.

Abstract
Research in the general population of smokers indicates that across various measures of nicotine dependence, time to first cigarette (TTFC) is the strongest single-item predictor of quitting success. Whether those findings generalize to pregnant smokers is unclear. To investigate this matter, we compared TTFC with cigarettes per day (CPD) and the Heaviness of Smoking Index (HSI; Kozlowski, Porter, Orleans, Pope, & Heatherton, 1994) in predicting late-pregnancy abstinence among 289 pregnant women enrolled in 4 smoking-cessation trials assessing the efficacy of financial incentives. Logistic regression was used to compare predictors, with model fit measured using the c statistic (range = 0.5, poor prediction to 1.0, perfect prediction). In simple regressions, model fit was comparable across the 3 measures although strongest for CPD alone (c = 0.70, 0.68, 0.66 for CPD, HSI, and TTFC, respectively). In a stepwise multiple regression, treatment was entered first (c = 0.67), then CPD (c = 0.77), quit attempts prepregnancy (c = .81), TTFC (c = .82), and quit attempts during pregnancy (c = .83). We saw no evidence supporting TTFC as the optimal predictor of quitting among pregnant smokers. Instead, the evidence supported using CPD and TTFC together or CPD alone if using only a single predictor.

Abstract
HIV risk remains high among Cambodian female entertainment and sex workers, driven by amphetamine-type substance use and sexual risk. Conditional cash transfer is an evidence-based approach to reduce stimulant use and optimize HIV/AIDS prevention, but questions remain regarding implementation in resource-limited settings. We conducted formative qualitative research to enhance acceptability of a conditional cash transfer intervention aimed at reducing amphetamine-type substance use and HIV risk among female entertainment/sex workers and inform implementation as part of a large cluster randomized trial. We conducted in-depth interviews with 30 female entertainment/sex workers. Interviews were digitally recorded and conducted and transcribed in Khmer. English transcripts were read for emerging themes and an initial coding scheme was developed. Data were coded using open and axial coding to clarify and consolidate initial themes. While most participants expressed enthusiasm for the intervention, financial and transportation issues emerged as key barriers to participation. The proposed incentive of USD$1 per screen was regarded as unacceptable and participants identified a need for transportation assistance. Participants also expressed concerns about directly observed urine specimen collection. Finally, while most participants found the 4-week aftercare program acceptable, the need for enjoyable as well as educational content was emphasized. Revisions to the protocol taking these data into account were made to optimize the acceptability of the intervention and the implementation of the trial. Findings identified key concerns and preferences that were taken into account in the final trial protocol. In particular, financial and transportation issues were identified as critical barriers to participation, with the potential to impact both intervention uptake and trial feasibility. Results demonstrate the value of formative qualitative research for clinical trial planning and implementation, particularly in settings where little is known about acceptability of interventions or willingness to participate.

Development of immunity following financial incentives for hepatitis B vaccination among people who inject drugs: A randomized controlled trial. J Clin Virol 2015; 74:66-72.

Abstract
BACKGROUND People who inject drugs (PWID) are at risk of hepatitis B virus (HBV) but have low rates of vaccination completion. The provision of modest financial incentives increases vaccination schedule completion, but their association with serological protection has yet to be determined. OBJECTIVE To investigate factors associated with vaccine-induced immunity among a sample of PWID randomly allocated to receive AUD$30 cash following receipt of doses two and three ('incentive condition') or standard care ('control condition') using an accelerated 3-dose (0,7,21 days) HBV vaccination schedule. STUDY DESIGN A randomised controlled trial among PWID attending two inner-city health services and a field site in Sydney, Australia, assessing vaccine-induced immunity measured by hepatitis B surface antibodies (HBsAb ≥ 10 mIU/ml) at 12 weeks. The cost of the financial incentives and the provision of the vaccine program are also reported. RESULTS Just over three-quarters of participants - 107/139 (77%)--completed the vaccination schedule and 79/139 (57%) were HBsAb ≥ 10 mIU/ml at 12 weeks. Vaccine series completion was the only variable significantly associated with vaccine-induced immunity in univariate analysis (62% vs 41%, p<0.035) but was not significant in multivariate analysis. There was no statistically discernible association between group allocation and series completion (62% vs 53%). The mean costs were AUD$150.5, (95% confidence interval [CI]: 142.7-158.3) and AUD$76.9 (95% CI: 72.6-81.3) for the intervention and control groups respectively. CONCLUSION Despite increasing HBV vaccination completion, provision of financial incentives was not associated with enhanced serological protection. Further research into factors which affect response rates and the optimal vaccination regimen and incentive schemes for this population are needed.

Abstract
INTRODUCTION Financial incentives are effective for smoking cessation during pregnancy. Public opinion is important for successful dissemination of this approach from research into clinical practice. We developed a brief information-based intervention to improve public acceptability. METHODS We recruited 166 adult participants (54.2% females [6.7% pregnant], 25.3% smokers, mean age 32.4 years [SD, 9.9]) currently living the United States from Amazon Mechanical Turk. They were randomized to either intervention (N = 84) or control (N = 82). The control group read educational materials on car safety for pregnant women and young children. The intervention group read educational materials on the rationale behind using financial incentives for smoking cessation during pregnancy. Key outcomes were 11 opinion items regarding whether using financial incentives to help pregnant smokers to quit is a good idea; its effectiveness, fairness, cost, health benefits, and saved healthcare cost; and pregnant women's responsibility and difficulty of quitting smoking. RESULTS Intervention and control groups had similar pretest opinion on using financial incentives for smoking cessation during pregnancy. All 11 mean opinion scores significantly increased in the intervention group, but remained stable in the control group. After the intervention, 27.7% more of participants (from 62.6% to 90.3%; P value < .001) in the intervention group and only 4.8% more (from 64.6% to 69.4%; P value = .557) in the control group agreed that "Paying pregnant women who smoke to quit smoking is a good idea" (interaction P value = .015). CONCLUSIONS Our low-cost information-based intervention has the potential to improve public acceptability of this efficacious approach to promoting smoking cessation during pregnancy. IMPLICATIONS In this sample of educated young adults, our low-cost information-based intervention substantially improved their acceptability of using financial incentives for smoking cessation during pregnancy. Our intervention can be used to gain public support before implementing this approach as a policy in the general population. One potential concern that needs to be further addressed by future intervention is unfairness of this smoking cessation approach to pregnant nonsmokers.

Social network recruitment for Yo Puedo: an innovative sexual health intervention in an underserved urban neighborhood—sample and design implications. J Prim Prev 2015; 36:51-64.

Abstract
Most existing evidence-based sexual health interventions focus on individual-level behavior, even though there is substantial evidence that highlights the influential role of social environments in shaping adolescents' behaviors and reproductive health outcomes. We developed Yo Puedo, a combined conditional cash transfer and life skills intervention for youth to promote educational attainment, job training, and reproductive health wellness that we then evaluated for feasibility among 162 youth aged 16-21 years in a predominantly Latino community in San Francisco, CA. The intervention targeted youth's social networks and involved recruitment and randomization of small social network clusters. In this paper we describe the design of the feasibility study and report participants' baseline characteristics. Furthermore, we examined the sample and design implications of recruiting social network clusters as the unit of randomization. Baseline data provide evidence that we successfully enrolled high risk youth using a social network recruitment approach in community and school-based settings. Nearly all participants (95%) were high risk for adverse educational and reproductive health outcomes based on multiple measures of low socioeconomic status (81%) and/or reported high risk behaviors (e.g., gang affiliation, past pregnancy, recent unprotected sex, frequent substance use; 62%). We achieved variability in the study sample through heterogeneity in recruitment of the index participants, whereas the individuals within the small social networks of close friends demonstrated substantial homogeneity across sociodemographic and risk profile characteristics. Social networks recruitment was feasible and yielded a sample of high risk youth willing to enroll in a randomized study to evaluate a novel sexual health intervention.

Abstract
We examined whether impulsiveness moderates response to financial incentives for cessation among pregnant smokers. Participants were randomized to receive financial incentives delivered contingent on smoking abstinence or to a control condition wherein incentives were delivered independent of smoking status. The study was conducted in two steps: First, we examined associations between baseline impulsiveness and abstinence at late pregnancy and 24-weeks-postpartum as part of a planned prospective study of this topic using data from a recently completed, randomized controlled clinical trial (N = 118). Next, to increase statistical power, we conducted a second analysis collapsing results across that recent trial and two prior trials involving the same study conditions (N = 236). Impulsivity was assessed using a delay discounting (DD) of hypothetical monetary rewards task in all three trials and Barratt Impulsiveness Scale (BIS) in the most recent trial. Neither DD nor BIS predicted smoking status in the single or combined trials. Receiving abstinence-contingent incentives, lower baseline smoking rate, and a history of quit attempts prepregnancy predicted greater odds of antepartum abstinence across the single and combined trials. No variable predicted postpartum abstinence across the single and combined trials, although a history of antepartum quit attempts and receiving abstinence-contingent incentives predicted in the single and combined trials, respectively. Overall, this study provides no evidence that impulsiveness as assessed by DD or BIS moderates response to this treatment approach while underscoring a substantial association of smoking rate and prior quit attempts with abstinence across the contingent incentives and control treatment conditions.

Abstract
This Special Issue of Preventive Medicine (PM) focuses on behavior change, health, and health disparities, topics of fundamental importance to improving population health in the U.S. and other industrialized countries. While the U.S. health care system and those of other industrialized countries were developed to manage infectious disease and acute illnesses, it is chronic health conditions that most need to be understood and managed in the 21st century. The evidence is clear that personal behavior patterns like cigarette smoking and physical inactivity/obesity are critically important proximal causes of chronic disease (cardiovascular disease, site-specific cancers, type-2 diabetes) and as such behavior change will need to be a key component of their management. As the outstanding contributions to this Special Issue illustrate, substantial headway is being made in advancing knowledge including developing effective prevention and treatment strategies, with cigarette smoking being an excellent example that change is possible. That said, cigarette smoking continues to be responsible for approximately 480,000 premature deaths annually in the U.S. alone and 5 million globally. So more needs to be done, especially in economically disadvantaged populations. The same certainly applies to the challenges of the obesity epidemic, which of course is a more recent problem and understandably efforts to curtail it are in earlier stages of development.

Abstract
Unhealthy behavior is responsible for much human disease, and a common goal of contemporary preventive medicine is therefore to encourage behavior change. However, while behavior change often seems easy in the short run, it can be difficult to sustain. This article provides a selective review of research from the basic learning and behavior laboratory that provides some insight into why. The research suggests that methods used to create behavior change (including extinction, counterconditioning, punishment, reinforcement of alternative behavior, and abstinence reinforcement) tend to inhibit, rather than erase, the original behavior. Importantly, the inhibition, and thus behavior change more generally, is often specific to the "context" in which it is learned. In support of this view, the article discusses a number of lapse and relapse phenomena that occur after behavior has been changed (renewal, spontaneous recovery, reinstatement, rapid reacquisition, and resurgence). The findings suggest that changing a behavior can be an inherently unstable and unsteady process; frequent lapses should be expected. In the long run, behavior-change therapies might benefit from paying attention to the context in which behavior change occurs.

Abstract
We propose that executive dysfunction is an important component relating to the socio-economic status gradient of select health behaviors. We review and find evidence supporting an SES gradient associated with (1) negative health behaviors (e.g., obesity, excessive use of alcohol, tobacco and other substances), and (2) executive dysfunction. Moreover, the evidence supports that stress and insufficient cognitive resources contribute to executive dysfunction and that executive dysfunction is evident among individuals who smoke cigarettes, are obese, abuse alcohol, and use illicit drugs. Collectively these data support the dual system model of cognitive control, referred to here as the Competing Neurobehavioral Decision Systems hypothesis. The implications of these relationships for intervention and social justice considerations are discussed.

Abstract
In the treatment of addictions, the gap between the availability of evidence-based therapies and their limited implementation in practice has not yet been bridged. Two empirically validated behavioral therapies, contingency management (CM) and cognitive behavioral therapy (CBT), exemplify this challenge. Both have a relatively strong level of empirical support but each has weak and uneven adoption in clinical practice. This review highlights examples of how barriers to their implementation in practice have been addressed systematically, using the Stage Model of Behavioral Therapies Development as an organizing framework. For CM, barriers such as cost and ideology have been addressed through the development of lower-cost and other adaptations to make it more community friendly. For CBT, barriers such as relative complexity, lack of trained providers, and need for supervision have been addressed via conversion to standardized computer-assisted versions that can serve as clinician extenders. Although these and other modifications have rendered both interventions more disseminable, diffusion of innovation remains a complex, often unpredictable process. The existing specialty addiction-treatment system may require significant reforms to fully implement CBT and CM, particularly greater focus on definable treatment goals and performance-based outcomes.

Abstract
We investigated three potential predictors (educational attainment, prepregnancy smoking rate, and delay discounting [DD]) of spontaneous quitting among pregnant smokers. These predictors were examined alone and in combination with other potential predictors using study-intake assessments from controlled clinical trials examining the efficacy of financial incentives for smoking cessation and relapse prevention. Data from 349 pregnant women (231 continuing smokers and 118 spontaneous quitters) recruited from the greater Burlington, VT, area contributed to this secondary analysis, including psychiatric/sociodemographic characteristics, smoking characteristics, and performance on a computerized DD task. Educational attainment, smoking rate, and DD values were each significant predictors of spontaneous quitting in univariate analyses. A model examining those three predictors together retained educational attainment as a main effect and revealed a significant interaction of DD and smoking rate (i.e., DD was a significant predictor at lower but not higher smoking rates). A final model considering all potential predictors, included education, the interaction of DD and smoking rate, and five additional predictors (i.e., stress ratings, the belief that smoking during pregnancy will "greatly harm my baby," age of smoking initiation, marital status, and prior quit attempts during pregnancy). The study presented here contributes new knowledge on predictors of spontaneous quitting among pregnant smokers with substantive practical implications for reducing smoking during pregnancy.

Abstract
PURPOSE Wide geographic variations in cardiac rehabilitation (CR) participation in the United States have been demonstrated but are not well understood. Socioeconomic factors such as educational attainment are robust predictors of many health-related behaviors, including smoking, obesity, physical activity, substance abuse, and cardiovascular disease. We investigated potential associations between state-level differences in educational attainment, other socioeconomic factors, CR program availability, and variations in CR participation. METHODS A retrospective database analysis was conducted using data from the US Census Bureau, the Centers for Disease Control and Prevention, and the 1997 Medicare database. The outcome of interest was CR participation rates by state, and predictors included state-level high school (HS) graduation rates (in 2001 and 1970), median household income, smoking rates, density of CR program (programs per square mile and per state population), sex and race ratios, and median age. RESULTS The relationship between HS graduation rates and CR participation by state was significant for both 2001 and 1970 (r = 0.64 and 0.44, respectively, P < .01). Adding the density of CR programs (per population) and income contributed significantly with a cumulative r value of 0.74 and 0.71 for the models using 2001 and 1970, respectively (Ps < .01). The amount of variance accounted for by each of the 3 variables differed between the 2000 and 1970 graduation rates, but both models were unaltered by including additional variables. CONCLUSIONS State-level HS graduation rates, CR programs expressed as programs per population, and median income were strongly associated with geographic variations in CR participation rates.

Abstract
This commentary addresses the efforts of Medicaid programs in several US states to employ financial incentives to increase healthy behavior among their beneficiaries. While these Medicaid incentive programs have been successful at boosting rates of less effortful behaviors, like semiannual dental visits, they have fallen short in promoting more complex behaviors, like smoking cessation, drug abstinence, and weight management. Incentives have been extensively studied as a treatment for substance use disorders for over 20years, with good success. We identify two variables shown by meta-analysis to moderate the efficacy of incentive interventions in substance abuse treatment, the immediacy of incentive delivery and size (or magnitude) of the incentive, that are lacking in current Medicaid incentive program. We also offer some guidance on how these moderating variables could be addressed within Medicaid programs. This is a critical time for such analysis, as more than 10 states are employing incentives in their Medicaid programs, and some are currently reevaluating their incentive strategies.

Abstract
Background Physical activity (PA) interventions typically include components or doses that are static across participants. Adaptive interventions are dynamic; components or doses change in response to short-term variations in participant's performance. Emerging theory and technologies make adaptive goal setting and feedback interventions feasible. Objective To test an adaptive intervention for PA based on Operant and Behavior Economic principles and a percentile-based algorithm. The adaptive intervention was hypothesized to result in greater increases in steps per day than the static intervention. Methods Participants (N = 20) were randomized to one of two 6-month treatments: 1) static intervention (SI) or 2) adaptive intervention (AI). Inactive overweight adults (85% women, M = 36.9±9.2 years, 35% non-white) in both groups received a pedometer, email and text message communication, brief health information, and biweekly motivational prompts. The AI group received daily step goals that adjusted up and down based on the percentile-rank algorithm and micro-incentives for goal attainment. This algorithm adjusted goals based on a moving window; an approach that responded to each individual's performance and ensured goals were always challenging but within participants' abilities. The SI group received a static 10,000 steps/day goal with incentives linked to uploading the pedometer's data. Results A random-effects repeated-measures model accounted for 180 repeated measures and autocorrelation. After adjusting for covariates, the treatment phase showed greater steps/day relative to the baseline phase (p<.001) and a group by study phase interaction was observed (p = .017). The SI group increased by 1,598 steps/day on average between baseline and treatment while the AI group increased by 2,728 steps/day on average between baseline and treatment; a significant between-group difference of 1,130 steps/day (Cohen's d = .74). Conclusions The adaptive intervention outperformed the static intervention for increasing PA. The adaptive goal and feedback algorithm is a “behavior change technology” that could be incorporated into mHealth technologies and scaled to reach large populations.

Abstract
BACKGROUND Recently both the UK and US governments have advocated the use of financial incentives to encourage healthier lifestyle choices but evidence for the cost-effectiveness of such interventions is lacking. Our aim was to perform a cost-effectiveness analysis (CEA) of a quasi-experimental trial, exploring the use of financial incentives to increase employee physical activity levels, from a healthcare and employer's perspective. METHODS Employees used a 'loyalty card' to objectively monitor their physical activity at work over 12 weeks. The Incentive Group (n=199) collected points and received rewards for minutes of physical activity completed. The No Incentive Group (n=207) self-monitored their physical activity only. Quality of life (QOL) and absenteeism were assessed at baseline and 6 months follow-up. QOL scores were also converted into productivity estimates using a validated algorithm. The additional costs of the Incentive Group were divided by the additional quality adjusted life years (QALYs) or productivity gained to calculate incremental cost effectiveness ratios (ICERs). Cost-effectiveness acceptability curves (CEACs) and population expected value of perfect information (EVPI) was used to characterize and value the uncertainty in our estimates. RESULTS The Incentive Group performed more physical activity over 12 weeks and by 6 months had achieved greater gains in QOL and productivity, although these mean differences were not statistically significant. The ICERs were £2,900/QALY and £2,700 per percentage increase in overall employee productivity. Whilst the confidence intervals surrounding these ICERs were wide, CEACs showed a high chance of the intervention being cost-effective at low willingness-to-pay (WTP) thresholds. CONCLUSIONS The Physical Activity Loyalty card (PAL) scheme is potentially cost-effective from both a healthcare and employer's perspective but further research is warranted to reduce uncertainty in our results. It is based on a sustainable "business model" which should become more cost-effective as it is delivered to more participants and can be adapted to suit other health behaviors and settings. This comes at a time when both UK and US governments are encouraging business involvement in tackling public health challenges.

A randomised controlled trial of financial incentives to increase hepatitis B vaccination completion among people who inject drugs in Australia. Prev Med 2013; 57:297-303.

Abstract
OBJECTIVE This study aimed to investigate the efficacy of modest financial incentives in increasing completion of an accelerated 3-dose hepatitis B virus (HBV) vaccination schedule (0, 7, 21days) among people who inject drugs (PWID). METHODS Randomised controlled trial. Participants were randomly allocated to receive $30 Australian Dollars cash following receipt of vaccine doses two and three ('incentive condition'), or standard care ('control condition'). Serologically confirmed HBV-susceptible PWID. Two inner-city health services and a field study site in Sydney, Australia. The primary outcome was completion of the vaccination series. Additional assessments included self-reported demographic, drug use and treatment, and risk-taking histories. RESULTS Compared to the control condition, significantly more participants in the incentive condition received all three vaccine doses, under intention-to-treat analyses (n=139; 87% versus 66%; p=.004); and within the specified window periods under per protocol analyses (n=107 received three vaccine doses; 92% versus 67%; p=.001). Multivariate analysis indicated that the incentive condition and longer injecting histories significantly increased the likelihood of series completion. Aboriginal/Torres Strait Islanders were significantly less likely to complete the series. CONCLUSIONS Modest financial incentives, per-dose, increased adherence to the accelerated HBV vaccination schedule among PWID. Results have implications for increasing HBV and, potentially, other vaccine-preventable infections, among PWID.

Kullgren JT, Williams GC, An LC. Patient-centered financial incentives for health: Can employers get change for their dollars? HEALTHCARE-THE JOURNAL OF DELIVERY SCIENCE AND INNOVATION 2013; 1:82-5. [PMID: 26249777 DOI: 10.1016/j.hjdsi.2013.08.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2013] [Revised: 08/17/2013] [Accepted: 08/22/2013] [Indexed: 11/18/2022]
Abstract
While employer-sponsored financial incentives for healthy behaviors have demonstrated the potential to promote short-term employee behavior change, the effectiveness of such incentives in promoting long-term health behavior change has often been disappointing. This paucity of sustained change could be explained by the many factors that shape employees' health behaviors, only some of which may be influenced by incentives. We discuss how employer-sponsored incentives for healthy behaviors could become more patient-centered, and thus perhaps more effective, by integrating insights from self-determination theory and health behavior theories, targeting employees' capacity for change, and using tailoring.

Hunter RF, Tully MA, Davis M, Stevenson M, Kee F. Physical activity loyalty cards for behavior change: a quasi-experimental study. Am J Prev Med 2013; 45:56-63. [PMID: 23790989 DOI: 10.1016/j.amepre.2013.02.022] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2012] [Revised: 12/12/2012] [Accepted: 02/25/2013] [Indexed: 11/16/2022]
Abstract
BACKGROUND Financial incentives have been advocated by the UK and U.S. governments to encourage adoption of healthy lifestyles. However, evidence to support the use of incentives for changing physical activity (PA) behavior is sparse. PURPOSE To investigate the effectiveness of financial incentives to increase PA in adults in the workplace. DESIGN Two-arm quasi-experimental design. SETTING/PARTICIPANTS Employees (n=406) in a workplace setting in Belfast, Northern Ireland, UK. INTERVENTION Using a loyalty card to collect points and earn rewards, participants (n=199) in the Incentive Group monitored their PA levels and received financial incentives (retail vouchers) for minutes of PA completed over the course of a 12-week intervention period. Participants (n=207) in the comparison group used their loyalty card to self-monitor their PA levels but were not able to earn points or obtain incentives (No Incentive Group). MAIN OUTCOME MEASURES The primary outcome was minutes of PA objectively measured using a novel PA tracking system at baseline (April 2011); Week 6 (June 2011); and Week 12 (July 2011). Other outcomes, including a self-report measure of PA, were collected at baseline, Week 12, and 6 months (October 2011). Data were analyzed in June 2012. RESULTS No significant differences between groups were found for primary or secondary outcomes at the 12-week and 6-month assessments. Participants in the Incentive Group recorded 17.52 minutes of PA/week (95% CI=12.49, 22.56) compared to 16.63 minutes/week (95% CI=11.76, 21.51) in the No Incentive Group at Week 12 (p=0.59). At 6 months, participants in the Incentive Group recorded 26.18 minutes of PA/week (95% CI=20.06, 32.29) compared to 24.00 minutes/week (95% CI=17.45, 30.54) in the No Incentive Group (p=0.45). CONCLUSIONS Financial incentives did not encourage participants to undertake more PA than self-monitoring PA. This study contributes to the evidence base and has important implications for increasing participation in physical activity and fostering links with the business sector.
