Paying women to quit smoking during pregnancy? Acceptability among pregnant women

Investigating the cost-effectiveness of three cessation interventions on a national scale using the Economics of Smoking in Pregnancy (ESIP) decision analytical model

AIM

To measure the cost-effectiveness of adding text message (TMB), exercise (EB) and abstinent-contingent financial incentive-based (CFIB) stop smoking interventions to standard smoking cessation support for pregnant women in England.

DESIGN

Modelling cost-effectiveness outcomes by separately adding three cessation interventions to standard cessation care offered to pregnant women in England. English National Health Service Stop Smoking Services (NHS SSS) statistics from 2019 to 2020 were used for estimating the base quit rate. Intervention effectiveness and cost data for interventions were taken from trial reports. Cost-effectiveness was derived using the economics of smoking in pregnancy (ESIP) model from a health service and personal social services perspective. Interventions were compared with each other as well as against standard cessation care.

SETTING

English NHS SSS.

PARTICIPANTS/CASES

A total of 13 799 pregnant women who accessed NHS SSS. Interventions and comparator; comparator: standard stop smoking support comprising behavioural intervention and an offer of nicotine replacement therapy (NRT). Three additive interventions were TMB, EB and CFIB.

MEASUREMENTS

Incremental cost-effectiveness ratios per quality-adjusted life-years gained for both mothers and offspring over their life-times; return on investment (ROI); and cost-effectiveness acceptability curves (CEACs).

FINDINGS

The addition of any of the interventions compared with standard care alone was preferred, but only significant for the addition of CFIB, with the CEAC suggesting an at least 90% chance of being favoured to standard care alone. When compared against each other CFIB appeared to yield the largest returns, but this was not significant. The estimated ROI for CFIB was £2 [95% confidence interval (CI) = £1-3] in health-care savings for every £1 spent by the NHS on the cessation intervention.

CONCLUSIONS

For a health system which currently provides behavioural support and an offer of nicotine replacement therapy as standard stop smoking support for pregnant women, the greatest economic gains would be provided by operating an abstinent-contingent financial incentives scheme alongside this.

Incentives for Smoking Cessation During Pregnancy: An Ethical Framework

Introduction

Smoking during pregnancy increases the risk of morbidity and mortality of the mother and child. The inability of the unborn child to protect itself, raises the social and academic responsibility to protect the child from the harmful effects of smoking. Interventions including rewards (incentives) for lifestyle changes are an upcoming trend and can encourage women to quit smoking. However, these incentives can, as we will argue, also have negative consequences, for example the restriction of personal autonomy and encouragement of smoking to become eligible for participation. To prevent these negative consequences, we developed an ethical framework that enables to assess and address unwanted consequences of incentive-based interventions whereby moral permissibility can be evaluated.

Aims and Methods

The possible adverse consequences of incentives were identified through an extensive literature search. Subsequently, we developed ethical criteria to identify these consequences based on the biomedical ethical principles of Beauchamp and Childress.

Results

Our framework consists of 12 criteria. These criteria concern (1) effectiveness, (2) support of a healthy lifestyle, (3) motivational for the target population, (4) stimulating unhealthy behavior, (5) negative attitudes, (6) personal autonomy, (7) intrinsic motivation, (8) privacy, (9) fairness, (10) allocation of incentives, (11) cost-effectiveness, and (12) health inequity. Based on these criteria, the moral permissibility of potential interventions can be evaluated.

Conclusions

Incentives for smoking cessation are a response to the responsibility to protect the unborn child. But these interventions might have possible adverse effects. This ethical framework aims to identify and address ethical pitfalls in order to avoid these adverse effects.

Implications

Although various interventions to promote smoking cessation during pregnancy exist, many women still smoke during pregnancy. Interventions using incentives for smoking cessation during pregnancy are a promising and upcoming trend but can have unwanted consequences. This ethical framework helps to identify and address ethical pitfalls in order to avoid these adverse effects.

It can be a practical tool in the development and evaluation of these interventions and in evaluating the moral permissibility of interventions using incentives for smoking cessation during pregnancy.

Perceptions of Financial Incentives for Smoking Cessation: A Survey of Smokers in a Country With an Endgame Goal

Introduction

Financial incentives can support smoking cessation, yet low acceptability may limit the wider implementation of such schemes. Few studies have examined how smokers view financial-incentive interventions aimed at reducing smoking prevalence.

Methods

We recruited a sample of 623 smokers from an internet panel to a survey assessing support for, and perceived effectiveness of, financial incentives for smoking cessation. We used descriptive statistics, plus logistic regression, to test associations between demographics and smoking, and support. We used qualitative content analysis to analyze open-ended responses to a question that invited respondents to comment on financial incentives.

Results

Financial incentives were supported by 38.4% of smokers; 42.2% did not support and 19.4% had no opinion. Support was higher among heavy (OR = 3.96, 95% CI = 2.39 to 6.58) and moderate smokers (OR = 1.68, 95% CI = 1.13 to 2.49), and those with a recent quit attempt (OR = 1.47, 95% CI = 1.04 to 2.07). Support was strongly associated with perceived effectiveness. A Government-funded reward-only scheme was seen as the most acceptable option (preferred by 26.6% of participants), followed by a Government-funded deposit-based scheme (20.6%); few respondents supported employer-funded schemes. Open-ended responses (n = 301) indicated three overarching themes expressing opposition to financial incentives: smokers' individual responsibility for quitting, concerns about abuse of an incentive scheme, and concerns about unfairness.

Conclusion

Even amongst those who would benefit from schemes designed to reward smokers for quitting, support for such schemes is muted, despite the evidence of their effectiveness. Media advocacy and health education could be used to increase the understanding of, and support for, financial incentives for smoking cessation.

Implications

Given the absolute effectiveness and cost effectiveness of financial-incentive schemes for smoking cessation amongst pregnant smokers and in workplaces, implementing such schemes at a national-level could help reduce overall smoking prevalence and contribute to endgame goals. Our study found that similar proportions of smokers supported and opposed financial-incentive schemes and suggests that much of the opposition was underpinned by information gaps, which could be addressed using education and media advocacy.

Public acceptability of financial incentives to reward pregnant smokers who quit smoking: a United Kingdom-France comparison

A substantial amount of research has been conducted on financial incentives to increase abstinence from smoking among pregnant smokers. If demonstrated to be effective, financial incentives could be proposed as part of health care interventions to help pregnant smokers quit. Public acceptability is important; as such interventions could be publicly funded. Concerns remain about the acceptability of these interventions in the general population. We aimed to assess the acceptability of financial incentives to reward pregnant smokers who stop smoking using a survey conducted in the UK and then subsequently in France, two developed countries with different cultural and social backgrounds. More French than British respondents agreed with financial incentives for rewarding quitting smoking during pregnancy, not smoking after delivery, keeping a smoke-free household, health service payment for meeting target and the maximum amount of the reward. However, fully adjusted models showed significant differences only for the two latter items. More British than French respondents were neutral toward financial incentives. Differences between the representative samples of French and British individuals demonstrate that implementation of financial incentive policies may not be transferable from one country to another.

Acceptability of financial incentives for maintenance of weight loss in mid-older adults: a mixed methods study

BACKGROUND

Health insurers worldwide implement financial incentive schemes to encourage health-related behaviours, including to facilitate weight loss. The maintenance of weight loss is a public health challenge, and as non-communicable diseases become more prevalent with increasing age, mid-older adults could benefit from programs which motivate weight loss maintenance. However, little is understood about their perceptions of using financial incentives to maintain weight loss.

METHODS

We used mixed methods to explore the attitudes and views of participants who had completed an Australian weight loss and lifestyle modification program offered to overweight and obese health insurance members with weight-related chronic diseases, about the acceptability and usefulness of different types of financial incentives to support weight loss maintenance. An online survey was completed by 130 respondents (mean age = 64 years); and a further 28 participants (mean age = 65 years) attended six focus groups.

RESULTS

Both independent samples of participants supported a formalised maintenance program. Online survey respondents reported that non-cash (85.2%) and cash (77%) incentives would be potentially motivating; but only 40.5% reported that deposit contracts would motivate weight loss maintenance. Results of in-depth discussions found overall low support for any type of financial incentive, but particularly deposit contracts and lotteries. Some participants expressed that improved health was of more value than a monetary incentive and that they felt personally responsible for their own health, which was at odds with the idea of financial incentives. Others suggested ongoing program and peer support as potentially useful for weight loss maintenance.

CONCLUSIONS

If financial incentives are considered for mid-older Australian adults in the health insurance setting, program planners will need to balance the discordance between participant beliefs about the individual responsibility for health and their desire for external supports to motivate and sustain weight loss maintenance.

Treatment Satisfaction in a Randomized Clinical Trial of mHealth Smoking Abstinence Reinforcement

The importance of patient satisfaction in modern healthcare is widely recognized, but research on satisfaction in the context of smoking cessation has not kept pace. The purpose of this study was to explore treatment satisfaction in a sample of smokers (N=84) randomized to one of two smoking cessation treatment interventions (mHealth reinforcement and mHealth monitoring) that used cell phone-based procedures to monitor smoking status in individuals' natural environments for 4 weeks. Starting on the target quit date, participants received usual care smoking cessation treatment consisting of 8 weeks of transdermal nicotine and 4 weeks of twice-weekly telephone counseling were also prompted 1 to 3 times daily (with exact number and timing not disclosed beforehand) to use a study cell phone and CO monitor to complete a CO self-test, video-record the process, and submit videos using multimedia messaging within 2 hours. mHealth reinforcement participants could earn prizes for smoking-negative on-time CO tests. A treatment satisfaction survey was completed at the end of the 4-week monitoring/reinforcement phase. Results indicate that participants overwhelmingly endorsed high levels of overall satisfaction in both conditions. Treatment adherence did not differ between conditions, but was positively associated with endorsing the highest satisfaction with help quitting with the intervention (p<.01 to .03). mHealth reinforcement was associated with increased longest duration of abstinence (p<.01). Controlling for relevant participant characteristics and treatment adherence, longest duration of abstinence robustly predicted highest satisfaction with help quitting and mediated the effect of treatment condition on that satisfaction. Further research on treatment satisfaction may aid the development of effective abstinence reinforcement and other smoking cessation interventions.

Benefits of Incentives for Breastfeeding and Smoking cessation in pregnancy (BIBS): a mixed-methods study to inform trial design

BACKGROUND

Smoking in pregnancy and/or not breastfeeding have considerable negative health outcomes for mother and baby.

AIM

To understand incentive mechanisms of action for smoking cessation in pregnancy and breastfeeding, develop a taxonomy and identify promising, acceptable and feasible interventions to inform trial design.

DESIGN

Evidence syntheses, primary qualitative survey, and discrete choice experiment (DCE) research using multidisciplinary, mixed methods. Two mother-and-baby groups in disadvantaged areas collaborated throughout.

SETTING

UK.

PARTICIPANTS

The qualitative study included 88 pregnant women/recent mothers/partners, 53 service providers, 24 experts/decision-makers and 63 conference attendees. The surveys included 1144 members of the general public and 497 health professionals. The DCE study included 320 women with a history of smoking.

METHODS

(1) Evidence syntheses: incentive effectiveness (including meta-analysis and effect size estimates), delivery processes, barriers to and facilitators of smoking cessation in pregnancy and/or breastfeeding, scoping review of incentives for lifestyle behaviours; (2) qualitative research: grounded theory to understand incentive mechanisms of action and a framework approach for trial design; (3) survey: multivariable ordered logit models; (4) DCE: conditional logit regression and the log-likelihood ratio test.

RESULTS

Out of 1469 smoking cessation and 5408 breastfeeding multicomponent studies identified, 23 smoking cessation and 19 breastfeeding studies were included in the review. Vouchers contingent on biochemically proven smoking cessation in pregnancy were effective, with a relative risk of 2.58 (95% confidence interval 1.63 to 4.07) compared with non-contingent incentives for participation (four studies, 344 participants). Effects continued until 3 months post partum. Inconclusive effects were found for breastfeeding incentives compared with no/smaller incentives (13 studies) but provider commitment contracts for breastfeeding show promise. Intervention intensity is a possible confounder. The acceptability of seven promising incentives was mixed. Women (for vouchers) and those with a lower level of education (except for breastfeeding incentives) were more likely to disagree. Those aged ≤ 44 years and ethnic minority groups were more likely to agree. Agreement was greatest for a free breast pump and least for vouchers for breastfeeding. Universal incentives were preferred to those targeting low-income women. Initial daily text/telephone support, a quitting pal, vouchers for > £20.00 per month and values up to £80.00 increase the likelihood of smoking cessation. Doctors disagreed with provider incentives. A 'ladder' logic model emerged through data synthesis and had face validity with service users. It combined an incentive typology and behaviour change taxonomy. Autonomy and well-being matter. Personal difficulties, emotions, socialising and attitudes of others are challenges to climbing a metaphorical 'ladder' towards smoking cessation and breastfeeding. Incentive interventions provide opportunity 'rungs' to help, including regular skilled flexible support, a pal, setting goals, monitoring and outcome verification. Individually tailored and non-judgemental continuity of care can bolster women's capabilities to succeed. Rigid, prescriptive interventions placing the onus on women to behave 'healthily' risk them feeling pressurised and failing. To avoid 'losing face', women may disengage.

LIMITATIONS

Included studies were heterogeneous and of variable quality, limiting the assessment of incentive effectiveness. No cost-effectiveness data were reported. In surveys, selection bias and confounding are possible. The validity and utility of the ladder logic model requires evaluation with more diverse samples of the target population.

CONCLUSIONS

Incentives provided with other tailored components show promise but reach is a concern. Formal evaluation is recommended. Collaborative service-user involvement is important.

Improving Public Acceptability of Using Financial Incentives for Smoking Cessation During Pregnancy: A Randomized Controlled Experiment

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.

Development of the Health Incentive Program Questionnaire (HIP-Q) in a cardiac rehabilitation population

The purpose of this study was to develop a questionnaire to facilitate the design of acceptable financial health incentive programs. A multiphase psychometric questionnaire development method was used. Theoretical and literature reviews and three focus groups generated a pool of content areas and items. New items were developed to ensure adequate content coverage. Field testing was conducted with a convenience sample of cardiac rehabilitation (CR) patients (n = 59) to establish face and construct validity (p = 0.021) and reliability (intraclass coefficients = 0.42–0.87). The final questionnaire is comprised of 23 items. This questionnaire builds on previous attempts to explore acceptability by sampling a wider range of instrumental and affective attitudes and by measuring the effect of program features on the likelihood of incentive program participation. Future research is now needed to examine whether tailoring incentives to preferences assessed by the questionnaire improves uptake and effectiveness.

Acceptability of financial incentives for breastfeeding: thematic analysis of readers' comments to UK online news reports

BACKGROUND

Whilst it is recommended that babies are breastfed exclusively for the first six months, many mothers do not maintain breastfeeding for this length of time. Previous research confirms that women and midwives value financial incentives for breastfeeding, but limited research has explored the wider acceptability of these interventions to the general public. This paper examines opinion towards financial incentives for breastfeeding using reader responses to UK on-line media coverage of a study undertaken in this area.

METHODS

This study used netnography to undertake a thematic analysis of 3,373 reader comments posted in response to thirteen articles, published in November 2013, which reported findings from a feasibility study of financial incentives for breastfeeding. All articles were published on one of six UK news websites that achieved a monthly audience of at least five million viewers across laptop and desktop computers and mobile devices during April-May 2013.

RESULTS

Nine analytical themes were identified, with a majority view that financial incentives for breastfeeding are unacceptable. These themes cover a range of opinions: from negligent parents unable to take responsibility for their own actions; through to psychologically vulnerable members of society who should be protected from coercion and manipulation; to capable and responsible women who can, and should be allowed to, make their own decisions. Many views focused on the immediate costs of the intervention, concluding that this was something that was currently unaffordable to fund (e.g. by the NHS). Others contrasted the value of the incentive against other 'costs' of breastfeeding. There was some consideration of the issue of cost-effectiveness and cost-saving, where the potential future benefit from initial investment was identified. Many commenters identified that financial incentives do not address the many structural and cultural barriers to breastfeeding.

CONCLUSIONS

Overall, those commenting on the on-line UK news articles viewed financial incentives for breastfeeding as unacceptable and that alternative, structural, interventions were likely to be more effective. Further consideration of how best to conduct internet-based qualitative research to elicit opinion towards public health issues is required.

Acceptability of financial incentives and penalties for encouraging uptake of healthy behaviours: focus groups

Background

There is evidence that financial incentive interventions, which include both financial rewards and also penalties, are effective in encouraging healthy behaviours. However, concerns about the acceptability of such interventions remain. We report on focus groups with a cross-section of adults from North East England exploring their acceptance of financial incentive interventions for encouraging healthy behaviours amongst adults. Such information should help guide the design and development of acceptable, and effective, financial incentive interventions.

Methods

Eight focus groups with a total of 74 adults were conducted between November 2013 and January 2014 in Newcastle upon Tyne, UK. Focus groups lasted approximately 60 minutes and explored factors that made financial incentives acceptable and unacceptable to participants, together with discussions on preferred formats for financial incentives. Verbatim transcripts were thematically coded and analysed in Nvivo 10.

Results

Participants largely distrusted health promoting financial incentives, with a concern that individuals may abuse such schemes. There was, however, evidence that health promoting financial incentives may be more acceptable if they are fair to all recipients and members of the public; if they are closely monitored and evaluated; if they are shown to be effective and cost-effective; and if clear health education is provided alongside health promoting financial incentives. There was also a preference for positive rewards rather than negative penalties, and for shopping vouchers rather than cash incentives.

Conclusions

This qualitative empirical research has highlighted clear suggestions on how to design health promoting financial incentives to maximise acceptability to the general public. It will also be important to determine the acceptability of health promoting financial incentives in a range of stakeholders, and in particular, those who fund such schemes, and policy-makers who are likely to be involved with the design, implementation and evaluation of health promoting financial incentive schemes.

Supporting pregnant Aboriginal and Torres Strait Islander women to quit smoking: views of antenatal care providers and pregnant indigenous women

To assess support for 12 potential smoking cessation strategies among pregnant Australian Indigenous women and their antenatal care providers. Cross-sectional surveys of staff and women in antenatal services providing care for Indigenous women in the Northern Territory and New South Wales, Australia. Respondents were asked to indicate the extent to which each of a list of possible strategies would be helpful in supporting pregnant Indigenous women to quit smoking. Current smokers (n = 121) were less positive about the potential effectiveness of most of the 12 strategies than the providers (n = 127). For example, family support was considered helpful by 64 % of smokers and 91 % of providers; between 56 and 62 % of smokers considered advice and support from midwives, doctors or Aboriginal Health Workers likely to be helpful, compared to 85-90 % of providers. Rewards for quitting were considered helpful by 63 % of smokers and 56 % of providers, with smokers rating them more highly and providers rating them lower, than most other strategies. Quitline was least popular for both. This study is the first to explore views of pregnant Australian Indigenous women and their antenatal care providers on strategies to support smoking cessation. It has identified strategies which are acceptable to both providers and Indigenous women, and therefore have potential for implementation in routine care. Further research to explore their feasibility in real world settings, uptake by pregnant women and actual impact on smoking outcomes is urgently needed given the high prevalence of smoking among pregnant Indigenous women.

Public acceptability of financial incentives for smoking cessation in pregnancy and breast feeding: a survey of the British public

OBJECTIVE

To survey public attitudes about incentives for smoking cessation in pregnancy and for breast feeding to inform trial design.

DESIGN

Cross-sectional survey.

SETTING AND PARTICIPANTS

British general public.

METHODS

Seven promising incentive strategies had been identified from evidence syntheses and qualitative interview data from service users and providers. These were shopping vouchers for: (1) validated smoking cessation in pregnancy and (2) after birth; (3) for a smoke-free home; (4) for proven breast feeding; (5) a free breast pump; (6) payments to health services for reaching smoking cessation in pregnancy targets and (7) breastfeeding targets. Ipsos MORI used area quota sampling and home-administered computer-assisted questionnaires, with randomised question order to assess agreement with different incentives (measured on a five-point scale). Demographic data and target behaviour experience were recorded. Analysis used multivariable ordered logit models.

RESULTS

Agreement with incentives was mixed (ranging from 34% to 46%) among a representative sample of 1144 British adults. Mean agreement score was highest for a free breast pump, and lowest for incentives for smoking abstinence after birth. More women disagreed with shopping vouchers than men. Those with lower levels of education disagreed more with smoking cessation incentives and a breast pump. Those aged 44 or under agreed more with all incentive strategies compared with those aged 65 and over, particularly provider targets for smoking cessation. Non-white ethnic groups agreed particularly with breastfeeding incentives. Current smokers with previous stop attempts and respondents who had breast fed children agreed with providing vouchers for the respective behaviours. Up to £40/month vouchers for behaviour change were acceptable (>85%).

CONCLUSIONS

Women and the less educated were more likely to disagree, but men and women of childbearing age to agree, with incentives designed for their benefit. Trials evaluating reach, impact on health inequalities and ethnic groups are required prior to implementing incentive interventions.

'Will walk for groceries': Acceptability of financial health incentives among Canadian cardiac rehabilitation patients

Financial health incentives, such as paying people to exercise, remain controversial despite widespread implementation. This focus group study explored the acceptability of incentives among a sample of Canadian cardiac rehabilitation (CR) patients (n = 15). Focus groups were conducted between March and April 2013 until further sampling ceased to produce new analytical concepts. A thematic analysis approach was adopted in analysing the data. Three broad themes emerged from the focus groups. First, ethical concerns were prominent. Half of participants disagreed with the incentive approach believing that it was unfair, unnecessary or a waste of limited resources. Second, ethical concerns were mitigated in considering a range of incentive features including type, size and source. Specifically, privately sponsored (not government funded) health-promoting voucher-based incentives (e.g., grocery or gym vouchers) were perceived to be highly acceptable. Third, if designed like this, then financial incentives were considered potentially effective in motivating behaviour change and in reducing economic barriers to exercise participation. Overall, the majority of participants welcomed incentives if ethical concerns were addressed through thoughtful incentive programme design. The results of this focus group study will inform the design of a financial health incentive feasibility RCT to promote post-CR programme exercise compliance in this population.

Gender differences in characteristics and outcomes of smokers diagnosed with psychosis participating in a smoking cessation intervention

While research has identified gender differences in characteristics and outcomes of smokers in the general population, no studies have examined this among smokers with psychosis. This study aimed to explore gender differences among 298 smokers with psychosis (schizophrenia, schizoaffective and bipolar affective disorder) participating in a smoking intervention study. Results revealed a general lack of gender differences on a range of variables for smokers with psychosis including reasons for smoking/quitting, readiness and motivation to quit, use of nicotine replacement therapy, and smoking outcomes including point prevalence or continuous abstinence, and there were no significant predictors of smoking reduction status according to gender at any of the follow-up time-points. The current study did find that female smokers with psychosis were significantly more likely than males to report that they smoked to prevent weight gain. Furthermore, the females reported significantly more reasons for quitting smoking and were more likely to be driven by extrinsic motivators to quit such as immediate reinforcement and social influence, compared to the male smokers with psychosis. Clinical implications include specifically focussing on weight issues and enhancing intrinsic motivation to quit smoking for female smokers with psychosis; and strengthening reasons for quitting among males with psychosis.

Acceptability of an Internet-based contingency management intervention for smoking cessation: views of smokers, nonsmokers, and healthcare professionals

The acceptability of an Internet-based contingency management (CM) intervention for cigarette smoking was evaluated in two experiments. In Experiment 1, 67 participants (46% female) completed an Internet-based CM intervention and then answered questions about the intervention. Experiment 2 assessed the acceptability of the intervention among potential treatment users who had never used the intervention, (smokers, n = 164, 52% female), nonsmokers (n = 166, 73% female), and health-care providers (n = 139, 63% female). Participants in Experiment 2 were randomly assigned to either watch a video describing the standard CM intervention (no-deposit group) or to watch a video about the standard intervention plus a deposit incentive (deposit group). Overall, results of both experiments indicated high acceptability across all dimensions of the intervention. In Experiment 1, 74% (n = 26 of participants in the treatment group) of participants said they would use it if they needed to quit, as well as 92% (n = 150 among smokers) of those in Experiment 2. Of the health-care providers, 81% (n = 113) reported that they would be very likely to recommend the intervention to patients. Participants in both experiments reported that monitoring their progress and earning vouchers were strengths of the intervention. The no-deposit group rated voucher earnings, cash earnings, and cost-effectiveness of the intervention higher than the deposit group. Health-care professionals did not differ in their ratings across video conditions. Overall, the results suggest that Internet-based CM is acceptable as a method to help people quit smoking.

An RCT protocol of varying financial incentive amounts for smoking cessation among pregnant women

Background

Smoking during pregnancy is harmful to the unborn child. Few smoking cessation interventions have been successfully incorporated into standard antenatal care. The main aim of this study is to determine the feasibility of a personal financial incentive scheme for encouraging smoking cessation among pregnant women.

Design

A pilot randomised control trial will be conducted to assess the feasibility and potential effectiveness of two varying financial incentives that increase incrementally in magnitude ($20 vs. $40AUD), compared to no incentive in reducing smoking in pregnant women attending an Australian public hospital antenatal clinic.

Method

Ninety (90) pregnant women who self-report smoking in the last 7 days and whose smoking status is biochemically verified, will be block randomised into one of three groups: a. No incentive control group (n=30), b. $20 incremental incentive group (n=30), and c. $40 incremental incentive group (n=30). Smoking status will be assessed via a self-report computer based survey in nine study sessions with saliva cotinine analysis used as biochemical validation. Women in the two incentive groups will be eligible to receive a cash reward at each of eight measurement points during pregnancy if 7-day smoking cessation is achieved. Cash rewards will increase incrementally for each period of smoking abstinence.

Discussion

Identifying strategies that are effective in reducing the number of women smoking during pregnancy and are easily adopted into standard antenatal practice is of utmost importance. A personal financial incentive scheme is a potential antenatal smoking cessation strategy that warrants further investigation.

Money as motivation to quit: a survey of a non-random Australian sample of socially disadvantaged smokers' views of the acceptability of cash incentives

OBJECTIVE

This study aimed to a) assess acceptability of personal financial incentives to socially disadvantaged smokers and non-smokers; b) examine factors associated with acceptability; and c) examine preferred levels of incentive amounts.

METHODS

A cross-sectional touch screen computer survey was conducted between February and October 2010 in New South Wales, Australia. Participants were clients experiencing financial or social hardship and receiving emergency welfare aid from a non-government social and community service organisation.

RESULTS

Of 383 participants (69% response rate), 46% believed personal financial incentives were an excellent/good idea, 47% believed personal financial incentives did more good than harm and 61% agreed they would motivate smokers to quit. High acceptability ratings were associated with participants being female, current smokers, living in low socioeconomic areas, experiencing smoking-induced deprivation, making a previous quit attempt and intending to quit in the next 6 months. When asked what amount of incentive they felt would be acceptable, 23% selected amounts between $50 and $500 AUD and 37% selected amounts over $500 AUD.

CONCLUSIONS

Given high smoking prevalence among socially disadvantaged groups and consequent health disparities, it is imperative novel methods of encouraging smoking cessation are explored and tested. This survey found financial incentives may be an acceptable method. Further research to understand all possible positive and negative effects is warranted.

Prenatal ablation of nicotinic receptor alpha7 cell lineages produces lumbosacral spina bifida the severity of which is modified by choline and nicotine exposure

Lumbosacral spina bifida is a common debilitating birth defect whose multiple causes are poorly understood. Here, we provide the first genetic delineation of cholinergic nicotinic receptor alpha7 (Chrna7) expression and link the ablation of the Chrna7 cell lineage to this condition in the mouse. Using homologous recombination, an IRES-Cre bi-cistronic cassette was introduced into the 3′ noncoding region of Chrna7 (Chrna7:Cre) for identifying cell lineages expressing this gene. This lineage first appears at embryonic day E9.0 in rhombomeres 3 and 5 of the neural tube and extends to cell subsets in most tissues by E14.5. Ablation of the Chrna7:Cre cell lineage in embryos from crosses with conditionally expressed attenuated diphtheria toxin results in precise developmental defects including omphalocele (89%) and open spina bifida (SB; 80%). We hypothesized that like humans, this defect would be modified by environmental compounds not only folic acid or choline but also nicotine. Prenatal chronic oral nicotine administration substantially worsened the defect to often include the rostral neural tube. In contrast, supplementation of the maternal diet with 2% choline decreased SB prevalence to 38% and dramatically reduced the defect severity. Folic acid supplementation only trended towards a reduced SB frequency. The omphalocele was unaffected by these interventions. These studies identify the Chrna7 cell lineage as participating in posterior neuropore closure and present a novel model of lower SB that can be substantially modified by the prenatal environment. © 2012 Wiley Periodicals, Inc.

The New York Times readers' opinions about paying people to take their medicine

BACKGROUND

There has been considerable interest in using financial incentives to help people improve their health. However, paying people to improve their health touches on strongly held views about personal responsibility.

METHOD

The New York Times printed two articles in June 2010 about patient financial incentives, which resulted in 394 comments from their online audience. The authors systematically analyzed those online responses to news media in order to understand the range of themes that were expressed regarding the use of financial incentives to improve health.

RESULTS

The New York Times online readers revealed a broad range of attitudes about paying individuals to be healthy. Many comments reflected disdain for financial incentives, describing them as "absurd" or "silly." Other comments reflected the notion that financial incentives reward individuals for being irresponsible toward their health. Many individuals communicated concerns that paying individuals for healthy behaviors may weaken their internal drive to be healthy. A smaller set of comments conveyed support for financial incentives, recognizing it as a small sum to pay to prevent or offset higher costs related to chronic diseases.

CONCLUSIONS

Although a measurable group of individuals supported financial incentives, most readers revealed negative perceptions of these approaches and an appeal for greater personal responsibility for individual health. Despite experimental success of financial incentives, negative perceptions may limit their public acceptability and uptake.
