Preferences of Cancer Survivors for Follow-Up Care: A Systematic Review of Discrete Choice Experiments.

Cancer survivors frequently encounter multiple challenges, including physical, psychological, social, emotional, and financial difficulties. These challenges significantly impact their quality of life and recovery process. This systematic review intends to delineate and assess the evidence gathered from discrete choice experiments, aiming to unravel the preferences of cancer survivors towards their follow-up care. A systematic literature review was conducted across PubMed, Web of Science, Embase, CINAHL, PsycINFO, CNKI, Wanfang, and SinoMed databases up to July 2024. Two reviewers independently conducted the screening, data extraction, and quality appraisal of the studies. The collected data were synthesized through a narrative approach. Additionally, semi-quantitative analyses were used to evaluate the frequency, importance, and significance of each attribute. Eight studies conducted across four countries were analyzed, yielding 41 distinct attributes grouped into eight main categories and 14 subcategories, further refined by subject matter. Despite the differences in payment systems between countries, the type of provider topped the list of preferences for cancer survivors' follow-up care. Next in preference was the contact modality. Service quality (comprehensive plans, personalized service, detailed information) was also valued. However, opinions diverged on continuity, additional support, and service frequency. The attributes of follow-up care preferences integrated in this review demonstrate a diverse range among cancer survivors. Generally, they prioritize skilled professionals, flexible contact modality, and other high-quality follow-up care elements. Future studies should analyze cancer survivors' preferences for follow-up care from the perspectives of different stakeholders, and further consider internal and external factors to ensure authentic decision making.

Patient Preferences for Surgical Treatments for Benign Prostatic Hyperplasia: A Discrete Choice Experiment

Purpose: When symptoms of benign prostatic hyperplasia cannot or can no longer be treated by conservative treatment options adequately, various surgical treatment options are available. Different risks and benefits are associated with each type of surgery; the optimal choice depends on the patient's preference. This study analyzes patients' preferences and investigates patient characteristics that might influence patient preferences in Germany. Materials and Methods: We conducted an online discrete choice experiment based on 9 treatment attributes related to risks (probability of ejaculatory dysfunction, permanent incontinence, needing surgery again, and erectile dysfunction) and efficacy (frequency of daytime and nighttime urination, urgency and duration of urination, and time until symptoms improve) of surgeries. To estimate preferences, we applied a mixed-logit model. Subgroup analyses based on patients' characteristics were conducted. Results: Three hundred thirty participants completed the discrete choice experiment. Overall, participants preferred a lower risk of ejaculatory dysfunction, lower urgency and duration of urination, lower probability of permanent incontinence, lower frequency of nighttime and daytime urination, and lower probability of needing another surgery. Moreover, a faster onset of overall symptom reduction was preferred. Several patient characteristics especially characteristics related to a patient's sexual life seem to influence patients' preferences. Conclusions: Significant preference heterogeneity could be observed in this study, and subgroup analyses suggest differences in preferences in relation to patients' characteristics. These findings highlight the need for individualized treatment decisions. Physicians should evaluate patients' clinical but also inquire about a patient's personal situation and preferences to select the optimal treatment in collaboration with the individual patient.

Patient preferences for metastatic prostate cancer treatment: a discrete choice experiment

BackgroundTo examine the preference weightings for risk/benefit attributes of therapy in metastatic prostate cancer(mPC) patients, encompassing hormone-sensitive(mHSPC) and castration-resistant(mCRPC) settings. Patients and MethodsA non-interventional cross-sectional survey employing a discrete choice experiment was conducted, recruiting 200 mHSPC and 100 mCRPC patients within 5 years of diagnosis from the urology and oncology specialty clinics between Feb 2023 and Jul 2023. Patients were randomized into 2 blocks of 9 questions, choosing 1 out of 2 medication profiles consisting five attributes, each with 3 levels, determined from a group interview of 5 patients. A mixed logit model estimated attribute-level preference weightings, with tradeoff points calculated. ResultsMedian age was 75(IQR:71-81), 170(56.7%) had no income, 245(81.7%) cared for themselves, mean maximum out-of-pocket treatment cost was US$20,456(SD:43,568), and 160(53.3%) claimed not to consider further treatment when cost exceeding their affordability. Patients favoured self-care ability(4.37,P<.001) and life expectancy extension(2.83,P<.001), disfavoured adverse effects (-6.97,P<.001) and treatment cost(in HK$million or USD$128,205)(-3.14,P<.001). mCPRC patients was more sensitive to treatment cost(-3.61vs-2.97), life expectancy extension(3.47vs2.55) and adverse effects(-7.55vs-6.80) compared to mHSPC patients. Higher financial affordability patients exhibited higher sensitivity to self-care ability(4.89vs4.02) and adverse effects(-7.57vs-6.70). ConclusionThe chance of adverse effects was pivotal in treatment decisions, followed by self-care ability, with cost remaining a major access barrier. Micro AbstractExamining the preference weightings for risk/benefit attributes of therapy in metastatic prostate cancer patients, we recruited 200 hormone-sensitive and 100 castration-resistant patients for a cross-sectional discrete choice experiment survey. A mixed logit model estimated attribute-level preference weightings, calculating tradeoff points. The chance of adverse effects and self-care ability were pivotal in treatment decisions, with cost remaining a major access barrier.

Evaluating the Importance of Return to Sports and Hamstring Strength in a Discrete Choice Experiment for Anterior Cruciate Ligament Injury.

With emerging treatments for anterior cruciate ligament (ACL) injury, analysis of patient preferences is lacking to align clinical care and research with patient priorities. To identify patient priorities for outcomes after surgical intervention if they were to sustain an ACL tear, analyze what outcome measures influenced preferences, and determine whether patient demographics influenced preferences. Cross-sectional study. The authors screened patients aged 18 to 30 years who presented for upper extremity complaints to a single institution in 2023. Patients were excluded for current lower extremity injury or history of a knee injury requiring surgical consultation. The authors designed a discrete choice experiment through literature review of outcome measures for bridge-enhanced ACL restoration (BEAR) and ACL reconstruction (ACLR) with hamstring tendon autograft. Measures included return to sports, risk of arthritis, risk of reinjury, and hamstring strength. Patients chose surgery A (ACLR with hamstring tendon autograft) or surgery B (BEAR) and then rated the importance of each outcome measure on their selection. In total, 100 participants (36 female; mean age, 25.1 ± 4.0 years) completed the discrete choice experiment. Overall, 56.0% participated in sports and 80.0% were employed. Based on surgery choice group, there were no significant differences in sex, age, Marx Activity Scale score, sports participation, or employment status between patients who selected BEAR or ACLR with hamstring tendon autograft (all P > .361). Return to sports and hamstring strength were significant priorities for patients in procedure selection (P ≤ .011). Of the patients who selected ACLR with hamstring tendon autograft, 31.6% would not elect to undergo this procedure. In this discrete choice experiment of adults without prior ACL injury, return to sports and hamstring strength were identified as patient priorities when selecting a procedure for ACL injury. Risk of reinjury, however, was not a significant factor in procedure selection. Importantly, these priorities were maintained regardless of patient characteristics, activity level, or employment status.

Branding locally produced chicken in Ghana: An application of discrete choice experiment

Branding is gradually becoming an essential component of successful agribusinesses and a significant motivation to boost modern agriculture. The study aimed to investigate broiler farmers' choices and preferences for branding locally produced chicken in Ghana. Primary data was collected from 562 broiler producers using a multistage sampling technique. The Discrete Choice Experiment model, which comprises random parameter logit and conditional logit models, was used to analyse farmers' preferences for branding attributes and willingness to brand locally produced chicken. Branding attributes of brand source, production claim, form of branded chicken, percentage of farm use, and price were analysed. Averagely, farmers were willing to pay US$0.59 to brand 1.9 kg of processed chicken. Further, household size, brand source, production claim, form of branded chicken, percentage of farm use, and membership of a farmer-based organisation positively influenced farmers' willingness to brand locally produced chicken. In contrast, price negatively influenced farmers’ preference for branding. Farmers should produce brands with these unique attributes to boost sales, improve income and enhance the competitiveness in the poultry industry.

Ride-Hailing Drivers' Preferences for Fairwork Principles of Satisfactory Working Conditions and Fair Pay-Profit Distribution and Willingness to Form and Join Worker-Platform Co-Operatives in Kenya

Ride-hailing drivers (e-drivers) are among the platform workers who successfully embrace the worker-platform co-operative model's emergence to counter capitalistic ride-hailing platforms and their complex ecosystems, which align with fairwork principles of pay, condition, contracts and (platform) management. This study was conducted to determine the extent of ride-hailing drivers' preferences for satisfactory working conditions, fair pay-profit distribution and willingness to form and join worker-platform co-operatives in Kenya. The study was grounded in the social exchange theory, affective theory of social exchange, and utility theory. The researcher applied critical-realism research philosophy and multimethod research designs of discrete choice experiments and sequential explanatory mixed method research designs. Using the Yamane sampling formula, the study used quantitative data from 497 respondents from sampled 600 of the 20,000 e-drivers in the Nairobi Metropolitan Region. The quantitative data was analysed using multinominal logistic regression. Moreover, the study used qualitative data from 11 participants, which was analysed using thematic analysis. Results indicated that the two fairwork principles were statistically significant to e-drivers’ willingness to form and join worker-platform co-operatives. fair pay-profits distribution (FPD) principle, in particular, was a highly preferred fairwork principle in terms of e-drivers’ willingness to form and join the worker-platform co-operative model (Coeff=1.564, SE = 0.234, Z = 6.67, p&lt; .001), compared to the satisfactory working conditions (SWC) principle (Coeff=0.783, SE = 0.156, Z = 5.012, p&lt; .001). This study brings practical and theoretical contributions to improve the e-drivers’ benefits from the ride-hailing sector. Policymakers, promoters, and platform workers like e-drivers could understand how best to promote worker-platform co-operatives to succeed in the country’s societal context.

Short-term summer trips: Climate hazards & substitution

Climate change and related impacts on tourism and outdoor recreation in Austria are increasingly felt in the number of hot days and variable weather conditions. This paper investigates how these effects likely influence visitor behavior in the future. A survey with an integrated discrete choice experiment was applied combining weather information, travel distances, travel means, attraction type, certification and parking fees (N = 5544). The analysis of the results yielded a four-class model which showed different substitution behaviors during unpleasant weather conditions, making clear that decisions are based on complex trade-offs and lead to significant behavioral changes under climate change conditions. For destination management, these innovative insights into planning behavior and greater understanding of the four segments are crucial for future product development.

On the psychology of environmental preferences: The influence of contextual priming on discrete choice experiments.

This paper addresses an important gap in discrete choice experiments literature regarding the effect of contextual priming on preferences and willingness to pay. Contextual priming arises when the mere context in which a survey takes place-whether interviewees are approached in areas related or unrelated to the target issue under evaluation-can sway stated choices. We found priming to have a significant effect on one of the analyzed attributes associated with managing a natural park. We recommend interviewing participants in locations that are neutral with respect to the attributes under investigation. This procedure would prevent researchers from communicating incorrect recommendations to policymakers, natural resource planners, and managers.

Financial Fraud Detection Study - Based on Logit Model

The problem of financial fraud has always been a key issue of concern for researchers at home and abroad, and financial fraud of listed companies occurs from time to time at home and abroad, which produces a huge loss of interest for investors as well as the downturn and instability of the capital market, for this reason, it is necessary to carry out a study on the detection of financial fraud. This paper analyzes the financial fraud detection of Chinese listed companies by establishing a Logit model, firstly, obtain the financial statement sample data of Chinese listed companies from CSMAR, and divide the sample into training set and test set with the ratio of 9:1 to preprocess the sample data and fill in the missing values; secondly, this paper selects the financial statement data, and based on the previous research, selects the characteristics that are related to the risk of financial fraud and constitute the risk of financial fraud. high features, and constitute the feature indicators for financial fraud detection; again, since detecting financial fraud is a binary classification problem, the sample is divided into fraudulent companies and normal companies, so this paper studies the financial fraud problem through the discrete choice model in the econometric model, constructs a Logit model, conducts a goodness-of-fit test on the sample data of CSMAR, and estimates the parameters using the method of maximum likelihood estimation ; finally, the test set data is used to test the model's ability to predict financial fraud.

What do urban consumers want? Findings from a discrete choice experiment on the preference for locally produced staple food in Central Africa: Evidence from the Democratic Republic of Congo (DRC)

ABSTRACT A discrete choice experiment in Kinshasa (DRC) investigated urban consumers' preferences between imports and local options for five staple foods – cassava, rice, maize, sugar and cooking oil – under a random utility model. We also examined how distance, packaging and price influenced consumer choice. To assess whether preferences could be manipulated, we introduced two treatment groups – local, import – and a control group. We did not find support for a preference for imports. Instead, there is a statistically significant preference for local products, with the exception of sugar. Respondents are willing to pay 28% more for local food, a premium quantified at 1540 CF (.93 USD) per kg for maize and 1091CF (.66 USD) per litre for oil. Packaging is an attribute of influence as the willingness to pay (WTP) in full remains positive when products interact with packaging and with price. There is demand for local products for which consumers are willing to pay a premium. Yet, DRC imports 1.5 billion dollars of food yearly with only 10% of its arable land exploited. The increased urban consumption of imports does not signify a bias against local products, but rather points to structural issues undermining local supply. DRC needs to develop local value chains linking rural farmers to urban markets through the transformation of local foods to meet urban needs and to convert the WTP into a producer surplus benefiting rural livelihoods.

Identification of Average Marginal Effects in Fixed Effects Dynamic Discrete Choice Models

Abstract In nonlinear panel data models, fixed-effects methods are often criticized because they cannot identify average marginal effects (AMEs) in short panels. In contrast with that criticism, we prove the point identification of different AMEs, including causal effects of changes in the lagged dependent variable or the last choice's duration, in a panel dynamic logit model for T as small as three. Our proofs are constructive and provide simple closed-form expressions for the AMEs in terms of probabilities of choice histories. We illustrate our results using Monte Carlo experiments and with an empirical application of a dynamic model of consumer brand choice.

The effect of hedonic and eudaimonic happiness in driving altruistic food choices

AbstractThis study investigates whether individual happiness affects prosocial behavior in food choices. We considered two distinct dimensions of happiness: hedonic and eudaimonic. The hedonic component is focused on pleasure, joy, and immediate gratification, while the eudaimonic aspect is related to a sense of purpose in life, personal growth, and the fulfillment of individual aspirations. We conducted a discrete choice experiment to assess if happy people are more prone to altruistic choices when buying food. The results indicate that individual happiness exerts distinct effects according to its two dimensions, eudaimonia and hedonism. We found that happiness influences the demand for ethical foods, whereas it exerts a detrimental effect on preferences for food with environmental labels.

Preferences for pre-exposure prophylaxis delivery among HIV-negative pregnant and breastfeeding women in Zambia: evidence from a discrete choice experiment.

Pregnant and breastfeeding women at substantial risk for HIV infection in sub-Saharan Africa can benefit from biomedical interventions such as pre-exposure prophylaxis (PrEP). We estimated the benefit that pregnant and breastfeeding women may derive from PrEP service delivery in order to guide PrEP roll-out in the target population in Zambia. Between September and December 2021, we conducted a discrete choice experiment (DCE) among a convenient sample of 389 pregnant and breastfeeding women not living with HIV in Lusaka, Zambia. Women aged 18 years or older, with a documented negative HIV result in their antenatal card responded to a structured questionnaire containing 12 choice sets on service delivery attributes of PrEP: waiting time at the facility, travel time to the facility dispensing PrEP, location for PrEP pick-up, health care provider attitude and PrEP supply at each refill. Mixed logit regression analysis was used to determine the participant's willingness to trade off one attribute of PrEP for the other at a 5% significance level. Willingness to wait (WTW) was used to determine the relative utility derived from each attribute against waiting time. Waiting time at the facility, travel time to the facility, health care provider attitude and amount of PrEP supply at each refill were important attributes of PrEP service delivery (all p < 0.01). Participants preferred less waiting time at the facility (β = -0.27, p < 0.01). Women demonstrated a strong preference for a 3-months' supply of PrEP (β = 1.69, p < 0.01). They were willing to wait for 5 h at the facility, walk for more than an hour to a facility dispensing PrEP, encounter a health care provider with a negative attitude in order to receive PrEP enough for 3 months. Patient-centered approaches can help to inform the design and implementation of PrEP services among pregnant and breastfeeding women. In this study, we found that a reduction in clinic visits-including through multi-month dispensing of PrEP-could improve uptake of services in antenatal and postnatal settings.

What matters most to healthy older adults in treatment decision making: a discrete choice experiment

Abstract Introduction Shifting to a patient centered approach is crucial for a sustainable healthcare system. Understanding individuals’ priorities is essential for personalized care, especially in critical illness. Treatment decisions are often aimed at disease-specific outcomes such as life extension or survival, while patient-specific outcomes like maintaining independence may be equally vital. How healthy older adults prioritize treatment outcomes in case of a critical illness is currently unknown. Enhanced insight into their priorities can refine healthcare policy, for more personalized care. This study investigated outcomes (attributes) prioritized in hypothetical decision-making by healthy adults over 50 yr. Methods We conducted a Discrete Choice Experiment with individuals aged ≥50, comparing six pairs of hypothetical treatments with five attributes: life expectancy, independence, pain, memory complaints and societal costs. Attribute utility was analyzed using a conditional logit model, and latent class analyses were employed to explore preferences in groups. Results In 333 participants (mean age 70 +/- 7.7) all attributes emerged as impactful with independence being strongest (p &amp;lt; 0.05). Increased life expectancy had positive utility, but only for a two-year increase. Negative utility was found for all other attributes except mild pain and memory complaints. Latent class analyses identified two groups (22.4% and 77.6%). Group one valued life expectancy more (p .019 vs .940), whereas the second group valued independence (p .058 vs.&amp;lt;.001 and societal costs (p.053 vs. &amp;lt;.001) more. Conclusions In a hypothetical case of life-threatening disease, for people aged ≥ 50 life expectancy was not the sole relevant outcome for treatment decisions; pain, independence and societal costs are important and should be discussed in clinical decision making or healthcare policy. Key messages • Older adults find patient-specific outcomes relevant for decision making. • Societal costs are found relevant for decision making for treatment by older adults.

Preferences for genetic interventions for SCA and Huntington’s disease: results of a discrete choice experiment among patients

BackgroundAlthough genetic interventions are on the horizon for some polyglutamine expansion diseases, such as subtypes of spinocerebellar ataxia (SCA) and Huntington’s disease (HD), the patients’ preferences regarding these new therapies are unclear. This study aims to get insight into what extent different characteristics of genetic interventions affect the preferences of patients with SCA and HD with regard to these interventions.MethodsManifest and premanifest patients with SCA or HD were recruited online by platforms of patient associations. The respondents conducted a questionnaire that included a discrete choice experiment (DCE). The experimental design included 24 choice sets, but these were divided into three blocks of eight to reduce the number of tasks per respondent. Each choice set included two alternative treatments and consisted of four attributes (mode and frequency of administration, chance of a beneficial effect, risks, and follow-up), each with three or four different levels. The forced choice-elicitation format was used. Data were analyzed by using a multinominal logistic regression model.ResultsResponses of 216 participants were collected. The mode and frequency of administration of a genetic intervention, as well as the chance of a beneficial effect both influence the choice for a genetic intervention. Respondents less prefer repeated lumbar punctures compared to a single operation. As expected, a higher beneficial effect of treatment was preferred. Risks and follow-up did not influence the choice for a genetic intervention.ConclusionsThe results can be used for the design and implementation of future genetic interventional trials as well as of patient-centered care pathways for rare movement disorders such as SCA and HD.

Job preferences of master public health candidates in Northeast China based on discrete choice experiments

BackgroundThe shortage of health workers in rural and remote areas is a key issue for global health systems, including China. Public health undertakings in Northeast China face the risk of a talent gap. In September 2023, the National Development and Reform Commission (NDRC) held a symposium on promoting the comprehensive revitalization of Northeast China in the New Era, proposing to support the comprehensive revitalization of Northeast China with high-quality population development, strengthen the development and utilization of human resources, and increase policy support for the revitalization of talent.MethodsThe questionnaire was designed by discrete choice experiments, and 1208 Public Health Master’s candidates from six universities in Northeast China were investigated online via the Powercx system network survey platform in April 2024. The mixed logit model was used to analyze the job preferences of Master Public Health candidates.ResultsAll 7 attributes included in the study had statistically significant effects on the job preferences of public health master’s degree candidates (P < 0.05). They tended to choose jobs with higher monthly income (12,000 CNY/month), located in cities with good working environments and with Bianzhi when seeking jobs. There is heterogeneity in job preference, and different preference characteristics are displayed in different subgroups.ConclusionThis study revealed that public health master’s degree candidates in Northeast China were more willing to choose jobs with higher monthly incomes, working places in cities and better working environments. The way to formulate a combination of policy packages is more attractive than improving a single aspect alone. Since the preferences of each subgroup are different, the preference characteristics of the target population should also be considered when formulating the policy package to meet the challenges of talent attraction and retention.

Economic assessment of ecosystem services with a novel concept of elevation: An application of the discrete choice experiment method

AbstractThis research was conducted in the Hei River Basin of China to understand respondents' willingness to pay (WTP) for ecological services towards sustainable river system management. A discrete choice experiment is used to gauge respondents' preferences. In addition, elevation was introduced as a novel spatial attribute to account for heterogeneity. Primary data from 1680 respondents were collected across the Hei River Basin. The elevation of the river was categorized into five ad hoc elevation ranges to analyze the potential effects of elevation on environmental attributes. These samples were stratified as 1000–1600 m, 1601–2200 m, 2201–2800 m, 2801–3400 m, and 3401–4000 m. Pooled data results showed that the maximum WTP was for water quality, that is, 142.05 RMB, without considering the effect of elevation. However, when the interaction with elevation was included, the amount decreased to 133.52 RMB. Likewise, elevation‐based group estimates showed a varied pattern of spatial preference, with different preferences for each distinguishing attribute. Group A prioritized water quality (92.81 RMB) and the East Juyan area (4.12 RMB). In contrast, Group B preferred the guaranteed rate of irrigation of farmland (3.50 RMB) and reduced sandstorm frequency (17.90 RMB). Leisure and entertainment conditions had the lowest WTP across all groups (0.09–0.50 RMB). These findings highlight the importance of incorporating respondents' preferences in restoring and maintaining river systems. Additionally, it emphasized the need to consider respondents' socioeconomic characteristics when developing sustainable management policies.

Decision-analytic modelling of costs &amp; benefits of adding sigmoidoscopy to CRC screening in Germany

Abstract Background In Germany, a colorectal cancer (CRC) screening programme is in place that entitles individuals to a stool test or colonoscopy. However, less than half of those eligible participate. The inclusion of an additional screening option, such as the evidence-based sigmoidoscopy, could lead to a higher overall participation rate, but also to individuals preferring the additional option to the more effective colonoscopy. The objective of this modelling study is to estimate the impact of offering sigmoidoscopy as an additional option for CRC screening in Germany. Methods A life-time mathematical model (Markov model) is developed to analyse the long-term effects of the additional offer of sigmoidoscopy on benefits (prevalence, mortality, health-related quality of life (HRQoL)), costs, and cost-effectiveness. The model is based on systematic literature reviews and real-world healthcare data. It incorporates disease development, sensitivity and specificity of the options, compliance rates, survival probabilities and background mortality. A discrete choice experiment (DCE) was conducted to estimate the future uptake of the options (stool test, colonoscopy, sigmoidoscopy, no screening) based on stated preferences of n = 666 individuals. Results Adding sigmoidoscopy leads to greater effectiveness of the CRC screening programme in terms of increased screening participation, increased adenoma detection, decreased disease-specific mortality, and improved discounted HRQoL. However, it also incurs higher costs. The incremental cost-effectiveness ratios (ICER) for men and women are €507 per quality-adjusted life year gained (QALYg) and €74 per QALYg, respectively. Conclusions The results indicate that the inclusion of sigmoidoscopy in the German CRC screening programme would be cost-effective and that sigmoidoscopy should be piloted in practice. The expanded programme has the potential to enhance the program’s effectiveness, improve health outcomes, and reduce the burden of CRC. Key messages • Expanding the CRC screening programme may increase overall participation, resulting in higher costs, but also greater effectiveness in detecting more adenomas, reducing mortality, improving HRQoL. • Introducing sigmoidoscopy in Germany appears cost-effective and justifies practical piloting to enhance CRC screening efficacy and health outcomes.

Discrete Choice Experiment on Financial Incentives for Engaging Young Adults in Vaping Cessation Programs

Introduction Contingency management involves rewarding individuals based on objective evidence of behavioral changes. This study explores preferences for financial incentives in vaping cessation programs. Methods A discrete choice experiment (DCE) was conducted among young adult current e-cigarette users aged 19-29. DCE attributes (and levels) included reward amount ($100, $300), reward schedule (consistent value, escalating value), reward procedure (gain-framed, loss-framed), vaping education modules (yes, no), text messaging support (yes, no), and cost ($30, $100). Participants were randomized into one of the four blocks, each containing four choice sets. Each choice set presented two hypothetical vaping cessation programs. Choice data (n × choice sets × alternative programs = 154 × 4 × 2 = 1,232 observations) were analyzed using generalized estimation equation models. Results Participants showed a preference for vaping cessation programs offering a higher reward amount (odds ratio [OR] = 11.5; 95% CI,7.0-19.2), gain-framed rewards for sustained abstinence (OR = 1.4; 95% CI,1.0-1.8), text messaging support (OR = 1.9; 95% CI,1.4-2.5), and a lower program cost (OR = 2.6; 95% CI,1.8-3.8). Interaction tests showed significant effects of the rewards procedure among daily e-cigarette users (adjusted OR [AOR] = 2.1; 95% CI,1.3-3.5), but not some-day users; and among those with no quit attempts in the past six months (AOR = 2.7; 95% CI,1.5-4.7), but not those with previous quit attempts. Female participants preferred text messaging support (AOR = 3.6; 95% CI,2.3-5.4), whereas male participants did not show this preference. Conclusion A multifaceted vaping cessation intervention augmented with financial incentives might improve participation and engagement among young adults. Future studies should investigate how these attributes can enhance program reach and vaping abstinence outcomes in real-world settings.

Animal Welfare or Own Welfare: What Motivates Consumers’ Choice of Cage‐Free Products?

ABSTRACTThis study addresses the puzzle of animal welfare regulations consistently passing by majority votes, despite potential welfare losses evident in market data. To understand this phenomenon, we propose a conceptual framework that considers two possibilities: first, animal welfare might not be valued in the market, as suggested by classical externality analysis, and second, it could be valued due to altruistic motivations. To illustrate the framework, we uncover the motives driving consumers’ demand for animal welfare products jointly utilizing the results of a discrete choice experiment and respondents’ perception data obtained in China. Our findings align with the predictions made by classical externality analysis, indicating that the public good aspect of animal welfare is not valued in this market and thereby challenging the existence of altruistic behavior. Moreover, our analysis of consumer heterogeneity reveals that as consumers’ knowledge increases, they exhibit a decreased inclination to prioritize the animal welfare attribute for fulfilling their private needs, and may raise concerns about the safety of animal welfare‐friendly products.
