Abstract Objective To promote public health and resume university activities, COVID-19 vaccination has been mandated from an increasing number of universities worldwide. The objective of the study is to understand the factors that impact preference and willingness to take the vaccine among university students in Hong Kong universities utilizing an online questionnaire. The findings will be imperative for health education and the success of the vaccination program. Results We conducted a discrete choice experiment survey among university students in Hong Kong and applied conditional logit regression to estimate their vaccine preference and the weight of each attribute. Regression results showed adverse reactions, efficacy, origin of the vaccine, required number of doses and out-of-pocket price are significant determinants for the choice of vaccine, ranked from the most to least important. Similar preference weighting results were observed after adjusting age, sex, monthly household income, studying medical-related subjects and recent influenza vaccination. Safety, efficacy and origin of the vaccine are key drivers for vaccination decisions among young adults in Hong Kong. Health education and communication focused on these factors are urgently needed to overcome vaccine hesitancy and improve the vaccine uptake.

Background: Along with individual-level factors, vaccination-related characteristics are important in understanding COVID-19 vaccine hesitancy. This study aimed to determine the influence of these characteristics on vaccine acceptance to formulate promotion strategies after considering differences among respondents with different characteristics.Methods: An online discrete choice experiment was conducted among people aged 18–64 years in Hong Kong, China, from 26 to 28 February 2021. Respondents were asked to make choices regarding hypothetical vaccination programmes described by vaccination-related characteristics—the attributes derived from a prior individual interview. Subgroup analysis was performed to identify the differences in vaccination-related characteristics among respondents with different personal characteristics.Results: A total of 1,773 respondents provided valid responses. The vaccine efficacy and brand were the most important factors affecting acceptance, followed by the exemption of quarantine for vaccinated travelers, safety, venue for vaccination, vaccine uptake of people in their lives, and recommendations by general physicians or government. Frequent exposure to vaccination information on social media has been associated with increasing vaccine refusal. Substantial preference heterogeneity for the attributes was found among people of different ages, incomes, chronic conditions, and previous acceptance of influenza vaccines.Conclusion: The findings provided evidence to formulate interventions to promote vaccine uptake, including the provision of vaccination at housing estate or workplaces, involvement of general physicians and interpersonal communication in vaccine promotion and information dissemination, and exemption of quarantine for vaccinated people. Moreover, social media is a significant information channel that cannot be neglected in the dissemination of official information.

BACKGROUND Virtual reality (VR) can be used to build many different scenes aimed at reducing study-related stress. However, few academic experiments about university students for preference testing have been done. Our study aimed to assess the preference of VR games for stress and depression prevention by using a discrete choice experiment (DCE). OBJECTIVE The candidate could wear the headset and alleviate the stress and depression in the game. The purpose of this experiment was to investigate the preference of VR technology in college students’ psychological pressure relief and depression prevention. METHODS Five different attributes were selected based on the depression therapy parameter and attributes about VR: (1) treatment modality, (2) therapy duration, (3) perceived remission rate, (4) probability of adverse events, and the (5) monthly cost of adding treatment to a discrete choice experiment. By comparing different attributes and levels, we could draw some conclusions about the depression therapy testing preference for university students. One university student was responsible for VR scene development and one for candidate recruitment. RESULTS The utility report of different attributes for “zero” probability of adverse events was higher than others (99.22), and the VR treatment as the most popular treatment method when compared with counseling and medicine treatment was 80.95. Three parameter aspects (different treatments for depression) were statistically significant (P＜0.001), including “0%” and “50%” of “Probability of adverse events” and “RMB$500” of “The monthly cost of treatment”. Most individuals preferred 12 months as the therapy duration, and the odds ratio of “12 months” was 1.095 (95% confidence interval [CI] 0.945–1.270) when compared with the reference of level of “6 months”. Meanwhile, the cheapest price (RMB $500) of depression therapy was the optimum choice for most students. CONCLUSIONS People placed great preference on VR technology psychological intervention methods, which indicates that VR may have a potential market in prevention and treatment of psychological problems. However, adverse events and treatment costs need to be considered. This study can be used to guide policies that are relevant to the development of application of VR technology in the field of psychological pressure and depression prevention.

ObjectiveTo inform the development of a patient-reported outcome measure, the aim of this study was to identify which symptoms and feelings following percutaneous coronary intervention (PCI) are most important to patients.DesignDiscrete-choice experiment consisting of two hypothetical scenarios of 10 symptoms and feelings (pain or discomfort; shortness of breath; concern/worry about heart problems; tiredness; confidence to do usual activities; ability to do usual activities; happiness; sleep disturbance; dizziness or light-headedness and bruising) experienced after PCI, described by three levels (never, some of the time, most of the time). Preference weights were estimated using a conditional logit model.SettingFour Australian public hospitals that contribute to the Victorian Cardiac Outcomes Registry (VCOR) and a private insurer’s claim database.Participants138 people aged >18 years who had undergone a PCI in the previous 6 months.Main outcome measuresPatient preferences via trade-offs between 10 feelings and symptoms.ResultsOf the 138 individuals recruited, 129 (93%) completed all 16 choice sets. Conditional logit parameter estimates were mostly monotonic (eg, moving to worse levels for each individual symptom and feeling made the option less attractive). When comparing the magnitude of the coefficients (based on the coefficient of the worst level relative to best level in each item), feeling unhappy was the symptom or feeling that most influenced perception of a least-preferred PCI outcome (OR 0.42, 95% CI 0.34 to 0.51, p<0.0001) and the least influential was bruising (OR 0.81, 95% CI 0.67 to 0.99, p=0.04).ConclusionThis study provides new insights into how patients value symptoms and feelings they experience following a PCI.

Increased vaccine hesitancy and refusal negatively affects vaccine uptake, leading to the reemergence of vaccine preventable diseases. We aim to quantify the relative importance of factors people consider when making vaccine decisions for themselves, or for their child, with specific attention for underlying motives arising from context, such as required effort (accessibility) and opportunism (free riding on herd immunity). We documented attitudes towards vaccination and performed a discrete choice experiment in 4802 respondents in The United Kingdom, France and Belgium, eliciting preferences for six attributes: (1) vaccine effectiveness, (2) vaccine preventable disease burden, (3) vaccine accessibility in terms of copayment, vaccinator and administrative requirements, (4) frequency of mild vaccine-related side-effects, (5) vaccination coverage in the country’s population and (6) local vaccination coverage in personal networks. We distinguished adults deciding on vaccination for themselves from parents deciding for their youngest child. While all attributes were found to be significant, vaccine effectiveness and accessibility stood out in all (sub)samples, followed by vaccine preventable disease burden. We confirmed that people attach more value to severity of disease compared to its frequency, and discovered that peer influence dominates free-rider motives, especially for the vaccination of children. These behavioral data are insightful for policy and are essential to parameterize dynamic vaccination behavior in simulation models. In contrast to what most game theoretical models assume, social norms dominate free-rider incentives. Policy-makers and healthcare workers should actively communicate on high vaccination coverage, and draw attention to the effectiveness of vaccines while optimizing their practical accessibility.

As consumption behavior is one of the key human activities destabilizing the Earth system, green consumption is expected to increase. However, although consumers often show interest in green consumption, they tend to choose non-green alternatives. Presuming that one of the reasons for their inconsistency lies in the trade-offs between green attributes and other attributes (e.g., brand, performance, and price), this study adopted a discrete choice experiment to understand how green attributes play a role in consumers’ purchase decisions. To obtain a deeper understanding, the study conducted a cross-country (young Japanese [n = 370] and Vietnamese [n = 403] consumers) and product (water bottles and T-shirts) comparative analysis. The findings showed that for both products, Japanese respondents were less appreciative of green attributes in both relative and absolute terms than Vietnamese respondents. Furthermore, the marginal willingness to pay (MWTP) for a low environmental impact was the highest among the other attributes in both products for Vietnamese respondents, while this was not the case for Japanese respondents. Utilizing the findings obtained from the conditional logit models and MWTP, this study proposes several policy implications for the promotion of green purchases suitable for each country’s unique situation.

Background: Mandatory vaccination has been mooted to combat falling childhood vaccine uptake rates in England. This study investigated parental preferences for a mandatory vaccination scheme. Methods: Discrete choice experiment. Six attributes were investigated: vaccine (MMR, 6-in-1), child age group (2 years and older, 5 years and older), incentive (130 GBP cash incentive for parent, 130 GBP voucher incentive for child, no incentive), penalty (450 GBP fine, parent not able to claim Child Benefits for an unvaccinated child, unvaccinated child not able to attend school or day care), ability to opt out (medical exemption only, medical and religious belief exemption), and compensation scheme (not offered, offered). Mixed effects conditional logit regression models were used to investigate parental preferences and relative importance of attributes. Findings: Participants were 1,001 parents of children aged 5 years and under (53% female, mean age=33.6 years, SD=7.1, 84% white British). Parental preferences were mostly based on incentives (slight preference for cash pay-out for the parent versus a voucher for the child) and penalties (preference for schemes that did not allow unvaccinated children to attend school or day care and those that withheld financial benefits for parents of unvaccinated children). Parents also preferred schemes that: offered a compensation scheme, mandated the 6-in-1 vaccine, mandated vaccination in children aged 2 years and older, and that offered only medical exemptions. Interpretation: Results can inform policymakers' decisions about how best to implement a mandatory childhood vaccination scheme in England. Funding: Data collection was funded by a British Academy/Leverhulme Small Research Grants (SRG1920\101118).
