Consumers’ Preference and Future Consideration Toward Organic Instant Noodles: Evidence from Indonesia

The consumption of instant noodles in Indonesia is the second highest globally. However, people are now more aware of sustainable lifestyles and the health risks of consuming food additives, so some opt for more organic choices, including instant noodles. Research on customers’ preferences in this area remains lacking, so the current study aims to fill the gap. This study also analyses the relationship between the choices and consumers’ future considerations. Discrete Choice Experiment (DCE) method was used to reveal the perception of sustainable attributes in organic instant noodles. The future considerations were measured using the Future Consequences Consideration (FCC) scale. As many as 592 respondents participated in the study, selected using the convenience sampling method. Data were analyzed using conditional logit via package support.CEs on R software. The findings show that Indonesian consumers’ preferences are primarily based on the extrinsic attributes: organic labels and packaging materials, but they also consider the health claims. They will likely prefer instant noodles with organic characteristics for future considerations. The results of this study have implications for instant noodle product development. Young consumers take up a large portion of the market, and they are now more aware of sustainability and health. The current study can inform the product development and the approach to the targeted market. To the best of the authors’ knowledge, this is the first study on consumer perception on sustainability attributes in organic instant noodles.

A national survey of Iranian general population to estimate a value set for the EQ-5D-5L.

The main aim of this study is to estimate a national value set of the EQ-5D-5L questionnaire for Iran. The composite time trade-off (cTTO) and discrete choice experiment (DCE) methods; and the protocol for EuroQol Portable Valuation Technology (EQ-PVT) were used to estimate the Iran national value set. 1179 face-to-face computer-assisted interviews were conducted with adults that were recruited from five Iran major cities in 2021. Generalized least squares, Tobit, heteroskedastic, logit, and hybrid models were used to analyze the data and to identify the best fitting model. According to the logical consistency of the parameters, significance levels and prediction accuracy indices of the MAE; a heteroscedastic censored Tobit hybrid model combining cTTO and DCE responses was considered as the best fitting model to estimate the final value set. The predicted values ranged from -1.19 for the worst health state (55555) to 1 for full health (11111), with 53.6% of the predicted values being negative. Mobility was the most influential dimension on health state preference values. The present study estimated a national EQ-5D-5L value set for Iranian policy makers and researchers. The value set enables the EQ-5D-5L questionnaire to use to calculate QALYs to assist the priority setting and efficient allocation of limited healthcare resources.

Patient preferences for pilonidal sinus treatments: a discrete choice experiment survey.

A range of treatments are available for pilonidal sinus disease (PSD), each of which has a different risk/benefit profile. The aim of this study was to collect patient views on which interventions they would rather avoid and which outcomes they most value for PSD. We conducted an online survey using the discrete choice experiment (DCE) method. DCE task involved participants choosing the best treatment option when presented with a set of competing hypothetical treatment profiles. Participants with symptomatic PSD, referred for elective surgery were recruited from 33 NHS trusts between 2020 and 2022. Collected DCE data were analysed using regression analyses. One hundred and eleven participants completed the survey. In the overall group, low risk of infection/persistence was the most important characteristic when making a treatment decision (attribute importance score of 70%), followed by treatments with shorter recovery time with an attribute importance score of 30%. The results demonstrated that patients are willing to accept trade-offs between treatment recovery time and risk of infection/persistence. Patients above 30 years old are willing to accept a higher chance of treatment failure in exchange for rapid treatment recovery (risk tolerance between 22.35 - 34.67 percentage points). Conversely, patients in the younger age groups, were risk averse, and were only willing to accept a small risk 1.51-2.15 in exchange for a treatment with faster recovery time. All patient groups appear to the reject the excision and leave open technique due to the need for protracted nursing care. This study highlights the need for shared decision making when it comes to surgery for PSD.

The landscape impact of agricultural sheds in rural UNESCO site: Public preferences and mitigation solutions

The mitigation process of agricultural sheds into the landscape is crucial for aesthetic quality of its landscape and architectural integrity. The evaluation of how residents perceive these elements and identifying preferred solutions is crucial for landscape planning. For identifying sets of preferred mitigation solutions and defining shared criteria for landscape planning a representative sample of the population was investigated. We have estimated the willingness to pay for integrating contemporary agricultural sheds in a UNESCO landscape. Data were collected in six Core Zones of “Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato” (North-West Italy). Preferences toward different mitigation measures of the agricultural sheds were investigated using a Discrete Choice Experiment (DCE) method. The DCE survey was carried out through face-to-face interviews involving 400 residents. The set of mitigation attributes (colour of the walls, colour of the roof, green barriers and plant green walls) was selected by means of a landscape analysis and presented to respondents using a set of images (close and distant views). Our study shows that the presence of green barriers (formal hedge and tree line) and the colour of the wall (green) are considered positive mitigation solutions. These attributes have a positive effect both in the close and the distant view. Our results confirmed that the distance may affect the visual impact of these buildings. Most of the respondents agree with the need to implement mitigation solutions for agricultural sheds, guaranteeing a better aesthetic enjoyment.

Patient Preferences for Pharmaceutical and Device-Based Treatments for Uncontrolled Hypertension: Discrete Choice Experiment.

Discrete choice experiment is a survey method used to understand how individuals make decisions and to quantify the relative importance of features. Using discrete choice experiment methods, we quantified patient benefit-risk preferences for hypertension treatments, including pharmaceutical and interventional treatments, like renal denervation. Respondents from the United States with physician-confirmed uncontrolled hypertension selected between treatments involving a procedure or pills, using a structured survey. Treatment features included interventional, noninterventional, or no hypertension treatment; number of daily blood pressure (BP) pills; expected reduction in office systolic BP; duration of effect; and risks of drug side effects, access site pain, or vascular injury. The results of a random-parameters logit model were used to estimate the importance of each treatment attribute. Among 400 patients completing the survey between 2020 and 2021, demographics included: 52% women, mean age 59.2±13.0 years, systolic BP 155.1±12.3 mm Hg, and 1.8±0.9 prescribed antihypertensive medications. Reduction in office systolic BP was the most important treatment attribute. The remaining attributes, in decreasing order, were duration of effect, whether treatment was interventional, number of daily pills, risk of vascular injury, and risk of drug side effects. Risk of access site pain did not influence choice. In general, respondents preferred noninterventional over interventional treatments, yet only a 2.3 mm Hg reduction in office systolic BP was required to offset this preference. Small reductions in office systolic BP would offset risks of vascular injury or drug side effects. At least a 20% risk of vascular injury or drug side effects would be tolerated in exchange for improved BP. Reduction in systolic BP was identified as the most important driver of patient treatment preference, while treatment-related risks had less influence. The results indicate that respondents would accept interventional treatments in exchange for modest reductions in systolic BP compared with those observed in renal denervation trials.

Understanding what matters to metastatic castration-resistant prostate cancer (mCRPC) patients when considering treatment options: A US patient preference survey.

Understanding how patients perceive the efficacy, safety, and administrative burden of treatments for metastatic castration-resistant prostate cancer (mCRPC) can facilitate shared-decision making for optimal management. This study sought to elicit patient preferences for mCRPC treatments in the US. We conducted a cross-sectional survey using the discrete-choice experiment method. Participants were asked to state their choices over successive sets of treatment alternatives, defined by varying levels of treatment attributes: overall survival (OS), months until patients develop a fracture or bone metastasis, likelihood of requiring radiation to control bone pain, fatigue, nausea, and administration (i.e., oral/IV injection/IV infusion). Using mixed logit models, we determined the value (i.e., preference weights) that respondents placed on each attribute. Relative attribute importance (RAI) and marginal rates of substitution (MRS) were calculated to understand patients' willingness to make tradeoffs among different attributes. The final data set numbered 160 participants, with a mean age of 71.6 years old and a mean of 8.96 years since prostate cancer diagnosis. Participants' treatment preferences were as follows: OS (RAI: 31%), bone pain control (23%), nausea (16%), delaying fracture or bone metastasis (15%), fatigue (11%), and administration (3%). The MRS demonstrated that respondents were willing to trade 1.9months of OS to eliminate moderate nausea and 3.3months of OS for a reduction in fatigue from severe to mild. Improving OS is the highest priority for patients with mCRPC, but they are willing to trade some survival to reduce the risk of requiring radiation to control bone pain, delay a fracture or bone metastasis, and experience less severe nausea and fatigue.

Drivers of Small-Scale Fishers’ Willingness to Adopt Property Rights Co-Management in the Lake Nokoué and Porto-Novo Lagoon Complex in Southeast Benin

The estuarian and lagoon areas of southeast Benin are atypical lake territories where private property rights are hereditary from endogenous legal tradition. People live in stilt dwellings and are exclusively dedicated to free-to-access fishing. Consequently, an increasing number of fishers with low respect for the State’s general rules for sustainable fishing contribute to legal pluralism and the tragedy of the commons. Co-management of small-scale fisheries has been advocated to offer various benefits, including improved socio-ecological integration, shared sustainable livelihoods, and adherence to biodiversity objectives. This study aims to assess the factors that influence the willingness of small-scale fishers to adopt property rights co-management options in southeast Benin. The data were collected using the discrete choice experiment method. The results show that 44% of fishers are willing to adopt property rights co-management options. This willingness is determined by their involvement in the co-management committee, access to a subsidy and livelihood diversification options. These fishers are the oldest in the sample and primarily owners of Acadja, a traditional fishing tool made of bush and tree branches planted in the lake. Institutional agreements for co-management establishment, such as subsidies to support small-scale fishers’ livelihood diversification and capacity-building, must be set up to achieve co-management goals.

What drives the acceptability of restrictive health policies: An experimental assessment of individual preferences for anti-COVID 19 strategies.

The public acceptability of a policy is an important issue in democracies, in particular for anti-COVID-19 policies, which require the adherence of the population to be applicable and efficient. Discrete choice experiment (DCE) can help elicit preference ranking among various policies for the whole population and subgroups. Using a representative sample of the French population, we apply DCE methods to assess the acceptability of various anti-COVID-19 measures, separately and as a package. Owing to the methods, we determine the extent to which acceptability depends on personal characteristics: political orientation, health vulnerability, or age. The young population differs in terms of policy preferences and their claim for monetary compensation, suggesting a tailored policy for them. The paper provides key methodological tools based on microeconomic evaluation of individuals’ preferences for improving the design of public health policies.

An Investigation of Job Attribute Preferences of Disadvantaged Beneficiaries of Hybrid Organizations

While scholarship in hybrid organizing of social enterprises has gained maturity in recent years, most existing studies have examined hybrid organizing at the internal and organizational level, and lesser is known about the tensions, balance and trade-offs within individual beneficiaries that served by social enterprises. Given the centrality of the employment of marginalized individuals served in the value creation of social enterprises, it is necessary to deepen our theoretical understanding of whether, how, and to what extent disadvantaged beneficiaries of social enterprises make employment decisions. Adopting an individual-level perspective, this study embarked on a quantitative exploration by testing how disadvantaged employees of social enterprises evaluate different job attributes and their attribute levels using the discrete choice experiment method. We found that opportunities to build social relations, employee recognition, potential earnings, career advancement opportunities, and workplace support had positive and significant influences on disabled individuals’ job preference decisions. Among all, the economic dimension had the greatest importance. This paper contributes to social entrepreneurship research by examining job attribute preferences of disadvantaged employees within the theoretical logic of hybridity as it is nested within individuals. We also stimulate a new conversation on an understudied domain of “individual preferences” within the discourse on social entrepreneurship.

PATIENT PREFERENCES FOR PHARMACEUTICAL AND INTERVENTIONAL HYPERTENSION TREATMENTS: RESULTS FROM A DISCRETE CHOICE EXPERIMENT

Objective: To quantify patient benefit-risk preferences for interventional and pharmaceutical treatments for hypertension (HTN) using discrete choice experiment (DCE) methods. Design and method: A DCE is an established survey method commonly used to quantify preference for selected treatment attributes in hypothetical profiles, allowing estimation of tradeoffs that are acceptable when evaluating several attributes together. Respondents with physician confirmed uncontrolled HTN were presented with a series of questions with hypothetical HTN treatments with differing levels of treatment risk and benefit. Respondents could also choose no HTN treatment. A random parameters logit analysis of the survey treatment choices was used to estimate the relative preferences and importance for each attribute. Results: 400 patients completed the survey, with 52% female, mean age 59 ± 13 years, systolic blood pressure (BP) 155 ± 12 mmHg and 1.8 ± 0.9 average prescribed antihypertensive medications. Reduction in office systolic blood pressure (BP) was the most influential treatment attribute. The remaining attributes were less impactful on respondents’ treatment choice (i.e., duration of effect, whether treatment was interventional, number of daily pills, risk of vascular injury, risk of medication side effects, and risk of temporary pain and bruising). When given a choice between no HTN treatment and an interventional treatment with a 20% risk of procedure side effects, the likelihood of selecting the interventional treatment increased with the magnitude of blood pressure reduction. No more than a 2.5 mmHg reduction in office systolic BP was sufficient to offset treatment risks associated with an interventional procedure like RDN. Conclusions: Among U.S. patients with HTN, a DCE study demonstrated that BP reduction was the most important driver of choice, risks were less important, and a minimal BP reduction was sufficient to offset treatment risks associated with an interventional procedure like RDN.

The use of composite time trade-off and discrete choice experiment methods for the valuation of the Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS): a think-aloud study

PurposeTo identify patterns and problems in completing composite time trade-off (C-TTO) and discrete choice experiment (DCE) exercises for the valuation of the Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS) to inform the optimisation of a valuation protocol.MethodsFourteen cognitive interviews were conducted in the UK using concurrent and retrospective think-aloud and probing techniques. Each participant completed 8 C-TTO tasks and 8 DCE tasks within a computer-assisted personal interview setting. Verbal information was transcribed verbatim. Axial coding and thematic analysis were used to organise the qualitative data and identify patterns and problems with the completion of tasks.ResultsWhile participants found the tasks generally manageable, five broad themes emerged to explain and optimise the response to the tasks. (1) Format and structure: attention to the design of practice examples, instructions, and layout were needed. (2) Items and levels: underlying relationships were discovered across different combinations of levels of SWEMWBS items. (3) Decision heuristics: participants engaged in diverse strategies to assist trade-off decisions. (4) Valuation feasibility: certain states were difficult to imagine, compare and quantify. (5) Valuation outcome: the data quality was affected by participants’ discriminatory ability across states and their time trade-off decisions.ConclusionThe interviews contributed insights regarding the robustness of the proposed methods. The application of C-TTO and DCE valuation techniques was practical and suitable for capturing individual attitudes towards different mental well-being scenarios. A modified protocol informed by the results is being tested in a larger sample across the UK.

Public preferences for green infrastructure improvements in Northern New Jersey: a discrete choice experiment approach.

Significant water pollution caused by flooding due to heavy precipitation and extreme weather events has become a considerable problem in urbanized areas such as in Northern New Jersey. These cities experience heavy downpour-related contamination and water pollution when stormwater and untreated sewage are diverted through combined sewer overflow drainage systems to adjacent water bodies. Green infrastructure has proven a successful intervention method for mitigating these unintended environmental consequences. However, while the effects of CSOs and the ability of GI to reduce them are well documented, there has been considerably less study addressing public preferences and willingness to pay for GI-based solutions. As such, this study seeks to understand these facets of GI management in urbanized areas of New Jersey, focusing on Newark, Paterson, and Elizabeth townships. A discrete choice experiment method was used to analyze the willingness of residents to pay for additional CSO infrastructure through the installation of GI options such as bioretention gardens, rain barrels, and green roofs. Furthermore, study identified attributes such as secondary benefits, proximity, and water retention that respondents found the most utility in when choosing GI stormwater management interventions. We found that several attributes, including improved air quality ($58.60), increased water supply ($49.71), and closer proximity ($110.01–$125.97) had the highest utility and similarly were associated with a higher willingness to pay than other tested attributes. These findings are important in assessing the overall attitude toward these fixtures, and may be critical in crafting local policy and development, especially to address environmental equity.

Towards pro-poor and voluntary PES: assessment of willingness to pay and willingness to accept PES contract in central Vietnam

ABSTRACT This study employed Contingent Valuation and Discrete Choice Experiment methods to investigate the potential of a Payment for Ecosystem Service mechanism that incentivizes sustainable land use practices by determining the willingness of ecosystem service beneficiaries to pay for delivery of services via adoption of sustainable land use practices by upland poor, ethnic minority communities, and vice versa, the willingness of communities to adopt such practices upstream of Vu Gia river, central Vietnam. From the users’ side, 64% and 56% of pooled respondents said they are willing to pay a higher rate for water and electricity consumption, respectively, if upstream watershed management is improved. On the providers’ side, WTA was high if the conditionality is relaxed. Our findings suggest a fundamental challenge in designing PES that matches the needs of buyers and providers – a scheme that ensures ecosystem service flows but does not impose stringent rules that limit stakeholders’ participation.

Preferences in 'Jalapeño' Pepper Attributes: A Choice Study in Mexico.

Background: According to Mexican growers of ‘Jalapeño’ peppers, its commercialization is the primary limitation. Thus, consumer knowledge is critical to develop added-value strategies. The objective of this study was to identify ‘Jalapeño’ quality attributes to determine consumer preferences and willingness to pay, based on socioeconomic characteristics. Methods: A nationwide face-to-face survey was carried out using the discrete choice experiment method. The survey included 1200 consumers stratified by gender, age and region. Results: Heterogeneity analysis using the probabilistic segmentation model revealed three types of consumers: A price-sensitive segment, non-demanding consumers without specific preferences and selective consumers with a preference shifted toward specific ‘Jalapeño’ characteristics. Thus, detail-oriented producers must compete through price strategies, based on the marketplace (markets on wheels, grocery stores, or supermarkets) and through some quality attributes preferred by selective consumers. Therefore, results suggest that farmers should grow the correct varieties with appropriate agronomic management to cope consumer preferences. Conclusions: This paper contributes to the growing body of the ‘Jalapeño’ literature by explicitly investigating consumer preferences and willingness to pay for them.

Mothers' preferences and willingness-to-pay for human papillomavirus vaccines in Iran: A discrete choice experiment study.

This study aimed to identify mothers' preferences and willingness-to-pay (WTP) for human papillomavirus (HPV) vaccines (in this case, bivalent and quadrivalent) in Iran. We used a discrete choice experiment (DCE) method to present mothers with choices between two hypothetical profiles of vaccines, described by combinations of five attributes, each with two or three levels. We analyzed the DCE results using conditional logistic regression and measured WTP estimates for each attribute. Our response rate was 53.96%, while the completion rate for questioner was 93.57%. We identified protection against cervical cancer, protection against genital warts, protection duration, serious side effects, and cost to influence mothers' preferences for HPV vaccination. The relative importance for serious side effects was the highest among all attributes. Mothers' WTP for bivalent and quadrivalent HPV vaccines was in US $ -432 (US $1=IRR 42,000) and US $ 380, respectively. Quadrivalent vaccination could be the most suitable candidate for implementing the national immunization schedule. The reason is that mothers express more WTP for the quadrivalent vaccine than bivalent due to its protection against genital warts.

Pharmacists' preferences for the provision of services to improve medication adherence among patients with diabetes in Indonesia: Results of a discrete choice experiment.

Little is known about pharmacists' preferences for services to improve medication adherence in patients with diabetes in Indonesia. Identification of such preferences can provide valuable insights on suitable services from a pharmacist's perspective. This study elicits pharmacists’ preferences for services to improve medication adherence among their patients. A discrete choice experiment (DCE) method was used to survey pharmacists in all community health centres and three hospitals in Surabaya, Indonesia. Four attributes of consultation, namely duration of consultation, place of consultation, access to a pharmacist and patient copayment, and two attributes on additional services (educational and behavioural‐based services) were included. The 16 profiles generated for DCE were partially balanced and partially without overlap. A random‐effect logistic regression was used in the analysis. In total, 99 pharmacists completed the questionnaire, but only 80 were included in the study based on a consistency check. All attributes were found to determine preferences for a pharmacist service package. Pharmacists preferred a consultation with a shorter duration accompanied by flexible access to the pharmacist as well as a private consultation room and a lower patient copayment. Providing the patient with a brochure/leaflet was the most preferred additional service to help improve medication adherence. Patient group discussion and medication review were also preferred in combination with a consultation. Pharmacists' socio‐demographic background characteristics influence preferences. These findings can be considered in evaluating current practice and designing pharmacist services to help improve medication adherence among patients with diabetes.

Valuing End-of-Life Care for Older People with Advanced Cancer: Is Dying at Home Important?

Most health care systems are facing the challenge of providing health services to support the increasing numbers of older people with chronic life-limiting conditions at the end of life. Many policies focus primarily on increasing the proportion of deaths at home. This study aims to investigate preferences for care throughout the latter stages of a life-limiting illness, particularly the importance of location of care, location of death, and the use of life-sustaining measures. It focuses on preferences for the care of an older person with advanced cancer in the last 3 weeks of life. A survey using discrete choice experiment (DCE) methods was completed online by a general population sample of 1548 Australians aged 45 years and over. The experiment included 12 attributes, and each respondent completed 11 choice sets. Analysis was by a mixed logit model and latent class analysis (LCA). The most important attributes influencing care preferences were cost, patient anxiety, pain control, and carer stress (relative importance scores 0.21, 0.19, 0.14, and 0.14, respectively), with less importance given to place of care and place of death (relative importance scores 0.03 and 0.01). The model predicted that 42% would consider receiving most care in hospital better than at home (58%) holding the levels of other attributes constant across the alternatives, while 42% would consider death in hospital better than at home (58%). Three population segments with different preferences were identified by the LCA, the largest (46.5%) prioritised how the patient and carer felt as well as the pain control achieved, the next largest (28.1%) prioritised cost, and the smallest segment (25.4%) prioritised a single room when an inpatient. This study shows that investment in services to support people at the end of life would be better targeted toward programmes that improve patient and carer wellbeing irrespective of the location of care and death.

Discrete choice experiment for eliciting preference for health services for patients with ALS and their informal caregivers

BackgroundAmyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative condition with a mean life expectancy of 3 years from first symptom. Understanding the factors that are important to both patients and their caregivers has the potential to enhance service delivery and engagement, and improve efficiency. The Discrete Choice Experiment (DCE) is a stated preferences method which asks service users to make trade-offs for various attributes of health services. This method is used to quantify preferences and shows the relative importance of the attributes in the experiment, to the service user.MethodsA DCE with nine choice sets was developed to measure the preferences for health services of ALS patients and their caregivers and the relative importance of various aspects of care, such as timing of care, availability of services, and decision making. The DCE was presented to patients with ALS, and their caregivers, recruited from a national multidisciplinary clinic. A random effects probit model was applied to estimate the impact of each attribute on a participant’s choice.ResultsPatients demonstrated the strongest preferences about timing of receiving information about ALS. A strong preference was also placed on seeing the hospice care team later rather than early on in the illness. Patients also indicated their willingness to consider the use of communication devices. Grouping by stage of disease, patients who were in earlier stages of disease showed a strong preference for receipt of extensive information about ALS at the time of diagnosis. Caregivers showed a strong preference for engagement with healthcare professionals, an attribute that was not prioritised by patients.ConclusionsThe DCE method can be useful in uncovering priorities of patients and caregivers with ALS. Patients and caregivers have different priorities relating to health services and the provision of care in ALS, and patient preferences differ based on the stage and duration of their illness. Multidisciplinary teams must calibrate the delivery of care in the context of the differing expectations, needs and priorities of the patient/caregiver dyad.

Value of Life Year and Cost-Effectiveness Thresholds: The Case of Poland

Abstract Objective The objective of this article is to examine how people value two different attributes of Value of Life Year (VOLY): life expectancy and the quality of life. The results of the first VOLY estimations conducted in Poland are discussed and compared with Polish cost-effectiveness thresholds for medical treatments in the period 2008–2020. Methodology The Discrete Choice Experiment (DCE) method was used to value two attributes of VOLY: increase in life expectancy and improvement in the quality of life. Main findings The VOLY research was conducted in two populations: general and dialysis. Depending on their current health status, people value increased life expectancy and improvement in health quality differently. In light of these results, the VOLY should be differentiated. Also in the Quality Adjusted Life Year (QALY) indicator, the weights of the attributes of length and quality of life should be varied according to different states of health. A uniform cost-effectiveness threshold is not justified from the perspective of stated preferences. Cost-effectiveness thresholds based on demand-side values should be differentiated. Current Polish cost-effectiveness thresholds are overestimated compared to valuations based on stated preferences. Contributions The article presents the first estimations of two attributes of VOLY: life expectancy and the quality of life, carried out in Poland.

Eliciting preferences of professors and medical group students for evaluation methods of theoretical courses: An application of discrete choice experiment analysis.

BACKGROUND:Evaluation has become an inseparable part of education process which gives feedback to students and professors to improve education quality. This study aimed to elicit preferences of professors and students about attributes of evaluation methods in theoretical courses in Kermanshah University of Medical Sciences, Iran, in 2018.MATERIALS AND METHODS:Discrete choice experiment (DCE) method used for eliciting preferences of participants of the study. A narrative literature review and interview with eight professors and ten students conducted to determine attributes and levels of evaluation methods in the university. Furthermore, experimental design used for making final choice sets of the evaluation methods. We included 213 students and 30 professors in the study. Conditional logistic regression model performed to data analysis.RESULTS:Most of the professors (36.67%) preferred to allocate up to 30% of evolution scores to midterm examination. However, the most percentage of students (30.45%) were agree to include midterm examination up to 15% of total scores. The majority of students prefer to examination questions compromise just presented materials, while 70% of professors prefer to include additional texts for evaluation examinations. In case of quiz examination, professors in comparison with students prefer that quiz should have higher proportion of total scores. DCE analysis indicated that professors and students preferred a mix of questions in examinations. In addition, additional resources beyond what is taught in class made utility for professors and disutility for students. Quiz, also, increased the utility of an evaluation package in professors.CONCLUSION:The findings showed that there is a gap between preferences of professors and students regarding some attributes of evaluation methods such as student's discipline, examination materials, and quiz. Further studies are needed to examining other attributes of evaluation methods in theatrical and practical courses in Iran and other contexts.
