PURPOSE: Studies on healthy lifestyle interventions in survivors of colorectal cancer have been disappointing, demonstrating only modest changes. This study aims to quantify people's preferences for different aspects of dietary intervention. METHOD: A best-worst discrete choice experiment was designed and incorporated into a questionnaire including participants' characteristics and a self-assessment of lifestyle. RESULTS: The response rate was 68% and 179 questionnaires were analysed...

In discrete choice experiments, patients are presented with sets of health states described by various attributes and asked to make choices from among them. Discrete choice experiments allow health care researchers to study the preferences of individual patients by eliciting trade-offs between different aspects of health-related quality of life. However, many discrete choice experiments yield data with incomplete ranking information and sparsity due to the limited number of choice sets presented to each patient, making it challenging to estimate patient preferences...

BACKGROUND: Expanding vaccination programs for the older population might be important as older adults are becoming a larger proportion of the general population. The aim of this study is to determine the relative importance of vaccine and disease specific characteristics and acceptance for Dutch older adults, including pneumococcal disease, herpes zoster, pertussis vaccination, and influenza vaccination. METHODS: A discrete choice experiment was conducted to generate choice data that was analyzed using a mixed multinomial logit statistical model...

BACKGROUND: Vaccination is an effective way to prevent infectious diseases. Most studies analysed people's vaccine decisions, but few studies have analysed the effects of convenience such as immunisation schedule and distance and the quality of vaccination service on vaccination uptake. OBJECTIVE: The aim of this paper was to investigate adults' preferences for convenience and quality of vaccination service, calculate the private economic benefit from convenience (vaccination schedule and distance) and quality, and predict the uptake rate for different vaccine scenarios...

The purpose of this article is to explore whether any differences exist between the general population and patient based preferences towards EQ-5D-5L defined hypothetical health states. The article discusses the role of adaptation and self-interest in valuing health states and it also contributes rigorous empirical evidence to the scientific debate on the differences between the patient and general population preferences towards hypothetical health states. Patient preferences were elicited in 2015 with the EQ-5D-5L questionnaire using time trade-off and discrete choice experiment design and compared to the Spanish general population preferences, which were elicited using identical methods...

BACKGROUND: As more studies report on patient preferences for diabetes treatment, identifying diabetes outcomes other than glycated hemoglobin (HbA1c) to describe effectiveness is warranted to understand patient-relevant, benefit-risk tradeoffs. OBJECTIVE: The aim of the study was to evaluate how preferences differ when effectiveness (glycemic control) is presented as long-term sequela (LTS) risk mitigation rather than an asymptomatic technical marker (HbA1c). METHODS: People with type 2 diabetes and using insulin (n = 3160) were randomly assigned to four self-administered, discrete-choice experiments that differed by their presentation of effectiveness...

BACKGROUND: The national newborn bloodspot screening programs (NBSPs) are continually expanding to screen for more conditions. OBJECTIVES: To quantify parents' preferences for information and the way in which this is provided in example NBSPs. METHODS: A hybrid choice experiment, combining a conjoint analysis and a discrete choice experiment, was designed. A sample of current and future parents between the ages of 18 and 45 years was identified via an Internet panel...

Objectives.: To estimate the preferences of osteoporotic patients for medication attributes, and analyse data from seven European countries. Methods.: A discrete choice experiment was conducted in Belgium, France, Ireland, the Netherlands, Spain, Switzerland and the UK. Patients were asked to choose repeatedly between two hypothetical unlabelled drug treatments (and an opt-out option) that varied with respect to four attributes: efficacy in reducing the risk of fracture, type of potential common side effects, and mode and frequency of administration...

BACKGROUND: Food allergen labeling is an important tool to reduce risk of exposure and prevent anaphylaxis for individuals with food allergies. Health Canada released a Canadian food allergen labeling regulation (2008) and subsequent update (2012) suggesting that research is needed to guide further iterations of the regulation to improve food allergen labeling and reduce risk of exposure. OBJECTIVE: The primary objective of this study was to examine consumer preferences in food labeling for allergy avoidance and anaphylaxis prevention...

OBJECTIVE: To assess the feasibility and validity of using a discrete choice experiment format to elicit health preferences in adolescents by comparing illogical choices and choice-blindness rates between adults and adolescents; and to explore the relationship between personality traits and health-state choices. METHODS: A convenience sample of adults and adolescents (12 to 17 y old) were recruited from around Chicago, USA. A personality inventory was administered, followed by pairwise comparisons of 6 health-state scenarios which asked each candidate to select their preferred choice...

Rats were trained under a discrete-trials adjusting-magnitude schedule in which a response on lever A delivered either a larger or a smaller reinforcer (qA1 and qA2) with equal probability, while a response on B delivered a reinforcer whose size qB was adjusted according to the rats' choices. When A was preferred in a given block of trials, qB was increased in the following block; when B was preferred, qB was reduced in the following block. The oscillating changes in qB, analysed by the Fourier transform, could be described by a power spectrum with a dominant period of about 50 trial blocks...

PURPOSE OF REVIEW: The Assessment of Spondyloarthritis International Society (ASAS) axial spondyloarthritis (axSpA) classification criteria marked a major step forward in SpA research, distinguishing axial from peripheral disease, and allowing earlier identification through MRI. This facilitated all aspects of research including epidemiology, therapeutics and patient outcomes. RECENT FINDINGS: The ASAS axSpA classification criteria have been applied broadly in research, and were validated in a recent meta-analysis of international studies...

We provide a user guide on the analysis of data (including best-worst and best-best data) generated from discrete-choice experiments (DCEs), comprising a theoretical review of the main choice models followed by practical advice on estimation and post-estimation. We also provide a review of standard software. In providing this guide, we endeavour to not only provide guidance on choice modelling but to do so in a way that provides a 'way in' for researchers to the practicalities of data analysis. We argue that choice of modelling approach depends on the research questions, study design and constraints in terms of quality/quantity of data and that decisions made in relation to analysis of choice data are often interdependent rather than sequential...

BACKGROUND: There is a traditional tension in public policy between the maximization of welfare from given resources (efficiency) and considerations related to the distribution of welfare among the population and to social justice (equity). The aim of this paper is to measure the relative weights of the efficiency- and equity-enhancing criteria in the preferences of health policy-makers in Israel, and to compare the Israeli results with those of other countries. METHODS: We used the criteria of efficiency and equity which were adopted in a previous international study, adapted to Israel...

PURPOSE: Patient treatment preferences are increasingly being used to inform health care decision making. This discrete choice experiment assessed how men perceive the risks and benefits of hypothetical treatment options for metastatic castrate-resistant prostate cancer (mCRPC). METHODS: Treatment attributes for inclusion were identified through a review of the literature and product labels. Expert interviews confirmed clinical appropriateness and patient relevance of the attributes, which included effectiveness (delay in months before chemotherapy), steroid use, possible drug interactions (additional hospital visits for monitoring), fogginess (effects on cognition and memory), fatigue (extreme tiredness), food restrictions, and bone pain...

Studies of racial residential attainment show an intergenerational transmission of racial contexts from youth to adulthood, but it is unclear why this transmission is so robust. It is possible that experiences in racial contexts during youth have lasting effects on neighborhood selection in adulthood, but evidence for this claim has come from research using statistical methods that suffer from problems of ecological dependence and conflation of other neighborhood characteristics. In this study, we address these limitations using mixed-logit models, a form of discrete choice analyses, allowing us to control for differences across metropolitan areas and for multiple characteristics of neighborhoods that may affect the selection of destination neighborhoods...

Recent research has begun to investigate the impact of different formats for rational numbers on the processes by which people make relational judgments about quantitative relations. DeWolf, Bassok, and Holyoak (Journal of Experimental Psychology: General, 144(1), 127-150, 2015) found that accuracy on a relation identification task was highest when fractions were presented with countable sets, whereas accuracy was relatively low for all conditions where decimals were presented. However, it is unclear what processing strategies underlie these disparities in accuracy...
