Abstract Background Amyotrophic 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. Methods A 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. Results Patients 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. Conclusions The 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.

Objective Virtual Consultations may reduce the need for face-to-face outpatient appointments, thereby potentially reducing the cost and time involved in delivering health care. This study reports a discrete choice experiment (DCE) that identifies factors that influence patient preferences for virtual consultations in an orthopaedic rehabilitation setting. Methods Previous research from the CONNECT (Care in Orthopaedics, burdeN of treatmeNt and the Effect of Communication Technology) Project and best practice guidance informed the development of our DCE. An efficient fractional factorial design with 16 choice scenarios was created that identified all main effects and partial two-way interactions. The design was divided into two blocks of eight scenarios each, to reduce the impact of cognitive fatigue. Data analysis were conducted using binary logit regression models. Results Sixty-one paired response sets (122 subjects) were available for analysis. DCE factors (whether the therapist is known to the patient, duration of appointment, time of day) and demographic factors (patient qualifications, access to equipment, difficulty with activities, multiple health issues, travel costs) were significant predictors of preference. We estimate that a patient is less than 1% likely to prefer a virtual consultation if the patient has a degree, is without access to the equipment and software to undertake a virtual consultation, does not have difficulties with day-to-day activities, is undergoing rehabilitation for one problem area, has to pay less than £5 to travel, is having a consultation with a therapist not known to them, in 1 weeks’ time, lasting 60 minutes, at 2 pm. We have developed a simple conceptual model to explain how these factors interact to inform preference, including patients’ access to resources, context for the consultation and the requirements of the consultation. Conclusions This conceptual model provides the framework to focus attention towards factors that might influence patient preference for virtual consultations. Our model can inform the development of future technologies, trials, and qualitative work to further explore the mechanisms that influence preference.

IntroductionCigarette packaging is a primary channel for tobacco advertising, particularly in countries where traditional channels are restricted. The current study evaluated the independent and interactive effects of cigarette packaging and health warning label (HWL) characteristics on perceived appeal of cigarette brands for early adolescents in Mexico.MethodsA discrete choice experiment (DCE) was conducted with early adolescents, aged 12–14 years (n=4251). The DCE involved a 3×25 design with six attributes: brand (Marlboro, Pall Mall, Camel), tobacco flavour (regular, menthol), flavour capsule (none, 1 or 2 capsules), presence of descriptive terms, branding (vs plain packaging), HWL size (30%, 75%) and HWL content (emphysema vs mouth cancer). Participants viewed eight sets of three cigarette packs and selected a pack in each set that: (1) is most/least attractive, (2) they are most/least interested in trying or (3) is most/least harmful, with a no difference option.ResultsParticipants perceived packs as less attractive, less interesting to try and more harmful if they had plain packaging or had larger HWLs, with the effect being most pronounced when plain packaging is combined with larger HWLs. For attractiveness, plain packaging had the biggest influence on choice (43%), followed by HWL size (19%). Interest in trying was most influenced by brand name (34%), followed by plain packaging (29%). Perceived harm was most influenced by brand name (30%), followed by HWL size (29%).ConclusionIncreasing the size of HWLs and implementing plain packaging appear to reduce the appeal of cigarettes to early adolescents. Countries should adopt these policies to minimise the impact of tobacco marketing.

The aim of this paper is to assess the relation between the character of the interpretive trail and the imposition of a charge on the entrance. This was done using the discrete choice experiment that involves eight attributes, seven of which are with three levels: the overall character of the trail, the way that the route signs are used in the terrain, the ways of providing information, the length of the trail, the way of the routing, the focus of the trail, and the price of the entrance. There is also one with two levels that involves the existence of the places for rest. The fractional factorial design was used (the orthogonal main effects plan) and the Multinomial Logit Model was used in analyzing the data. The 2,830 choices were done by random sampled visitors from eight tourist locations in the Tourist Regions of the Šumava Mts. and South Bohemia during the summer season 2012. The impact of the character of the trail was especially detected in the model. Except for that, the equipment of the trail and its length have had the fundamental impact on the choice of the trail as well. Those longer and worse equipped trails have a significantly lower degree of utility for the respondents. What is quite surprising is that the respondents refused the ecotourism elements of the interpretive trails, such as the possibility of going through the trail on horseback or the accompaniment of an expert who would provide some comments, as it is common to do this at historical attractions within those sightseeing paths.

Purpose The purpose of this paper is to answer the following research questions: which are the main drivers in the choice of a restaurant for Italian consumers? Are local, organic and GMO-free foods important attributes in the choice of a restaurant? Design/methodology/approach In order to answer the research questions, a discrete choice experiment was applied. In particular, the authors opted for the application of a latent class model to identify any differences in the behavioural structures of the various consumers. This approach is, in fact, based on the assumption that the choices of the subjects depend on observable and unobservable heterogeneity that vary with factors not directly detectable. Findings People show different preferences when they choose a restaurant. Regarding the choice experiment, the analysis of the importance of the attributes for the final choice highlights how price and service quality are always considered as the most important ones. The presence of menu with local foods, organic foods and OGM-free products is never decisive for the final choice but it is a very appreciated attribute for almost 30 per cent of consumers. This group of consumers (named local oriented) show a willingness to pay (WTP) of 11 euro for local foods, eight euro for organic products and 3.5 euro for OGM-free ingredients. For the locavores, the likelihood of choosing a restaurant offering local products is three times higher than that of a restaurant not possessing this type of certification, all other conditions being equal. Research limitations/implications Restaurant owners can differentiate their offerings also considering the local foods and organic products. On the other hand, the restaurants can become powerful marketing channels for local producers. The consumption of organic foods can be increased given the wide WTP displayed. This could positively impact in the promotion of healthier and sustainable diet. Practical implications The conditions therefore exist for developing a restaurant offer consisting of a basic menu with local foods, capable of integrating in a virtuous manner with the organic farm productions, which keep an eye on sustainable development and the wholesomeness of foods. If this virtuous process takes root in the restaurant sector, it could certainly represent an important opportunity for the agricultural producers as well, especially in the tourist areas. In order for this opportunity to materially be implemented in a development process, it is, however, necessary to develop certifications and brands capable of constituting credible guarantees for the consumer, as well as strengthening the information and communication campaigns among the younger consumers. Social implications The development of a segment of restaurants that support local foods and organic products would have positive impacts both from the social and territorial point of view. Originality/value This is the first paper that considers and evaluate the impact of local foods, organic foods and GMO-free foods in the choice of a restaurant. Findings demonstrate how the probability of choosing restaurants that offer local products, compared to the other conditions, is always higher than those focussing on organic or GMO-free products. The choice probability of the restaurant with local products is three times greater than that of a restaurant without local products, all other variables being equal.
