Project description:Although corporate social responsibility (CSR) activities are common in the pharmaceutical industry, there is little empirical evidence on consumer responses to CSR practices. We investigated public awareness, preferences, and expectations regarding social contribution of the pharmaceutical industry's CSR activities, and identified the factors associated with such activities. We conducted an online survey with 1,298 respondents comprising two groups: healthy individuals (546) and patients (752). Most respondents (78%) expressed interest in CSR activities undertaken by pharmaceutical companies. However, they reported a lack of awareness and experience thereof; only 26.9% were aware of and 7.9% had experience with such activities. Among our six CSR activity categories, both survey groups showed the highest preference for the "promoting public health" (healthy group: 6.34/10; patient group: 6.37/10) and "emergency disaster relief support" (6.31 and 6.35) categories. Among sub-categories, activities related to "development of innovative drugs in untreated areas" (6.63 and 6.82) and "support for research on new drug development" (6.59 and 6.84) received the highest scores. The mean expectation score of social contribution of all CSR activities was slightly higher than the mean preference score (6.37 and 6.06, respectively). The patient group exhibited a larger difference between the highest and lowest expectation scores than the healthy group (1.11 and 0.64, respectively). The results of the regression analysis revealed that being a patient, being male, and having positive attitudes toward CSR and its expected effects significantly and positively affected public preferences regarding CSR activities. We can conclude that CSR activities with high public preference might be an effective strategy to improve public awareness of the pharmaceutical industry's CSR activities. Furthermore, the highest preference for CSR activities relates to new drug development, indicating that our society believes the pharmaceutical industry's key CSR activity should be to pursue its intrinsic mission: to fulfill unmet medical needs by developing new drugs.

Project description:The current study was designed to broaden the understanding of the attributes impacting the sensory properties of beef when consumed. Using a survey of consumers from three different geographical regions in the United States (US), we determined the impacts of three attributes on overall satisfaction in several different ways. The two main statistical methods used were an Ordinary Least Squares (OLS) model and the Conditional Logit model. Perhaps the most important finding of this study was that flavor was the largest contributor to consumer satisfaction. This finding was consistent throughout all the models. In the base model, flavor represented 59% of the satisfaction rating. Additionally, results indicated domestic beef was preferred over Australian beef by US consumers. Another important finding of the study was the impact of the demographic variables of age, income, and gender on satisfaction. The older group generally placed more emphasis on tenderness, while younger people preferred juicier beef. Males were more responsive than females for all attributes, especially tenderness. Those with higher income were more responsive to tenderness for all quality levels, but the lower income group was more responsive to juiciness. Overall, flavor had the largest impact on consumers' satisfaction level in comparison to tenderness or juiciness.

Project description:We investigate prescription drug use, and information and enrollment intentions for the new Medicare Part D drug insurance program, using a sample of Medicare-eligible subjects surveyed before open enrollment began for this program. We find that, despite the complexity of competing plans offered by private insurers under Part D, a majority of the Medicare population had information on this program and a substantial majority planned to enroll. We find that virtually all elderly, even those with no current prescription drug use, can expect to benefit from enrollment in a Part D Standard plan at the low premiums available in the current market. However, there is a significant risk that many eligible seniors, particularly low-income elderly with poor health or cognitive impairment, will make poor enrollment and plan choices.

Project description:Interest in heritage cereals is increasing among consumers, bakeries and farmers, and the trends point towards the local production of crops and connect to sustainability. The most known variety is spelt, which has opened up for old landraces such as Oland wheat. Heritage cereals have shown a higher resilience than modern varieties and have the potential to supply the market with alternative products that have an attractive cultural background. Delicious and nutritious products based on heritages cereals have a growing market potential. Consumers' attitudes and preferences to different products are affected by factors such as age, gender and education. The aim of this study was to investigate and analyse different consumer groups' awareness, attitudes and preferences toward heritage cereals. The number of respondents who participated in this study and answered the web-based questionnaire was 434. It can be concluded that most consumers are aware of heritage cereals. Geographic background had an influence, while academic background did not. Bread and pasta are the most consumed products and are regarded as the most popular future products to be based on heritage cereals. The most essential factors in bread are taste and flavour, followed by freshness and texture. The origin of the cereal and its health aspects are important; women are more concerned about the origin than men, while older consumers are more concerned about health. Older consumers are also more willing to pay extra for heritage cereal than younger consumers.

Project description:Innovations in food production and processing have largely remained "behind the scenes" for decades. The current nature of social media and calls for increased transparency regarding food results in a new landscape where consumer product demands are more important than ever, but are increasingly based on limited, or incorrect, information. One area where consumer awareness is rapidly emerging is the area of gene-edited food products. This article uses a consumer survey to gather perceptions regarding food safety, gene editing and willingness to consume for three gene-edited food products. Four factors were found to strongly influence consumer perceptions: trust in the Canadian food safety system; food technology neophobia scores; knowledge of genetics; and self-knowledge of gene editing. The survey of 497 Canadians found that 15% identified as neophobics and 12% as neophilics. The majority of participants identified as neutral. When presented with various food values, participants indicated that nutrition, price, and taste were the three most important values. A participants' willingness to consume gene-edited food products strongly correlated with neophobic and neophilic preferences, with neophobics unwilling to consume and neophilics being uncertain. The only food value that strongly affects consumer willingness to consume is the environmental impact of a products' production. Canadian consumers have a moderate to high level of trust in Canada's food safety system, but this level of trust fails to carry over to food products produced through innovative technologies; however, consumers express a higher level of trust in gene-edited technology than genetically modified technology.

Project description:ObjectivesDifferences in the process of using liver imaging technologies might be important to patients. This study aimed to investigate preferences for scanning modalities used in diagnosing focal liver lesions.MethodsA discrete choice experiment was administered to 504 adults aged 25 ?years. Respondents made repeated choices between two hypothetical scans, described according to waiting time for scan and results, procedure type, the chance of minor side-effects, and whether further scanning procedures were likely to be required. Choice data were analyzed using mixed-logit models with respondent characteristics used to explain preference heterogeneity.ResultsRespondents preferred shorter waiting times, the procedure to be undertaken with a handheld scanner on a couch instead of within a body scanner, no side-effects, and no follow–up scans (p?.01). The average respondent was willing to wait an additional 2 weeks for the scan if it resulted in avoiding side-effects, 1.5 weeks to avoid further procedures or to be told the results immediately, and 1 week to have the scan performed on a couch with a handheld scanner. However, substantial heterogeneity was observed in the strength of preference for desirable imaging characteristics.ConclusionsAn average individual belonging to a general population sub–group most likely to require imaging to characterize focal liver lesions in the United Kingdom would prefer contrast–enhanced ultrasound over magnetic resonance imaging or computed tomography. Insights into the patient perspective around differential characteristics of imaging modalities have the potential to be used to guide recommendations around the use of these technologie

Project description:This study aims to elicit consumer preferences regarding telehealth and face-to-face consultations in Australia. It used a discrete choice experiment, presenting participants with a series of hypothetical choices, and based on their responses, infer what is most important to them. Data were analysed using conditional logit regression and latent class analysis. A total of 1,025 participants completed the survey, considering four different clinical scenarios. Face-to-face contacts were, on average, preferred to either telephone or video services. However, telehealth was identified as an attractive option if it prevents significant travel and can be conducted with a familiar doctor. Participants were strongly driven by cost, particularly greater than $30. Telehealth was least preferred for situations involving a new and unknown physical symptom, and relatively more preferred for surgical follow-up. The latent class analysis demonstrates only 15.9% of participants appeared unwilling to consider telehealth. The findings of this study suggest that meeting the needs of the Australian population requires a blended approach to service delivery, with telehealth being valued in a range of clinical scenarios. Price sensitivity was evident, therefore if telehealth services can be delivered with lower patient cost, then they are likely to be attractive.

Project description:In recent decades there has been a sustained and substantial shift in human diets across the globe towards including more livestock-derived foods. Continuing debates scrutinize how these dietary shifts affect human health, the natural environment, and livelihoods. However, amidst these debates there remain unanswered questions about how demand for livestock-derived foods may evolve over the upcoming decades for a range of scenarios for key drivers of change including human population, income, and consumer preferences. Future trends in human population and income in our scenarios were sourced from three of the shared socioeconomic pathways. We used scenario-based modeling to show that average protein demand for red meat (beef, sheep, goats, and pork), poultry, dairy milk, and eggs across the globe would increase by 14% per person and 38% in total between the year 2020 and the year 2050 if trends in income and population continue along a mid-range trajectory. The fastest per person rates of increase were 49% in South Asia and 55% in sub-Saharan Africa. We show that per person demand for red meat in high-income countries would decline by 2.8% if income elasticities of demand (a partial proxy for consumer preferences, based on the responsiveness of demand to income changes) in high-income countries decline by 100% by 2050 under a mid-range trajectory for per person income growth, compared to their current trajectory. Prices are an important driver of demand, and our results demonstrate that the result of a decline in red meat demand in high-income countries is strongly related to rising red meat prices, as projected by our scenario-based modeling. If the decline in the income elasticity of demand occurred in all countries rather than only in high-income countries, then per person red meat demand in high-income countries would actually increase in 2050 by 8.9% because the income elasticity-driven decline in global demand reduces prices, and the effect of lower prices outweighs the effect of a decline in the income elasticity of demand. Our results demonstrate the importance of interactions between income, prices, and the income elasticity of demand in projecting future demand for livestock-derived foods. We complement the existing literature on food systems and global change by providing quantitative evidence about the possible space for the future demand of livestock-derived foods, which has important implications for human health and the natural environment.

Project description:ObjectiveEarly childhood parenting interventions are increasingly delivered in primary care, but parental engagement with those interventions is often suboptimal. We sought to better understand parents' preferences for the content and delivery method of behavioral health guidance in pediatric primary care and to determine the relationship of those preferences with demographic characteristics, child behavior problems, and parenting style.MethodsParticipants were 396 parents of young children recruited from primary care offices. We collected measures of parental preferences (including behavioral topics, intervention strategies, and methods of delivery) for behavioral intervention in primary care, child behavior symptoms, parenting style, and demographic characteristics. Descriptive statistics were used to identify parents' most preferred behavioral topics and intervention delivery methods. We used a hierarchical regression approach to determine whether parenting style predicted parents' preferences beyond demographic and child-level factors.ResultsNearly all parents (96%) endorsed a behavioral topic (e.g., aggression) as important. Most preferred to receive intervention during routine medical appointments. Child behavior problems correlated with parents' overall interest in behavioral guidance, but clinically significant symptoms did not differentiate interest in any single topic. Socioeconomic factors and negative parenting practices predicted some parental preferences. Notably, lax parenting generally predicted higher interest in behavioral intervention, whereas hostile and physically controlling parenting predicted lower interest.ConclusionMost parents are interested in behavioral guidance as part of primary care, but their preferences for the content and delivery of that guidance vary by known socioeconomic, child, and parenting risk factors. Tailoring intervention to parents' preferences may increase engagement with available interventions.

Project description:A fundamental assumption of the quality-adjusted life year model is mutual utility independence between life years and health status. However, this assumption may not hold for severe health states: living in a severe health state may cause disutility beyond a so-called maximal endurable time (MET). It is unknown, however, whether persons without experience of a disease, who are often used in health state valuation exercises, account for MET. Using data from 159 respondents from two convenience samples in Germany who were presented a health state description of depression, this study shows that persons without experience of depression had a lower rate of MET than persons with a history of depression. Furthermore, they had more preference reversals in case of MET, thus violating a fundamental principle of rational choice theory. While these findings suggest that severe health states should be assessed by patients rather than the community, confirmation in additional studies outside Germany and based on other health-state valuation techniques and diseases is recommended.
