Attitudes to genetically modified food over time: How trust in organizations and the media cycle predict support.

This research examined public opinion toward genetically modified plants and animals for food, and how trust in organizations and media coverage explained attitudes toward these organisms. Nationally representative samples (N=8821) over 10 years showed Australians were less positive toward genetically modified animals compared to genetically modified plants for food, especially in years where media coverage was high. Structural equation modeling found that positive attitudes toward different genetically modified organisms for food were significantly associated with higher trust in scientists and regulators (e.g. governments), and with lower trust in watchdogs (e.g. environmental movement). Public trust in scientists and watchdogs was a stronger predictor of attitudes toward the use of genetically modified plants for food than animals, but only when media coverage was low. Results are discussed regarding the moral acceptability of genetically modified organisms for food, the media's role in shaping public opinion, and the role public trust in organizations has on attitudes toward genetically modified organisms.

Predicting intention to biobank: a national survey.

BACKGROUND: The success of human population biobanks are dependent on the publics' willingness to participate. This research aimed to determine those factors important in determining the public's intention to donate a biological sample to a publicly funded biobank, and allow that sample to be linked with medical records. METHODS: A national sample of 1000 Australians was surveyed via telephonic interviews. Questions included the reported likelihood that respondents would participate in biobank research, ratings of trust in biobanks, beliefs that biobank research will lead to improved health care and general ratings of comfort with blood taking and DNA analysis. RESULTS: The sample reported a high level of trust in university biobanks, a strong belief that biobank research will lead to improved health care and a strong willingness to participate in biobank research. Using structural equation modelling, trust in the biobank was found to be the most important determinant of intention to participate in biobank research, followed by general comfort with blood taking and DNA analysis, belief in health-care benefits and higher education. Gender, age, parental status and experience of genetic conditions were not significantly associated with intention to participate. CONCLUSIONS: Australians are generally willing to participate in biobank research, and this is strongly determined by trust. While benefit beliefs and comfort with research are also relevant, higher trust was associated with intention regardless of these factors, suggesting reasons other than concern for improved health care are important in determining the publics' willingness to participate in biobank research.

Understanding the impact of commercialization on public support for scientific research: is it about the funding source or the organization conducting the research.

This research examines the influence of commercialization on support for scientific research. It compares the effects of the funding source with the type of organization on public support for stem cell research. Using a national Australian telephone survey (n = 1000), the results reveal that support drops significantly when scientific research is funded by private rather than public interests, and even more so when it is conducted in a private company rather than a public university. Respondents' preference for university research was enhanced if they trusted universities, distrusted major companies and believed that the research would be beneficial. A preference for public funding was also associated with lower trust in companies and a belief that the research would benefit people. Implications of these results are discussed in relation to the challenge of maintaining public support in an increasingly commercialized research environment.

Identifying the nature and extent of public and donor concern about the commercialisation of biobanks for genomic research.

Various forms of private investment are considered necessary for the sustainability of biobanks, yet pose significant challenges to public trust. To manage this tension, it is vital to identify the concerns of relevant stakeholders to ensure effective and acceptable policy and practice. This research examines the aspects of commercialisation that are of most concern to the Australian public (n = 800) and patients who had donated their tissue to two large disease specific (cancer) public biobanks (n = 564). Overall, we found a commercialisation effect (higher support for public relative to private) in relation to funding, research location and access to stored biospecimens. The effect was strongest for research locations and access compared to funding. A latent class analysis revealed the pattern of concern differed, with the majority (34.1%) opposing all aspects of commercialisation, a minority supporting all (15.7%), one quarter (26.8%) opposing some (sharing and selling tissue) but not others (research locations and funding), and a group who were unsure about most aspects but opposed selling tissue (23.5%). Patient donors were found to be more accepting of and unsure about most aspects of commercialisation. Members of the (general) public who were motivated to participate in biobanking were more likely to oppose some aspects while supporting others, while those who indicated they would not donate to a biobank were more likely to oppose all aspects of commercialisation. The results suggest that approaches to policy, engagement and awareness raising need to be tailored for different publics and patient groups to increase participation.

Public opinion and trust in scientists: the role of the research context, and the perceived motivation of stem cell researchers.

This research examined why the public may be less supportive of stem cell research when conducted in a private compared to public research context. A representative sample (n = 403) of Australians who were exposed to information relating to privately funded scientists were significantly less likely to approve of stem cell research than those who were presented with a scenario of scientists working within a publicly funded University (n = 401) and a control condition (n = 404). Mediation analyses revealed that the decrease in approval was primarily associated with the tendency of privately funded scientists to be trusted less than their publicly funded counterparts. Public trust in University scientists was also found to be higher than that of private scientists because publicly funded scientists were perceived to be motivated more by benevolence, and more likely to produce benefits that will be accessible to the public. While private scientists were perceived to be more self interested than public scientists, perceived self interest did not explain the decrease in trust. There were also no significant differences across research contexts for the perceived competence of scientists or the likelihood that stem cell research would result in cures for diseases. The implications of these results are discussed in relation to the possible decrease in public trust that may occur alongside the increasing privatization of academic enquiry, and particularly controversial scientific research.

Nanotechnology in Dutch science cafés: Public risk perceptions contextualised.

Understanding public perceptions of and attitudes to nanotechnology is important in order to understand and facilitate processes of dialogue and public participation. This research quantitatively analysed risk perceptions and attitudes of Dutch science café participants (n = 233) and compared these with members of the Dutch public (n = 378) who had not attended a café but were interested in science and technology as well. A qualitative analysis of the meetings contextualised and enriched the quantitative findings. Both groups shared similar key attitudes and were positive about nanotechnology while the Dutch café participants were even more positive about nanotechnology than the group of non-participants. The perception that nanotechnology would lead to risk applications was only predictive of attitudes for the non-participants. The qualitative analysis showed that café participants and speakers considered discussion of the risks, benefits and related issues important. Further research could investigate how science cafés can play a role in the science-society debate.

Community engagement for big epidemiology: deliberative democracy as a tool.

Public trust is critical in any project requiring significant public support, both in monetary terms and to encourage participation. The research community has widely recognized the centrality of public trust, garnered through community consultation, to the success of large-scale epidemiology. This paper examines the potential utility of the deliberative democracy methodology within the public health research setting. A deliberative democracy event was undertaken in Tasmania, Australia, as part of a wider program of community consultation regarding the potential development of a Tasmanian Biobank. Twenty-five Tasmanians of diverse backgrounds participated in two weekends of deliberation; involving elements of information gathering; discussion; identification of issues and formation of group resolutions. Participants demonstrated strong support for a Tasmanian Biobank and their deliberations resulted in specific proposals in relation to consent; privacy; return of results; governance; funding; and, commercialization and benefit sharing. They exhibited a high degree of satisfaction with the event, and confidence in the outcomes. Deliberative democracy methodology is a useful tool for community engagement that addresses some of the limitations of traditional consultation methods.

The impact of commercialisation on public perceptions of stem cell research: exploring differences across the use of induced pluripotent cells, human and animal embryos.

The development of pluripotent cells that enable stem cell research (SCR) without destroying human embryos is now a leading priority for science. Public and political controversies associated with human embryonic SCR experienced in the recent past should be alleviated if scientists no longer need to harvest cells from human embryos. This research suggests however additional issues needing attention in order to gain the public's trust and support: the use of mouse embryos and the commercialisation of research. Using a representative sample of 2,800 Australians, and an experimental telephone survey design, this research compared levels and predictors of public support for stem cell research across three cell source conditions: human embryo (HE), mouse embryo (ME) and induced pluripotent cells (iPSCs). The results revealed that the public were significantly more likely to support research using iPSCs than HE and ME cells and public compared to private research (regardless of the cell source). There was no significant difference in support for HE compared to ME research, but the former was viewed as more likely to lead to accessible health care benefits and to be associated with more trustworthy scientists. The results of a multimediation structural equation model showed that the primary reason support for SCR significantly dropped in a private compared to public context (i.e., the commercialisation effect) was because public scientists were trusted more than private scientists. This effect was consistent across all three SCR materials, suggesting that the use of mouse embryos or even iPSCs will not reduce the publics' concern with commercialised science. The implications these results have for public acceptance of stem cell and animal research are discussed in relation to possible solutions such as increasing public awareness of the regulation of animal research and benefit sharing.

Examining the psychological pathways to behavior change in a group-based lifestyle program to prevent type 2 diabetes.

OBJECTIVE: To examine the psychological process of lifestyle change among adults at risk for type 2 diabetes. RESEARCH DESIGN AND METHODS: A randomized control trial in which 307 volunteers (intervention, n = 208; wait control, n = 99) diagnosed with prediabetes completed a six-session group-based intervention to promote healthier living. Participants' motivation to change, diet and exercise self-efficacy, mood, knowledge about diabetes, activity levels, healthy eating, waist circumference, and weight were assessed before and after the program. RESULTS: Participation in the program was associated with significant increases in healthy eating and physical activity, reductions in waist and weight, and improvements in motivation, positive mood, self-efficacy, and knowledge. Examination of the pathways to lifestyle change showed that the educational aspect of the program increased activity levels because it increased diabetes knowledge and improved mood. Eating behavior was not mediated by any of the psychological variables. Improvements in diet and physical activity were, in turn, directly associated with changes in weight and waist circumference. CONCLUSIONS: Although the program significantly improved motivation, self-efficacy, and mood, its impact on knowledge uniquely explained the increase in physical activity. Group-based programs that are tailored to lifestyle behaviors may provide a cost-effective method of diabetes prevention, but more research is needed to explain why they improve healthy eating.

Can the onset of type 2 diabetes be delayed by a group-based lifestyle intervention? A randomised control trial.

This study was a randomised control trial with a waiting control group. It was designed to evaluate the effectiveness of a 6-month, group-based diabetes prevention programme, The Healthy Living Course and assess whether participation in the programme led to changes in modifiable risk factors for type 2 diabetes among an already at-risk pre-diabetic population. Individuals designated at risk for diabetes by their general practitioners (GPs) were screened using an Oral Glucose Tolerance Test. Volunteers (N = 307) with pre-diabetes were assigned to an intervention or wait-control group in the ratio of approximately 2 : 1. The sample was pre-tested on biochemical, anthropometric and self-report behavioural, cognitive and mood variables and post-tested either at the end of the educational/support-based lifestyle programme or the end of the wait period. The intervention group significantly improved their diabetes knowledge, motivation to change, positive affect, healthy eating and activity levels and showed significantly greater reductions in weight, body mass index, waist circumference, diastolic blood pressure and fasting plasma glucose in comparison with controls. The intervention group also changed their diagnostic status from pre-diabetes to non-diabetes at a greater rate than the wait group (43% vs. 26%) who received standard care from their GPs.

Public perceptions of Australia's doctors, hospitals and health care systems.

OBJECTIVE: To assess public perceptions of Australia's doctors, hospitals and health care systems. DESIGN AND PARTICIPANTS: A cross-sectional national telephone survey of a random sample of 800 Australian adults in August 2007. MAIN OUTCOME MEASURES: Ratings of subjective trust in health care providers, public and private hospitals, private health insurers and Medicare; attitudinal ratings for the current health care system, and public and private health care systems. RESULTS: Australians reported high trust in doctors (general practitioners more than specialists), low trust in alternative practitioners, moderate trust in hospitals (private more than public), and greater trust in Medicare than in private health insurers. Older adults had the greatest trust in physicians, hospitals and Medicare, but all age groups held similar attitudes toward public and private health care systems. Support for the current health care system with its mix of public and private funding was moderately strong, but all respondents reported weak pro-private attitudes and very strong pro-public attitudes. CONCLUSIONS: Public perceptions of Australian medical professionals, institutions and systems are generally positive. This sample did not endorse an individual user-pays private health system, but strongly favoured a universal public health system that is collectively funded by the public purse.
