Imprecise definition of key terms in the "public participation" domain have hindered the conduct of good research and militated against the development and implementation of effective participation practices. In this article, we define key concepts in the domain: public communication, public consultation, and public participation. These concepts are differentiated according to the nature and flow of information between exercise sponsors and participants. According to such an information flow perspective, an exercise's effectiveness may be ascertained by the efficiency with which full, relevant information is elicited from all appropriate sources, transferred to (and processed by) all appropriate recipients, and combined(when required) to give an aggregate/consensual response. Key variables that may theoretically affect effectiveness—and on which engagement mechanisms differ—are identified and used to develop a typology of mechanisms. The resultant typology reveals four communication, six consultation, and four participation mechanism classes. Limitations to the typology are discussed, and future research needs identified.

The concept of public participation is one of growing interest in the UK and elsewhere, with a commensurate growth in mechanisms to enable this. The merits of participation, however, are difficult to ascertain, as there are relatively few cases in which the effectiveness of participation exercises have been studied in a structured (as opposed to highly subjective) manner. This seems to stem largely from uncertainty in the research community as to how to conduct evaluations. In this article, one agenda for conducting evaluation research that might lead to the systematic acquisition of knowledge is presented. This agenda identifies the importance of defining effectiveness and of operationalizing one's definition (i.e., developing appropriate measurement instruments and processes). The article includes analysis of the nature of past evaluations, discussion of potential difficulties in the enactment of the proposed agenda, and discussion of some potential solutions.

There is a growing call for greater public involvement in establishing science and technology policy, in line with democratic ideals. A variety of public participation procedures exist that aim to consult and involve the public, ranging from the public hearing to the consensus conference. Unfortunately, a general lack of empirical consideration of the quality of these methods arises from confusion as to the appropriate benchmarks for evaluation. Given that the quality of the output of any participation exercise is difficult to determine, the authors suggest the need to consider which aspects of the process are desirable and then to measure the presence or quality of these process aspects. To this end, a number of theoretical evaluation criteria that are essential for effective public participation are specified. These comprise two types: acceptance criteria, which concern features of a method that make it acceptable to the wider public, and process criteria, which concern features of the process that are liable to ensure that it takes place in an effective manner. Future research needs to develop instruments to measure these criteria more precisely and identify the contextual and environmental factors that will mediate the effectiveness of the different participation methods.

The concept of "public participation" is currently one of great interest to researchers and policy makers. In response to a perceived need for greater public involvement in decision making and policy formation processes on the part of both policymakers and the general public, a variety of novel mechanisms have been developed, such as the consensus conference and citizens jury, to complement traditional mechanisms, such as the public meeting. However, the relative effectiveness of the various mechanisms is unclear, as efforts at evaluation have been sparse. In this article, the authors describe an evaluation of a two-day "deliberative conference" on the topic of radiation dose assessment. The authors detail the evaluation framework that they adopt and describe the instruments that they have developed to determine the attainment (or otherwise) of the evaluationcriteria stipulated in that framework. They then describe the participation exercise that they have evaluated. Finally, they apply the instruments to assess the effectiveness of the exercise, and discuss the results and their implications for the conduct of evaluations and the use of this particular participation mechanism.

Recent research suggests that public attitudes toward emerging technologies are mainly driven by trust in the institutions promoting and regulating these technologies. Alternative views maintain that trust should be seen as a consequence rather than a cause of such attitudes. To test its actual role, direct as well as mediating effects of trust were tested in an attitude change experiment involving 1,405 consumers from Denmark, Germany, Italy, and the United Kingdom. After prior attitudes to genetic modification in food production had been assessed, participants received different information materials (either product‐specific information or balanced/general information about genetic modification in food production) and were asked to evaluate different types of genetically modified foods (either beer or yoghurt). The information materials were attributed to different information sources (either an industry association, a consumer organization, or a government source). After completion, perceived risk and perceived benefit were assessed, and participants indicated their trust in the information sources to which the materials had been attributed. Direct and trust‐mediated attitude change effects were estimated in a multi‐sample structural equation model. The results showed that information provision had little effect on people's attitudes toward genetically modified foods, and that perceptions of information source characteristics contributed very little to attitude change. Furthermore, the type of information strategy adopted had almost no impact on postexperimental attitudes. The extent to which people trusted the information sources appeared to be driven by people's attitudes to genetically modified foods, rather than trust influencing the way that people reacted to the information. Trust was not driving risk perception—rather, attitudes were informing perceptions of the motivation of the source providing the information.

Empirical examinations of the "social amplification of risk" framework are rare, partly because of the difficulties in predicting when conditions likely to result in amplification effects will occur. This means that it is difficult to examine changes in risk perception that are contemporaneous with increases and/or decreases in social or media discussion of the risks associated with a particular risk event. However, the collection of attitude data before, during, and after the increased reporting of the risks of genetically modified food in the United Kingdom (spring 1999) has demonstrated that people's risk perceptions do increase and decrease in line with what might be expected upon examination of the amplification and attenuation mechanisms integral to the framework. Perceptions of benefit, however, appeared to be permanently depressed by negative reporting about genetically modified food. Trust in regulatory institutions with responsibility for protecting the public was not affected. It was concluded that the social amplification of risk framework is a useful framework for beginning to explain the potential impact on risk perceptions of a risk event, particularly if that risk event is presented to the public as a new hazard occurring in a crisis context.

The repertory grid method was used to determine what terminology respondents use to distinguish between different applications of genetic engineering drawn from food- related, agricultural, and medical applications. Respondents were asked to react to fifteen applications phrased in general terms, and results compared with a second study where fifteen more specific applications were used as stimuli. Both sets of data were submitted to generalized Procrustes analysis. Applications associated with animals or human genetic material were described as causing ethical concern, being unnatural, harmful, and dangerous. Those involving plants or microorganisms were described as beneficial, progressive, and necessary. The results were validated in survey research, which indicated that general applications ofgenetic engineering were perceived as either positive or negative, whereas specific applications were more highly differentiated in perceptual terms. The results imply that the public debate about genetic engineering must take due account of the complexity of public concerns.

There is a lack of published evidence which demonstrates the impacts of public engagement (PE) in science and technology policy. This might represent the failure of PE to achieve policy impacts or indicate a lack of effective procedures for discerning the uptake by policy makers of PE-derived outputs. While efforts have been made to identify and categorize different types of policy impact, research has rarely attempted to link policy impact with PE procedures, political procedures, or the connections between them. In this article, we propose a simple conceptual model to capture this information, based on semistructured interviews with both policy makers and PE practitioners. A range of criteria are identified to increase the policy impact of PE. The role of PE practitioners in realizing impacts through their interactions with policy makers in the informal "in-between" spaces of public engagement is emphasized. However, the potential contradictions between the pursuit of policy impacts and the more traditional conceptualizations of PE effectiveness are discussed. The main barrier to the identification of policy impacts from PE may lie within policy processes themselves. Political institutions have responsibility to establish formalized procedures for monitoring the uptake and use of evidence from PE in their decision-making processes.

The risk analysis of the health impact of foods is increasingly focused on integrated risk‐benefit assessment, which will also need to be communicated to consumers. It therefore becomes important to understand how consumers respond to integrated risk‐benefit information. Quality‐adjusted‐life‐years (QALYs) is one measure that can be used to assess the balance between risks and benefits associated with a particular food. The effectiveness of QALYs for communicating both positive and negative health effects associated with food consumption to consumers was examined, using a 3 × 2 experiment varying information about health changes in terms of QALYs associated with the consumption of fish (n = 325). The effect of this information on consumer perceptions of the usefulness of QALYs for describing health effects, on risk and benefit perceptions, attitudes, and intentions to consume fish was examined. Results demonstrated that consumers perceived QALYs as useful for communicating health effects associated with food consumption. QALYs communicated as a net effect were preferred for food products associated with negative net effects on health, while separate communication of both risks and benefits may be preferred for food products associated with positive or zero net health effects. Information about health changes in terms of QALYs facilitated informed decision making by consumers, as indicated by the impact on risk and benefit perceptions as intended by the information. The impact of this information on actual food consumption choices merits further investigation.

The psychometric approach developed by Slovic and his co‐workers has been effectively used to assess risk perceptions associated with different food‐related hazards. However, further examination (using questionnaire data and partial correlation techniques) has indicated that technological hazards are highly differentiated from lifestyle hazards, in terms of both hazard control and knowledge about the hazard. Optimistic bias was also seen to vary between hazards. Further research has focused on a particular hazard, genetic engineering. Risk perceptions associated with genetic engineering are underpinned by ethical concern and questions relating to perceived need for the technology, as well as perceptions of risk or harm. However, increasing the specificity of hazard stimuli was found to alter the factor structure of underlying risk perceptions. The utility of preference mapping procedures in determining individual differences in trust in risk regulators is also discussed.
