Participatory action research (PAR) oriented by an eco-system health framework is one approach to involving marginalised peoples in their own problem solving. A PAR project during 2005-06 that engaged peri-urban farmers in Senegal using popular education documented change on environment and health perceptions and behaviour. Health as a theme took on greater importance, as farmers related good health to their ability to work and their overall productivity. Farmers came to better recognize the symptoms of pesticide poisoning and to establish more clearly the link between pesticide-related work practices and health effects. Less clear remained their recognition of symptoms and links with wastewater use practices, though malaria and parasitic infection were linked to urban agriculture. African worldviews, including notions of locus of power, were important determinants of perceived vulnerability to risks. Farmers cited fatigue as an important clue to the work-health interface and indicator of overall wellbeing. Farmers’ understanding evolved to become more dynamic, describing the complex web of environmentally-related health risk. By 2006, farmers experimented more with less toxic pest control methods, adjusted their clothing to protect their skin and mouth, and reduced some exposure pathways through improved hygiene behaviour. However, toxic pesticides continued to be used and exposure to wastewater with limited protection remained widespread. Change was dependent upon: the researcher’s deep understanding of how farmers learned; farmers’ trust in the purveyors of new information; and the clarity, consistency and relevance of messages devised. Change varied with farmers’ literacy; the language used; and the way in which tools and media were interpreted culturally and technically. The health belief model provided a partial explanation for changes in perceptions and behaviour. Social, political and economic barriers preventing change included: leaving the onus for change on farmers, diminishing the responsibility of pesticide manufacturers and governments; land tenure arrangements which reduced investment in health and environment protection; urban poverty and illiteracy; and eco-system constraints. Examination of the PAR process, its leadership, owners, tools and ideas developed, and knowledge created provided useful insight into issues of power and control.

Effective risk communication is essential in the field of health to ensure patients understand the information being presented to them by medical professionals and appreciate the level of risk involved in treatments. Cardiovascular disease, being the leading cause of death worldwide, is relevant to consider when examining risk communication in a health setting. Those afflicted with cardiovascular ailments are both high in number and exposed to information communicating risk. This research aims to identify presentation formats that are more effective communicating risk information to recovering cardiovascular patients at the University of Ottawa Heart Institute. The formats’ effectiveness is measured by gauging the population’s understanding of the material and perception of the information as it relates to risk and motivation. The research draws on Max Weber’s concept of rationality and subsequent scholars who developed social judgment theory, the heuristic-systematic model, expected utility theory, protection motivation theory, and the extended parallel process model. Utilizing an experimental research design, risk information handouts and questionnaires are distributed to, and completed by, a stratified sample of cardiovascular disease patients. Effective presentation formats are examined, and the results identify comparatively effective presentation formats for minimizing and maximizing risk perception. The results also identify presentation formats’ impact on a patient’s level of motivation to avoid / indulge in behaviours that may maximize or minimize risk. The results, synthesized herein, suggest a model (communicative cardiovascular physician-patient model of message preparation-perception), which may contribute to the effectiveness of risk communication between physicians and cardiovascular disease patients.

Consumers are becoming increasingly concerned about their foods and more particularly, the origin of their foods and the ingredients they contain. In light of the demand for additional origin information, the 100% Canadian milk branding initiative was launched in 2009 as a means of informing consumers about the origin of milk in their dairy products. The information is indicated by the presence of the 100% Canadian milk symbol on dairy products and can be characterized a form of co-branding. The literature on co-branding stipulates that co-branding can result in changed product perceptions either negatively or positively. In addition, the willingness to pay (WTP) literature stipulates that WTP is determined by product attributes and individuals’ characteristics. This thesis therefore seeks to ascertain the factors affecting consumers’ preferences and WTP for products with the 100% Canadian milk symbol. Specifically, the effects of individual characteristics such as health consciousness, patriotic values and risk perceptions on preferences for dairy products with the symbol are evaluated. Concurrently, the study explores the relationship between respondents’ knowledge of the Canadian dairy industry and WTP for the symbol. Data were gathered from a total of 1012 milk and ice cream consumers using two nationwide internet surveys. Estimations are carried out using the Multinomial Logit (MNL) and the Random Parameter Logit models (RPL). The results suggest that consumers in general have positive perceptions of milk and ice cream with the 100% Canadian milk symbol but negatively perceive store brand and organic labels. However, in some cases, combining a store brand label or organic label with the 100% Canadian milk symbol, are shown to alter consumers’ perceptions of the product. Some socio-demographic variables and individual characteristics were also found to be influential in intended purchase behaviours and WTP for milk and ice cream. The findings from this study provide information on consumers’ perceptions and attribute preferences and are expected therefore to contribute to the marketing strategies of the Canadian dairy industry as a whole.

A secondary purpose was to examine potential mechanisms through which changes in risk perception might occur. 227 college smokers evaluated one of three pamphlets, (1) a factual (i.e., primarily fact-based) smoking risk pamphlet, (2) an evaluative (i.e., primarily emotion based) smoking risk pamphlet, or (3) a control pamphlet unrelated to smoking. Among occasional smokers, NC interacted with type of risk message to influence perceptions of post-pamphlet risk for several of the risk perception outcomes examined. / ABSTRACT: Specifically, smokers lower in NC reported higher levels of perceived risk in response to the evaluative pamphlet whereas smokers higher in NC reported greater perceived risk in response to the factual pamphlet. The interaction did not predict risk perception outcomes among daily smokers. Significant changes in the mechanisms examined were not observed. Findings provide evidence that NC interacts with type of smoking risk message to influence changes in smoking-related health risk perceptions among occasional college smokers. Theoretical and practical implications are discussed. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Human civilization is failing in the fight to reduce carbon dioxide emissions and limit the impact of anthropogenic climate change. Whilst there are likely numerous reasons for this inertia, societal risk perception plays a fundamental role in influencing the speed and effectiveness of political and social action to address climate change. This study presents the psychological, sociological and cultural reasons for variations in the perceptions of risk amongst a group of climate change sceptics in Sweden. Highlighting cognitive barriers and characteristics associated with different ideological biases and worldviews. The paper concludes that people become more or less sceptical to climate change based on a variety of potentially intersectional issues. Whilst gender, age and wisdom all play a role, the social groups with which people identify, as well as individuals’ values and ideas of what constitutes an ideal society ultimately shape ones perception of risk in relation to climate change. The implications for the communication of climate science are discussed, revealing that any inclusive communication strategy will fail unless it is presented in a way that affirms rather than challenges one’s cultural identity.

The purpose of this study was to determine the factors that influence women's decisions to use hormone replacement therapy (HRT) during menopause. Using the Theory of Planned Behavior and constructs of risk perception, this study was able to explore the beliefs and attitudes of women about HRT use during menopause. The study was also able to explore how risk perception of HRT and the conditions that affect women during midlife impact their decision to use HRT during that time. Focus groups were conducted to develop the questionnaire used in the larger study. A community-based sample of women from Houston area churches participated in the study. The major theme that emerged from the focus groups was the weighing of cancer risks and the protection benefits of HRT. The most interesting factor that emerged as a barrier to HRT use was "negative publicity" and myths toward taking HRT. Results from the larger study demonstrated that the construct of attitude was the predominate predictor of intention when direct measures were used in a model to predict intention. Meaning that women's attitudes towards HRT use during menopause (whether they are safe, wise to use, good or bad, beneficial, risky, pleasant, or valuable) played a significant role in their intention. In contrast when the belief-based measures were used in the model, subjective norm and perceived behavioral control were significant predictors of intention. Meaning that the intention to use HRT was based more on the influence of their husbands, physicians, and families. This also meant that the dosage form, cost, negative publicity, family history of cancer, personal fear of developing cancer, and education about HRT would affect their intention to use HRT during menopause more than the advantages and disadvantages of using HRT (advantages such as protection from osteoporosis, relief from hot flashes; or, disadvantages such as risk of breast cancer). Finally, women's perception of risk with regards to HRT was highest for breast cancer followed by heart disease, endometrial cancer, and osteoporosis. This study found that there are many factors that may affect the decision to use HRT during menopause and that overall these factors affect women’s attitudes towards HRT and their intention to use it. / text

This study examined the perception of barriers to pro-environmental behaviour for different population segments in British Columbia. Cultural cognition scales were used to assign cultural values to participants (i.e., hierarchy-egalitarianism scale and individualism-communitarianism scale). Psychological and socio-cultural barriers were assessed using the list of dragons of inaction. Data on cultural values, perception of climate change risk, perception of barriers, frequency of pro-environmental behaviour, climate change knowledge and socio-demographic variables were collected using online surveys. Egalitarian values were correlated with greater climate change risk perception and with weaker perception of barriers to pro-environmental behaviour. Greater climate change risk perception was also associated with more pro-environmental behaviour. The effect of cultural values on barrier perception was partly mediated by climate change risk perception. These findings suggest that future research should focus on lessening the discrepancy between scientific climate change risk perception and public climate change risk perception, which can, in turn, increase the frequency of pro-environmental behaviour. / Graduate / 0768 / 0451 / lacroixk@uvic.ca

Background: African American (AA) women have a disproportionately higher prevalence of Type 2 Diabetes Mellitus (T2DM) and its related complications than Hispanics and non-Hispanic white women. Cultural practices, stigmatization, discrimination, socio-economic status, historical experiences and geographical locations have all been proposed as factors that influence the prevalence of T2DM in AA women. However, no study has explored how AA women with T2DM perceive their risk of developing diabetes complications, and how their risk perceptions impact their diabetes self -management. Purpose: The purpose of this study was to describe the perceptions that AA women diagnosed with T2DM have of their risks of developing DM complications, how their perceived risk of diabetes complications influences their DM self-management, and how the socio-cultural and economic contexts in which DM management occurs influences AA women's DM self-management behaviors. Method: A qualitative descriptive study was used to provide a comprehensive description of the perception of risk for developing diabetes complications among AA women with T2DM. A purposive sample of 10 AA women with T2DM was selected for the study. Findings: Findings revealed that the risk perception for developing DM complications influenced DM self-management among AA women with T2DM. Sociocultural and economic factors were also found to influence DM self-management among AA women with T2DM. Conclusion: This study revealed numerous factors that were associated with development of diabetes complications among AA with T2DM. However, risk perception stood out to be associated with all the factors.
