Family caregivers encounter immense negative consequences including decreased quality of life and increased rates of morbidity and mortality that stem from physical burdens, emotional distress, depression, social isolation, and loss of financial security. Although communication is an important aspect of caregiving, communication tasks are reportedly difficult for end-of-life family caregivers. The goal of this study was to explore the variety of communication stressors experienced by end-of-life family caregivers to gain insight into the communication tasks caregivers perceive as most difficult and the reasons why. Qualitative data was achieved through in-depth, face-to-face interviews with 40 caregivers currently providing care for a family member diagnosed with Alzheimer’s disease and related dementias (n=20; ADRD) and Glioblastoma (n=20; brain tumor [GBM]). A grounded theory approach was employed to gain insight into end-of-life family caregiver communication experiences. The results revealed that communication is perceived as a burden for end-of-life family caregivers. Not only does communication burden exist, end-of-life family caregivers experience immense tension and stress regarding a variety of relational contexts when communicating with the care recipient, others (family, friends), and clinicians. The results further revealed that communication burden stems from the caregiver’s attempt to negotiate between two opposing extremes: a desire to protect the patient and others versus a need to protect oneself. Thus, internal tension occurs when end-of-life family caregivers contemplate whether and how to engage in difficult conversations, and then again when following through. The presence of these contradictory tensions induced the emergence of barriers and therefore communication burden within various aspects of the end-of-life caregiver experience. Added insight into communication burden was achieved through a supplementary scale development study in a sample of ADRD and oncology end-of-life caregivers (N=263), which revealed communication burden as significantly associated with caregiver burden and quality of life. Implications for the advancement of interpersonal and health communication theory as well as practical tailored interventions targeting end-of-life family caregivers are discussed.

Research has demonstrated that problem gambling is associated with substance and alcohol abuse (Petry, Stinson, & Grant, 2005), participation in criminal activities (McCorkle, 2002; Meyer & Stadler, 1999), and involvement in the criminal justice system (NORC, 1999). This study assessed problem gambling and its relation to crime and substance use within a population in which these risk factors are compounded: Adults mandated to participate in drug and DUI courts. Results indicate that the prevalence and severity of problem gambling may be higher within this population than any other. Furthermore, the results of qualitative and quantitative analyses converged to highlight that gambling, crime and substance use are interrelated behaviors, as each may lead to and/or reinforce the other. These findings suggest that problem gambling is a salient issue among substance-abusing offenders and that resources should be dedicated to screening those involved with the criminal justice system for problem gambling, establishing evidence based best practices in the prevention and treatment of problem gambling within this population, and that such practices may incorporate components addressing gambling, crime, and substance use.

A growing body of research indicates that nature connectedness should be an important component of environmental education programs as emerging empirical evidence shows a correlation between connectedness to nature and environmentally responsible behaviour. Despite an increased interest in further examination of the human-nature relationship, research is lacking in terms of specific factors or conditions that influence nature connectedness. In this study, a mixed methods approach was employed to quantitatively assess the impact winter camping had on nature connectedness and then qualitatively determine specific components of the camp experience that influenced this sense of nature connectedness. Nineteen scouts participated on a three day winter camp at Manning Park in British Columba, Canada, where they experienced many challenges such as sleeping in quinzees (snow caves) and learned new skills such as snowshoeing. The Nature Relatedness Scale was used to assess nature connectedness in this study. A pre-test was administered a few days before the winter camp and the post-test two days afterwards. The results from the paired sample T-test show that there was a statistically significant improvement in nature connectedness following the winter camp experience. Eleven scouts were then selected to participate in semi-structured interviews with the aim of gaining insight to the specific conditions of winter camping that influenced nature connectedness. The results indicate that the location of the camp, the condition of being immersed in nature, interacting with wildlife, the positive experience of challenges, the presence of risk, and freedom from technology are all contributing factors that influenced a sense o f nature connectedness. An increased environmental awareness was also a prevalent theme which supports research suggesting that there is a positive relationship between nature connectedness and pro-environmental behaviour. It is recommended that programs with the aim of promoting nature connectedness or environmental awareness should include as many of these components as possible. Further research should alsobe conducted to confirm that these results apply also to other populations as these results cannot be generalized with a sample size of nineteen.

The thesis research examined localized socio-environmental perceptions related to amplified fresh water requirements for hydraulic fracturing and subsequent flowback disposal activities. These requirements are associated with increasing shale gas development in the Duvernay formation, located within the Kaybob region of West-central Alberta, Canada. Fresh water refers to surface and groundwater with a total dissolved solids concentration of less than 4,000 ppm. Through recourse to a mixed methods approach, combined with triangulation as a method of further validation, the research demonstrates that there exists a public sensitivity related to fresh water use in the Kaybob region. This sensitivity arises from increasing development activities in the Duvernay shale gas formation. The thesis presents conclusions and recommendations whereby industry may address stakeholder concerns, and provides advice for future research.

The intensification of Ontario’s communities through recent policies such as the Greater Golden Horseshoe Growth Plan (GGH) will reduce the amount of local natural spaces for residents. Presently many of Ontario’s youth experience the natural world primarily by visiting environmental education centres. This study used sequential exploratory mixed methods to discover the perceptions of environmental educators concerning the realities of their daily practice. The first phase of the study utilized a grounded theory approach to construct an understanding of environmental education in Ontario. The interrelated themes of increasing environmental consciousness, evaluation of programs and centres, influence of visiting adults on program effectiveness, and programming were revealed. The second phase utilized the themes derived to construct an online survey in order to measure the actual practice of environmental educators compared to their perceived best methods. The results indicate that the scarcity of effective program and institutional evaluation, ineffective communication between supervising adults, and the conflict over pedagogical aims lead to some centres potentially only achieving mediocre increases in the environmental consciousness of the participants. The need for explicit, accessible areas where youth can engage in repetitive unstructured activities in the natural world is highlighted as an area for community stakeholders to focus their efforts on if pro-environmental behaviour is a desired trait in residents.

In this thesis, I take a mixed methods approach to exploring motivations and explanations for self-control and self-control failure. In Study 1, I used quantitative, experimental methods to test predictions derived from the strength model of self-control and self-determination theory related to voluntary risk, vitality, and self-control. In Study 2, I used thematic analysis of qualitative interviews to describe how people experience self-control and self-control failure. The strength model describes self-control as a limited resource that is depleted by acts requiring executive control. When people’s self-control is depleted, they are motivated to conserve and replenish self-control resources. One way of regaining self-control may be engaging in risky activities that provide a replenishing sense of vitality. Feelings of vitality are associated with perceptions of autonomy, and may serve as an experiential barometer of self-control strength. In Study 1, I manipulated self-control depletion and risk autonomy to test whether people engage in risky choices to provide a replenishing sense of vitality. My results suggest that vitality is not a reliable barometer of self-control strength. Perceptions of autonomy appear to be a predictor of short-term self-control strength, such that forced risk is a depleting experience. Further, perceptions of autonomy were an important facet of participants’ attributions of self-control success. However, thematic analysis further suggests that experiences of self-control cannot be removed from a context of motivation and emotion. More than just short-term fluctuations in ability to resist temptation, people’s personal theories of self-control provide a long-term narrative for explaining success and failures of goal-directed striving. More than just an intra-individual construct, the social context of self-control appears to have important influences on people’s attributions for self-control and self-control failure. By combining quantitative and qualitative methods, I add to the self-control literature by providing an account of the mechanisms and experiences of self-control and self-control failure.

The current study compared participants’ ability to perform tasks using two nutrition labels: a control Nutrition Facts table of the current Canadian format (n=64), and an experimental label (n=64), identical to the control label with the exception of a footnote explaining how to interpret percent daily values. A 25% subset of participants answered questions using a think aloud technique, and data was analyzed using content analysis. The main outcome measured was ability to interpret percentages correctly, with ability to compare, define and manipulate information as secondary outcomes. No significant differences were seen in ability to perform tasks between the experimental and control conditions for any outcomes. As determined by chi square tests, higher performance was associated with higher education, being male, and report of previous Nutrition Facts table use. Verbal protocol analysis identified that interpretation of percentages was based on the meal, food type, and comparison to other foods.

Knowledge translation and exchange (KTE) is integral to the formation of evidence-informed policy. Prior to the work presented in this dissertation, a significant body of literature existed in the healthcare field regarding research-to-policy KTE; however, little was known about KTE between researchers and policymakers in the Canadian food safety system or the context-specific barriers that influence KTE. A mixed-methods approach was used, grounded in concepts from the healthcare literature, to explore Canadian food safety researchers’ KTE awareness and activities with policymakers, the barriers hindering KTE engagement and success, and timing and informational disparities between research and policy needs that may hinder KTE success. Canadian food safety researcher awareness of and engagement in KTE activities with policymakers was high. However engagement in activities identified as having the greatest potential for KTE success—i.e., collaboration with policymakers at all stages of the research process, provision of syntheses such as systematic reviews, and provision of a searchable database of research findings—was low relative to end-of-research dissemination of findings to policymakers. Several barriers were identified that limited KTE engagement and success from the researcher’s perspective, including an inability to identify relevant policymakers, high policymaker turnover, a lack of resources and support in the research organization, a perceived lack of KTE skills on the part of researchers, and an inability to break free from traditional publish-or-perish research roles. Apparent informational disconnects (i.e., research output not meeting policymakers’ apparent informational needs) were identified that may further hinder KTE and evidence-informed policymaking. While new methodologies, such as systematic review, have been adapted for food safety research, boosting researchers’ potential ability to produce policy-relevant evidence, a cultural shift must occur in research and policymaking organizations, if sustained KTE is to be successful. As well, significant future investment must be made on the part of research organizations and policymakers, if KTE barriers are to be mitigated. Future research should evaluate KTE tools (e.g., sustained linkages between researchers and policymakers, provision of syntheses, provision of access to a database of research findings) to identify specific methods that may facilitate research use in food safety policymaking. / Blake Graham Fellowship, Canadian Institutes of Health Research, Public Health Agency of Canada
