Mental health has a long history of proving to be a tough concept to define. Multiple forms of knowledge and representation seek to inform as to the nature of mental health, all contributing to the production of immense complexity as to the experience of living with mental health difficulties. This thesis sets out to explore this, by getting as close as possible to mental health service users' actual experiences. A range of forms of knowledge that pertain to inform as to service users' experiences are explored, prior to analysing a corpus of interviews with service users. These are analysed through the development of a Deleuzian Discourse Analysis. Service users' experiences are analysed in terms of the relation between discursive and non-discursive factors, which include forms of mainstream psychiatric discursive practice, such as the application of diagnostic criteria and administration of treatments, along with how such practices are experienced in non-discursive dimensions of service user embodiment and space. The challenges facing service users are seen to operate around identity and control in relation to forms of psychiatric knowledge, along with presenting particular problems with regard to how user embodiment is felt, primarily in relation to psychiatric medication, and how these are driven into the production of service user spaces, i.e. day centres. Finally, a politics of affectivity is offered, as a way to unfold the complexity of service user experience, and to emphasise the existence and potential for change that can be gained through deterritorialising mental health.

Abstract The aim of this cross-sectional controlled study was to determine frequent attenders' chronic diseases and their reasons for encounter in primary health care. Furthermore, the study aimed to determine the associations of social, psychological and family factors with frequent attendance in a Finnish health centre. Patients who made eight or more annual visits to physicians in the health centre during one year were defined as frequent attenders (FA). All the FAs during 1994 (N=304) and 304 randomly selected age- and sex-matched controls constituted the study population. The data were collected from annual statistics, medical records and postal questionnaires. Over one third of the study population was interviewed. International Classification of Primary Care (ICPC) was used to determine the reasons for encounter and Symptom Checklist - 36 (SCL-36) to assess the psychological distress. Toronto Alexithymia Scale -20 (TAS-20) was used as a measure of alexithymia and Whiteley Index (WI) to determine hypochondriacal beliefs. The results showed that 4.7% of the whole population aged 15 years or older in Oulainen were FAs. They accounted for 23.5% of all visits made within the respective age group. The mean age of the FAs was 49.8 years. Over two thirds of them were female. The FAs had lower basic education and occupational status than the controls. The FAs visited physicians in the health centre mostly for reasons related to the musculoskeletal, respiratory and digestive systems. There appeared to be more chronic diseases among the FAs than among the controls. The FAs had over three times more mental disorders than the controls. The interviewed FAs had significantly more psychological distress, somatization and hypochondriacal beliefs than the controls. The risk of frequent attendance was higher in the older family life cycle phases than in the younger family life cycle phases. Multivariate analyses showed chronic somatic disease and hypochondriacal beliefs to be risk factors for frequent attendance. Concurrence of somatization and hypochondriacal beliefs increased the risk to be a FA. As a conclusion, the results emphasize the need to consider the FAs' own bodily concerns expressed as hypochondriacal beliefs when managing them. Furthermore, the study implicates a need to integrate the biomedical, psychological and social dimensions in the care of FAs in primary health care.

There has been a growing interest among policymakers in the potential role of physical activity (PA) as a strategy to mitigate the challenges associated with an aging population, specifically the potential pressures on the health care system presented by an increasing need and demand for long term management of chronic health conditions. In this dissertation, the relationship between PA and health service utilization among older adults and the role of PA in reducing health services utilization in this population is examined via two studies. Study 1: The purpose of Study 1 was to examine relationships between LTPA and health services utilization in a nationally representative sample of community-dwelling adults aged 50 years and older. Methods: This study involved a secondary analysis of data from the Cycle 3.1 of the Canadian Community Health Survey. The analysis was restricted to individuals aged 50 years and older, resulting in an unweighted sample of 56,652 adults (48%M; 52%F; mean age 63.5±10.2 years), stratified a priori into three age groups (50 – 64 years, 65 – 79 years, 80 years and older). Self-reported use of general physician (GP) services, specialist physician services and hospital services for the 12-month period prior to the survey were the outcomes of interest. The main independent variable of interest was self-reported LTPA for a 3-month period prior to the survey. A comprehensive set of predisposing, enabling, and health need factors associated with health services utilization were included as control variables in all analyses. Separate multiple logistic and negative binomial regression models were used to assess the association between LTPA and each dichotomous and count-based dependent variable, respectively. Bootstrap re-sampling procedures were applied in all regression analyses. Results In the 50-64 year age group, active individuals were 27% less likely to report any contact with a GP (OR=0.73; p<.001) and had 8% fewer GP consultations (IRR=0.92; p<.01) than their inactive counterparts. Among 65 to 79 year olds, active respondents were 18% less likely than their inactive counterparts to have had an overnight hospitalization in the previous 12 months (OR=0.82, p<.05). Across all age groups, higher levels of non-leisure physical activity was associated with lower health services utilization. Study 2: The purpose of Study 2 was to investigate the effects of a randomized community-based PA intervention (50+ in motion) on participants’ health service utilization and healthcare costs over a 5-year period. Methods: 50+ in motion was a randomized clinical trial comparing the effectiveness of a class-based (CB) and home-based (HB) exercise program for older adults with select chronic health conditions (hypertension, dyslipidemia, type 2 diabetes mellitus, osteoarthritis, overweight or obesity). Of the 172 participants randomized, 59 CB and 69 HB participants granted access to their administrative health data. Data pertaining to GP and specialist physician services utilization and costs as well as hospital services utilization and costs were obtained for all consenting participants from the Saskatchewan Ministry of Health for the year prior to enrolment in the 50+ in motion study through to 48-months post-randomization, for a total of 5-years of data. Independent variables including demographic characteristics, physical activity, sedentary behaviour, cardiovascular endurance, functional fitness, body composition, blood pressure, and self-reported physical and mental health status were collected directly from participants prior to randomization and then annually for 4 years. Longitudinal effects of the 50+ in motion intervention on health services utilization and healthcare costs were assessed using the generalized estimating equation (GEE) approach with covariates selected for inclusion based on methods of purposeful selection. Results: There were no significant differences in health services utilization or health care costs between the CB and HB interventions until the final year of the study when the HB group had 60% more GP visits than the CB group and were 89% less likely than the CB group to be frequent users of specialist services. There were no significant differences between the randomization groups in healthcare costs. Measures of functional fitness emphasizing lower body strength, endurance and power were more consistently associated with lower health services utilization than CV endurance, body composition or physical activity. Sedentary behavior was associated with higher hospital costs, independent of physical activity, functional fitness and health status. Overall Conclusion: Taken together, the two studies in this thesis address a significant gap in the Canadian literature and provide novel insights into the relationships between PA, health and health services utilization in older adults. While further research is needed to improve our understanding of the relationships between physical activity and sedentary behaviour, physical fitness, and health services utilization, the findings presented in this thesis suggest reducing sedentary behaviour and improving functional fitness in older adults may be as important as physical activity, if not more so, in terms of potential impact on health services utilization and health care costs. For health care professionals and policymakers at all levels, the findings highlight the advantages of a multi-pronged, interdisciplinary approach to the development of public health initiatives and interventions focused on increasing PA participation and functional fitness among older adults.

Social capital can be defined as a resource found in the relationships between individuals and within the community that facilitates access to resources. Social capital may have an effect on health services utilization. Few studies have explored the impact of social capital on the propensity and frequency of general practitioner visits for immigrants. The relationship between social capital and health services use by immigrants was analyzed using a dataset consisting of socio-demographic data from the 2002 Canadian Community Health Survey linked to physician claims from the Ontario Health Insurance Program for fiscal year 2006. The results suggested that the community belonging aspect of individual social capital was associated with a decrease in the number of GP visits for immigrants. Thus, community services may substitute for formal health care for immigrants.

This study examined the potential impact on processes of care and patient outcomes upon exposure of supportive and concurrent care provided by primary care providers (PCPs) to their hospitalized patients. A secondary objective was to describe the PCPs who conduct these services, and the patients who receive them. There was a marked, observable trend that PCP visits to their hospitalized patients is on the decline (dropped 10% between 2003 and 2009). The patients who received in-hospital visits from their PCPs had more disease burden and were hospitalized longer than the control group. Patients who received and in-hospital visit from their PCP were more likely to receive home care services and PCP visits post-discharge [adjusted OR 1.20 (95% CI 1.12-1.28)]. They were also less likely to experience the composite outcome of death, hospital readmission, or emergency department visit [aOR 0.95 (95% CI 0.91-0.98)].

Adolescence is a very important transition stage between childhood and adulthood. In this stage, due to rapid change physically and mentally, adolescents are more likely to occur physical, psychological, and social problems. Therefore, providing adolescents fine health service is critical. To do so, having a better understanding of the factors associated with health service utilization can help a lot. The main purpose of this study is to understand adolescents¡¦ behavior of health service utilization. Based on Andersen¡¦s behavior model of health service utilization, this study investigated the associations of predisposing characteristics, enabling resource characteristics, and needing characteristics with health service utilization of adolescents. The data used in these analyses were drawn from students in junior high schools of Tainan Providence, of which seven schools were randomly selected and then anonymous questionnaires were distributed to all students. 2,242 of 3,591 students were collected, for a response rate of 55.39%, and the final sample was 1,989. ANOVA and t test were employed to examine health service utilization of adolescents, and multiple regression was used to investigate the factors associated with health service utilization. Several results were found in this study as follows: First, significant differences did exist among junior high students, which indicated that second graders and third graders went to see doctors more times than first graders did. Second, there were 21% and 12% of respondents with experience of hospitalization and operation respectively. Students with hospitalization and operation experience utilized more health services. Third, students with national health insurance were more likely to utilize health services than those without national health insurance. Last, with regard to the relationship between self-perception of health status and health service utilization, the more respondents perceived themselves with problem of physical health or adolescent development, the more health services they utilized. In addition, the perception of emotional problem was negatively related to the utilization of health services. Several suggestions are proposed. First, establish adolescent clinics in all hospitals that are in the level of district hospitals and above to improve medical accessibility. Second, advocate the system of family physician to emphasize continuity and integrity of health care. Moreover, design appropriate clinical education for adolescents to educate them with adequate concept of health care and health utilization, making them understand the idea of health gradient to receive the right treatment in the right place. Last but not least, the health and education administration should reinforce adolescents¡¦ ability of emotional management, provide assistance for them to find out their emotional problems, and help them to receive appropriate health treatment through psychological consultation of adolescent clinics as soon as possible.
