The purpose of the study is to describe the impact of oral health-related quality of life (OHRQoL) on the lives of pre-seniors and seniors living in Nova Scotia, Canada. This cross-sectional study involved 1461 participants, grouped by age (pre-seniors [45-64] and seniors [65+]) and residential status (long-term care facility [LTC] or community). OHRQoL was measured using the 14-item Oral Health Impact Profile questionnaire. Approximately one in four pre-seniors and seniors reported at least one OHRQoL impact ‘fairly/very often’. Of those residing in the community, pre-seniors (28.8%) reported significantly more impacts than seniors (22.0%). Logistic regression revealed that for the community dwelling sample, those who were dissatisfied with their teeth or dentures were 5.16 times more likely to report an impact ‘fairly/very often’, which was the strongest indicator. Among the LTC sample, those who have poor perceived mouth health were 9.87 times more likely to report an impact.

Background: Serum estradiol levels decline after menopause and the effect on mental health-related quality of life (MHR-QOL) is unclear. Objective: To determine if there is an association between endogenous serum estradiol levels and MHR-QOL in healthy postmenopausal women. Methods: This cross-sectional study used baseline Canadian data from the Mammary Prevention.3 trial. Serum estradiol was measured with liquid chromatography-tandem mass spectrometry. Outcomes for MHR-QOL were the Medical Outcomes 36-Item Short Form Health Survey (SF-36) Mental Health Inventory-5 (MHI-5), Mental Component Summary (MCS), and the Menopause-Specific Quality of Life Questionnaire (MENQOL)-psychosocial domain. Results: There were no statistically significant associations between estradiol levels and MHR-QOL in univariate analyses (n=455). Multivariable linear regression predicted statistically significant differences in MCS (R2=0.10, P=0.03) and MENQOL-psychosocial domain (R2=0.10, P=0.04), however estradiol was not a significant predictor. Conclusions: This study did not find a statistically significant association between endogenous serum estradiol levels and MHR-QOL in healthy postmenopausal women.

This thesis analyses the issue of solar access in environmentally sensitive attitudes to architecture. The primary intention of the study is to scrutinize the relationship between solar access and building form (volume) and investigate the efficiency of solar control on / by this form by means of &lsquo / solar envelope&rsquo / technique which is, first, defined by Knowles and developed in different ways in the last 30 years. Solar envelope in Knowles&rsquo / terms can be defined as the building volume resulting from shadow casting restrictions and must be recognized as a both theoretical and technical method in the form generation of any building. Similar to the concept of maximum developable volume allowed under height restrictions or floor area ratios, solar envelope is, rather, defined by solar access concerns. This method is applicable on single buildings as well as dense urban areas (residential and mix use areas) and is a supportive tool in the form generation in any stage of design. Buildings constructed without exceeding the abstract solar envelope that is constructed on the basis of solar access will be successful in the means of passive solar and low-energy design. Such a success will supply a sustainable development, which is globally discussed as a result of environmental and energy crisis. The aim of this thesis is to represent the method of constructing solar envelope, in case study, with its fundamental aspects and tools. Odt&uuml / kent residences will be the objects of this study. Results of this application will be tested with shadow maps and evaluations both for the existing situation and the proposed envelopes will be developed.

Adolescents with cystic fibrosis (CF) face unique stressors that require effective coping strategies. Although research suggests that coping may be an important moderator of adjustment to stress, previous studies have utilized generic coping measures that are not specific to the disease or context. Using the Role-Play Inventory of Situations and Coping Strategies (RISCS), a context-specific coping measure for adolescents with CF, the current study examined whether coping efficacy moderated the relationship between disease-related stress and health-related quality of life. Additionally, this study investigated the impact of two family-based behavioral interventions on adolescents’ coping skills: Behavioral Family Systems Therapy (BFST) and the Family Education Program (FEP). Although no direct effects of coping on HRQOL at baseline were found, resulted showed that effective coping buffered the negative effects of disease severity and stressor frequency on HRQOL in several domains. In addition, some evidence indicated that at the most severe end of the severity continuum, there may be thresholds at which effective coping strategies no longer exert their beneficial effects. Longitudinal models revealed that improvements in coping skills were associated with positive changes in HRQOL in different domains, depending upon treatment group. These findings highlighted the utility of using context-specific, sensitive coping measures when examining the moderating effects of coping, and the importance of identifying adolescents with poor coping skills and providing tailored interventions.

Health-Related Quality of Life (HRQOL) is an important outcomes measure in cancer and there are specific issues depending on the site, stage, treatment and patient age. Although numerous instruments are available for cancer HRQOL, most are designed for adults, some for children, but none for adolescents and young adults (AYA) who have special age-specific concerns and poor improvement in survival compared with other age groups. An existing HRQOL instrument was modified to ensure its suitability for AYA, its validity, reliability and sensitivity were tested in Australians aged 16 to 25 years old diagnosed with cancer or a blood disorder. Varni’s PedsQLTM Measurement Model (13-18 year olds) was selected, modified then administered to families recruited from haematology/oncology clinics and wards at three Sydney Metropolitan Hospitals in person or by telephone. The Memorial Symptom Assessment Scale was used to categorise participants into groups reflecting sensitivity of symptom severity (slight, moderate and severe). The instruments demonstrated excellent internal consistency reliability, making them suitable for both group and individual comparisons. Clinical validity, construct validity, and discriminant validity were demonstrated by “known-groups” analysis, exploratory factor analysis and correlations, respectively. These new versions of the PedsQL Generic Core and Cancer Module are reliable, valid and sensitive measures of HRQOL in patients aged 16-25 years diagnosed with cancer or a blood disorder. The measures will soon be available for use as outcome measures in clinical trials and clinical practice with this age cohort in Australasia and internationally.

The primary aim of this thesis was to conduct a longitudinal study, to investigate the quality of life (QOL) in a large sample of people diagnosed with colorectal cancer (CRC), immediately post-diagnosis and one-year later. Various measures were utilised to capture the multifaceted concept of QOL, including psychological distress, satisfaction with life, positive affect and cancer-related quality of life. The investigation was conducted within Lazarus and Folkman’s stress and coping framework. Specifically, this research aimed to test the utility of the stress and coping framework in the context of CRC, and to explore the role of benefit-finding within the context of the stress and coping model components. One thousand, eight hundred participants (1078 men and 722 women) with a CRC diagnosis duration of 1 to 12 months, completed a telephone interview and written questionnaire, assessing demographics, disease/treatment characteristics, threat appraisal, social support, optimism, coping, benefit-finding and quality of life domains, at approximately five- and 12-months post-diagnosis. To identify CRC-specific coping strategies, the Coping with Colorectal Cancer measure was developed in the initial study. The eight factor structure was confirmed, and the subscales (Positive Perceptual Change; Religion/Spirituality; Rumination; Acceptance; Humour; Palliative; Seeking Social Support; and Lifestyle Reorganisation) found to have reliability and preliminary criterion-related validity within the context of the stress and coping framework. As predicted, regression analyses showed that, after controlling for demographics, disease/treatment characteristics and stress/coping variables, the coping subscales uniquely predicted Time 1 QOL outcomes, with Seeking Social Support continuing to predict Time 2 Positive Affect. In the second study, the benefit-finding domains specific to those with CRC were identified, and relationships with quality of life outcomes assessed, to determine the inclusion of benefit-finding in the path model. Based on completed data from 1757 of the initial 1800 participants, confirmatory factor analyses revealed three domains of benefit-finding: Personal Growth; Interpersonal Growth and Acceptance. As hypothesised, regressions analyses found that benefit-finding domains at Time 1 was associated with Time 1 QOL outcomes, specifically, Positive Affect and Cancer-related Quality of Life (both the aggregate score and its Social/Family, Functional and Colorectal Cancer-specific Well-being subscales). Time 1 Personal Growth also predicted Time 1 Psychological Distress. After controlling for Time 1 Positive Affect, Personal Growth continued to predict Time 2 Positive Affect. The final study drew on the results of the first two studies, which informed the coping strategies and benefit-finding domains to be included in regression analyses initially, and then, structural equation modelling. The final study included 1276 complete data sets of the initial 1800 participants. Parameters of the initial hypothesised model of the stress and coping framework, including relationships with benefit-finding (based on empirical findings) failed to fit the model to the data. After several revisions, the analysis revealed that the final model fit the data, where stress, coping and benefit-finding accounted for 63% of the variance in Time 1 QOL. The model showed that threat appraisal, coping resources, avoidant coping and benefit-finding directly impacted on Time 1 QOL, while threat appraisal, social support and approach coping directly impacted on benefit-finding. In this study, the approach coping strategies included in the path model could also be conceptualised as meaning-based coping strategies, as they appeared to facilitate a meaning-making process. However, benefit-finding, which some researchers have suggested is also a meaning-based coping strategy, had differential relationships with stress, coping and outcome variables, compared with the approach coping strategies. These results indicate that benefit-finding is an empirically distinct construct in the context of CRC. Finally, in this study, the impact of stress, coping and benefit-finding on Time 2 QOL, was indirect, being mediated by Time 1 QOL outcomes. The accumulated findings of these three studies have extended the cancer coping and benefit-finding research by revealing new relations between stress, coping and benefit-finding and QOL in a mixed-gender, older population with CRC. There are implications for measurement of, and theory building around benefit-finding. Finally, these studies inform the development of clinical interventions to enhance the quality of life in the short- and longer-term for individuals diagnosed with CRC.
