With the rapidly ageing global population, there will be increased demand on informal older carers, who provide important roles in supporting older adults to live longer in their own homes. Depression in older carers is a well-known adverse outcome, however there is lack of consistent knowledge concerning factors associated with this outcome. The research reported in this thesis therefore investigated factors associated with depressive symptoms in a sample of older carers living at home with the older adults with whom they were caring for (the care-recipient, CR). This study differs from previous work in that a variety of different, but clinically relevant factors have been investigated. A convenience sample of 202 older carers were assessed cross-sectionally on their demographic characteristics, health measures, depressive symptoms, personality, attitudes to ageing, and CR factors (CR diagnosis and the hours spent caring). The cut-off score on the Geriatric Depression Scale (GDS-15) of ≥5 was used to delineate “depressed” and “non-depressed” carers, and a comparison of these characteristics was made between the 87 depressed, and 115 non-depressed carers. Female gender, but no other demographic factors were associated with a higher number of depressive symptoms. The CR diagnosis was not an independent factor associated with depressive symptoms. Higher levels of Neuroticism and more negative attitudes to ageing in the carers were associated with depressive symptoms. Depressed carers had worse physical health, participated in increased amounts of domestic physical activity (PA), but similar amounts of leisure-PA, compared to non-depressed carers. The regression analyses demonstrated that higher levels of Neuroticism, increased hours spent caring, and possibly increased amounts of domestic-PA, were independent factors associated with depressive symptoms. The findings of this study highlight the importance of carer-related factors when identifying risk factors for depressive symptoms in older carers. The clinical implications of this study, particularly that increased hours of care are a risk factor for depressive symptoms, suggest that in order to potentially reduce the risk of developing depression, older carers should be encouraged to “share the care” – that is the support of the CR should be preferably spread among more than one person, whether this be among other family members, and/or formal care services. Thus, being able to access support services such as “Home Help”, and respite is important. This approach may not be supported by the principles behind the current Victorian Active Services Model, which encourages self-reliance and enablement. Clinicians have an important role to encourage older carers to accept help, but this needs to be individually tailored, taking into account the carers’ personality structure.

Background and aim: Bipolar disorder is a challenging and usually chronic illness associated with occupational and social consequences that affect the lives of both the person and those who care for them. Family members and friends with a primary role in supporting an adult with bipolar disorder (caregivers) are at risk of caregiver burden, depression and health problems. However, there is little evidence-based information to guide caregivers in ways to provide helpful support and maintain their own wellbeing. Thus, the aim of this project was to develop an easily accessible resource with relevant and useful information and suggestions for caregivers. Methods: The project was divided into two phases. In the first phase a Delphi consensus study was conducted with expert clinician, caregiver and consumer panel members to establish what information and suggestions to include in guidelines for adult caregivers of adults with bipolar disorder (N=143). In the second phase of the project, a web-based version of the guidelines www.bipolarcaregivers.org was developed to make this information easily accessible over the Internet. A formative evaluation of the website was conducted to establish the relevance and usefulness of the information to caregivers and how it could be improved. This involved an initial online survey for visitors to the website (N=536) and a more detailed follow-up email feedback survey, sent to interested caregivers of adults with bipolar disorder a month later (N=121). Results: There was mostly high consensus about what to include in the guidelines between the different Delphi panels. Out of a total of 626 survey items rated by the Delphi panels over three survey rounds, 537 (86%) were included in the guidelines. In the evaluation study, the majority of caregiver visitors who completed the initial feedback survey (97%) reported thinking that the information on www.bipolarcaregivers.org was “very useful” or “useful”. Similarly, between 86.4%-97.4% of caregivers who responded to the follow-up survey rated the information they read as “very useful" or “useful”. Nearly 93% found the information relevant and all participants said it gave them the impression that others were going through similar experiences. Over two thirds reported using the sections on providing support and working with the person to manage the illness and gave concrete examples of how they implemented the guidelines. Nevertheless, despite the overall positive results, qualitative feedback suggested practical ways the website could be further refined. Discussion: This project resulted in a publicly accessible information resource www.bipolarcaregivers.org that was reported to be relevant and useful by most of the users in the evaluation study. The website includes brief information summaries and a PDF of the guidelines that can easily be printed. The guidelines have been translated into booklets in Portugal and Brazil. According to Google Analytics, traffic to the website continues to increase. Www.bipolarcaregivers.org may form an initial step in providing basic information to caregivers caring for an adult with bipolar disorder. Those who care for people with more severe and complex illness presentations might benefit from additional support and training to cope with their caregiving role. Similarly, more detailed or tailored information and support may be suitable for caregivers who are already very experienced or well informed. A strength of this project is its consideration of the views of stakeholders and careful comparison and integration with the research literature. Future studies could combine stakeholder involvement with more rigorous evaluation of www.bipolarcaregivers.org and its long-term effect on caregiver and consumer outcomes. If funds become available, the website could be made more interactive to enhance learning of information and skills, and offer more tangible and tailored support.
