The purpose of this research is to examine if and how an online education course offered by The Alzheimer Society of Ireland supports family carers of people living with dementia. The incidence of dementia is rising in Ireland and around the world. Much of the care for people living with dementia is undertaken informally by close family members. Caring for someone living with dementia can be very demanding. Family carers of people living with dementia require training and support to prepare and sustain them for the complex and changing nature of their role. This thesis considers Home Based Care Home Based Education one such online course. It is the first such Irish study of an online course aimed at supporting family carers of people living with dementia. This thesis uses a case study methodology with the online course being ‘the case’. With a convenience sampling strategy, it used multiple methods, first in the form of an anonymous online questionnaire, followed by 12 one-to-one interviews. Quantitative data was analysed using simple descriptive statistics. Qualitative data was examined using template analysis which is a form of ‘codebook’ thematic analysis. It is presented as a series of themes to answer the two research questions: (1) how does the course support dementia family carers, and (2) how can the course better support dementia family carers? Evidence suggests that the online course supports participants in a number of ways. Learners gained new knowledge and a range of practical skills through interactions with tutors, peers and course materials. However, participants offered suggestions on how to make the course more supportive to participants. Findings are presented which will be of assistance to The Alzheimer Society of Ireland as they continue to deliver online training for family carers of people living with dementia into the future.
