Family caregiving plays a significant role in enabling older adults to stay as long as possible in their familiar community. This concept, known as Aging-In-Place, is preferred by older adults worldwide and is advocated by government policies. According to the latest statistics, adult children account for the largest proportion of family caregivers in Hong Kong, and the demand for family caregivers is expected to escalate in the coming years. Dementia family caregivers are continuously challenged by care demands that are often highly variable and unpredictable, putting them at risk for adverse effects on both physical and mental well-being. Concurrently, adult children often have their own developmental needs including career development, family responsibility, and social networking. The Meaning Making model suggests that people are instinctively searching for meaning, in particular after encountering a life challenge and/or stressful condition. Research has shown that taking care of parents with dementia in Hong Kong is associated with “making meaning” on affirming self and enriching life. The proposed study furthers this knowledge by testing hypotheses based on a generation model for meaning making in dementia caregiving. The Baby Boomer Generation and Generation X have differences in their shared global meaning, which may have implications on their situational meaning making processes and ultimate adjustment. As members of the Baby Boomer Generation age and their children, members of Generation X, are becoming their caregivers, we propose a longitudinal survey of 760 adult child dementia caregivers. It aims to 1) investigate differences of meaning making in dementia caregiving between the Baby Boomer Generation and Generation X and 2) test the hypothesized relationship between meaning making in dementia caregiving, meaning made, and well-being indicators between and within the two generations. The longitudinal survey will inform the ongoing discussion amongst researchers, policymakers, and service providers on the need to crystallize different needs amongst generations and to generate dementia-related policies and services that are sensitive to the characteristics and needs of specific generations.
