title: Characteristics of family caregivers with sleep dissatisfaction in Japan: identification using CHAID dendrograms.
abstract: The rapid increase in the population of the elderly has raised several social issues. The current study focused on sleep dissatisfaction in family caregivers to identify family caregivers with a heavy care burden. This study aimed to detect the characteristics of caregivers who are most likely to have sleep dissatisfaction. A chi-squared automatic interaction detection technique was used to analyze data collected from 92 research care managers who collected demographic and sleep dissatisfaction information from 280 caregivers and their care recipients. Caregivers whose care recipients were unstable and bedridden were most likely to have sleep dissatisfaction. When care recipients were not stable or non-bedridden, had severe dementia symptoms, and were physically independent, their caregivers were the second most likely to have sleep dissatisfaction. When care recipients were not stable or non-bedridden, had moderate dementia symptoms, and did not need help in transferring, their caregivers had the lowest risk of sleep dissatisfaction. Although many recent studies have found a high prevalence of insomnia among the elderly, describing the characteristics of caregivers who are most likely to have sleep dissatisfaction is a significant challenge. When care recipients are physically independent, the severity of the recipient's dementia symptoms relates to the caregiver's dissatisfaction with his/her sleep. In physically dependent care recipients, the severity of the recipient's dementia did not contribute to the caregiver's dissatisfaction with his/her sleep.
