Impact of QOL-Based Robot Counseling on Older Adults' QOL Improvement

This study aimed to develop a counseling robot to improve the quality of life (QOL) of older adults and verify its effectiveness. QOL is a comprehensive indicator that includes physical, mental, and social aspects, and gerontechnology aims to improve the autonomy and QOL of older adults. In recent years, utilizing robots to address the shortage of caregivers has been increasingly studied. We developed a counseling robot that estimates the QOL of older adults in real time, and generates appropriate and empathetic responses according to the estimated QOL. The results obtained from a one-week interaction experiment with a counseling robot targeted toward older adults indicated a significant improvement in the mental aspect of QOL, and the use of cognitive behavioral therapy and empathetic responses was inferred to facilitate self-disclosure and enhance the effectiveness of counseling. Additionally, advice based on the QOL estimation results contributed to organizing the thoughts of older adults and further improved their mental health. This study not only contributes to improving the QOL of older adults but also suggests that robots that understand and appropriately respond to individuals can facilitate continuous relationship building. This study may also serve as a guide for promoting the introduction of information and communication technology into welfare facilities.
