Social assistive robots and intelligent environments in psychological well-being in the elderly: a systematic review

Abstract

Recent advances have led to the development of assistive social robots and intelligent environments in assisted living facilities focused on prevention and promotion of health in the elderly and it is essential to explore the supporting evidence for these innovations. Consequently, we carried out a systematic review-PRISMA method-, examining 802 studies published between January 2019 and September 2024. We aimed to analyze the effectiveness of intervention with assistive social robots and assistive environments for daily living on various psychological variables in older people regardless of diagnosis of a mental disorder or were residing in an independent home or community residence, either alone or accompanied. After applying the inclusion and exclusion criteria, 12 studies were selected. The use of the technological devices was contextualized in different areas of intervention (social, promotion of autonomy, healthy habits, emotional, medical/psychological treatment or monitoring of health status, adherence to medication and cognitive area). A reduction in depressive and anxious symptoms was found, as well as an improvement in quality of life, social area, adherence to treatment, sleep, and autonomy. Most research proceeded from European countries and the US and consisted of experimental and quasi-experimental designs. The use of social care robots and smart environments are promising tools to promote psychological wellbeing and quality of life in the elderly.
