Effect of a Robotic Pet on Social and Physical Frailty in Community-Dwelling Older Adults: A Randomized Controlled Trial

The current randomized controlled trial investigated the effect of a robotic pet on social and physical frailty in community-dwelling older adults. The intervention group ( n = 107) received a robotic pet and the control group ( n = 113) received usual care following hospital discharge. Social and physical frailty were measured using the Questionnaire to Define Social Frailty Status and the FRAIL questionnaire. Cognitive function and depression were assessed using the Short Portable Mental Status Questionnaire and Geriatric Depression Scale, respectively. Continuous outcomes were compared between groups using t tests or Wilcoxon rank sum tests, as appropriate. Categorical outcomes were compared between groups using chi-square tests or Fisher's exact tests, as appropriate. Main findings showed the robotic pet positively impacted cognitive status in participants who reported they enjoyed engaging with their pet. This finding supported the theoretical premise of the current study that greater engagement with the robotic pet would yield greater improvement in study outcomes.
