Chatbots to Support People with Dementia and Their Caregivers: A Systematic Review of Functions and Quality (Preprint)
BACKGROUND Over the past decade, there has been an increase in the use of information technologies to educate and support persons with dementia and their family caregivers. At the same time, chatbot technologies have become increasingly popular for use by the public and have been identified as having benefits for healthcare delivery. However, little remains known about how chatbot technologies may benefit persons with dementia and their caregivers. OBJECTIVE Our aim was to identify the types of currently available chatbots that are designed for use by persons with dementia and their caregivers and to assess their quality of features and content. METHODS Chatbots were identified through a systematic search of Google Play, the IOS store, Alexa skills, and the web. An evidence-based assessment tool was used to evaluate the features and content of the identified apps. The assessment was conducted through inter-rater agreement among four separate reviewers. RESULTS Of the 505 initial chatbots identified, six were included in the review. The chatbots assessed varied significantly in content and scope. While chatbots were generally found to be easy to use, there were noted limitations to their performance and programmed content for dialogue. CONCLUSIONS While chatbot technologies have become well-established and commonly used by the public, their development for persons with dementia and their caregivers is in its infancy. Given the successful use of chatbots for other healthcare settings and applications, there are opportunities for integrating this technology into dementia care. However, more evidence-based chatbots that have undergone end-user evaluation are needed to evaluate their potential for adequately educating and supporting these populations.
