Voice assistants' influence on loneliness in older adults: a systematic review.

This review aims to examine how the use of voice assistants influences loneliness in older adults. This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Databases such as CINAHL, APA PsycINFO, MEDLINE, PubMed, Web of Science, ScienceDirect, Scopus, SciELO, Google Scholar, and IEEE Xplore were used. We implemented search strategies in English to locate studies published between January 2010 and January 2023, including those examining the impact of voice assistant usage on loneliness in older adults. Descriptive information was examined, assessing its quality with the Mixed Methods Appraisal Tool. A total of 499 studies were yielded from the initial search, with 13 included in the final analysis. Positive outcomes in reducing loneliness were reported in 84.6% of these studies. There was a prevalence of quasi-experimental studies, alongside heterogeneous measurement instruments, scarce use of standardized tests, and small samples predominantly consisting of women. Commercial voice assistants were the most commonly utilized. Voice assistants show potential in mitigating feelings of loneliness in older adults. Adequate training and adaptation to specific needs seem essential to maximize their effectiveness. In particular, voice assistants available in the consumer market hold significant potential in this area. Further research is necessary to comprehend their impact, encompassing potential risks and ethical considerations.
