This chapter discusses socio-cultural factors identified from a mixed method, qualitative data obtained through individual and focus group interviews, on welfare technology use among older adults, along with a comparison with quantitative data for corroboration. These are the results of a research project exploring differences in socio-cultural factors in two countries (Korea and the US), highlighting ways in which those differences affected welfare technology use among older adults living in each country. This is the first and only study with two groups on this topic conducted right before and during the COVID-19 pandemic. We conducted the research in three parts, using a sequential research method of two Focus Group Interviews (FGI) and one cross-sectional survey for comparison. The two qualitative studies identified socio-cultural factors in Korea and the US, and were followed by one quantitative study in both countries. Qualitative data analysis coding yielded seven primary themes. Of these, six themes and additional social-cultural characteristics were used to develop a survey. A total of 334 people, 65 and over, received and responded to the quantitative study, including 154 from Korea and 180 from the United States. Quantitative data results confirmed findings from the qualitative studies: self-determination vs. peer influence or social influence; importance of privacy, trust in government; motivation for health; and collectivism. However, other findings differed from the qualitative studies: benefit vs. cost; low- vs. high-context culture; and a culture of pursuing more indulgence. Future studies need to include attention to more recent advancements in technology.
