The purpose of this study is to examine the direct and indirect effects of Adult Day Health Care (ADHC) and family network on Quality of Life (QOL) for low-income older Korean immigrants in Los Angeles County, CA. A cross-sectional survey of low-income older Korean immigrants who use ADHC programs was conducted. Self-reported measures included sociocultural characteristics, acculturation, cognitive function, family network, utilization of ADHC, and QOL. The study found that for QOL, two variables had only direct effects: years in ADHC and acculturation. Family network was directly associated with QOL and indirectly associated with it through the variable "years in ADHC." Our findings indicate that a strong family network is positively associated with more years of attendance in ADHC, and with higher QOL scores. Thus, policy makers and practitioners should be aware of the positive association among social networks, attendance in ADHC, and higher QOL among low-income older Korean immigrants.
