The purpose of the current study was to examine the effects of Meridian acupressure in Joktaeyang Bangkwang Kyeong (one of 12 Meridian systems) on the physical health state, depression, and life satisfaction of Korean older adult women living alone. A quasi-experimental, pretest–posttest control group design was used. Participants included 76 (experimental: n = 38, control: n = 38) women 65 and older living alone in Seoul and Gyeonggido, South Korea. Meridian acupressure in Joktaeyang Bangkwang Kyeong was applied for 15 minutes twice per week, for a total of 8 weeks in the experimental group. Data showed there were significant differences in physical health state (t = −15.062, p < 0.001), depression (t = 3.241, p < 0.001), and life satisfaction (t = −17.141, p < 0.001) between the two groups. Health professionals must consider an array of methods, including Meridian acupressure in Joktaeyang Bangkwang Kyeong, for older adults.
