The purpose of this research was to examine the equity theory in the relationships between the aged and their social supporters. The correlations between distress and loneliness in equitable as well as inequitable relationships were investigated by using equity theory. Respondents were sixty eight people aged 65 or older who lived at an old people's home. The results showed that the more benefited the relationship, the higher the Total Mood Index (TMI) scores were. Even if the aged perceived relationships as overbenefited, many of them reported less distress in spite of Walster's theory. The correlation between TMI and loneliness score was significant, and as TMI was high, loneliness score was low.
