Feeling lonely when not socially isolated: Social isolation moderates the association between loneliness and daily social interaction

초록

Although it is widely acknowledged that people can feel lonely when not socially isolated, to our knowledge, no study has examined whether loneliness would be differently associated with daily social relations for people who are not socially isolated. The present study examined the role of social isolation (i.e., small social network size) in moderating the association between loneliness and characteristics of daily social interactionsinteraction type and qualitative characteristicsusing the 7-day social interaction diary data of 118 individuals. The moderating effect of social isolation on self-informant agreement in loneliness ratings was additionally examined, using three informant ratings of loneliness. Greater loneliness was more related to less frequency of strong tie interactions for people who are less socially isolated, while loneliness was more associated with greater self-focus during interactions for more socially isolated people. In addition, for those who are less socially isolated, the self-informant agreement in loneliness ratings was lower, suggesting that their loneliness might be underrecognized, even by those close to them. These results indicate that the relationships between loneliness and such social variables may operate differently depending upon the personal level of social isolation. In particular, our findings underscore the significant role of frequent interactions with close ties in alleviating the loneliness of people who are not socially isolated, suggesting that human social needs cannot be satisfied merely by a large number of social contacts.
