A Typology of Social Networks and Its Relationship to Psychological Well-Being in Korean Adults.

The purposes of this study were to (a) develop an empirical typology of the social networks in Korean adults aged 18 years or older and (b) examine the relation of network types on depressive symptoms and satisfaction with life. Data for this study were drawn from the survey with 1,017 community-dwelling adults aged 18 years or older in South Korea representing three life stages: young adults, middle-aged adults, and older adults. Latent profile analysis was conducted based on eight social network-related variables: marital status, living arrangement, number of family confidants, number of friend confidants, frequency of contact with friends using phone or social media, frequency of participation in social groups, frequency of conversation with neighbors, and perceived closeness of family. The identified typologies were then regressed on depressive symptoms and satisfaction with life. A model with four network types was identified as being the most optimal, and the groups were labeled as: diverse-family, diverse-friend, solo-restricted, and coresident-restricted. Regression analyses showed that in comparison with the coresident-restricted group referent, diverse-friend and solo-restricted groups exhibited elevated levels of depressive symptoms; diverse-family and diverse-friend type had higher levels of satisfaction with life. Implications of the study findings were discussed in line with current research and intervention efforts.
