Does social capital affect SNS usage? A look at the roles of subjective well-being and social identity

This study views social capital as a precursor of SNS (Social Network Service) use, which departs from the previous thoughts that considered social capital as the outcome of SNS activities. Drawing upon the theoretical premises regarding network-based social capital, this study examines the roles of subjective well-being and social identity in terms of their moderating as well as mediating influences on SNS use. This study sought to sub-categorize social capital and SNS use with a view to providing more refined theoretical and practical implications. The study's main objectives are three-fold: First, the study verifies whether social capital, categorized into bridging and bonding capital, influences one's SNS use as measured by qualitative use and quantitative use. Second, the study aims to confirm whether subjective well-being mediates between social capital and SNS use. Third, it examines whether social identity moderates the relationship between social capital and SNS use. The study result indicates that bridging capital only had a significant impact on qualitative use. However, subjective well-being did not mediate the relationship between social capital and SNS use. Finally, the cognitive identity caused significant difference in the effect of social capital on quantitative SNS use, whereas cognitive and affective identities caused significant differences in regards to the effects of bridging capital on qualitative SNS use.
