Effective self-presentation is challenging in the
contemporary computer-mediated communication
environment due to the abundance of other-provided
information. This study compared two approaches, one
that focuses on internal factors (the personality
approach) and the other environmental factors (the
network approach), explaining why individuals engage
in strategic self-presentation to manage other-provided
information on social network sites. Using an online
survey (N=322) of participants from the United States
and Singapore, results suggest that the two approaches
work differently in different contexts, depending on the
communication mode. Specifically, individuals who
stake self-esteem on physical appearance and have
diverse online networks are more strategic in their
maintenance of other-provided information. Practical
and theoretical implications about online selfpresentation
are provided.
