The primary purpose of study 1 was to show that social network use increases self-esteem primarily for those focused on strong ties while browsing the network. Specifically, we had people browse a social network before having them complete a measure of self-esteem. We expected those focused on strong ties to report higher levels of self-esteem after browsing a social network.We did not expect browsing a social network to affect the self-esteem of those focused on weak ties.
