In a new study published in the journal Cyberpsychology, Behavior and Social Networking, University at Buffalo researcher Michael A. Stefanone, PhD, and colleagues found that females who base their self worth on their appearance tend to share more photos online and maintain larger networks on online social networking sites. He says the results suggest that females identify more strongly with their image and appearance, and use Facebook as a platform to compete for attention. The study, "Contingencies of Self-Worth and Social-Networking-Site Behavior," was co-authored by Derek Lackaff, PhD, University of Texas, Austin, and Devan Rosen, PhD, University of Hawaii, Manoa. It appeared in the journal's current issue. Its purpose was to investigate variables that explain specific online behavior on social network sites. Among other things, the team looked at the amount of time subjects spent managing profiles, the number of photos they shared, the size of their online networks and how promiscuous they were in terms of "friending" behavior.
