Social networking sites have become an increasingly popular tool to manage relationships for college students; however, the content posted on these sites can be problematic for relationships (Palevitz & Samp, 2008). This thesis examines the potentially relationally-deleterious effects of social networking sites, with a focus on how judgments about dependence power in a romantic relationship influences how an individual responds to a partners posted information, both generally and when such information suggests that a relational transgression may have occurred. An 81-item survey that included measures of dependence, items to assess respondents general monitoring and communication about a partners Facebook behavior, and transgression-specific items related to how individuals perceive and would communicate about relational transgressions revealed on Facebook was utilized for in this study. While analyses revealed no direct support for the influence of dependence power the hypothesized associations, several main effects for the commitment and SNS use were observed.
