The growth of the Internet, and specifically social networking sites (SNSs) like Facebook, create opportunities for individuals to share private and identifiable information with a closed or open community. Internet crime has been on the rise and research has shown that criminals are using individuals' personal information pulled from social networking sites (SNSs) to conduct varying levels of crimes. Hiring managers in assessment of candidacy for job placement are also viewing the personal information on SNSs. The present study served two purposes. First, it identified the frequency and types of personally identifiable information being disclosed by college students between the ages of 18 and 25. Second, the study included an examination of the differences between the student and university variables that may have influenced the frequency and types of personally identifiable information being disclosed on SNSs. To achieve these goals, an online survey was conducted among a sample of 8,800 students at two eastern U.S. institutions, one a private liberal arts college and the other a Pennsylvania state university. The investigator examined the external variables within the university such as a student's class membership, type of program enrolled, type of institution whether private or public, and involvement in extracurricular activities. The data indicated that there was a significant difference in the amount of information disclosed among the class membership and the type of institution attended. A primary limitation of the study was that the majority of students were female, White/Caucasian, with little representation of men and other racial backgrounds. Recommendations from the study included extending future research to other university types and in geographical locations, increasing the diversity of participants, and studying the longitudinal effects across generations to measure the implications of whether sharing behaviors are formed or nurtured.
