See you, see me: Teenagers' self-disclosure and regret of posting on social network site

Self-disclosure is popular on social network site (SNS). However, teenagers' self-disclosure behavior and their regret of posting, a negative emotional experience, have been seldom studied. Using data from a nationally representative survey, this study tries to investigate teenagers' self-disclosure and regret of posting on SNS. We further examine how demographic variables, SNS use, different types of “friends”, trust, and privacy control behavior relate to self-disclosure and regret of posting. We find that though teenagers reveal moderately high level of personal information on SNS, they do not disclose all types of personal information equally. Results also show that male and older teens disclose more personal information. Frequent SNS use, large SNS network size, and having strangers in SNS friend list increase both self-disclosure and posting regret. Setting SNS profile private is related to lower level of self-disclosure. Implications for privacy design of SNS are discussed.
