This study aims to understand parents’ role in adolescents’ visual information disclosure on Facebook as well as the mediating role of privacy concern and moderating role of Facebook network size. A total of 351 secondary school students who use Facebook participated in the study (49.6% boys; mean age M = 13.98, SD = 0.94). Results showed a significant mediating effect of privacy concern on the relationship between parental mediation and visual disclosure (b= −0.07, Boot SE = 0.02, 95% CI [−0.116, −0.028]). Furthermore, the effect of parental mediation on privacy concern was shown to be moderated by the level of network size (b = 0.15, SE = 0.05, t = 3.04, p < 0.01). Findings contribute to a better understanding of visual disclosure drivers, particularly of the underlying mechanisms of the protective effect of parental mediation. Practical suggestions for parents are discussed. Peran Orang Tua pada Berbagi Foto Personal di Kalangan Remaja: Model Mediasi Termoderasi yang Menggabungkan Perhatian Privasi dan Ukuran Jejaring Abstrak Publikasi foto-foto pribadi di situs jejaring sosial dapat berpotensi membahayakan pengguna remaja. Penelitian ini bertujuan untuk memahami peran orang tua pada publikasi informasi visual remaja di Facebook serta peran dari perhatian pada privasi dan keluasan jaringan sosial di Facebook sebagai mediator. Sebanyak 351 siswa sekolah menengah pengguna Facebook berpartisipasi dalam penelitian ini (49,6% anak laki-laki; usia rata-rata M = 13,98, SD = 0,94). Hasil analisis menunjukkan perhatian terhadap privasi merupakan mediator yang signifikan pada hubungan antara mediasi orang tua dan publikasi visual (b = −0,07, Boot SE = 0,02, 95% CI [−0,116, −0,028]). Selain itu, pengaruh mediasi orang tua pada perhatian privasi dimoderasi oleh besarnya jaringan sosial (b = 0,15, SE = 0,05, t = 3,04, p < 0,01). Hasil meningkatkan pemahaman kita untuk memahami alasan orang mempublikasikan informasi dirinya secara visual, terutama bagaimana mediasi orang tua berperan menjadi efek protektif. Saran praktis bagi orang tua dibahas lebih lanjut dalam penelitian ini.

Introduction The Internet has created a highly visual environment where users can easily see one another, using various media formats, most of which are still photographs and videos. Typical adolescents post many pictures and videos online using social networking services (SNSs) such as Facebook, Instagram, Snapchat, and blogs and even send visual media to unknown third-party websites (Chou, Liu, & Chou, 2019; Tsay-Vogel, Shanahan, & Signorielli, 2018). Disclosure of personal photographs could lead to potential harm to adolescent users, including identity theft, stalking, and cyberbullying, from third parties or online predators. Sharing photographs or videos with friends on SNSs is arguably perceived to be more compelling and personal than sharing textual
