The purpose of this study was to investigate the moderating effects of disturbance of adaptive functions
caused by SNS on the relationship between parental attachment, peer conformity and SNS peer bullying.
The participants comprised 611 students (7th, 8th and 9th grade) drawn from four middle schools in
Seoul, Gyeong-gi and Gangwon provinces. Data were collected through a survey. Statistical methods used
for data analysis were frequency, percentile, and moderated multiple regression. Analyses were conducted
using the SPSS 19.0. The major findings were as follows. First, adolescents' levels of parental attachment
and peer conformity had a significant effect on their SNS peer-bullying. Second, disturbance of adaptive
functions caused by SNS had a moderating effect on the relationship between peer conformity and SNS
peer-bullying. High levels of disturbance of adaptive functions caused by SNS tended to increase the effect
of peer conformity on SNS peer-bullying. However, in contrast, low levels of disturbance of adaptive
functions caused by SNS diminished the effect of peer conformity on SNS peer-bullying. The findings of
this study can be applied to SNS peer-bullying prevention education and intervention programs for middle
school students.
