However, this rise in the use of SNS by young people has been accompanied by increasing anxiety among parents and teachers. They are concerned about whether young users are prepared for the risks that come with using SNS, including privacy issues and unwelcome contact. A 2011 survey asked Australian parents, students, and teachers about their perceptions of the degree of risk when using SNS -- specifically, whether they felt it to be "safe," "a little risky," "very risky," or "risky but what everyone does." Figure 1 shows that over a quarter of students chose "safe," in other words, that they felt SNS use was without risk. In addition, 19.6% of students reported that, though they knew the dangers, they still used SNS because that is "what everyone does." In contrast with the students' responses, their parents and teachers were more cautious about the risk associated with SNS use, with teachers slightly more likely to see high risk. http://www.a-ema.com/img/center2015eng4a1.png Figure 1. Perceptions of SNS risk by parents, students, and teachers. http://www.a-ema.com/img/center2015eng4a2.png Figure 2. Perceptions of SNS risk by student year level. Interestingly, not all students had the same perception of risk. Figure 2 shows a comparison between students by year -- "Year 7" refers to first-year junior high school students and "Year 10" refers to first-year high school students. While the percentage of students who responded that SNS usage is "safe" was almost the same regardless of year, there was a drop by year in the percentage of students who chose "a little risky," and a rise in those who chose "risky but what everyone does." Furthermore, the study asked students about information security. It found that students from years 7 to 10 were increasingly cautious about privacy, becoming more careful by year about who could see their personal information online. Because Year 7 students, in addition to being the least cautious about information security, also tended to see SNS use as either "safe" or only "a little risky," they were believed to be at the greatest risk. The study then examined whether adults were discussing SNS risks with young people. However, the results here were not clear. While the study found that over 91% of parents and 68% of teachers said they discuss SNS issues with students, almost half of the students (46.1%) responded they do not talk with their parents, and almost three-quarters of the students (74.6%) responded that they do not talk with teachers. There are several possible explanations for this gap.
