1 and 2 do not seem to suggest that cyberbullying is more harmful in this regard than other forms of bullying - and in fact only 3 seems to contrast these concepts at all.
> Sensitivity analyses suggested that cybervictimization only and both cyber- and face-to-face victimization were associated with a higher risk of suicidal ideation/attempt compared to face-to-face victimization only and no victimization; however, analyses were based on small n. In prospective analyses, cybervictimization was not associated with suicidal ideation/attempt 2 years later after accounting for baseline suicidal ideation/attempt and other confounders. In contrast, face-to-face victimization was associated with suicidal ideation/attempt 2 years later in the fully adjusted model, including cybervictimization.
In fact, reading 3, it looks like the highest prevalence of cyberbullying capped out at a whopping.... 16% of 15 year olds, with a sharp drop down to 7% just 2 years later.
I have to say, there's lots of things to worry about with kids going online. I just don't think bullying in particular is one of them.
