Cyberbullying — Recognising Signs Without Becoming Paranoid

The word 'cyberbullying' is used to describe an extremely wide range of online experiences, from sustained coordinated harassment to a single unkind comment. This matters because the evidence on prevalence, impact, and effective response applies specifically to the narrower, research-defined phenomenon — not to the broader category of 'anything unpleasant that happens online'.

The research definition

In the academic literature, cyberbullying is defined by three criteria: it involves aggressive or hostile behaviour that is (1) intentional, (2) repeated over time, and (3) involves a power imbalance between the person doing the bullying and the person targeted (Kowalski et al., 2014, p. 1074). All three elements are generally required for researchers to classify something as bullying, cyber or otherwise.

This definition excludes a great deal of what children and parents sometimes call cyberbullying:

• A single cruel or mocking comment, even a very hurtful one, does not meet the 'repeated' criterion.
• A conflict between two children of roughly equal social standing, even an unpleasant one, does not involve a power imbalance in the research sense.
• Being excluded from a group chat, while painful, is not necessarily bullying if it is not part of a sustained pattern of targeting.

None of this means these experiences are unimportant — a single hurtful comment can cause real distress, and online exclusion is a recognised form of social pain. But distinguishing them from sustained, targeted harassment matters because the appropriate response differs, and because conflating them inflates prevalence figures.

Prevalence: what the data shows

Estimates of cyberbullying prevalence vary widely depending on the definition used. Ofcom's 2024 research on children's online experiences found that around 14% of children aged 8–17 in the UK reported experiencing something they described as cyberbullying — though the proportion meeting the stricter research definition would be lower. Ditch the Label's 2023 Annual Bullying Survey reported that 13% of young people surveyed had been bullied online in the previous 12 months, with social media being the most frequently cited venue (Ditch the Label, 2023).

EU Kids Online's research across European countries found significant variation by country, with rates of repeated online harassment typically ranging from 5–15% of children surveyed, depending on methodology (EU Kids Online, 2020).

The takeaway is that cyberbullying at the research-defined level affects a meaningful minority of children — not a majority, and not every child who has an upsetting online experience. This context matters for how parents calibrate their concern.

Ordinary social conflict online

Much of what occurs between children online is ordinary social conflict — falling-outs, misunderstandings, status competition, and everyday unkindness — that has migrated from the playground and the school corridor to digital channels. These experiences are real and sometimes painful. They are also a normal part of social development, and children generally navigate them as they have always navigated offline conflict: with varying degrees of skill, distress, and adult support.

The parent's challenge is distinguishing between conflict that calls for comfort and guidance (by far the more common situation) and sustained targeted harassment that calls for a more structured response. The warning signs discussed later in this topic are oriented to that distinction.¹
