Measurement Method
The calculation of this indicator is based on self-reported experience of bullying during the year preceding the survey. To improve validity, a description of bullying should be provided, followed by questions specific to different types of bullying, including in-person and cyber-bullying.
Numerator
Number of adolescents (10–19 years) who experienced bullying during the past 12 months
Denominator
Total number of adolescents (10–19 years)
Rationale
Bullying, both in-person and online, is highly prevalent and negatively impacts health, particularly mental health. Experiencing bullying has been linked to depression, anxiety and suicidality, with the potential for these effects to last into adulthood.

Comments
GAMA recommends this as a core indicator, essential for measuring the health of all adolescents globally. Bullying may occur in person or online (cyber-bullying) and is defined as unwanted, aggressive behaviour by a peer or a group of peers who are neither siblings nor in a romantic relationship with the victim. Bullying involves a repeated pattern of physical, psychological or social aggression likely to cause harm, and often takes place in schools and other settings where children gather, as well as online.
