We have recently published an article in the International Journal of Public Health entitled
“Self-harm in adolescence: protective health assets in the family, school and community".
Self-harm can be defined as the act of deliberately causing
harm to oneself, and may include a number of behaviours such as cutting,
burning, hitting, scratching and self-poisoning1. The behaviour is
thought to be most common among teenagers2, and self-harming during
adolescence has been associated with an increased risk of mental health
problems in adulthood3.
Questions on self-harm were added to the HBSC England survey
for the first time in 2014, motivated by reports poor emotional wellbeing and
self-harm were on the increase among young people4,5. Furthermore,
a review conducted in 2013 by the Association for Young People’s Health (AYPH) identified
a lack of research on young people who self-harm but do not attend hospital
with their injuries6. We have blogged previously about the
motivation to include the topic of self-harm in the HBSC England survey, for
further details have a read of our blog post here.
Analysis of the 2014 HBSC England data identified around a
fifth (21.5%) of 15 year old respondents reported having self-harmed (data published
previously in articles by the Guardian and BBC).
Fifteen year old girls were nearly three times as likely as boys to report having
self-harmed; 31.9% of girls compared with 11.4% of boys. Figure 1 illustrates
how often young people were self-harming; the majority of those who self-harmed
reported self-harming around once a month.
Note: Figure 1 originates from Brooks et al. (2015)
Given that this is the first time self-harm has been added
to the HBSC England survey our data alone cannot tell us whether self-harm has
changed over time. However, comparing our data to a similar school based study
conducted in England during 2000/017 suggests self-harm rates may
have nearly tripled over the past decade. Questions on self-harm will be
included in the HBSC England survey during the next round, allowing us to
observe any changes between 2014 and 2018.
While it was important to gain new insight into prevalence
rates of self-harm, particularly for those young people who do not present at
hospital with their injuries, the HBSC study also allows us to examine the
relationship between self-harm and different elements of young people’s lives.
Our recent article sought to identify factors from the
family, school and community which may help protect young people against self-harming.
The study utilised data from a total of 1519 15 year olds who participated in
the 2014 HBSC England survey. Self-harm was measured via the question “Have you
ever deliberately hurt yourself in some way, such as cut or hit yourself on
purpose or taken an overdose?”
The analysis identified key elements which were associated
with self-harming including gender, family communication and a positive perception
of the school and neighbourhood environments. In line with existing research6,
the analysis identified girls were at a greater risk of self-harming compared
to boys. The paper highlights the important role parents may play in preventing
self-harm, as young people who found it difficult to talk to their mother and
father had a greater chance of reporting self-harm than those who described
family communication as easy.

findings the full paper can be found by clicking here. The International Journal of Public Health have also created a useful visual summary of this paper which you can access here.
