HBSC England
is committed to studying issues which are relevant to young people’s lives. The
study is tailored to cover important, up-to-date topics; for instance in the
next HBSC England questionnaire we intend to include questions on cyberbullying and sleep in accordance with societal changes and gaps in current
research. To coincide with the Association for Young People’s Health (AYPH) recent
report on self-harm1, this blog post explains why HBSC England will
be adding self-harm measures to the next survey round.
Self-harm is
a complex behaviour to define; essentially it describes the intentional harming
of one’s own body resulting in tissue damage2. It can involve many
behaviours including cutting, burning, scratching and swallowing toxic substances.
There is much debate surrounding the similarities between self-harm and
suicide; researchers are divided as to whether self-harm has suicidal intent or
not. Research demonstrating differences in the methods and frequency of those
self-harming with the intent to kill themselves and those without3 offers
support for defining self-harm as separate from suicidal ideation. The
motivations for suicidal self-harm have also been shown to differ to those
without suicidal intent; individuals with suicidal intent report self-harming
in order to make others better off whereas non-suicidal individuals report
self-harming as a way of expressing anger and to punish themselves4.
However, others believe distinguishing between the two behaviours is both
problematic and irrelevant. It is difficult to establish suicidal intent, and
there is a consistent link between self-harm and suicide5,6;
consequently researchers suggest self-harm should encompass all self-harming
behaviours irrespective of intent. Defining self-harm is also made increasingly
more difficult because a variety of terms are used to coin the behaviour,
including self-injury, self-poisoning, para-suicide and self-mutilation.
Research has
consistently shown that self-harm is a behaviour predominantly carried out by
adolescents7,8; it is also more common among females than males8.
The exact prevalence of self-harm is unknown; however it is estimated around
10% of adolescents report having self-harmed8. Self-harm is typically
carried out in private and kept hidden, so it is very difficult to measure
prevalence. Often prevalence rates have been based on hospital admissions for
self-harm, but this is not an effective measure as many self-harmers do not
require or seek hospital treatment. Consequently, the exact prevalence of
self-harm is unknown; and could feasibly be much higher than current
estimations.
The HBSC
England team will include questions on self-harm in their next survey; since we
want to both strengthen the evidence base around the prevalence of self-harm,
and also analyse the factors in a young person’s life that may correlate with
this behaviour. The aim is to not simply report the prevalence of self-harm
among young people but wishes to contribute to the current understanding of the
behaviour. Since the HBSC study examines young people’s lives in their broad
social context and includes questions about a wide variety of aspects of young
people’s lives including family, school, friends and the community; the breadth
of the study makes it possible to understand self-harm in more detail. We can
establish relationships between self-harm and other important factors in young
people’s lives; this will help to identify factors which put them at risk of
self-harming and factors which protect young people from self-harming. Recently
ChildLine reported a 68% increase in children seeking help for self-harm from
2011 – 20129. This increase may suggest that self-harm is on the
increase, which makes it even more important that self-harm continues to receive
research attention so we can begin to fully understand the behaviour. The HBSC
England team hopes the inclusion of self-harm measures in the HBSC study will
allow them to make a contribution to the knowledge and understanding of
self-harm among adolescents.
