Abstract: Psychologists, psychiatrists, doctors, and other associated 
professions, as well as the public from all over Europe have noticed the 
negative impact of the COVID-19 pandemic on mental health. In this 
regard, adolescents appear to be a highly vulnerable group, which is more 
affected than adults and children in many aspects. This study focuses on a 
specific and extremely maladaptive way of coping with mental stress and 
problems – deliberate self-harm. It offers an epidemiological study of the 
prevalence of self-harm among Slovak youths, its forms and related 
variables, carried out on a sample of 2,280 adolescents aged 11 – 19 
using the SHI questionnaire. The results reveal that within the overall 
prevalence of 45.2%, the most vulnerable group are girls from non-
traditional families who began to self-harm at an early age. The most 
frequent forms of self-harm among adolescents were torturing with self-
defeating thoughts, followed by both direct and indirect forms of physical 
self-harm. An analysis of the willingness to disclose self-harming 
behaviour shows that the need to raise awareness of this behaviour should 
be mostly oriented towards adolescents.

1. Introduction 

The COVID-19 pandemic has brought intense feelings of insecurity 
and a radical change in our way of life which has had an impact on the 
mental health of young people. Adolescents worry about their health as well 
as the health of those close to them, they feel isolated from their peer 
contacts that are important to them and the restrictions on their mobility 
have an immense effect, their daily routine is greatly disturbed, they have lost 
access to leisure activities... all of which limits the possibilities they have to 
meet their crucial needs. In more serious cases, they are the witnesses or 
victims of unfavourable domestic circumstances or violence and they lack 
access to psychological help. Yet, young people must live through these 
complications whilst also experiencing the challenging transition from 
childhood to adulthood (Casey et al., 2010), including the search for their 
own identity (Pfeifer & Berkman, 2018), sexual, emotional, and moral 
maturation (Bonnie & Backes, 2019), loosening of ties with the nuclear 
family and the formation of their first intimate relationships (Jager et al. 
2015), the choice of a future profession... At the same time, it is a period of 
emotional instability (Larson et al., 2002), of inner uncertainty and the 
absence of verified and functional coping strategies, which only makes the 
situation even more complicated. 

As is it difficult to cope with all of these developmental needs, with 
the radical changes in life and a lack of maturity in the areas that could 
potentially help to deal with these problems, adolescents tend to opt for 
maladaptive coping strategies. A very serious form is that of self-harm 
usually in order to reduce the impact or distract attention away from 
negative emotions, to punish oneself, and/or to reduce feelings of numbness 
or dissociation (Klonsky, 2007). Through such behaviour, individuals feel 
that they have control over their lives (Petermann & Nitkowski, 2015), 
which compensates for the absence of control over the current events and 
experiences. The danger of this type of behaviour not only lies in the health 
risks it poses (often associated with suicide), but also in its addictive nature 
(Victor et al., 2012); and in the fact that it does not resolve problems, quite 
the contrary – it worsens them. In order to improve the mental health care 
for adolescents and to effectively prevent such behaviour, it is crucial to be 
aware of the prevalence of self-harm and its associated circumstances.

2. Objectives 

The main aim of the study is to obtain the fundamental data relating 
to self-harming behaviour in adolescents. The secondary objectives include: 

• discovering the prevalence of self-harming behaviour in a sample 
of adolescents; 

• describing the forms of self-harming behaviour and their 
prevalence; 

• determining the average age when self-harm began and the average 
age of self-harming individuals; 

• revealing possible differences across genders, age groups and types 
of family backgrounds in the prevalence of self-harm; 

• describing the willingness to disclose self-harming behaviour 
among self-harming adolescents; 

• making essential recommendations for the most effective 
intervention strategies in the context of the current challenging situation. 

3. Method 

3.1. Participants and Procedure 

The study sample consisted of 2,280 Slovak adolescents (the WHO 
defines adolescents as the age group 11 – 19 – Aarø, 2007) attending 
primary or secondary schools. The anonymous collection of data included 
participants who (or their guardians) gave their informed consent for 
participation. The questionnaire was administered in a standard manner by 
trained administrators. Of the total number of 2,280 questionnaires, 61 
(0.27%) were excluded due to incorrect data. 2,219 participants were 
included in the research (63.1% female; mean age of all participants=15.34; 
st. dev.=1.58 years;), however, considering the sensitive nature of the topic 
of the research, the participants did not always respond to all questions. For 
this reason, each analysis was based on the available number of answers in 
the questionnaires.  

3.2. Measures and Statistical Analysis 

The data was collected using a modified Self-Harm Inventory (SHI) 
(Sansone & Sansone, 2010); the aim of the additional questions was to 
obtain basic demographic data as well as other data (family background, 
willingness to disclose the self-harm etc.). The SHI is a self-assessment 
questionnaire that consists of 20 items that reveal the presence of a relatively 
wide range of forms of self-harming behaviour. The items are preceded by 
the phrase, “Have you ever intentionally, deliberately to cause yourself

harm…” followed by several forms of self-harming behaviour (see Table 1). 
The participants were also asked to report how many times the behaviour 
has occurred as well as the frequency of the occurrence (0=never, 1=rarely, 
2=sometimes, 3=often). It is also possible to observe the intensity of 
prevalence and to measure, using the whole SHI questionnaire, the overall 
extent (level) of self-harming behaviour. Previous studies (see e.g. 
Démuthová & Doktorová, 2018) have confirmed the relatively high internal 
consistency of this method (Cronbach’s α=0.809). In order to classify a 
participant as a member of the group of self-harming individuals, it was 
necessary to admit to one form of self-harming behaviour with the 
frequency of 2 or 3 (sometimes or often). Or to admit to several forms of 
self-harming behaviour with a frequency of 1 or above. 

The data analysis was conducted using the IBM SPSS 22 statistical 
software. The statistical significance threshold (α) in each data analysis was 
set to 0.05. 

4. Results 

4.1. Prevalence of Self-Harm 

More than half of those in the research sample (56%) have 
intentionally harmed themselves at least once in their lives. After using the 
criterion for the classification of an individual as a member of the group of 
self-harming adolescents (recurrent self-harming behaviour), it may be stated 
that the prevalence of this phenomenon in the study sample is 45.2%.  

The prevalence of self-harming among those of female gender is 
significantly higher (Pearson Chi-Square=23.114; p=0.000); while the 
prevalence of self-harming reaches 39% among males, in the case of 
females, the prevalence reaches up to 49%. This tendency for a higher level 
of self-harming in those of female gender is also demonstrated in the 
analyses of the overall extent of self-harm for the group of self-harming 
individuals – using the SHI questionnaire, females reached an average score 
of 8.9, whereas men only reached 6.6. The application of Student’s t-test 
showed that the difference is statistically significant (t=4.512; sig.=0.000). 
An even more striking difference appeared in the analysis of a connection 
between family backgrounds and self-harm. While the prevalence of self-
harming individuals in traditional families reaches 41%, in non-traditional 
families, the prevalence increases to 57% (Pearson Chi-Square=42.64; 
p=0.000).

4.2. Forms of Self-Harm 

Table 1 clearly shows that all the forms of self-harm studied through 
the modified SHI questionnaire occurred in the research sample. 
Participants could list several forms of self-harming behaviour, which 
happens rather frequently – almost three quarters of the self-harming 
adolescents used more than one form. The most frequent form of self-harm 
was torturing with self-defeating thoughts, with a prevalence of 26.8%.

4.3. Age of Self-Harmers 

Student’s t-test did not reveal any age differences between the group 
of self-harmers and non-self-harmers (t=0.886; sig.=0.376). A further 
analysis showed that the prevalence of self-harming behaviour in the group 
of self-harmers does not relate to the actual age of the subject – a Pearson

test focused on the correlation between age and the SHI score did not show 
any relationship (correl. coefficient=0.002; sig.=0.948). On the other hand, it 
seems that such a relationship exists between the amount of self-harming 
behaviour (SHI score) and the age of the onset of self-harm (correl. 
coefficient=-0.121; sig.=0.005) – the earlier the individual starts to self-harm, 
the more massive the degree of self-harm in adolescence. 

4.4. Disclosure of Self-Harm 

An important point in the process of helping self-harming 
adolescents is the moment of disclosure. It is crucial to know to what extent 
they are willing to communicate their hardships and to whom they disclose 
this information. Of 1,002 self-harming adolescents only 553 (55.2%) were 
willing to answer the question of whether they had confided in someone and 
if they had who they disclosed the information to. The results reveal that 
most self-harming adolescents try to hide their behaviour from others – 
26.7% of the 553 adolescents indicated that they had not told anyone about 
their self-harming. Figure 1 presents the results for those (N=285) who have 
told someone about their self-harming behaviour.

Girls are statistically more prone to disclosure than boys (Chi-

Square=13.728; sig.=0.000); 55.9% of them (compared to 37.4% in boys) 
revealed their self-harming behaviour to someone. It appears that age is not 
linked to the willingness to disclose – there was no statistically significant 
difference in age found between the individuals who revealed their 
behaviour to someone and those who did not (t-value=1.712; sig.=0.088).

5. Discussion  

The analysis of the data shows that the prevalence of self-harming 
behaviour in the study sample is 45.2%. In contrast with the majority of 
countries, (4.7% in Belgium (Madge et al., 2008), 8% in Australia (Moran et 
al., 2012), 9.3% in Norway (Tormoen et al., 2013), 10% in England (Hawton 
et al., 2012) or 20.3% in the United States (Swahn et al., 2012) and 25.6% in 
Germany (Plener et al., 2009)) it is a rather high level of prevalence. Only a 
few studies (see e.g. Lundh et al., 2007) have reported similar figures. In 
addition to the situational and social specificities, this difference may be a 
consequence of inconsistent methodologies or different understandings of 
self-harm. In this regard, it may be advisable to promote some scientific 
activity towards the unification of the definition of this negative 
phenomenon. 

From the perspective of the forms of self-harm the most frequent 
form was “torturing with self-defeating thoughts”; this belongs among the 
mental forms of self-harming behaviour (see e.g. St Germain & Hooley, 
2012). Although it is indirect and hidden, its effect is just as devastating and 
strong; however, it targets the mental health of an individual, not their body. 
This finding leads us to reconsider the concept of self-harm, since there are 
certain tendencies to limit it to only the direct physical forms (e.g. the 
concept of non-suicidal self-injury, as proposed by DSM-5, 2013). The need 
for a broader understanding of self-harm is reaffirmed by the fact that 
various forms and types occurred in the study sample (mental, or direct and 
indirect physical forms). Attention must inevitably be paid to the high 
occurrence of attempted suicide (8.1%) among self-harmers. Considering the 
high risk of mortality and the rapidly growing prevalence of this behaviour 
(e.g. Clarke et al., (2019) report a 200% increase in suicides among girls aged 
10 – 14 years over the last 15 years), further research and prior intervention 
is imperative. 

From an age perspective, no significant differences were observed in 
terms of self-harm; this type of behaviour can be seen throughout the whole 
of adolescence. However, the age of onset of this behaviour plays an 
important role in its severity, it has a statistically significant correlation with 
the intensity of self-harm. This has also been reported by other studies (Jung 
et al., 2018). In this context, it would be appropriate to carry out further 
studies and analyses to attempt to define the cut point of high-risk age. The 
most vulnerable group is girls; although it is no longer true that self-harm is 
an almost exclusively feminine phenomenon, there still are statistics that 
indicate a higher prevalence amongst women (Laye-Gindhu & Schonert-



BRAIN. Broad Research in                                                                   August, 2020

Reichl, 2005). This trend may be explained from various perspectives – 
females are more likely to disclose their problems, whereas males are less 
likely to report self-harm and consider it a problem; further on, aggression 
may be more socially acceptable for males, therefore they have the 
opportunity to turn it outwardly instead of inwardly, which is more typical of 
females (Victor et al., 2018). In addition to being more prevalent amongst 
women, the risk of severe self-harm is increased if there is an unstable family 
background. This highlights the need for broader studies into this issue, for 
instance oriented towards the high-risk (and protective) factors of self-
harming behaviour.  

The key moment in helping self-harmers is their willingness to 
disclose their problems. No intervention can be realised without this step. 
The analysis of the data we have obtained clearly shows that self-harmers 
keep their behaviour secret. And even if they disclose it, it is most often only 
to their peers. Thus, not only is it necessary to inform the high-risk group 
(self-harmers) about the need for help and what is available, but also the 
whole adolescents population, since they are usually the decisive individuals 
in helping self-harmers to reach for help. The overall awareness for the need 
of mental health care and the help available should represent one of the 
priorities in every society, especially related to the highly vulnerable youth 
population. Particularly in the present times, when the COVID-19 pandemic 
has made it impossible to have face to face contact with others. Activities 
that aim to disseminate this type of information (e.g. through media – Saha 
et al. 2019) and make it more accessible should be significantly increased. 

6. Conclusions 

The issue of self-harming behaviour in adolescence is a highly 
relevant present-day phenomenon. The current situation in most countries 
has resulted in a deterioration of the state of mental health, and the 
population of adolescents is no exception. The options for the 
implementation of a more suitable approach are limited and help and 
intervention are difficult to access. Now more than ever it is crucial to 
intensively promote alternative forms of psychological intervention and to 
launch an informational campaign focusing on the high-risk section of the 
population, in order to make support available to as many adolescents as 
possible. Once the pandemic restrictions are lifted, professionals should be 
ready to address an increase in the need for psychological and psychiatric 
help and actively offer intervention in cooperation with teachers and parents

as well as with students. Research into the issue of self-harm should also 
continue, aiming, in particular, at the study of risk and protective factors.
