RISK FACTORS
"Risk"
is a concept used to predict the chance a behavior
will occur. Suicide risk factors are things that
increase the potential for a person's suicide or
suicidal behavior. Findings from recent research
have shown that most youth suicides are the result
of an interaction between biological, psychological,
socio-cultural, and family factors. A person's age,
gender, or ethnicity can increase the impact of
certain risk factors or combinations of risk factors
for them. A suicidal act can be seen as the result
of an interaction between background personal and
family factors, current emotional state and recent
significant life event which lead to an intolerable
mental anguish in the young person. The
"ingredients" required for completed or attempted
suicide vary from individual to individual.
Understanding risk factors can help counteract the
myth that suicide is a random act or results from
stress alone. There are, however, common risk
factors that we do know about:
Previous Attempts - Depression - Drug and Alcohol
Abuse - Conduct Disorder & Behavioral Factors
Disruptive and Unsupportive Family Background -
Relationship Conflicts - Social and Cultural Factors
Poor Coping Skills - Psychiatric Illnesses -
Availability of Means to Commit Suicide - Others
Previous Attempts
The most powerful predictor of completed youth
suicide is a past history of attempted suicide. As
the number of attempts increases, the risk of dying
from an attempt also increases. Additionally,
exposure to an attempted or completed suicide can be
a factor. This can be in a number of ways:
- Seeing
the person who completed suicide and being
involved in the aftermath.
- Having
talked with or seen the person on the day of the
suicide.
-
Belonging to the family of the deceased.
- Being a
close friend.
- Being
in the same class or group.
- Being a
friend of the family.
- The
attempted or completed suicide of a role model.
- Reading or
hearing about the death in the media.
Depression
Mood changes are common in teenagers but persistent
lowering or lability of mood may indicate the
presence of an underlying major depression.
Depressed youths, especially females, have a much
higher risk of suicide. The risk of suicide is
further increased if there is a family history of
depression and suicide. The symptoms of depression
vary a great deal, depending on the age of the
youth. The older they are the more likely they will
have adult type of depressive symptoms. Some common
symptoms include:
-
lowering of mood
- loss of
interest in daily activities
- social
withdrawal and isolation
- loss of
energy and motivation
- fatigue
- lack of
enjoyment in what the youth does
- sleep
disturbance (sleeping poorly or sleeping
excessively)
- change
of appetite (loss of appetite or eating
excessively)
- acting
out behaviour, including drug and alcohol abuse
- school
failure
- poor
self esteem with self reproach
- guilty
feeling
- a sense
of hopelessness and helplessness
- expression of
suicidal intent
Drug and
Alcohol Abuse
It is estimated that substance abuse occurs in 1/3
of youth suicides. Many youths who have difficulties
coping with their problems seek relief from drugs
and alcohol. Because they can "escape" from their
distresses temporarily with the use of drugs and
alcohol, non-coping youths tend to keep using these
substances. With increased use, the youth may become
emotionally and physically dependent on the drugs to
the point where he/she has to keep taking them to
avoid withdrawal symptoms. Unfortunately alcohol and
many drugs have depressant and disinhibiting
effects.
When drugs and alcohol are used in depressed youths,
they can become a lethal combination to precipitate
the suicide. Drugs, including the so called
"recreational drugs", can bring on psychotic
episodes with resultant hallucinations and delusions
which may then lead to suicide. Under the influence
of drug and alcohol, a youth may also develop the
clouding of his/her conscious state with resultant
loss of judgement and an increase in risk taking
behaviour. An accidental death may follow.
Conduct Disorder & Behavioral Factors
Youths with a history of conduct disorder have a
much higher risk of suicide because they tend to act
out their feelings in a destructive manner. This is
particularly true if they are isolated, angry,
aggressive, impulsive and they are abusing drugs and
alcohol. Many of these young people are in constant
crises. For example, they may be homeless and they
have frequent conflicts with the law because of
their anti-social activities. They are rejected by
others and they seek support from youths with
similar background. They take risks in what they do
and many of them are depressed individuals but
reluctant to admit to themselves or to others of
their true feelings or to ask for help. Other
behavioral factors may include:
- Writing
suicide notes and choosing suicide methods.
-
Variations in work performance or daily
lifestyle.
-
Behaviour indicating feelings of rejection,
humiliation, hopelessness or isolation.
- Impulsive
behaviour and other conduct disorders, including
rage, anger and hostility.
Disruptive and Unsupportive Family Background
Adolescence is a period of rapid growth both
physically, cognitively and emotionally. This is a
time of stress and confusion for many adolescents.
Their coping mechanisms may be stretched to the
absolute limit and in many instances beyond their
limits. Family support is particularly important in
the normal development of young people. When this
support is not available or inconsistent, or in some
instances when the family is actually "toxic" (e.g.
abusive, violent and in chronic discord) to the
young person, depression and anger may ensue with
dire consequences. Unrealistic, intrusive,
over-bearing and over-protective families can be
just as detrimental. Problems may also arise when
the needs of the youth are not met by the family due
to a poor "fit" between the parents and the
adolescent child. If considerable difficulties exits
in childhood, there is more risk that the young
person will attempt or complete suicide. Other
family risk factors include:
- Death
of a parent, caregiver or another family member.
-
Partnership dissolution and separation.
- New
family relationships
-
Geographic and social mobility.
-
Problems with friendships.
-
Inconsistent parenting.
-
Physical or psychiatric illness within the
family.
- Family
violence, including sexual abuse and other power
relationships.
-
Suicidal behaviour within the family
-
Poverty.
Relationship Conflicts
Many attempted suicides occur in the context of
relationship conflicts, e.g. following an argument
with parents, boy/girl friend or other significant
figure in the youth's life. The attempt can be seen
as an expression of anger and also a cry for help.
Fortunately, these conflicts are generally transient
in nature and they are frequently resolved. When
these conflicts are persistent and unresolved, the
youth concerned may be constantly stressed to the
point where he/she feels helpless, hopeless and
trapped. Death may be seen as a solution to the
problems.
Social and Cultural Factors
These do not explain suicide, but there is a direct
correlation with the increase in the rate of youth
suicide. They must, therefore, be considered as risk
factors, and include:
-
Increased rates of violence accompanied by
decreased levels of concern.
-
Marriage dissolution, remarriage and changes in
family structure.
-
Increased mobility, with disruption of
friendships and social networks.
-
Uncertainty, through changes in employment,
residence and access to education
- Change
roles of men and women.
- Lager
and less personal communities.
Poor
Coping Skills
Youths who have a past history of poor or
inappropriate coping skills are more at risk of
suicide. The demands on teenagers are great and
these demands may stress beyond the coping
capabilities of the already low functioning young
people. As a result they can develop a sense of
hopelessness and helplessness. They may then develop
major psychological or Behavioral symptoms or they
use self harm as an alternative way to cope.
Psychiatric Illnesses
Major psychiatric disorders such as schizophrenia,
anorexia nervosa and major depression carry with
them an increased risk of suicide. Symptoms of these
conditions may first present themselves in
adolescence. A young person with schizophrenia may
be directed to kill one self by a voice (auditory
hallucination), even though the young person may not
have any desire to die. Similarly a severely
depressed youth may feel (as part of his/her
depressive delusional belief) that one is better off
dead, to spare the suffering by his/her family
The Ready Availability of Lethal Means to Commit
Suicide
The higher rate of youth suicide in rural
communities is presumably related to the comparative
ease for young people to get hold of firearms.
History has indicated that the method of suicide is
directly related to the ease of access to the
specific lethal substance/object.
Others
There are other risk factors of suicide including:
- recent
bereavement
- chronic
physical illness
-
anniversary phenomenon (of past losses or major
life events)
- early
loss experiences
- school
failure
- chronic
unemployment
-
perfectionists and over-achievers who have high
-
expectations of themselves
Using the
risk factors described above, the profile of a youth
at risk of suicide can be painted as a severely
depressed and drug dependent young person who is
impulsive and has always struggled to cope. He/she
is poorly supported by a abusive or over-involved
family and he/she has poor resources or insight to
seek help. This picture of course does not fit the
description of all youths who commit suicide.
A "forgotten" group of youths are those who have
been chronically depressed and non-coping, but stay
in the background without others noticing their
distress. Their suicides may come as a surprise.
