The VTI Tragedy: Distinguishing Mental Illness from
Violence
Statement of Ken Duckworth, MD
NAMI Medical Director
The
National Alliance on Mental Illness (NAMI) extends its
sympathy to all the families who have lost loved ones in
the terrible tragedy at the Virginia Technology
Institute (VTI). We are an organization of individuals
and families whose lives have been affected by serious
mental illnesses.
Despite media reports, Cho Seung Hui, the shooter in the
tragedy may not actually have had a serious mental
illness relative to other diagnoses. But the possibility
opens the door for reflection on the nature of mental
illnesses—what they are and what they are not— with
regard to symptoms, treatment and risks of violence.
The
U.S. Surgeon General has reported that the likelihood of
violence by people with mental illness is low. In fact,
“the overall contribution of mental disorders to the
total level of violence in society is exceptionally
small.” More often, people living with mental illness
are the victims of violence.
Severe
mental illnesses are medical illnesses. They are
different from episodic conditions. They are different
from sociopathic disorders.
Acts
of violence are exceptional.
Treatment works, but only if a person gets it.
Questions must be answered about whether the mental
health care system responded appropriately in this case.
We know that Cho Seung Hui was referred to a mental
health facility for assessment. Did he receive the right
treatment and follow-up? If not, why not?
NAMI
offers below the federal government’s authoritative
language on perceptions of violence.
Mental Illness and Violence
Surgeon General’s Report on Mental Health (1999)
Are
people with mental disorders truly more violent?
Research supports some public concerns, but the overall
likelihood of violence is low.
The
greatest risk of violence is from those who have dual
diagnoses, i.e., individuals who have a mental disorder
as well as a substance abuse disorder. There is a small
elevation in risk of violence from individuals with
severe mental disorders (e.g., psychosis), especially if
they are noncompliant with their medication….Yet to put
this all in perspective, the overall contribution of
mental disorders to the total level of violence in
society is exceptionally small.
National Institute of Mental Health (2006)
A
study of adults with schizophrenia showed that symptoms
of losing contact with reality, such as delusions and
hallucinations, increased the odds of serious violence
nearly threefold. The odds were only about one-fourth as
high in patients with symptoms of reduced emotions and
behaviors, such as flat facial expression, social
withdrawal, and infrequent speaking.
Overall, the amount of violence committed by people with
schizophrenia is small, and only 1 percent of the U.S.
population has schizophrenia…By comparison, about 2
percent of the general population without psychiatric
disorder engages in any violent behavior in a one-year
period.
The
researchers found that the odds of violence also varied
with factors other than psychotic symptoms. For example,
serious violence was associated with depressive
symptoms, conduct problems in childhood, and having been
victimized, physically or sexually; minor violence was
associated with co-occurring substance abuse.
