Definition
  • A major disaster is a catastrophic,
    high-consequence event that a) overwhelms or
    threatens to overwhelm local and regional
    response capability, and b) is caused by natural
    phenomenon, massive infrastructure failure,
    industrial accident, or malevolent action.
    Indicators of capacity overload include the
    following
  • inability to adequately manage immediate rescue
    of survivors
  • significant backlog of victims waiting to get
    medical care or other essential support
  • inability to protect vital infrastructure or
    prevent significant property damage
  • signs of uncontrolled societal breakdown and
    psychological trauma

Background
  • In October 1948, a combination of hazardous
    chemical fumes in an industrial accident killed
    25 persons and sickened 43 of the residents in a
    small town in Pennsylvania. Military personnel
    observed that some residents not directly exposed
    exhibited the same physical symptoms as had
    victims who had been directly exposed.
  • The evidence prompted the military in January
    1950 to turn to social scientists and draw up a
    master plan for the study of psychological
    effects of disasters (one of the early major
    projects focused on a series of devastating
    tornadoes in March 1952).

Dr. Igor Khripunov, CITS/UGA

International Dimension
  • In September 2007, the World Health Organization
    released The Guidelines on Mental Health and
    Psychosocial Support in Emergency Settings
    clearly stating that protecting and promoting
    mental health and psychosocial well-being is the
    responsibility of all humanitarian agencies and
    people involved and not only the exclusive role
    of mental health professionals.

Dr. Igor Khripunov, CITS/UGA

Are We Prepared to Face Disasters?
  • 13 states do not have adequate plans to
    distribute vaccines, antidotes, and medical
    supplies from the National Strategic Stockpile
  • 12 states do not have a disease surveillance
    system that is compatible with the Centers for
    Disease Control and Preventions system
  • 7 states have not purchased their share of the
    federal stockpile of antivirals to use during a
    pandemic flu

Are We Prepared to Face Disasters?
  • Question In thinking about preparing yourself
    for a major disaster, which best represents your
    preparedness?

Lessons to Be Learned
  • Hurricane Katrina was the worst natural disaster
    in the U.S. in the past 75 years, affecting a
    land area the size of England, killing more than
    1,000 people, displacing 500,000 people, and
    causing 100 billion in property damage
  • More than 30 of the New Orleans residents met
    diagnostic criteria for post-traumatic stress
    disorder
  • Efficient provision of practical and logistical
    assistance in future disasters are important not
    only on humanitarian grounds, but also as a way
    to minimize the adverse mental effects of
    disasters leading to substantial human, economic
    and intellectual losses

17
Natural Events
  • Natural disasters have been associated with an
    intense but short-term impact and have a
    clearer end point than human-made disasters.
    People usually perceive them on the basis of
    their prior knowledge and after living through
    one event the next is unlikely to cause a serious
    psychological trauma. Global warming as a
    contributor to, and multiplier of, natural events
    has become a strong stressor.
  • Earthquakes occur with virtually no warning
    limiting the ability of disaster victims to make
    the psychological adjustment that can facilitate
    coping and lessening feelings of controllability
  • Tornadoes move on an unpredictable path,
    devastate houses and structures on their way and
    make survivor guilt an especially common coping
    challenge
  • Wildfires often lead to evacuations and loss of
    property. The sights, sounds and smells of
    wildfire often generate fear and anxiety

Dr. Igor Khripunov, CITS/UGA
18
Man-Made Unintentional Events
  • Man-made disasters often have an unclear end
    point, violate expectations of control, and
    result in distrust of authorities. The perception
    of threat does not always end with the
    termination of a human-made accident and there
    remain lingering chronic stress and fear.
  • Industrial and infrastructure accidents are
    expected to rise. The American Society of Civil
    Engineers assessed the condition and capacity of
    the U.S. public works with an overall grade of D
    (ASCEs 2005 Report Card for Americas
    Infrastructure). According to the same source,
    the Georgia Department of Transportation has
    projected a 74 billion shortfall in
    transportation infrastructure funding over the
    next 30 years.

Dr. Igor Khripunov, CITS/UGA
19
Man-Made Intentional (Malicious) Events
  • There is no single, universally accepted
    definition of terrorism. This term is usually
    used to describe violence that is political,
    social, religious, or ideological in nature and
    that is designed to influence an audience beyond
    the immediate target or victims of the attack
  • One widely quoted definition of terrorism is the
    one used by the FBI, which describes terrorism as
    the unlawful use of force and violence against
    persons or property to intimidate or coerce a
    government, the civilian population, or any
    segment thereof, in furtherance of political or
    social objectives. (U.S. FBI, 28 Code of Federal
    Regulations, Section O.85)

Dr. Igor Khripunov, CITS/UGA
20
Man-Made Intentional (Malicious) Events
  • The trauma of terrorism differs in several
    critical ways from traumas caused by disasters
    and accidents
  • The impact of terrorism is chronic. Unlike
    single-incident traumas, the threat of terrorism
    is not a contained experience with a clear-cut
    beginning and end. Terrorism can induce a
    generalized vigilance to the point of paranoia
    across a community.
  • Terrorism is a shared experience because attacks
    are most often directed against groups of people
    rather than individuals. The particular group of
    people attacked is often chosen based on their
    highly-visible membership in a larger racial,
    ethnic, or sociopolitical community.

Dr. Igor Khripunov, CITS/UGA
21
Known Risks and Unknown Risks
  • Prior knowledge and/or experience are important
    for people to assess unknown risks. Hence, known
    risks are associated with unknown risks for four
    different reasons
  • They are used to characterize the possible
    severity and consequences of the unknown risks
  • They are applied to show that similar risks have
    been tolerated and dealt with before
  • Associations serve to indicate that risky events
    and/or activities can also have benefits
  • Associations illustrate that previous risks have
    been resolved

What Does It Take for the Hazard/Disaster to
Become a Psychological Trauma-Causing Event
  • Experiences that involved serious risk of death
    (DSM-IV)
  • Death of a loved one (DSM-IV)
  • Personal victimization (DSM-IV)
  • Victimization of a loved one (DSM-IV)
  • Physical illness or injury
  • Extreme physical adversity
  • Major property loss
  • Income loss
  • Ongoing housing-related difficulties

Fear of Radiation Exposure
  • Radiation is colorless, odorless and tasteless
    (real or perceived?)
  • Effect is not immediate, leaving affected people
    in a stressful state of anticipation and dread
  • Potential impact of exposure on descendants can
    leave the affected people feeling guilty and
    depressed
  • Radiophobia can be defined as the irrational
    belief that any level of ionizing radiation is
    highly dangerous, if not immediately deadly.

Dr. Igor Khripunov, CITS/UGA
28
Risk Perception Professionals v. the Public
  • The objective is to achieve a common risk
    perception built on objective and transparent
    risk communication, which means an interactive
    process of exchange of information and opinion
    among individuals, groups and institutions. Risk
    and crisis communication is designed to achieve
    this objective.
  • Some risks are more accepted by the public than
    others
  • Voluntary risks are more readily accepted than
    imposed risks
  • Risks controlled by individuals or a community
    are treated with less fear and concern than those
    outside their control
  • Risks caused by human action are less tolerated
    than risks generated by nature
  • Risks that narrowly target an individual or a
    small group are more readily accepted than
    widely-spread and indiscriminate risks

Dr. Igor Khripunov, CITS/UGA
29
Risk Perception Professionals v. the Public
  • Perception of risk by the public, prior and
    mostly during the event, is based on such factors
    as
  • proximity to the ground zero or substance release
  • perceived magnitude of the consequences
  • ignorance about the nature of the hazard
  • the degree of physical harm that comes to oneself
    or fellow citizens
  • exposure to grotesque scenes of injury or death
  • suddenness of the event
  • distrust of the institution attempting to manage
    the hazard

Risk Perception Professionals v. the Public
Threat
Risk
Vulnerability
Consequences
Preparedness
  • Threat The probability that a specific area or
    group of people is targeted in a specific way
  • Vulnerability The probability that damages
    occur, in a specific event, on a specific target
  • Preparedness The probability that damages are
    prevented, in a specific event, on a specific
    target
  • Consequences The expected magnitude of
    consequences, given a specific event and specific
    target

Dr. Igor Khripunov, CITS/UGA
31
Effects of Large-Scale Disasters
  • The stress arising from the direct impact and the
    aftermath of a major event, particularly man-made
    malicious events can spawn serious physiological
    and psychological consequences. Traumatic life
    experience (cumulative stress) may exceed
    individuals coping ability, resulting in lasting
    changes in brain chemistry.
  • Physiological effects of stress
  • Increased risk of infections as a result of
    weakened immune system
  • Susceptibility to ulcers
  • Increased chances of blood clot formation and
    hypertension
  • Onset of diabetes and lupus
  • Chronic pain conditions such as arthritis and
    rheumatism
  • Nasal allergies such as asthma and skin allergies
    such as eczema
  • Risk factor for chronic fatigue syndrome (CFS)

Dr. Igor Khripunov, CITS/UGA
32
Psychological Reaction to Large-Scale Disasters
  • Sadness
  • Insomnia
  • Sense of vulnerability
  • Domestic or interpersonal violence
  • Loss of trust
  • Survival guilt
  • Fear for the future
  • Multiple Idiopathic Physical Symptoms (MIPS)
  • Vegetative Dystonia

Distress Responses
  • Changes in everyday patterns
  • Smoking
  • Drug abuse
  • Alcohol consumption
  • Use of prescribed medication

Behavior Changes
Psychiatric Illness
  • Post Traumatic Stress Disorder (PTSD)
  • Acute Stress Disorder (ASD)
  • Severe depression

Dr. Igor Khripunov, CITS/UGA
33
Post-Traumatic Stress Disorder
  • PTSD was first recognized as a diagnostic entity
    in 1980, when it was included in the DSM-III. The
    symptoms include psychological numbing, amnesia
    of certain aspects of the stressful event,
    inability to experience pleasure, isolation,
    reduced interest in activities, sleeplessness,
    agitation.
  • The prevalence of PTSD among
  • direct victims of disasters 30-40
  • rescue workers and first responders 10-20
  • general population 5-10
  • Long-term patterns
  • A latency period of delayed onset of some
    symptoms
  • Symptoms may wax and wane
  • Significant psychiatric symptomatology may remain
    for as long as 14 years
  • There is evidence of recurrence under the impact
    of similar events (lapsing-relapsing pattern)

Dr. Igor Khripunov, CITS/UGA
34
Vulnerable Groups
  • Several categories of the population are likely
    to experience more serious psychological effects
    that others. People belonging to these categories
    require specialized care in the pre- and
    post-event stages if they are to avoid long-term,
    often irreversible consequences. These categories
    include
  • Children
  • Pregnant women
  • Older adults
  • People with serious mental illnesses
  • Ethnic groups
  • First responders
  • Primary care providers
  • Social workers and volunteers
  • It would be a challenge to develop and implement
    any differentiated approach, because the
    population in American cities changes
    dramatically during a typical workday. U.S.
    Census data are readily available but the source
    can facilitate only the assessment of where the
    public resides and the demographics of
    neighborhoods.

Dr. Igor Khripunov, CITS/UGA
35
Vulnerable Groups Children
  • After the Armenian earthquake of 1988, 95 of
    children from a severely exposed city and 26 of
    children from a moderately exposed city had
    severe levels of PTSD 18 months after the event
  • Childrens inexperience, their incapacity to
    assess and respond appropriately to sudden
    dangers, and slow reaction times render them even
    more vulnerable than most other groups.
    Evacuation and separation from family are the
    most serious stressors for them.
  • In a 2006 study of the American Academy of
    Pediatrics, half the schools surveyed admitted
    that parents of their students do not know where
    their children would be evacuated in the event of
    a major disaster including terrorism

Dr. Igor Khripunov, CITS/UGA
36
Vulnerable Groups First Responders
  • After the 1983 bush fires in southeastern
    Australia, a 50 prevalence of PTSD was observed
    among firefighters during the first 2 years of
    follow-up
  • First responders and rescue workers are at a risk
    of adverse psychological outcomes, largely
    because of direct, extended exposure to the
    perils of a disaster. The terms compassion
    fatigue and vicarious traumatization describe
    the gradual psychological and physical decline
    that can occur when first responders are
    overloaded with traumatic events , causing their
    professional management and personal coping
    strategy to falter.
  • The same is true of members of the armed forces
    involved in post-event operations. The experience
    of treating civilian casualties, particularly
    children, can markedly increase the psychological
    impact on soldiers

Dr. Igor Khripunov, CITS/UGA
37
Vulnerable Groups Ethnic Minorities
  • A number of studies found that African-Americans
    were more likely that European Americans to
    develop PTSD despite their having fewer
    experiences of what is traditionally considered
    trauma. Latinos/Hispanics experience more PTSD
    than any other ethnic groups.
  • Their psychological response is not only
    individually-based, but also influenced by
    poverty and latent racism. Survivors who are
    illegal immigrants are likely to live under
    stress for fear of being deported and in the
    context of poverty, discrimination, and
    marginalization. Survival instinct in a hostile
    environment and exposure to chronic community
    violence influences how an individual responds
    to a specific, large-scale events.

Vulnerable Groups Athens-Clarke County
  • Population (2006) 111,300
  • Male 53,000
  • Female 58,300
  • School enrollment 50,500
  • Preschool 1,960
  • Kindergarten 1,500
  • Grades 1-12 3,700
  • Students 35,900
  • People with disabilities11,300
  • Non-U.S. citizens 8,100
  • Age groups 111,300 (total)
  • 20-60 years 66,400
  • 60 years 11,900
  • Note the share of the 60 age group across
    Georgia is expected to rise from 13.1 in 2000 to
    15.2 in 2010

Dr. Igor Khripunov, CITS/UGA
39
Vulnerable Groups Students
  • When surveyed in 2006 to identify the top ten
    impediments to academic performance, eight of
    them bore some relationship to potential health
    concerns
  • The number of students diagnosed with depression
    has been accelerating at an alarming rate. In
    2006, their number increased by 56 from 10 in
    2000 to 16 in 2005

Does the Public Have Enough Trust in the
Government?
(Report Commissioned by the National Center for
Disaster Preparedness at the Mailman School of
Public Health, National Survey July 2007)
Dr. Igor Khripunov, CITS/UGA
41
Getting the Public on Board
  • Risk and crisis communication can be defined as a
    two-way process of information exchange with the
    public that includes multiple types of
    information with multiple purposes
  • Gaining public support requires a realistic
    portrayal of risk that is accurate and draws a
    fine line between
  • Hyping the threat to spur people to action and
  • Trivializing the threat to provide them with
    reassurances
  • Partnership with the public provides a way for
    the public to translate risk awareness into
    action and can consist of a range of activities,
    including developing and practicing contingency
    plans, such as communication, evacuation and
    sheltering
  • As an important benefit, risk communication has
    the potential to build public trust and
    resilience in times of crisis.

Dr. Igor Khripunov, CITS/UGA
42
Resilience
  • Resilience is usually defined as the ability to
    handle disruptive changes, characterized as
    emergencies that can lead to or result in a
    crisis.
  • Resilience is an interactive product of belief,
    attitudes, approaches, behaviors, and physiology
    that helps people fare better during adversity.
  • The aim of building resilience among the public
    would be to reduce susceptibility to challenges
    by reducing the probability of the likely effects
    of a disaster, whatever its nature might be, and
    responding effectively to such effects as they do
    occur.

Dr. Igor Khripunov, CITS/UGA
43
Resilience
  • Effective and durable resilience in the face of
    large-scale disasters must be built on three
    tiers
  • organizational for reassuring the public that the
    federal government has been doing everything
    possible to support and assist the public, when
    needed, by protecting critical infrastructure,
    improving border control, providing state-of
    the-art first aid means, dispatching appropriate
    hardware and personnel to disaster-stricken
    areas, etc.)
  • social for integrating the public in local
    community planning, providing relevant
    information, and soliciting public input to make
    the arrangements as effective and palatable as
    possible. Social resilience makes society more
    coherent and cohesive but, above all, more
    confident in its objectives and values.

Dr. Igor Khripunov, CITS/UGA
44
Resilience
  • personal for building human qualities and traits
    enabling people to survive (resilient people bend
    rather than break during stressful conditions,
    and they return to their previous level of
    psychological and social functioning following
    misfortune)
  • strengthening close relationships
  • offering help and support to others
  • involvement in civic, faith-based, or other local
    groups to gain social support
  • developing an optimistic outlook
  • encouraging the belief that people can cope and
    are robust

Support Pyramid for Mental Health in Emergencies
46
Our Ultimate Objective
  • Mental health is defined as the successful
    performance of mental functions, resulting in
    productive activities, fulfilling relationships,
    the ability to adapt to change, and successfully
    coping with adversity
  • A mind is a terrible thing to waste
