Disaster Mental Health Primer: Key Principles, Issues and

Questions 

 

NOTE: These materials represent highlights of the kinds of mental-health related information that might be beneficial in a disaster. 

Because of their brevity, they do not provide an exhaustive, formal review or compilation of the wealth of available knowledge on

disaster mental health. This is a starting point. There are companion pieces that provide similar information for city, county and 

state Public Health officials and as a general primer. Sources of additional information are listed at the end of this document. 

The Impact Pyramid (The victim count only represents the tip of the iceberg.) 

Individual victims 

Families and social networks 

Rescue workers, medical care providers, their families and social networks 

Vulnerable populations and impacted businesses 

Ordinary people and their communities 

Guiding Principles (It is helpful to keep these points in mind when preparing for or responding to a 

disaster.) 

• No one who experiences a disaster is untouched by it. 

• Most people pull together and function during and after a disaster, but their effectiveness is 

diminished. 

• Mental health concerns exist in most aspects of preparedness, response and recovery. 

• Disaster stress and grief reactions are “normal responses to an abnormal situation.” 

• Survivors respond to active, genuine interest and concern.

• Disaster mental health assistance is often more practical than psychological in nature (offering a 

phone, distributing coffee, listening, encouraging, reassuring, comforting). 

• Disaster relief assistance may be confusing to disaster survivors. They may experience frustration, 

anger, and feelings of helplessness related to Federal, State, and non-profit agencies’ disaster 

assistance programs. They may reject disaster assistance of all types.

Phases of a Disaster (General Principles. No precise, universal timeline exists. Responses vary by

disaster. These phases first were observed/described in natural disasters.)

• Warning of Threat: Ranges from no advance notice (suicide bomber) to weeks (hurricane)

• Impact: Actual onset of disaster Varies. BT has fuzzy beginning/end; bombing is precise 

• Rescue or Heroic: People watch out for, protect, even risk own safety to save strangers 

• Remedy or Honeymoon: People initially pitch in and collaborate for the collective good 

• Inventory: External resources begin to come online—people watch what goes where

• Disillusionment: Resource allocation often seen as too little too late, poorly distributed 

• Reconstruction and Recovery: People move beyond self interests and start to rebuild

Factors That Determine the Stressfulness of a Disaster (Individual responses are a function of 

the interplay of multiple factors.)

 Features of the Disaster 

Familiarity with the event Avoidability of the event 

Suddenness of its onset Intensity of its impact

Course and duration of the event Degree to which it can be controlled 

 Community or Societal Factors 

Previous level of community resources Community’s level of preparedness 

Extent and nature of damage done Community’s experience with such an event

Consequent social/political unrest Availability of resources to rebuild 

 Characteristics of the Individuals Involved 

Actual losses (and threat of loss) Previous experience with similar events 

Level of background stress in one’s life Physical or psychological closeness to event

Effectiveness of one’s coping mechanisms Nature and extent of available social support

Severity of Psychological Reaction After a Traumatic Event (Most people affected by a

traumatic event “recover” without external intervention.) 

Potential Risk Groups (Certain individuals/groups are more vulnerable than others.)

• Age groups (Infants, children and seniors) 

• Cultural and Ethnic Groups (immigrants, non-English speakers, undocumented aliens etc.) 

• Low-visibility groups (homeless, mobility-impaired, unemployed, mentally-challenged etc.) 

• People with Serious and Persistent Mental Illness 

• People in Group Facilities (hospitals, nursing homes, prisons)

• Human Service, Healthcare and Disaster Relief Workers 

Survivor’s Needs & Reactions (While people respond differently, there are common needs.) • A concern for basic survival 

• Grief over loss of loved ones and loss of valued/meaningful possessions 

• Fear and anxiety about personal safety and physical safety of loved ones 

• Sleep disturbances, often including nightmares and imagery from the disaster 

• Concerns about relocation and the related isolation or crowded living conditions

• A need to talk, often repeatedly, about events and feelings associated with the disaster 

• A need to feel one is a part of the community and its recovery efforts 

Reactions that Signal Possible Need for Mental Health Referral (Many responses to trauma

are expected, but some require extra attention and concern.)

• Disorientation (dazed, memory loss, unable to give date/time or recall recent events...) 

• Depression (pervasive feeling of hopelessness & despair, withdrawal from others...) 

• Anxiety (constantly on edge, restless, obsessive fear of another disaster...) 

• Mental Illness (hearing voices, seeing visions, delusional thinking...)

• Inability to care for self (not eating, bathing, changing clothing or handling daily life)

• Suicidal or homicidal thoughts or plans 

• Problematic use of alcohol or drugs

• Domestic violence, child abuse or elder abuse
