What are the psychosocial effects of disasters?
Findings from an empirical review of the empirical literature
(a) specific psychological problems (disorders in the DSM-IV)
(b) nonspecific distress (i.e., subclinical elevation of symptoms associated with reactions to extreme stress),
(c) health problems and concerns (e.g., somatic complaints, substance abuse)

What are the psychosocial effects of disasters?
Findings from an empirical review of the empirical literature (continued)
(d) chronic problems in living (e.g., increased daily hassles secondary to the disaster)
(e) psychosocial resource loss (e.g., deterioration of personal hardiness and social support)
(f) problems specific to youth (e.g., separation anxiety, developmental regression, and externalizing behavior problems)

What are the psychosocial effects of disasters?
• Findings from Norris, Friedman, Watson, Byrne, Diaz, & Kaniasty, 2002:
• Levels of Impairment in studied samples:
• 51% (of 160) empirical studies reported moderate impairment among disaster survivors
• 39% reported severe to very severe impairment
• Suggests that a very substantial proportion of disaster survivors could benefit from psychosocial interventions
Comparable specification of effects on children is not evident in the literature

What are the significant gaps in knowledge about the harmful effects
of disasters on children’s psychosocial functioning?
17Northwest Center for
Public Health Practice
Gap 1: Descriptive Epidemiology
How are the psychosocial effects of disastersdistributed among the exposed children?
• Populations at risk (i.e., exposed) are inadequately defined.• Children are particularly overlooked.• Minority groups are underrepresented.
• Exposure is inconsistently defined.• Case definitions are inconsistently defined.• Reporting (data) sources are inconsistently selected.• Biased sampling methods (representativeness)
distort incidence and prevalence estimates (validity/reliability).
• The instruments of measurement are not standardized.
18Northwest Center for
Public Health Practice
Gap 1: Descriptive Epidemiology
How are the psychosocial effects of disastersdistributed among the exposed children?
• Change over time is seldom studied:• Lack of longitudinal investigations• Delayed onset latency is poorly studied.• Periodicity (e.g., phases, anniversaries) is poorly
studied.• “Natural” attenuation (i.e., tincture of time) goes
unmeasured.
19Northwest Center for
Public Health Practice
Challenges To Accurately Assessing Of The Psychosocial Effects Of
Disasters On Children
• Defining the populations at risk with sufficient breadth and specificity to ensure that children at all levels and types of exposure are properly screened.
• Employing unbiased sampling methods that yield results representative of the populations at risk.
20Northwest Center for
Public Health Practice
Challenges To Accurately Assessing Of The Psychosocial Effects Of
Disasters On Children• Adopting a standardized:
• set of instruments and protocols to be employed with consistency across studies.
• set of adequately differentiated (not just trauma) and specified case definitions to be employed with consistency across studies.
• protocol of data sources to be employed with consistency across studies.
• Overcoming the lack of baseline information.• Difficulty distinguishing disaster effects from
preexisting pathology.
21Northwest Center for
Public Health Practice
Challenges To Accurately Assessing Of The Psychosocial Effects Of
Disasters On Children
• Decreasing the time-lag between precipitating events and the initial point of measurement (time 1).• Advanced preparation.• Funding.• Permissions and access.
• Persuading and training researchers to adopt epidemiological standards.
• Replacing static snapshot studies with longitudinal designs that account for change over time.
22Northwest Center for
Public Health Practice
Which Factors Influence Those Effects?• Factors that increase risk (risk factors).
• Factors that reduce risk (protective factors).
• Factors that amplify or attenuate the translation of exposure into pathology (moderators)? • Affects the strength of the relationship.
• Factors that are necessary for the translation of exposure into pathology (mediators)?• Explains a mechanism of the relationship.
• These are the keys to resilience.
23Northwest Center for
Public Health Practice
Which Factors Influence Those Effects?• Vulnerability (Mediators and Moderators):
• What are the risk factors?• Female gender• Early or advanced age• Low SES• Pre-existing conditions • Degree of exposure• Unique event characteristics; e.g. terrorism &
media• What are the protective factors?
• Opposites of risk factors?• Training and experience?• Hardiness?• Self-efficacy?• Social support?
24Northwest Center for
Public Health Practice
Risk factors for more severe psychosocial impairment
• Conditions of mass violence or massive casualties• Severity and level of exposure• Severity and pervasiveness of the financial & social effects• Threat of or actual loss of life• Physical injuries• Pre-disaster psychosocial functioning• Post-disaster (secondary) stressors• Low Socioeconomic Status (SES)• Fewer social and economic resources (e.g., social support)• Higher risk among women, youth, disadvantaged “minority”
groups, and residents of less developed countries

What are the significant gaps in knowledge about variables that
influence the psychosocial effects of disasters on children?
26Northwest Center for
Public Health Practice
Gap 2: Differential Impact FactorsWhich variables influence the psychosocial effects
of disasters children?
• Risk and protective factors are poorly specified and inconsistently operationalized.• Personal attributes • Social/Cultural attributes• Environmental conditions and operators
• Stressors & buffers
27Northwest Center for
Public Health Practice
Gap 2: Differential Impact FactorsWhich variables influence the psychosocial effects
of disasters in children?
• Utility of risk and protective factors for screening is insufficiently examined• sensitivity• specificity
• Mediating and moderating relationships are insufficiently examined.
28Northwest Center for
Public Health Practice
Challenges To Assessing Variables That Influence The Psychosocial Effects Of
Disasters On Children• Hastily prepared research designs lead to:
• Over reliance on small samples and convenience samples.
• No power to examine complexity between variables (e.g., mediation and moderation)
• Over reliance on categorical variables.• Inability to examine complexity within variables
(e.g., threshold effects).• Over reliance on immutable variables; e.g. gender
• Poor utility for interventions. • Settling for descriptive results with poor
explanatory power.• Inability to study change over time.
29Northwest Center for
Public Health Practice
Challenges To Assessing Variables That Influence The Psychosocial Effects Of
Disasters On Children• Risk and protective factors need to be
conceptualized in ways that better inform prevention, intervention, and public policy.
• Examine relationships among risk and protective factors to distinguish between direct effects, mediators, and moderators.
• Increase reliance on theory-driven models that move from mere description to explanatory mechanisms.
• Examine the evolving influence of risk and protective factors over time.
• Employ more sophisticated modeling techniques to clarify complex interactions of predictors and outcomes.

Public Health Practice
What can be done to alter those effects?• Which interventions will proactively reduce risk
(prevention)?• Which interventions will reduce manifest
pathology?• Which factors amplify or attenuate the
translation of exposure into pathology (moderators)? • Affect the strength of the relationship.
• Which factors are necessary for the translation of exposure into pathology (mediators)?• Explain a mechanism of relationship.

Gap 3: Characteristics of Effective Interventions
Which characteristics influence the effectiveness of psychosocial interventions for children exposed
to disasters?• Inadequate scientific evidence to support use of
popularized interventions in the early post-disaster environment.
• Treatment samples don’t represent the population.
• Therapists in studies differ from counterparts in field settings.
• Tested interventions not employed in field settings
• Commonly used disaster interventions with children go untested under field conditions.
39Northwest Center for

Gap 3: Characteristics of Effective Interventions
Which characteristics influence the effectiveness of psychosocial interventions for children exposed
to disasters?
• Tested interventions are poorly disseminated and seldom adopted for field use, and field interventions are seldom tested.
• Modes of service delivery differ substantially between clinical settings and field settings.
• Barriers to care go unexamined

Challenges In Assessing the Effectiveness Of
Psychosocial Interventions for Disaster Exposed Children
• Competing priorities during the early phases of disasters.
• Political and social concerns about unintended consequences and implications.• Community resistance. • Limitations on access.
• Ethical concerns.• IRB approval barriers.• Funding barriers.
41Northwest Center for

ConclusionThe existing research literature on disaster mental
health, while rich and useful in many ways, isinadequate in the following ways:
1. Inadequate basic epidemiology.2. Unrepresentative samples. 3. Delay between precipitant and measurement (decay)4. Neglect of time as a variable. 5. Unsubstantiated extrapolation and generalization of
weak findings. 6. Inadequately systematic and precise examination of
variables and relationships.7. Untested effectiveness of interventions.

Impediments
• Lack of Prediction and Preparation• Lack of Funding and Human Resources
• Slow funding process• Lack of Access to Affected Populations
• Proximity• Competing Agendas & Priorities• Stigma and negative bias towards research• Ethical Objections
43Northwest Center for
Public Health Practice
Proposed Solutions• Prepare for predictable events and aspects.• Alter funding mechanisms to promote rapid
response protocols.• Integrate research designs into governmental
and non-governmental relief efforts.• Form geographically distributed research
networks to facilitate access and cut response times.
• Integrate research with other agendas & priorities.
• Target stigma, ignorance and negative biases towards research with public education campaigns.
• Promote policy reforms that raise the priority of children’s disaster mental health research.
44Northwest Center for
Public Health Practice
Proposed Solutions• Adopt a public health approach to studying the
psychosocial effects of disasters on children.• Adopt a developmental psychopathology
approach that examines the the risk and protective factors related to the psychosocial effects of disasters
• Promote the use of longitudinal designs that assess change over time.
• Adhere to scientific standards of evidence.• Develop and test approaches to interventions
that are congruent with local cultural values and expectations; e.g. community action research
• Confront pseudo-ethical objections: “We already know it works so…”
