Definition of Violence

…...To understand violence, you

need to define violence

How would you define

domestic violence?

defining domestic violence
Defining Domestic Violence

domestic violencenoun: violence committed by one member of a family or household against another

The National Research Council defines violence as:

- behaviour by individuals that intentionally threaten, attempt, or inflict physical harm on others

who is affected by domestic violence
Who is Affected by Domestic Violence?

Children

Intimate Partners (IP)

Elders

data sources
Data Sources

You are planning to do a study of domestic violence using pre-existing data.

Where would you look?

Medical sources

State sources

Government surveys

surveillance in domestic violence
Surveillance in Domestic Violence
  • Hospital Admissions
  • Trauma Center Admissions
  • Emergency Department Admissions
  • State-based Reporting Systems
  • Government Surveys
    • National Criminal Victimization Survey
    • National Incidence Survey
    • Behavioral Risk Factor Survey
    • National Violence Against Women Survey

definition of health care events related to domestic violence
Definition of Health Care Events Related to Domestic Violence
  • Based on N-codes and E-codes
    • 995.80 to 995.85 adult physical abuse
    • 995.50 child abuse
    • E coding to distinguish domestic violence is relatively poor
    • E967.x
state based reporting
State Based Reporting
  • State-based Reporting
    • Child Protective Services
    • Uniform Crime Reports
    • National Incident-Based Reporting System (NIBRS)
    • Supplementary Homicide Report (SHR)
state based programs related to domestic violence
State-based Programs Related to Domestic Violence
  • Based on reporting to state agencies
    • most frequently for child maltreatment
    • definition of violence is not standard across the states
    • reporting is subject to knowledge of the issues to medical, educational, and legal personnel
government surveys
Government Surveys
  • Government Surveys
    • National Crime Victimization Survey (NCVS)
    • National Violence Against Women Survey (NVAW)
surveys related to domestic violence
Surveys Related to Domestic Violence
  • Self-report of violence based upon interviews
    • Aside from the NCVS, these surveys are not regularly collected
    • Definition of violence in surveys is not standard
    • There may be extensive under-reporting of violence
epidemiology of child abuse
Epidemiology of Child Abuse
  • Maltreatment
    • “behavior towards another person, which a) is outside the norms of conduct, and b) entails a substantial risk of causing physical or emotional harm”
          • Physical Abuse
          • Sexual Abuse
          • Emotional & Psychological Abuse
          • Neglect
types of maltreatment
Types of Maltreatment
  • Physical abuse: physical acts by a parent, guardian or caretaker that caused physical injury to the child.
  • Neglect (including medical neglect): the failure by the caretaker to provide needed, age-appropriate care (or provide for the health care) of the child.
  • Sexual abuse: the involvement of a child in incest, or sexual assault by a relative or caretaker, includes fondling and exposure to indecent acts.

Domestic Violence is wrought with ethical considerations unique to this field of research

key lecture points
Key Lecture Points
  • Surveillance for the frequency of domestic violence is not at the same level of development as for other unintentional injuries and for criminal violence
  • Several limitations, including differing definitions, poor coding, and under-reporting influence our knowledge of the frequency of domestic violence
  • Risk factor analysis in this area is just starting
