'Trauma-Informed' Timeline

Origins, Policy Development, and Recent Changes (Pre-1900s – Present)

Pre-1900s – Early Psychological Foundations of Trauma Theory

  • 1895: Sigmund Freud & Josef Breuer publish Studies on Hysteria, introducing the idea that traumatic experiences, particularly in childhood, could cause psychological symptoms (later influencing psychoanalysis).
  • 1898: Pierre Janet, a French psychologist, introduces the concept of dissociation as a response to trauma, laying groundwork for modern PTSD understanding.

1900s–1960s – Trauma in War, Neuroscience, and Early PTSD Studies

  • 1914–1918 (World War I): Recognition of “shell shock” among soldiers, an early description of PTSD-like symptoms in war veterans.
  • 1940s–1950s (World War II & Korean War): Emergence of combat stress reaction, similar to PTSD.
  • 1952: The first edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-I) includes “gross stress reaction”, an early PTSD precursor, but it is later removed in DSM-II.
  • 1960s: Neuroscientists begin studying brain responses to stress and trauma, paving the way for later discoveries on how trauma affects memory and neurodevelopment.

1976 – Psychological Consequences of Stress, Vietnam Veterans, and the Women’s Rights Movement

  • The Vietnam War ends (1975), with large numbers of U.S. veterans returning home

    • Many veterans exhibit severe psychological distress, which at the time is labeled as post-Vietnam syndrome.
    • A significant proportion experience flashbacks, hypervigilance, nightmares, and emotional numbness—now recognized as PTSD symptoms.
    • The U.S. Department of Veterans Affairs (VA) expands research into combat-related trauma, influencing future trauma-informed policies.

  • 1976: Research on the psychological consequences of stress gains momentum

    • A landmark 1976 study links chronic stress exposure to long-term mental and physical health outcomes, paving the way for trauma-related research.
    • Early findings indicate that trauma responses extend beyond war veterans and are also seen in survivors of domestic violence, sexual assault, and childhood abuse.

  • Women’s Rights Movement & Recognition of Trauma from Domestic Violence & Sexual Assault

    • The Women’s Rights Movement of the 1970s leads to increased attention on domestic violence and rape trauma syndrome.
    • Psychologists and feminists advocate for recognizing domestic violence survivors as experiencing PTSD-like symptoms, challenging previous psychiatric models that dismissed women’s trauma.
    • Battered women’s shelters begin incorporating early trauma-informed practices, though the term TIC is not yet widely used.

1970s–1980s – PTSD, Neuroscience, and the Rise of Trauma Research

  • 1973: The term post-traumatic stress disorder (PTSD) is first introduced in relation to Vietnam War veterans.
  • 1978: Judith Herman begins research on complex PTSD (C-PTSD), recognizing that long-term trauma (e.g., childhood abuse, domestic violence) has different effects than single-event trauma.
  • 1980: PTSD is officially added to DSM-III—a landmark recognition of trauma’s psychological impact.
  • 1985: Bessel van der Kolk publishes early studies on how trauma is stored in the body, laying groundwork for The Body Keeps the Score (2014).
  • Late 1980s: Neuroscientists develop early brain imaging studies, showing that trauma affects brain structures (amygdala, hippocampus, prefrontal cortex).

1980 – PTSD Officially Recognized in DSM-III

  • 1980: Post-Traumatic Stress Disorder (PTSD) is formally added to the DSM-III

    • This marks a major shift in psychiatric recognition of trauma.
    • PTSD is classified as an anxiety disorder (later reclassified in DSM-5 as a trauma- and stressor-related disorder).
    • The diagnosis primarily arises from Vietnam veterans’ advocacy, but it also encompasses childhood trauma survivors, domestic violence victims, and sexual assault survivors.

  • Effects of PTSD Recognition on Policy:

    • VA hospitals expand PTSD treatment programs for veterans, setting a precedent for trauma-informed mental health services.
    • The U.S. criminal justice system begins acknowledging trauma in sentencing considerations, leading to early discussions on trauma-informed juvenile justice.

1990s – Groundbreaking Research & ACEs Study

  • 1994: Dr. Sandra Bloom develops The Sanctuary Model, one of the first organizational trauma-informed care models for mental health institutions.
  • 1995–1997: The CDC-Kaiser Permanente Adverse Childhood Experiences (ACEs) Study begins, demonstrating a direct link between childhood trauma and long-term physical/mental health outcomes.
  • 1998: ACEs study findings published (Felitti & Anda), revolutionizing trauma research and shaping future TIC policy.

2000s – Trauma-Informed Care Takes Shape

  • 2001 (9/11 Attacks): National focus on trauma leads to increased PTSD research.
  • 2004: The National Child Traumatic Stress Network (NCTSN) is established by Congress to improve childhood trauma treatment.
  • 2005: Hurricane Katrina response exposes gaps in trauma-informed disaster recovery.
  • 2008: SAMHSA begins incorporating trauma-informed language into behavioral health initiatives.

2010s – Federal Policy Shifts to Trauma-Informed Care

  • 2012: The Department of Justice (DOJ) integrates trauma-informed care into juvenile justice reform, advocating for rehabilitation over punishment.
  • 2013: Trauma-Informed Practice Guides released in Canada & UK, influencing global TIC policy.
  • 2014: SAMHSA publishes Concept of Trauma and Guidance for a Trauma-Informed Approach, establishing six core TIC principles:
    • Safety
    • Trustworthiness & Transparency
    • Peer Support
    • Collaboration & Mutuality
    • Empowerment, Voice & Choice
    • Cultural, Historical & Gender Issues
  • 2014: Treatment Improvement Protocol (TIP 57) published, formalizing TIC implementation in behavioral health.
  • 2016: CDC expands ACEs research, advocating for trauma-informed public health approaches.
  • 2017: Federal agencies, including HHS & DOE, increase funding for TIC in education, healthcare, and social services.

2018–2020 – Trauma-Informed Policy Becomes Mainstream

  • 2018: The SUPPORT for Patients and Communities Act mandates trauma-informed training in substance use treatment.
  • 2019: CDC publishes Preventing ACEs: Leveraging the Best Available Evidence, outlining trauma prevention strategies.
  • 2020: The Interagency Task Force on Trauma-Informed Care develops a National Strategy for TIC, emphasizing systemic trauma and racial equity.
