Early childhood trauma generally refers to the traumatic experiences that occur to children aged 0-6. Because infants' and young children's reactions may be different from older children's, and because they may not be able to verbalize their reactions to threatening or dangerous events, many people assume that young age protects children from the impact of traumatic experiences. When young children experience or witness a traumatic event, sometimes adults say, "They're too young to understand, so it's probably better if we don't talk to them about it." However, young children are affected by traumatic events, even though they may not understand what happened.
A growing body of research has established that young children-even infants—may be affected by events that threaten their safety or the safety of their parents/caregivers, and their symptoms have been well documented. These traumas can be the result of intentional violence—such as child physical or sexual abuse, or domestic violence—or the result of natural disaster, accidents, or war. Young children also may experience traumatic stress in response to painful medical procedures or the sudden loss of a parent/caregiver.

Traumatic events have a profound sensory impact on young children. Their sense of safety may be shattered by frightening visual stimuli, loud noises, violent movements, and other sensations associated with an unpredictable frightening event. The frightening images tend to recur in the form of nightmares, new fears, and actions or play that reenact the event. Lacking an accurate understanding of the relationship between cause and effect, young children believe that their thoughts, wishes, and fears have the power to become real and can make things happen. Young children are less able to anticipate danger or to know how to keep themselves safe, and so are particularly vulnerable to the effects of exposure to trauma. A 2-year-old who witnesses a traumatic event like his mother being battered may interpret it quite differently from the way a 5-year-old or an 11-year-old would. Children may blame themselves or their parents for not preventing a frightening event or for not being able to change its outcome. These misconceptions of reality compound the negative impact of traumatic effects on children's development.
As with older children, young children experience both behavioral and physiological symptoms associated with trauma. Unlike older children, young children cannot express in words whether they feel afraid, overwhelmed, or helpless. However, their behaviors provide us with important clues about how they are affected.
Young children who experience trauma are at particular risk because their rapidly developing brains are very vulnerable. Early childhood trauma has been associated with reduced size of the brain cortex. This area is responsible for many complex functions including memory, attention, perceptual awareness, thinking, language, and consciousness. These changes may affect IQ and the ability to regulate emotions, and the child may become more fearful and may not feel as safe or as protected. Read more about the impact of trauma on brain development in Excessive Stress Disrupts the Architecture of the Developing Brain [2], a working paper from the Center on the Developing Child.
Young children depend exclusively on parents/caregivers for survival and protection—both physical and emotional. When trauma also impacts the parent/caregiver, the relationship between that person and the child may be strongly affected. Without the support of a trusted parent/caregiver to help them regulate their strong emotions, children may experience overwhelming stress, with little ability to effectively communicate what they feel or need. They often develop symptoms that parents/caregivers don't understand and may display uncharacteristic behaviors that adults may not know how to appropriately respond to.

Young children are exposed to traumatic stressors at rates similar to those of older children. In one study of children aged 2-5, more than half (52.5 percent) had experienced a severe stressor in their lifetime (Egger & Angold, 2004).
The most common traumatic stressors for young children include: accidents, physical trauma, abuse, neglect, and exposure to domestic and community violence.

Data from National Child Traumatic Stress Network (NCTSN) Sites
In 2002 the NCTSN Complex Trauma Task Force conducted a clinician survey on trauma exposure for children who were receiving assessment and/or intervention services. Among the findings, published in a white paper— Complex Trauma in Children and Adolescents [4](2003) (PDF)
[5]—was that 78 percent of children had experienced more than one trauma type and that the initial exposure on average occurred at age 5. Additional data from more than 10,000 cases of children receiving trauma-focused services from sites in the NCTSN reveal that in this cohort, one-fifth of children are aged 0-6. The traumas these children most often received services for were exposure to domestic violence, sexual abuse, neglect, and traumatic loss/bereavement (NCTSN, 2009).
Children suffering from traumatic stress symptoms generally have difficulty regulating their behaviors and emotions. They may be clingy and fearful of new situations, easily frightened, difficult to console, and/or aggressive and impulsive. They may also have difficulty sleeping, lose recently acquired developmental skills, and show regression in functioning and behavior.

The effects of traumatic experiences on young children are sobering, but not all children are affected in the same way, nor to the same degree. Children and families possess competencies, psychological resources, and resilience—often even in the face of significant trauma&1#151;that can protect them against long-term harm.
How Communities Can Help
Communities can do much to mobilize on behalf of children, and the larger society can make it a priority to make sure basic services are provided to children to help keep them safe.
How Parents/Caregivers Can Help
Research on resilience in children demonstrates that an essential protective factor for children is the reliable presence of a positive, caring, and protective parent/caregiver, who can help shield their children against adverse experiences. They can be a consistent resource for their children, encouraging them to talk about the experiences. And they can provide reassurance to their children that the adults in their life are working to keep them safe.

Due to the particular developmental risks associated with young children's traumatic experiences, it is essential that vulnerable children be identified as early as possible after the trauma. Many community resources—including health systems, Early Intervention programs, child welfare agencies, Head Start, child care programs, and early education systems—play an important role in identifying children, and in linking them and their families with services.
Some of these systems now try to address possible traumatic experiences by including questions about specific traumas into their intake and/or assessment protocols. For example, both Head Start and Early Intervention intake protocols include questions about domestic violence in families. Other protocols may include targeted questions about accidents, loss of family members, and/or significant medical history.

For Mental Health Professionals
Behavioral Health Assessment
Assessment of trauma in young children must focus on the presenting problem in the context of the child's overall development. This information can be gathered though interviews with the parents/significant caregivers in the child's life, observation of the parent/caregiver-child interaction, and standardized assessment tools. Clinical assessment should include review of the specifics of the traumatic experience(s) including:
Instruments for Assessing Traumatic Stress In Young Children Below is a list of some of the standardized instruments used within the NCTSN to assess traumatic stress in young children.
Instruments for Assessing Parenting Stress and Strengths
|
When conducting an assessment of a young child, it is also important to assess developmental delays (e.g., gross/fine motor, speech/language, sensory processing), which may indicate that the child could benefit from evaluation and/or services from another professional (e.g., occupational therapist, speech/language therapist, physical therapist). It is often helpful to consult and/or to work collaboratively with these professionals.
For Medical Professionals
Screening/Assessment in Health Settings
Most young children are seen at regular intervals by providers in the pediatric health care system, enabling repeated opportunities for identifying early childhood trauma.
Medical providers can also play an important role in diminishing risks and in maximizing protective factors associated with young children's exposure to trauma. They can supply information to prevent accidents and can incorporate questions about stressful and traumatic experiences into their interviews with families.

For Faith-Based, Community, and Mentoring Organizations
Community and faith-based organizations have in-depth knowledge of the resources and challenges in their communities. They play a vital role in linking families to resources that help stabilize and support them in the aftermath of trauma events. Advocating for families and increasing access to care can help families begin their recovery process.
Resources for Community Organizations
When young children experience a traumatic stressor, their first response is usually to look for reassurance from the adults who care for them. The most important adults in a young child's life are his/her caregivers and relatives. These adults can help reestablish security and stability for children who have experienced trauma by:

When to Seek Help for Your Child
For many young children who have been affected by a traumatic experience, the most effective help is the reassurance and comfort provided by parents and trusted caregivers. However, if the trauma is severe or chronic, if it affects those close to the child, and/or if the child continues to be upset or have symptoms after a month or so has elapsed, it is advisable to seek help for the child.
Parents/caregivers may wish to consult their pediatrician, their child's teacher, and/or their childcare provider for suggestions of professionals who specialize in early childhood mental health. Because of the young age of the child and the importance of the parents/caregivers in the child's life, treatment for the child should actively include those adults. See the section below for a summary of treatments designed especially for young children.

As recognition has grown about the prevalence and impact of trauma on young children, more age-appropriate treatment approaches have been developed and tested for this population. These interventions share many of the same core components. For example, they are generally relationship-based, and focus on healing and supporting the child-parent relationship. For an overview of these components, click here. [35]
Listed below are treatments that have been developed and evaluated for young children, each of which has significant support for efficacy. Many of these treatments are featured in the Network's listing of Empirically Supported Treatments and Promising Practices [36].
Alternatives for Families: A Cognitive Behavioral Therapy (AF-CBT) for Preschoolers
AF-CBT treatment is designed to help physically abused children and their offending parents by addressing underlying contributors to maltreatment including changing parental hostility, anger, maladaptive coercive family interactions, negative perceptions of children, and harsh parenting. |
Abused children are helped to view abuse as wrong and illegal; and are taught emotional comprehension, expression, and regulation as well as social skills. Parents learn proper emotion regulation skills, how to avoid potentially abusive situations, and healthy child management and disciplinary techniques. Dyadic work gives families an opportunity to measure progress, to help identify and clarify family miscommunication, and to establish a family no-violence agreement (Chalk & King, 1998; Kolko & Swenson, 2002).
NCTSN resource
Attachment, Self-Regulation and Competency (ARC)
ARC is a framework for intervention with youth and families who have experienced multiple and/or prolonged traumatic stress. ARC identifies three core domains that impact traumatized youth and that are relevant to future resiliency. ARC provides a theoretical framework, core principles of intervention, and a guiding structure for providers working with these children and their parents/caregivers, while recognizing that a one-size model does not fit all. |
Within the three core domains, ten building blocks of trauma-informed treatment and service are identified. For each principle, the ARC manual provides key concepts and guiding theoretical structure, educational information for providers and parents/caregivers, tools for clinicians, and developmental issues to consider. ARC is designed for youth from early childhood to adolescence and their parents/caregivers or caregiving systems.

Child-Parent Psychotherapy(CPP)
CPP integrates psychodynamic, attachment, trauma, cognitive-behavioral, and social-learning theories into a dyadic treatment approach designed to restore both the child-parent relationship and the child’s mental health and developmental progression that have been damaged by the experience of family violence. Child-parent interactions are the focus of the intervention. |
The goals are to address issues of safety, improve affect regulation, improve the child-parent relationship, normalize trauma-related response, allow the parent and child to jointly construct a trauma narrative, and return the child to a normal developmental trajectory. The intervention runs for fifty weeks and can be conducted in the office or in the home.
NCTSN resource:
Parent-Child Interaction Therapy(PCIT)
PCIT is a parent training intervention that teaches parents/caregivers targeted behavior management techniques as they play with their child. PCIT focuses on improving the parent/caregiver-child relationship and on increasing children’s positive behaviors. It has been adapted for children who have experienced trauma. |
Parents/caregivers are coached live by the therapist while engaging in specific play therapy and discipline skills with their child. PCIT is a short-term, mastery-based treatment that typically runs for sixteen to twenty weeks, based on the needs of the family.
NCTSN resource
Preschool PTSD Intervention
The Preschool PTSD Intervention is a protocol-specific cognitive-behavioral treatment that is combined with parent/caregiver involvement in every session. |
Treatment is for twelve weeks, and it can be focused on PTSD symptoms from any type of trauma. The cognitive-behavioral components include relaxation training, graded systematic exposure, and homework. The protocol also encourages coverage of parental and parent-child relational issues. The manual for this intervention, the Preschool PTSD Treatment Manual, was developed by Michael Scheeringa, MD, Judith Cohen, MD, and Lisa Amaya-Jackson, MD, and is available free by contacting Dr. Scheeringa at mscheer@tulane.edu [42].
Trauma Focused Cognitive Behavioral Therapy (TF-CBT)
Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) uses cognitive-behavioral theory and principles, and was developed by Judith Cohen, MD, Anthony Mannarino, PhD , and Esther Deblinger, PhD. TF-CBT was originally designed for children with posttraumatic symptoms as a result of sexual abuse. |
Treatment generally consists of twelve treatment sessions. Maltreated children and their nonabusing family members learn stress-management skills; and they practice these techniques during graduated exposure to abuse-constructed trauma. The parents/caregivers learn how to address their own emotional reactions. Several joint parent/caregiver-child sessions are also included to enhance family communication about sexual abuse and other issues. Children who participate in TF-CBT show significant improvement in their fear reactions, depressive symptoms, inappropriate sexualized behaviors, and self-worth.
