Steven, age 6, lives in a foster home and attends an intensive day program for treatment of severe aggressive and violent episodes, for which he has been hospitalized several times. The boy has been separated from his biological mother for 2 years, and her parental rights have been terminated because of allegations of neglect and severe abuse.
Steven’s mother has a long history of substance abuse. Her boyfriend, who lived with her, abused Steven physically and sexually. He beat him, tortured him, and burned him. He once inserted a hot curling iron into the boy’s rectum, causing severe burns.
It is not unusual for psychiatrists to encounter children such as Steven who have experienced abuse, trauma, or a life-threatening event, but the psychological aftermath of these experiences has only recently been fully recognized. Diagnostic criteria continue to change with evidence that posttraumatic stress disorder (PTSD) manifests differently in children and adolescents than in adults. Now research is showing changes in brain physiology in children who have experienced maltreatment.
Based on our experience and recent evidence, we discuss important features of PTSD that are being recognized in children and adolescents and describe trends and acceptable practices in treating this chronic, debilitating illness.
Diagnostic criteria
PTSD is reported to occur in 1 to 14% of the general population of children1 and in 3 to 100% of children at risk (those exposed to violence, trauma, or abuse).2,3 As diagnostic criteria have changed over the years, so may have prevalence rates.
PTSD was recognized as a diagnostic entity in adults in DSM-III and in children and adolescents in DSM-III-R. PTSD in children has a somewhat different presentation and expression of symptoms than in adults. According to DSM-IV-TR diagnostic criteria:
- A child’s response to a stressful event may be expressed as disorganized or agitated behavior instead of intense fear, helplessness, or horror.
- Children re-experience and express the traumatic event or aspects of it through repetitive play.
- Children’s dreams may be frightening but without recognizable content, or they may change into generalized nightmares of monsters, of rescuing others, or of threats to self or others.
- Children also tend to have more psychosomatic complaints, such as headaches and stomachaches, than adults with PTSD.1
The person has been exposed to a traumatic event in which both of the following are present:
- The person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death or serious injury, or a threat to the physical integrity of self or others.
- The person’s response involved intense fear, helplessness, or horror. Note: Children may express this by disorganized or agitated behavior.
PROPOSED CHANGE FOR YOUNG CHILDREN
Children need not exhibit intense fear at the time of the trauma.

Age-related symptoms. Appropriate diagnostic criteria for childhood PTSD have been debated for some time, in part because of differences in children’s symptoms at different ages and developmental stages. Since DSM-IV was introduced in 1994, several researchers have recommended modifications to its diagnostic characterizations of childhood PTSD.
To accommodate the developmental stage of children younger than age 4, for example, Scheeringa et al suggested changes to DSM-IV criteria for PTSD.4,5 These changes (Boxes 1-5) are included in the American Academy of Child and Adolescent Psychiatry’s guidelines for assessing and treating PTSD6 and may be a valuable tool for the clinician treating young children.
Subsyndromal cases. Children whose symptoms fall below the diagnostic criteria for PTSD may demonstrate substantial functional impairment and distress, according to Carrion et al.7 In fact, these researchers found that children who fulfill the requirements for two of three symptom clusters—Cluster B, re-experiencing (Box 2); Cluster C, avoidance and numbing (Box 3); and Cluster D, hyperarousal (Box 4)—do not differ significantly from children who meet criteria for all three symptom clusters. Therefore—the researchers reported—the absence of this triad does not necessarily indicate a lack of posttraumatic stress in children but may stem from “developmental differences in symptom expression.”
Vulnerability. Traumatic experience contributes to PTSD development, and the “vulnerable, anxious child who is exposed to violence appears to be at greater risk,” according to Silva et al.8 After a regression analysis of 59 traumatized children, the research team concluded that PTSD risk is greatest when violence occurs within the family.
A review of 25 studies found that three factors appear to mediate the development of PTSD in children:
- the severity of the trauma exposure
- trauma related to parental distress
- temporal proximity to the traumatic event.9
