A Review of PTSD in Children

This review examines theoretical and empirical literature on children's reactions to three types of violence--child maltreatment, community violence, and interparental violence. In addition to describing internalizing and externalizing problems associated with exposure to violence, this review identifies ways that violence can disrupt typical developmental trajectories through psychobiological effects, post-traumatic stress disorder (PTSD), cognitive consequences, and peer problems. Methodological challenges in this literature include high rates of co-occurrence among types of violence exposure, co-occurrence of violence with other serious life adversities, heterogeneity in the frequency, severity, age of onset, and chronicity of exposure, and difficulties in making causal inferences. A developmental psychopathology perspective focuses attention on how violence may have different effects at different ages and may compromise children's abilities to face normal developmental challenges. Emphasis is placed on the variability of children's reactions to violence, on outcomes that go beyond diagnosable disorders, and on variables that mediate and moderate children's reactions to violence.

No randomized controlled studies have been conducted to date on the effectiveness of psychological interventions for children with symptoms of posttraumatic stress disorder (PTSD) that has resulted from personally witnessing or being personally exposed to violence. To evaluate the effectiveness of a collaboratively designed school-based intervention for reducing children's symptoms of PTSD and depression that has resulted from exposure to violence. A randomized controlled trial conducted during the 2001-2002 academic year. Sixth-grade students at 2 large middle schools in Los Angeles who reported exposure to violence and had clinical levels of symptoms of PTSD. Students were randomly assigned to a 10-session standardized cognitive-behavioral therapy (the Cognitive-Behavioral Intervention for Trauma in Schools) early intervention group (n = 61) or to a wait-list delayed intervention comparison group (n = 65) conducted by trained school mental health clinicians. Students were assessed before the intervention and 3 months after the intervention on measures assessing child-reported symptoms of PTSD (Child PTSD Symptom Scale; range, 0-51 points) and depression (Child Depression Inventory; range, 0-52 points), parent-reported psychosocial dysfunction (Pediatric Symptom Checklist; range, 0-70 points), and teacher-reported classroom problems using the Teacher-Child Rating Scale (acting out, shyness/anxiousness, and learning problems; range of subscales, 6-30 points). Compared with the wait-list delayed intervention group (no intervention), after 3 months of intervention students who were randomly assigned to the early intervention group had significantly lower scores on symptoms of PTSD (8.9 vs 15.5, adjusted mean difference, - 7.0; 95% confidence interval [CI], - 10.8 to - 3.2), depression (9.4 vs 12.7, adjusted mean difference, - 3.4; 95% CI, - 6.5 to - 0.4), and psychosocial dysfunction (12.5 vs 16.5, adjusted mean difference, - 6.4; 95% CI, -10.4 to -2.3). Adjusted mean differences between the 2 groups at 3 months did not show significant differences for teacher-reported classroom problems in acting out (-1.0; 95% CI, -2.5 to 0.5), shyness/anxiousness (0.1; 95% CI, -1.5 to 1.7), and learning (-1.1, 95% CI, -2.9 to 0.8). At 6 months, after both groups had received the intervention, the differences between the 2 groups were not significantly different for symptoms of PTSD and depression; showed similar ratings for psychosocial function; and teachers did not report significant differences in classroom behaviors. A standardized 10-session cognitive-behavioral group intervention can significantly decrease symptoms of PTSD and depression in students who are exposed to violence and can be effectively delivered on school campuses by trained school-based mental health clinicians.
