Latent difference score approach to longitudinal trauma research.

In this article, the authors introduce a latent difference score (LDS) approach to analyzing longitudinal data in trauma research. The LDS approach accounts for internal sources of change in an outcome variable, including the influence of prior status on subsequent levels of that variable and the tendency for individuals to experience natural change (e.g., a natural decrease in posttraumatic stress disorder [PTSD] symptoms over time). Under traditional model assumptions, the LDSs are maximally reliable and therefore less likely to introduce biases into model testing. The authors illustrate the method using a sample of children who experienced significant burns or other injuries to examine potential influences (i.e., age of child-adolescent at time of trauma and ongoing family strains) on PTSD symptom severity over time.

Incidence of and risk factors for acute stress disorder in children with injuries.

BACKGROUND: To assess the incidence of and risk factors for Acute Stress Disorder (ASD) in children with injuries. Numerous studies have documented the increased incidence of PTSD in those initially diagnosed with ASD. PTSD symptoms cause tremendous morbidity and may persist for many years in some children. METHODS: Children hospitalized with one or more injuries were interviewed and assessed with the following: Child Stress Disorders Checklist (CSDC), Family Strains Scale, Brief Symptom Inventory (BSI) and Facial Pain Scale. RESULTS: Participants included sixty-five children (ages 7-18 years). The mechanisms of injury varied (e.g. MVC, penetrating). The mean injury severity score was 8.9 +/- 7. The mean length of hospital stay was 4.6 +/- 4.6 days. Altogether, 18 (27.7%) of participants met DSM IV criteria for ASD during their acute hospital stay. Risk factors such as level of family stress, caregiver stress, child's experience of pain, and child's age were predictive of acute stress symptoms. CONCLUSION: We have identified four risk factors of ASD that have implications for the treatment, and possibly, preventative intervention for PTSD. Further investigation and greater understanding of risk factors for ASD in children with injuries may facilitate the design of acute interventions to prevent the long-term negative outcomes of traumatic events.

Pathways to PTSD, part I: Children with burns.

OBJECTIVE: The goal of this study was to develop a model of risk factors for posttraumatic stress disorder (PTSD) in a group of acutely burned children. METHOD: Seventy-two children between the ages of 7 and 17 who were admitted to the hospital for an acute burn were eligible for study. Members of families who consented completed the Child PTSD Reaction Index, the Multidimensional Anxiety Scale for Children, and other self-report measures of psychopathology and environmental stress both during the hospitalization and 3 months following the burn. A path analytic strategy was used to build a model of risk factors for PTSD. RESULTS: Two pathways to PTSD were discerned: 1) from the size of the burn and level of pain following the burn to the child's level of acute separation anxiety, and then to PTSD, and 2) from the size of the burn to the child's level of acute dissociation following the burn, and then to PTSD. Together these pathways accounted for almost 60% of the variance in PTSD symptoms and constituted a model with excellent fit indices. CONCLUSIONS: These findings support a model of complex etiology for childhood PTSD in which two independent pathways may be mediated by different biobehavioral systems.

Pathways to PTSD, part II: Sexually abused children.

OBJECTIVE: The goal of this research was to develop and test a prospective model of posttraumatic stress symptoms in sexually abused children that includes pretrauma, trauma, and disclosure-related pathways. METHOD: At time 1, several measures were used to assess pretrauma variables, trauma variables, and stress reactions upon disclosure for 156 sexually abused children ages 8 to 13 years. At the time 2 follow-up (7 to 36 months following the initial interview), the children were assessed for posttraumatic stress disorder (PTSD) symptoms. RESULTS: A path analysis involving a series of hierarchically nested ordinary least squares multiple regression analyses indicated three direct paths to PTSD symptoms: avoidant coping, anxiety/arousal, and dissociation, all measured during or immediately after disclosure of sexual abuse. Additionally, age and gender predicted avoidant coping, while life stress and age at abuse onset predicted symptoms of anxiety/arousal. Taken together, these pathways accounted for approximately 57% of the variance in PTSD symptoms. CONCLUSIONS: Symptoms measured at the time of disclosure constitute direct, independent pathways by which sexually abused children are likely to develop later PTSD symptoms. These findings speak to the importance of assessing children during the disclosure of abuse in order to identify those at greatest risk for later PTSD symptoms.

Review of child and adolescent refugee mental health.

OBJECTIVE: To review stressful experiences and stress reactions among child and adolescent refugees, as well as interventions and ethical considerations in research and clinical work, within the framework of the chronological experiences of child refugees; namely, the phases of preflight, flight, and resettlement. Highlighted are special refugee populations such as unaccompanied minors, asylum seekers, and former child soldiers. Pertinent medical findings are summarized. METHOD: The authors reviewed articles from 1990 to 2003 addressing the topics above. Literature was gathered from databases including PsycINFO, Medline, and SocioFile. Pertinent earlier papers and those from other disciplines cited in database-identified articles were also included. RESULTS: Child and adolescent refugees suffer from significant conflict-related exposures. Reactions to stress may be mediated by coping strategies, belief systems, and social relations. CONCLUSIONS: More research is needed on interventions, specifically on efficacy and cultural relevance. Interventions that have an impact on multiple ecological levels need further development and evaluation.

Testimonial psychotherapy for adolescent refugees: a case series.

Adolescent refugees are a traumatized, vulnerable group of arrivals to America who lack experience with or interest in psychiatric care. Testimonial psychotherapy's unique focus on transcribing personal, traumatic events for the altruistic purpose of education and advocacy make it an acceptable interaction by which to bridge the cultural gap that prevents young refugees from seeking psychiatric care. The theoretical basis for testimony is discussed. Testimonial psychotherapy has been used with adult refugees, but not with adolescents. This article describes the testimonial process with three Sudanese adolescents (the so-called 'Lost Boys'), which appeared feasible and safe. An efficacy study is underway.

Posttraumatic stress responses in children with life-threatening illnesses.

Posttraumatic stress symptoms have been reported in response to various serious medical illnesses in adults and children. Not surprisingly, posttraumatic stress is probably more common in response to acute, life-threatening, events that are related to the illness. Emerging data suggest that children often experience life-saving medical procedures as traumatic, which puts caretakers and medical personnel in the role of perpetrators for the children. Trauma symptoms are also reported as common and severe in caregivers. Both of these issues have been previously poorly understood and should be addressed in assessment and treatment. As with other traumatic events, developmental considerations, the nature and severity of the event itself, social supports, and premorbid exposure to negative life events are also important issues to consider in developing appropriate interventions. The importance of developing prevention and treatment for PTSD in medically ill children and adults includes increased morbidity and mortality (e.g., nonadherence to medications) and psychiatric sequelae and decreased quality of life. Obstacles to systematic study of a psychiatric intervention for this group include difficulties assessing multidrug regimens and cognitive treatment effects in this group. The relative stability of social supports and the potential use of preventive measures make this an attractive population for intervention. Clinicians and researchers are encouraged to work together to develop and use uniform screening and assessment methods that will help to identify cases and facilitate the multicenter trials that are vital to increasing knowledge in this patient population.

Self-destructive behavior in patients with dissociative disorders.

Highrates of self-injury have been reported in patients with dissociative disorders, yet no prior study has directly compared these patients with other psychiatric patients. The present study assesses self-destructive behavior in a group of inpatients who have dissociative disorders compared to those who report few dissociative symptoms. These patients more frequently engage in self-destructive behaviors, use more methods of self-injury, and begin to injure themselves at an earlier age then patients who do not dissociate. Results have important implications for understanding the relationship between dissociation, childhood trauma, and self-injury and for assessment and treatment of patients with dissociative disorders.
