The evidence base for cognitive behavioral therapy (CBT) to treat child emotional and behavioral symptoms following exposure to trauma in youth is compelling, but relatively few studies are available on preschool children and on moderators of treatment outcomes. This paper examines maternal and child characteristics as moderators of posttraumatic stress (PTS) treatment outcomes in preschool chi...

A wide range of modeling methods have been used to inform health policies. In this chapter, we describe the use of three models for understanding the complexities of post-traumatic stress disorder (PTSD), a major mental disorder. The models are: 1) a qualitative model describing the social and psychological complexities of PTSD treatment; 2) a system dynamics model of a population of PTSD patie...

We used structural equation modeling with 174 treatment-seeking military trauma survivors evaluated for posttraumatic stress disorder (PTSD) at a VA Medical Center PTSD clinic to examine relationships among lifetime mental health service use, PTSD symptom severity and medical problems (from self-report), as well as prospective (1-year) mental health and medical care use visit counts extracted f...

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) co-occur frequently, are highly correlated, and share three symptoms in common. In the present paper, the authors tested whether PTSD and MDD are similar or unique constructs by examining their symptoms using Rasch modeling. Data were used from the 766 trauma-exposed subjects in the National Comorbidity Survey-Replication ...

This study examined associations among disaster characteristics, relationship adjustment, and posttraumatic stress disorder (PTSD) symptomatology 9 months postdisaster in 205 women exposed to extensive flooding.

To evaluate the impact of posttraumatic stress disorder (PTSD) on health-related functioning, we assessed 800 U.S. Army soldiers before and after 1-year military deployments to Iraq. As part of the Neurocognition Deployment Health Study procedures, each soldier completed at both time points self-report indexes of PTSD symptom severity, health behaviors (smoking, alcohol use), and somatic health...
