BACKGROUND Symptom-level variation in posttraumatic stress disorder (PTSD) has not yet been examined in the early post-deployment phase, but may be meaningful etiologically, prognostically, and clinically. METHODS Using latent class analysis (LCA), we examined PTSD symptom heterogeneity in a cohort of participants from the Marine Resiliency Study (MRS), a(More)
We examined the course of PTSD symptoms in a cohort of U.S. Marines (N = 867) recruited for the Marine Resiliency Study (MRS) from a single infantry battalion that deployed as a unit for 7 months to Afghanistan during the peak of conflict there. Data were collected via structured interviews and self-report questionnaires 1 month prior to deployment and(More)
BACKGROUND Lack of knowledge may contribute to a higher risk of nosocomial tuberculosis (TB) among Russian TB health care workers (HCWs). DESIGN Community-based participatory study. Russian TB HCWs at five TB facilities (n = 96) were surveyed to assess knowledge specific to TB and infection control. RESULTS Overall scores were low. Analysis of variance(More)
SETTING Five in-patient and out-patient tuberculosis (TB) care facilities in two regions of Russia. OBJECTIVE To identify barriers and motivators to the use of infection control measures among Russian TB health care workers. DESIGN In this qualitative study, a convenience sample of 96 health care workers (HCWs) was used to generate 15 homogeneous focus(More)
This article describes a study of the effects of caregiving on family members who assumed primary responsibility for managing the care of ventilator-assisted individuals in the home. Thirteen caregivers were interviewed and five variables associated with their role were assessed: caregiving tasks, burden of caregiving, impact of caregiving, mastery of the(More)
Large cohort studies suggest that most military personnel experience minimal posttraumatic stress disorder (PTSD) symptoms following warzone deployment, an outcome often labeled resilience. Very low symptom levels, however, may be a marker for low exposure, not resilience, which requires relatively high-magnitude or high-frequency stress exposure as a(More)
/ Synopsis In this chapter, we provide an overview of a widely used evidence-based treatment for PTSD called exposure therapy. We define terms, briefly depict the theory underlying the approach, describe what exposure therapy is, present the evidence for its efficacy, discuss treatment considerations, describe demographic variations, and discuss relevant(More)
