Fear conditioning studies in adults have found that posttraumatic stress disorder (PTSD) is associated with heightened fear responses and impaired discrimination. The objective of the current study was to examine the association between PTSD symptoms and fear conditioned responses in children from a highly traumatized urban population. Children between 8(More)
Angiotensin, which regulates blood pressure may also act within the brain to mediate stress and fear responses. Common antihypertensive medication classes of angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin receptor blockers (ARBs) have been associated with lower PTSD symptoms. Here we examine the rs4311 SNP in the ACE gene, previously(More)
Development of anxiety disorders is associated with neurobiological changes in areas that are a critical part of the fear neurocircuitry. Fear conditioning paradigms can offer insight into the mechanisms underlying the neurobiological ontogeny of anxiety. A small number of studies have focused on the effects of age and anxiety separately in school age(More)
Several mental illnesses, including anxiety, can manifest during development, with onsets in late childhood. Understanding the neurobiological underpinnings of risk for anxiety is of crucial importance for early prevention and intervention approaches. Translational neuroscience offers tools to investigate such mechanisms in human and animal models. The(More)
OBJECTIVE To investigate the relationship of illness uncertainty (IU) to global psychological distress (GPD) and posttraumatic stress symptomatology (PTSS) using a path analysis approach. METHODS Participants were 105 caregivers (MAge = 36.9 years, standard deviation [SD] = 8.7) of children (MAge = 8.6 years, SD = 5.0) with newly diagnosed cancer. A path(More)
OBJECTIVE Tympanostomy tube insertion is the most common pediatric surgery, but it typically requires general anesthesia. To facilitate in-office tube placement without general anesthesia, two complementary technologies have recently been developed comprising an iontophoresis system for delivering local anesthesia and an integrated tube delivery system. The(More)
Objective To examine the relationship of grit, an intrapersonal characteristic defined by perseverance and passion for long-term goals, to health care management skills and adolescent and young adult (AYA) health-related quality of life (HRQoL). Higher levels of grit were expected to relate to greater health care management skills and HRQoL, and skills were(More)
OBJECTIVE To examine predictors of psychological functioning in college students with chronic illnesses. PARTICIPANTS Participants (N = 1413) included 364 students with self-reported diagnoses of asthma or allergies, 148 students with other chronic illnesses (eg, epilepsy, type 1 diabetes), and 901 healthy students. Data were collected between November(More)
OBJECTIVE Examine caregiver demand and general parent distress as mediators in the parent illness uncertainty-child depressive symptom association in youth with juvenile rheumatic diseases.  METHODS  Children and adolescents completed the Child Depression Inventory; caregivers completed the Parent Perceptions of Uncertainty Scale, the Care for My Child(More)
Psychosocial distress is a salient construct experienced by families of children with newly diagnosed cancer, but little is known about parental appraisal of the child's illness and the subsequent impact this may have on child and parent functioning. The goal of the present study was to examine the interrelationships among multiple parent illness(More)
