Posttraumatic Stress Disorder (PTSD) is associated with mild-to-moderate deficits in neurocognitive functioning. Single nucleotide polymorphisms (SNPs) in the brain-derived neurotrophic factor (BDNF) gene, namely, the Met allele, may also be associated with mild deficits in neurocognitive functioning. However, findings are inconsistent and may be sensitive to environmental epigenetic moderators such as psychopathology.

The current study analyzed data from European-American U.S. military veterans (n = 1,244) who participated in the 2011 National Health and Resilience in Veterans Study (NHRVS).

USC Aiken Psychology Theses

The current study explored the relationship between childhood trauma and deliberate rumination, as well as PTSD symptomology, psychological and physiological functioning. Participants consisted of 55 undergraduate students, ages 18-23; who completed measures about a specific traumatic event, psychological functioning, parental attachment, PTSD symptoms, deliberate rumination, childhood maltreatment, and a demographics questionnaire. Reported childhood trauma was a specifically identified traumatic life event, child maltreatment, or having a parent with a substance abuse or mental disorder. Following completion of measures, participants were asked to answer questions while heart rate, heart rate variability, and electrodermal activity were monitored. Results indicated there was relation …
