Description
Military veterans have a significantly higher incidence of mild traumatic brain injury (mTBI), depression, and Post-traumatic stress disorder (PTSD) compared to civilians. Military veterans also represent a rapidly growing subgroup of college students, due in part to the robust and financially incentivizing educational benefits under the Post-9/11 GI Bill. The overlapping cognitively impacting symptoms of service-related conditions combined with the underreporting of mTBI and psychiatric-related conditions, make accurate assessment of cognitive performance in military veterans challenging. Recent research findings provide conflicting information on cognitive performance patterns in military veterans. The purpose of this study was to determine whether service-related conditions and self-assessments predict performance on complex working memory and executive function tasks for military veteran college students. Sixty-one military veteran college students attending classes at Arizona State University campuses completed clinical neuropsychological tasks and experimental working memory and executive function tasks. The results revealed that a history of mTBI significantly predicted poorer performance in the areas of verbal working memory and decision-making. Depression significantly predicted poorer performance in executive function related to serial updating. In contrast, the commonly used clinical neuropsychological tasks were not sensitive service-related conditions including mTBI, PTSD, and depression. The differing performance patterns observed between the clinical tasks and the more complex experimental tasks support that researchers and clinicians should use tests that sufficiently tax verbal working memory and executive function when evaluating the subtle, higher-order cognitive deficits associated with mTBI and depression.

Description
An increasing number of military veterans are enrolling in college, primarily due to the Post-9/11 GI Bill, which provides educational benefits to veterans who served on active duty since September 11, 2001. With rigorous training, active combat situations, and exposure to unexpected situations, the veteran population is at a higher risk for traumatic brain injury (TBI), Post Traumatic Stress Disorder (PTSD), and depression. All of these conditions are associated with cognitive consequences, including attention deficits, working memory problems, and episodic memory impairments. Some conditions, particularly mild TBI, are not diagnosed or treated until long after the injury when the person realizes they have cognitive difficulties. Even mild cognitive problems can hinder learning in an academic setting, but there is little data on the frequency and severity of cognitive deficits in veteran college students. The current study examines self-reported cognitive symptoms in veteran students compared to civilian students and how those symptoms relate to service-related conditions. A better understanding of the pattern of self-reported symptoms will help researchers and clinicians determine the veterans who are at higher risk for cognitive and academic difficulties.

Description
The emotional enhancement of memory (EEM) has consistently suggested that memory performance is enhanced for positively and negatively valenced stimuli. Heightened arousal and activation of the noradrenergic system facilitates encoding and the formation of memory traces. However, this EEM can become maladaptive when coupled with the heightened noradrenergic activity associated with posttraumatic stress disorder (PTSD). This heightened noradrenergic response can result in chronic intrusive memories of past traumatic events. This study aims to explore overall recall, retrieval dynamics, output editing, and intrusions as a function of emotional content and prior history with traumatic experiences. Undergraduate students (N=249) from Arizona State University completed a battery surveys measuring PTSD symptomatology and other related constructs including anxiety, depression, and trauma. Participants then completed a memory task, an externalized free recall task for multiple study-blocks utilizing word list stimuli. During recall, participants were instructed to report every word that came to mind regardless of whether it was present or not in the most recent study-block, then make a judgment about recent-list membership. Main effects of valence were found for recall accuracy, intrusion generation, and successful editing. This suggests that the emotional enhancement of memory does in fact play a role in intrusion generation and the ability to edit out false recollections. Only depression levels resulted in a significant interaction effect with valence, specifically when measuring intrusion generation. This suggests that trauma level does not play a significant role in emotional intrusion memory.

Description
Posttraumatic stress disorder is a psychiatric disorder that can develop after exposure to a traumatic event, and it can cause affected individuals to relive the associated event through flashbacks or nightmares. This project centers around the prevalence of PTSD in parents of infants admitted to the neonatal intensive care unit. Past research has shown that these parents are at increased risk of developing traumatic stress symptoms, with affliction rates as high as 53% in mothers and 33% in fathers (Hua et al., 2018). With this statistic as a catalyst, the present text has a variety of aims, all hinging on the goal of easing the NICU journey for parents. This thesis explores the different types of therapy used in the treatment of traumatic stress, with a focus on trauma-focused cognitive behavioral therapy (TF-CBT) and eye movement desensitization and reprocessing (EMDR) as these were shown to be the most effective in past research. A compilation of resources was also gathered that can now be distributed to NICU parents, including information on PTSD, how to access a therapist, and other helpful articles. An additional component of this project included the administration of a survey to NICU parents to gain a better understanding of their stress levels, what resources were most helpful to them, what barriers limited their ability to seek help, and their thoughts on a text-messaging resource service. Institutional IRB approval was received for this survey. The survey indicated that parents were very stressed when admitted to the NICU, but their stress levels tend to decrease over time. Parents also faced a variety of barriers, with the need to return to work or maintain a busy schedule being the most pervasive. Additionally, an analysis was completed on federal legislation relating to healthcare and the NICU experience. Furthermore, special considerations for limited English proficient (LEP) families were also considered. The paper concludes with steps that should be taken, in both research and action, to improve on the NICU experience for at-risk parents. The implementation of a text-messaging resource service for NICU parents was desired by survey respondents and is a recommended next step. Changes in policy surrounding insurance reform and longer, paid family leave would also be beneficial. Training of NICU staff on how to provide resources and communicate sensitively and effectively with parents is also crucial if the current situation is to be improved. There are definitive steps that should be taken immediately to ease the journey and provide comfort for NICU parents.
