Neuropsychological, Psychosocial, And Mood Outcomes Following Mild Traumatic Brain Injury, Julia L. Evans

Loma Linda University Electronic Theses, Dissertations & Projects

Traumatic brain injury (TBI) in adolescents and adults can result in cognitive, emotional, behavioral and neurological deficits that can persist more than a year after an injury. The aim of the current preliminary study was to use a comprehensive neuropsychological assessment to determine the nature of cognitive impairments and their relationship with specific psychosocial factors, including coping skills and perceived quality of life, following mild TBI (mTBI). Neuropsychological tests administered measured intelligence, pre-morbid intelligence, executive functioning, verbal memory, complex visual construction and non-verbal memory, sustained attention distractibility, and vigilance, verbal learning and memory, fine motor speed, and novel problem solving …

Parental Grief And Loss And The Medical Staff Relationship: A Function Of Attachment, Peter Christopher Gleason

Loma Linda University Electronic Theses, Dissertations & Projects

Each year, too many parents must face the horrific ordeal of having to prepare for the death of their child; thought to be the most traumatic event in the life of an adult (Widger & Picot, 2008). It is in the desperate hours just prior to death that these parents, for many reasons, reach out for support to the medical staff around them. This process, particularly if negative, can leave scars that parents will carry for a lifetime (N. Contro, Larson, Scofield, Sourkes, & Cohen, 2002; Tinsley, et al., 2008). However, there appear to be factors that serve to lessen …

Lateralization Of Emotion, Reaction Time, And Skin Conductance Responsiveness, Kimberley Erin Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in …

Exploring Gender Differences In Online Cancer Support Groups, Natalie Christine Kaiser

Loma Linda University Electronic Theses, Dissertations & Projects

Gender differences in depression and other psychiatric conditions have been widely

documented in the general population (Nolen‐Hoeksema, 2006). Therefore, several studies have

analyzed the differential gender‐based adaptation of a cancer diagnosis. However, there seem to be contradictory results. While some studies have found there to be no gender differences in terms of cancer‐related distress (Beresford et al., 2006; Deimling et al., 2006; Zabora et al., 2001; & Carlson et al., 2004; Matthews, 2003), other studies have found that females tend to display more anxiety and depressive symptoms (Mystakidou et al., 2005; Deimling et al., 2006). Interestingly, limited studies have reported …

The Impact Of Pomegranate On Memory Dysfunction After Cardiac Surgery, Sapna Patel

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Studies have shown a decline in certain cognitive abilities in individuals diagnosed with heart disease of any type or etiology. This decline is observed as the disease progresses (Muller, Grobbee, Aleman, Bots & van der Schouw, 2006; Ernest et al., 2006), as well as after certain interventions, such as coronary artery bypass grafting (CABG) and heart valve surgery. In recent years, there has been a great deal of emphasis on the beneficial effects of pomegranate on health, including diseases of the brain and the heart. Few, however, have explored the impact of pomegranate on cognitive functions. Thus, the current …

Myelomeningocele And The Neuropsychological Functioning Of Bilingual Children, Claudia Resendiz

Loma Linda University Electronic Theses, Dissertations & Projects

Myelomeningocele is the most common and most severe form of spina bifida, affecting the brain and spinal cord of millions of children. Children of Hispanic background have the highest prevalence rate of this condition. Despite this fact, research that examines the cognitive profiles of Hispanic children with myelomeningocele is limited. A review on bilingualism and neurocognitive performance suggests that a cognitive advantage is present among those who are able to learn and utilize two languages. Although some have investigated the neuropsychological performance of children with myelomeningocele, research has yet to examine whether a bilingual cognitive advantage is present among bilingual …

Mrs And Neuropsychological Outcome In Children With Non-Accidental Tbi, Aileen Arratoonian

Loma Linda University Electronic Theses, Dissertations & Projects

Despite the severe and long-term neurological consequences and the prevalence of non-accidental head trauma (NAT) among infants, few empirical studies have specifically examined the neuropsychological consequences in this population of children. The current study examined the relationship between clinical variables, Magnetic Resonance Spectroscopy (1H-MRS), and neuropsychological outcome in this high-risk population of children. Infants and children with a confirmed diagnosis of NAT were recruited by the Division of Pediatric Neurology at Loma Linda University Children’s Hospital and administered a comprehensive follow-up neuropsychological evaluation and neurological exam several months post injury. At the conclusion of the study, there were 13 participants …

Memory For Emotional Images: Mechanisms Of Episodic Processing And Its Psychophysiological Correlates, Gregory E. Devore

Loma Linda University Electronic Theses, Dissertations & Projects

Negative emotional stimuli are usually better remembered than neutral emotional stimuli. Previous examination of binding theory found no differences in recall for pure lists of taboo and neutral words. A similar result was found with equivalent recognition memory performance between pure lists of negative, positive, and neutral images. The current research is designed to test the predictions of binding theory using negative and neutral visual stimuli in mixed lists. A rapid serial visual presentation paradigm and recognition memory item-discrimination tasks are used. Binding theory predicts differences in recognition memory performance between arousing and neutral images in mixed lists, but not …

Religious Coping And Depression Among Blacks And Whites After Sexual Abuse, Richelin Dye

Loma Linda University Electronic Theses, Dissertations & Projects

According to the theory of Fundamental Assumptions, childhood sexual abuse survivors have more depressive symptoms as a consequence of disrupted assumptions relating to optimism and mastery (Janoff-Bulman, 1992). This study tested whether positive religious coping preserves the fundamental assumptions to decrease depressive symptoms. In contrast, negative religious coping was posited to challenge assumptions. These hypotheses were tested in 2949 women from the Biopsychosocial Religion and Health study of which 246 reported childhood sexual abuse (CSA) with no childhood physical abuse and no adult sexual assault. Across all participants, positive religious coping (benevolent God reappraisal, collaborative religious coping, and spiritual connection) …

Inpatient Stroke Rehabilitation: Ethnic And Psychosocial Predictors Of Recovery Outcome, Anna Olga Wong

Loma Linda University Electronic Theses, Dissertations & Projects

As the new focus on preventative medicine has emerged, research continues to expand on diseases that impact physical and cognitive functioning, lead to long-term disability, and increase the risk of mortality. Stroke or cerebral vascular accident (CVA) has been identified as one of such diseases by the Centers for Disease Control (2007). Past literature has identified disparities between ethnicity, socioeconomic status, and other diseases in the recovery of stroke. The aim of the current study was to investigate the effects of ethnicity and psychosocial factors on stroke recovery during inpatient rehabilitation. The study included 446 patients who had suffered an …

Expanded Behavioral Model For Online Support Services, Laura Boxley

Loma Linda University Electronic Theses, Dissertations & Projects

The rapid expansion of online technologies and health resources has created opportunities to develop broadly available interventions to address the needs of the modern patient. This study proposes a theoretical structure based on Andersen's Individual Determinants of Health Service Utilization Model to describe who is using online support and how it is being used. Also unique to this analysis was the use of objective behavioral data to describe and predict website utilization, and linguistic analysis to evaluate the content of what is shared in online groups. Eighty-four men and women completed baseline evaluations and were randomized into either online support …

Longitudinal Behavioral Assessment Of Neonatal Traumatic Brain Injury, Joel Kamper

Loma Linda University Electronic Theses, Dissertations & Projects

Traumatic brain injury (TBI) in children and infants is a primary cause of cognitive and behavioral problems that can persist through adulthood. In this study, the long-term behavioral effects of neonatal and juvenile TBI (jTBI) were characterized using mice. At an age of post-natal 7 or 10 days, mice underwent moderate or severe closed skull impact or sham surgery. Behavioral testing was conducted at 6 and 8 months post-injury. Tests administered included the open field activity (general activity levels), zero maze (anxiety), forced swim (depression), rotarod (coordination and balance), and water maze (general/spatial learning). jTBI mice showed elevated activity levels, …

Cultural And Personal Influences On Body Satisfaction In Mexican American Women, Melissa Y. Snyder

Loma Linda University Electronic Theses, Dissertations & Projects

The current study extended prior research examining the impact of acculturation on body satisfaction while integrating possible mediating variables for a sample of Mexican American women. Specifically, the study examined the relationships among acculturation (ARSMA-II), acculturative stress related to racism and immigration (HWSSS), objectified body consciousness (OBCS), SES, age, BMI, and body dissatisfaction. Outcome measures of body dissatisfaction included the EDI subscales of Body Dissatisfaction, Bulimia, Drive for Thinness, and Ineffectiveness, as well as the Body Esteem Scale (BES). Participants were 352 women of Mexican descent between the ages of 18 and 50 years recruited through California State University, San …

Modeling Treatment Outcomes In Eating Disorders, Kathryn Grace Truitt

Loma Linda University Electronic Theses, Dissertations & Projects

Eating disorders are notoriously difficult and costly to treat, with only 40% of individuals with an eating disorder making a full recovery. Individually Tailored Service Allocation provides a dynamic treatment model defined by empirically accepted theory and consistently informed by data provided by the patient. The use of patient feedback allows for the tailoring of individual treatment plans to meet the unique and varied needs of each patient. Hierarchical Linear Modeling was used to examine the effect of Individually Tailored Service Allocation on eating disorder treatment outcomes. A total of 51 adult women meeting diagnostic criteria for an eating disorder …
