Emotional Response To Auditory And Visual Stimuli, Amy Pitchforth

Loma Linda University Electronic Theses, Dissertations & Projects

Emotion can be studied by measuring physiological, behavioral, and verbal responses to specific stimuli. In current research, it is most common to use visual stimuli to measure the emotional response. One of the most common sets of stimuli used for this purpose is the International Affective Picture Systems (IAPS). An additional set of stimuli, the International Affective Digital Sounds (IADS), was created to be an auditory equivalent of the IAPS. The present study sought to compare the emotional response (measured with Heart Rate, Skin Conductance, and a self-report measure of emotion called the SAM) to sounds from the IADS and …

Effects Of Acculturation On Hiv/Aids Sexual Risk Behaviors Among Asian And Pacific Islander (Api) Women, Margaret Cabotage Salud

Loma Linda University Electronic Theses, Dissertations & Projects

Background. In the US women are the fastest growing group for sexually transmitted infections (STIs), including HIV and AIDS. In addition, the estimated AIDS cases among female adults and adolescents, aged 13-19, increased from 7% in 1985 to approximately 26% in 2002. Most infections occur by heterosexual transmission with 53% occurring through contact with a high-risk sexual partner. While overall HIV/AIDS rates in the Asian Pacific Islander (API) community remain low, they are rising and HIV testing rates, one of the major prevention strategies for HIV, are lower than that of other populations. Furthermore, very little is known about APIs …

Parental Divorce, Attachment, And Self-Other Conceptualization, Julia A. Hewett

Loma Linda University Electronic Theses, Dissertations & Projects

The formation of strong attachment bonds in childhood and adolescence has a significant effect on adult self and other concepts operationalized here as self-esteem and hostility. These self-other conceptualizations are posited to facilitate the formation of successful relationships and well-being in adulthood. To determine whether parental separations before the age of 16 years disrupt attachment bonds and subsequent self-other conceptualizations, participants from three naturally formed parental marital status groups were compared on attachment, self-esteem and hostility: divorced parents (N = 622), married parents (N = 7, 424), or divorced but remarried parents (N = 313). Individuals who had divorced or …

The Role Of Ambient Air Pollution In The Occurrence Of Emphysema, Shiva Metghalchi

Loma Linda University Electronic Theses, Dissertations & Projects

Emphysema is the most common cause of death from respiratory disease in the United States. Emphysema is most common among people aged 50 and older. Those with a genetic predisposition to emphysema may experience the onset as early as their thirties or forties. Men are more likely than women to develop emphysema, but female cases are increasing as the number of female smokers rises.

In the past few years, etiological and pathogenic research has been carried out in an attempt to determine the reason for an increase in deaths and other health problems associated with air pollution, and there have …

Neuropsychological Symptoms Associated With Multiple Shunts, Jared Jackson

Loma Linda University Electronic Theses, Dissertations & Projects

Hydrocephalus is the excessive accumulation of cerebrospinal fluid within the cranium which may result in increased intracranial pressure, dilation of cerebral ventricles and displacement of adjacent brain structures. Ventriculoperitoneal shunting is often needed to treat hydrocephalus. Patients with Ventriculoperitoneal shunts have been found to have IQ scores below the mean of the general population. In addition, many of these patients experience shunt infections or other complications that require shunt replacement. Shunt replacements and shunt infections have been associated with additional deficits in intellectual functioning. However, previous research has failed to address the neuropsychological ramifications of shunt infections and shunt replacements. …

Convergent Validity Of Self Reported Physical Activity With A Seven Day Recall, Benjamin J. Silber

Loma Linda University Electronic Theses, Dissertations & Projects

Accurate assessment of physical activity is important to studies interested in the relationship between physical activity and other variables. Questionnaires are the only feasible means for large-scale sampling but such self-report measures require validation due to their inherent subjectivity. The Adventist Health Study-2 (AHS-2) survey includes exercise items that were validated in the present investigation. A calibration study examined self-reports of exercise with two phone calls to 1,000 participants in which an interview-assisted 7-day physical activity recall was completed by a random sample of AHS-2 participants. Inter-index correlations both within the survey and between the survey and the 7-day physical …

Psychological Profiles In A Female Bariatric Surgery Sample, Aimee L. Donato

Loma Linda University Electronic Theses, Dissertations & Projects

Morbid obesity is an epidemic. Current literature suggests that people with morbid obesity tend to show increased levels of psychological dysfunction. This is especially pertinent to the clinicians who work with morbidly obese patients who seek bariatric surgery as the method for weight control. Surgery should be performed on patients who are psychologically ready to adjust to the stringent post-operative lifestyle.

The purpose of the present study was (1) to compare two groups of bariatric patients (a White group and a non-White group) on pre-surgery measures: specific scales on the Millon Behavioral Medicine Diagnostic (MBMD), the Beck Depression Inventory II …

Assessing The Prevalence Of Inadequate Nutrient Intake Among Vegetarians And Non-Vegetarians Using The Estimated Average Requirement : Results From The Adventist Health Study-2 Calibration Study, Choon Chew Teo

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Studies have shown that vegetarians have lower risk of chronic diseases and longer lifespan. Yet when mean intake of vegetarians was compared with the Recommended Dietary Allowance (RDA), it was reported that vegetarians were inadequate in certain nutrients. With the recent establishment of the Estimated Average Requirement (EAR), the new reference standard for assessing adequacy of population intakes, nutrient adequacy of the vegetarian diet should now be reassessed.

Daily number of servings for each food group of the food guides have usually been theoretically computed based on intakes suggested in menus or cookbooks. We attempted to use the actual …

Risk For Developmental Delay In Non-Syndromic Craniosynostosis, Sharis Nazarian

Loma Linda University Electronic Theses, Dissertations & Projects

Non-syndromic craniosynostosis is a craniofacial condition where there is a premature fusion of a calvarial suture. There are four subtypes of craniosynostosis, each one reflecting the suture that is fused (metopic, sagittal, coronal synostosis, and lambdoid synostosis). Research suggests that non-syndromic craniosynostosis is associated with an increased risk of developmental delay, behavioral problems, and learning disabilities. This was an archival study with 30 participants being treated at the Loma Linda University Children’s Hospital Craniofacial Team Center. The purpose of this study was to examine the relationship between risk for developmental delay and type of craniosynostosis using the Bayley Infant Neurodevelopmental …

Ethical Decision-Making Regarding Nonsexual Multiple Relationships, Diana Jochai

Loma Linda University Electronic Theses, Dissertations & Projects

The current American Psychological Association Ethical Principles of Psychologists and Code of Conduct (APA Ethics Code) states that a multiple relationship is established between a psychotherapist and a client when they engage in a relationship (personal or professional) in addition to the therapeutic relationship (AP A, 2002). Evidence that psychologists do become involved in such relationships, sometimes resulting in harm to the client, comes from examination of complaints to professional organizations and licensing boards, and of scant existing research. Remarkably, however, there has been no research to date regarding the ethical decision-making process in which a psychologist engages regarding whether …

Client/Therapist Feedback And The Role Of The Alliance On Psychotherapy Outcomes, Elizabeth Preston Cisneros

Loma Linda University Electronic Theses, Dissertations & Projects

Through a system of patient-focused outcomes research which has employed a quality assurance system for tracking client progress in therapy, there has been consistent evidence that utilizing the system to identify those who are not responding to treatment and warning their therapist about the client’s risk significantly improves client outcomes in psychotherapy. Although outcomes have been improved, significant proportions of clients have treatment failures or see no improvement in therapy. Moreover, feedback to therapists appears to be most effective in improving outcomes for the minority of clients who are already at risk of treatment failure.

Attempts to augment the feedback …

The Use Of The Minnesota Multiphasic Personality Inventory-Ii (Mmpi-2) In Pre-Employment Evaluations, Ana M. Gamez

Loma Linda University Electronic Theses, Dissertations & Projects

Psychological testing is an important facet in the selection and hiring processes of law enforcement and public safety personnel. Research in this area suggests that the MMPI-2 scales have been correlated with problematic behavior among police officers, poor job performance, and officer misconduct. This study examined the extent to which suitability for hire could be predicted by the MMPI-2 scale L (Lie), scale K (correction), Infrequency scale (F), scale 4 Psychopathic Deviate (Pd), scale 6 Paranoia (Pa), scale 7 Psychasthenia (Pt), and scale 9 Hypomania (Ma). It examined whether profile differences emerged as a function of suitability across gender, between …

Post-Traumatic Stress Disorder-Like Symptomatology In Pediatric Intensivists, Dina Gabriella Cuervo

Loma Linda University Electronic Theses, Dissertations & Projects

Helping professionals, such as social workers, emergency first responders and medical personnel are susceptible to traumatic stress reactions through indirect exposure to trauma via the traumatized population whom they serve. This phenomenon, known as secondary traumatic stress (STS), mimicking the symptoms of posttraumatic stress disorder, can have an impact on a provider’s work with his/her patient or have longer-term effects such as deciding to leave the profession. This study found that physicians’ level of job stress was the strongest predictor of STS and that this relationship was also influenced by resiliency, ego strength and attachment style. Individuals with higher levels …

Effects Of Orthodontic Treatment On Social Perceptions, Sherry A. Caraveo

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: The purpose of this study was to record first impressions elicited by photographs of orthodontic patients before and after treatment to test the hypothesis that after treatment patients will elicit a more positive first impression.

Methods and Materials: Before (Tl) and After (T2) photographs of six orthodontic patients equally divided by gender and standardized for background facial attractiveness were selected. Three different malocclusions were represented: 1) Class 1 crowded, 2) Class 11 div 1, and 3) Class 111. 108 college students rated each photographed patient on three attributes: physical attractiveness, intelligence and social desirability. Participants recorded their responses on …

Creating Prediction Models For Obstructive Sleep Apnea Based On Gender, Jeffrey Hwang

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Obstructive sleep apnea (OSA) is a common chronic disorder that is characterized by repetitive episodes of airflow cessation or reduction occurring during sleep as a result of partial or complete upper airway obstruction. These recurrent events have a tremendous impact on the cardiovascular system with a multitude of dangerous consequences. Numerous studies have been conducted determining etiological risk factors for OSA including anatomical predictors which have been observed with multiple imaging techniques. Cone beam computed tomography (CBCT) is a low-radiation mode of imaging that can be used to accurately identify anatomical landmarks and measure craniofacial relationships and airway dimensions. …

Validity Study Of The Psychopathic Personality Inventory In A Noncriminal Population, Julie Madeleine Woltil

Loma Linda University Electronic Theses, Dissertations & Projects

The Psychopathic Personality Inventory (PPI) is a self-report measure which was created by Lilienfeld and Andrews (1996) to identify the personality traits of psychopathy in noncriminal populations. These personality traits were grouped into eight subscales in the PPI including Machiavellian Egocentricity, Social Potency, Coldheartedness, Carefree Nonplanfulness, Fearlessness, Blame Extemalization, Impulsive Nonconformity and Stress Immunity. In this study, the relationship between the PPI and four theoretically related concepts (psychopathy, empathy, sensation seeking and driving anger) were examined to evaluate its concurrent and construct validity. A positive correlation was found between the PPI and the Self-Rep0l1 Psychopathy Scale, the Driving Anger Scale, …

Correlating The Slope Of The Vomer With Cephalometric Vectors Of Facial Growth, Ryan Michael Pulfer

Loma Linda University Electronic Theses, Dissertations & Projects

It is important for orthodontists to have a basic understanding of the growth and development of the face. Scott's nasal septal cartilage theory proposes that the cartilage of the nasal septum proliferates along the anterior slope of the vomer bone by interstitial growth, simultaneously pulling and displacing the maxilla downward and forward. It is therefore logical to conclude that the vector of nasomaxillary growth has a geometric correlation with the anterior slope of the vomer bone.

There are no published studies comparing either the anterior or posterior slope of the vomer with any lateral cephalometric landmarks, the vectors of nasomaxillary …

Experimental Models Of Brain Hemorrhage Using Clostridial Collagenase, Tim Lekic

Loma Linda University Electronic Theses, Dissertations & Projects

Stroke is the third leading cause of death and is the leading cause of disability in the United States, and the most severe form is known as intracerebral hemorrhage, which is bleeding into the brain. The goal of this study is to establish novel animal models to buildup foundations for translational research of intracerebral hemorrhage. We, for the first time, established four animal models, including cerebellum hemorrhage, pontine hemorrhage, neonatal matrix hemorrhage and maternal postpartum hemorrhage. Those models are established according to intracerebral hemorrhage patient subpopulations, and characterized the neurobehavioral and morphological outcomes. These studies have established the requisite for …

Development Of A Lung Cancer-Specific Model For Support Group Interest, Laura Testerman

Loma Linda University Electronic Theses, Dissertations & Projects

Despite high levels of both emotional and physical distress and desire for utilization of support group services, lung cancer patients rarely participate in these supportive services. Lung cancer survivors’ interest in and use of supportive psychosocial services remains poorly understood, and Internet-based services may be of particular benefit to this population. The Behavioral Model for Vulnerable Populations, which emphasizes Predisposing (i.e., demographic as well as attitudes about support services), Enabling (i.e., accessibility of services), and Illness (i.e., need for services based on health) factors, was applied to the prediction of survivors’ behavioral intention to participate in face-to-face support groups (F2F) …

Veterans Of The 1st Persian Gulf War: A Study Of Medically Unexplained Symptom Models, Alexis H. Collins

Loma Linda University Electronic Theses, Dissertations & Projects

In 1990-1991, shortly after the Persian Gulf War, a number of veterans began complaining about a wide range of symptoms, the most common of which were; fatigue, headache, sleep disturbance, low mood, and memory loss. These symptoms were similar to those experienced by individuals with Medically Unexplained Illnesses such as Chronic Fatigue Syndrome, Fibromyalgia, Irritable Bowel Syndrome, Multiple Chemical Sensitivity, and Somatoform Disorders. Utilizing structural equation modeling and data gathered from the Gulf War Veterans Health Questionnaire, this study attempted to determine whether symptoms experienced by veterans were best explained as individual items, discrete illnesses, or as a conglomeration of …

The Role Of Unrealistic Optimism In Explaining Preventive Behaviors In High Versus Low Endemic Malaria Settings In Belize, Daniel G. Handysides

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Of all the diseases an individual can encounter in the world, malaria is one of the most destructive. Simple measures like sleeping under a bednet would greatly reduce the burden (Abeku, 2007). When people estimate their risk relative to others, they are most often unrealistically optimistic, which may explain why those at risk often fail to perform behaviors, such as using a bednet that will reduce their risk. However, one study showed that people at high risk for malaria held pessimistic perceptions of their risk for the disease, but the reasons for this finding are unclear (Morrison, Ager, & …

Effect Of Depression On Attention Via Mood Induction In A Healthy Population, Cheryl Mae Calvano

Loma Linda University Electronic Theses, Dissertations & Projects

This project continues research into the cognitive attention of persons with a sad mood similar to that experienced by dysthymia. The project utilizes the Dot Probe Task to evaluate attention to affective stimuli presented in the International Affective Picture Set (IAPS). Participants were psychology students recruited from La Sierra University. Participants completed a word task that intended to induce a sad or neutral mood. The Positive and Negative Affect Scale (PANAS) was used to evaluate the efficacy of the mood induction. Overall, participant’s negative PANAS scale did not differ between groups. Groups differed between administrations of the PANAS on the …

Mental Health And Victimization Experiences In Fibromyalgia: A Literature Review, Eric J. Kloeppel

Loma Linda University Electronic Theses, Dissertations & Projects

Fibromyalgia (FM) is a chronic disorder characterized by widespread musculoskeletal pain, fatigue, and/or multiple tender points located on the neck, shoulders, back, hips, arms or legs that hurt when touched. FM can be a debilitating condition with financial, emotional, interpersonal, and health costs that can affect not only the person diagnosed, but his or her family and friends. Presently, the etiology of FM is largely unknown and there is no definitive cure. Researchers have identified several possible contributing factors in the development and maintenance of FM, including genetics, abnormalities in the neuroendocrine system, and sleep disturbances as well as psychiatric …

Association Between Obesity, Depression, And Inflammation Among Seventh-Day Adventists In The Biopsychosocial Religion And Health Study, Michael Paalani

Loma Linda University Electronic Theses, Dissertations & Projects

The effects of obesity and depression on morbidity and mortality may be mediated by inflammatory processes. Homeostasis within the immune system depends on a balance of pro-inflammatory and anti-inflammatory cytokine molecules, so chronic inflammatory diseases may result from cytokine dysregulation. The target population consisted of 508 Seventh Day Adventists (SDAs) who participated in the Biopsychosocial Religion and Health Study (BHRS), a sub-study of the Adventist Health Study-2. The study was a cross-sectional analysis of the association between obesity, depression, and inflammation after controlling for demographic, socioeconomic, health behavioral, and health status variables among BHRS participants.

Obesity was assessed by body …

Therapeutic Modalities Targeting Neuroinflammation After Neonatal Hypoxia-Ischemia, Nancy Fathali

Loma Linda University Electronic Theses, Dissertations & Projects

Hypoxia-ischemia (HI) occurs in 1-6/1000 live full-term births (Shankaran, 2009). Of those affected, 15-20% will die in the postnatal period, and 25% of survivors will be left with long-term neurological disabilities (Gunn, 2000; Vannucci, 1997; Fatemi, 2009). It has become increasingly clear that peripheral immune cells infiltrate the brain parenchyma as part of the physiological response to tissue damage after HI injury. The interplay between infiltrating immune cells and brain resident cells during the inflammatory response is however dynamic and complex; in that neuro-immune crosstalk, by way of specific molecular mediators, is responsible for both neurodestructive as well as neuroprotective …

Hypoxia And Fetal Programming Of Cardiovascular Dysfunction, Qin Xue

Loma Linda University Electronic Theses, Dissertations & Projects

Human epidemiological studies have shown a clear association of adverse intrauterine environment and an increased risk of ischemic heart disease in later adult life. Of all the stresses to which the fetus is subjected, perhaps the most important and clinically relevant is that of hypoxia. The goal of this project is to test the hypothesis that chronic hypoxia during gestation adversely affects fetal cardiovascular development and impairs cardiac function in offspring. In the first part of project, we tested the hypothesis that chronic hypoxia adversely regulates contractility of fetal pulmonary arteries and veins in sheep residing at high altitude (3,801 …

Aerobic Exercise And Bone Turnover In Trained And Untrained Premenopausal Women, Michelle Prowse

Loma Linda University Electronic Theses, Dissertations & Projects

Regular weight-bearing exercise is recommended for healthy young adults to optimize bone mineral density (BMD) (Physical Activity Guidelines Advisory Committee, 2008). BMD alone however, is not a significant predictor of osteoporosis or fracture risk. While bone turnover markers are used clinically to assess efficacy of pharmacological intervention in individuals diagnosed with osteoporosis, they may also have a role in evaluating acute responses to exercise. The purpose of this dissertation was to compare two groups of premenopausal women, those which are sedentary (low fitness) versus those that are well-trained (high fitness), by BMD and bone turnover markers at rest and the …

Stressors And Coping Mechanisms Of Married Female Physicians : A Qualitative Review, Eva Marie Starner

Loma Linda University Electronic Theses, Dissertations & Projects

Female physicians live and work in a very complex world fraught with professional demands and personal challenges. Twenty-seven married female physicians were interviewed for this study to assess demands and stressors endemic to them and to determine how they manage them. The breadth of this study looked at the demands and stressors of the female physician from the perspective of her work environment, home and family responsibilities, parenting responsibilities, and self-imposed demands in her perceived roles as a working wife and mother. Two main categories emerged during the development of grounded theory: System Challenge and System Adaptation. Additionally, work demands, …

A Critical Constructionist View Of "At-Risk" Youth In Alternative Education, Rachelle Silverstein Touzard

Loma Linda University Electronic Theses, Dissertations & Projects

Family therapists and school counselors are increasingly called upon to provide services for youth in alternative education (Carver, Lewis, & Tice, 2010). Alternative education systems are programs for youth who have been defined as at risk. This study explored the at-risk discourse and asked the questions (a) how do youth and staff define the term at risk, (b) construct their experience in alternative education systems, and (c) experience their relationships with each other.

Combined elements from critical theory and a social constructionist perspective guided this study. A qualitative, grounded theory method was used that included semi structured interviews with …
