Relational Savoring Among Intimate Partners Of Cancer Patients, Adrianna Elyse Holness

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that intimate partners of cancer patients experience similar, if not higher, levels of distress and depression than the patient with regards to the cancer diagnosis. This stress can impact the quality of the relationship and the subsequent care and attention given to cancer patients. As such, identifying factors that can enhance marital relationships during times of illness is key. This project was created in order to assess the efficacy of a brief, portable intervention for improving relational quality among the intimate partners of cancer patients. In this project, we examine the effects of relational savoring, relative to two …

The Effects Of Seizure Modeling And Polyphenols On Behavior In Bang-Sensitive Drosophila, Alphonso A. Smith

Loma Linda University Electronic Theses, Dissertations & Projects

Epilepsy is a worldwide public health concern associated with debilitating neurological, cognitive, and psychosocial consequences. Current antiepileptic drugs can have debilitating side effects and new treatments are needed for individuals with pharmaco-resistant seizures like those observed in temporal lobe epilepsy (TLE). Ellagic acid (EA), a polyphenol present in several fruits and nuts, has shown beneficial effects in rodent models of epilepsy and anxiety, possibly mediated through GABAergic pathways. Bang-Sensitive Drosophila mutants model epileptic seizures following mechanical shock and provide a high-throughput alternative to costly rodent studies. The objectives of this study were to: 1) examine the effectiveness of seizure modeling …

Stress, Depression, Social Support, And Help-Seeking In College Student-Athletes, Clint H. Norseth

Loma Linda University Electronic Theses, Dissertations & Projects

Student-athletes have been identified as a distinctive sub-population in universities and colleges that face unique stressors and pressures that may put them at risk for developing mental health problems, including depression, when compared to student non-athletes. However, student-athletes have been found to seek help from mental health professionals less often than student non-athletes. Studies of college students in the general population have shown that social support networks can play an important part in “buffering” or moderating the effect of stress on both depression and help-seeking, which may also be the case for student-athletes. The purpose of the current study is …

The Effect Of Language On Cognition In An Acculturated American Sample Of Healthy Older Adults, K'Dee D. Elsen

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Older adults are not only the fastest growing segment of the population (~841 million worldwide) and continually increasing, but are of special concern due to the numerous age-associated deficits, especially those on cognition. Research indicates that knowing multiple languages may act as a protective factor against the deleterious effects of cognitive aging. Objective: The purpose of the current study is to examine whether multilingualism protects against the effects of cognitive aging on the domains of executive functioning, linguistic processing, attention, memory, and visuospatial functioning. Methods: Participants were 312 healthy older adults (68% female) from the Walnuts and Healthy Aging …

The Effects Of Poverty And Allostatic Load On The Development Of Chronic Disease, Natali Do

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that there is a significant impact of poverty on poor health outcomes. Poverty is associated with limited access to education and healthcare, increased exposure to violence, and chronic stress that contribute to the development of chronic diseases. The poverty and chronic disease relationship is potentially associated with chronically elevated stress biomarkers. The present study investigated the relationship between demographics, poverty (during childhood, young adulthood, and mid/late adulthood), allostatic load—a cumulative measure of system dysregulation—and the Charlson Comorbidity Index, a measure of chronic disease and mortality, using data from the Biopsychosocial and Religion and Health Study (BRHS; Lee et …

Erp And Theta Activity Associated With Facial Emotion Memory, Shaina Roxanne Herman

Loma Linda University Electronic Theses, Dissertations & Projects

Facial emotion recognition is an important component of daily functioning and is highly connected to the social element of human interaction. At present, it is not clear whether initial stimulus encoding or memory maintenance of the face promotes accurate facial emotion memory. The purpose of this study was to explore the mechanisms of facial affect memory. Specifically, we aimed to compare whether type of emotion, length of delay interval, or robustness of encoding the initial stimulus were associated with accurate facial emotion recognition and memory. A task of explicit emotion memory was given to 30 participants. A visual stimulus of …

Parental Stress, Emotion Regulation, Meta-Emotion, And Changes Following An Mbsr Intervention, Yangmu Xu

Loma Linda University Electronic Theses, Dissertations & Projects

Parents of children with developmental delays (DD) have consistently reported higher rates of parental stress (Dabrowska & Pisula, 2010; Oelofsen & Richardson, 2006). Difficulties with child emotion regulation are often exhibited among children with DD, and the relationship between parental stress and child emotion regulation may be bidirectional. Previous studies have found that underlying thoughts about parent’s own emotions is an important construct that has a direct impact on parental emotional wellbeing and child emotion regulation (Gottman et al., 1996). Furthermore, previous studies suggest that Mindfulness-Based Stress Reduction (MBSR), an empirically supported stress-reduction intervention, is efficacious in reducing parenting stress …

Role Of Cultural And Psychological Factors Influencing Diabetes Treatment Adherence, Sonika Kravann Ung

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic diseases are the leading causes of disability worldwide although health complications can be prevented with lifestyle change (CDC, 2013). Type 2 diabetes is a growing global epidemic, and its prevalence is predicted to increase from 6.4% (285 million adults) in 2010 to 7.7% (439 million adults) by 2030 (Shaw, Sicree, & Zimmet, 2010). Given the reality of cultural diversity in contemporary society, the aim of this study was to address the need for research that integrates both cultural and psychological factors with behaviors central to diabetes control among culturally diverse populations (Betancourt & López, 1993; Betancourt, Flynn, Riggs, & …

A Longitudinal Study Of The Reciprocal Relationship Between Ever Smoking And Urgency In Early Adolescence, Jessica L. Burris, Elizabeth N. Riley, Gabriella E. Puleo, Gregory T. Smith

Psychology Faculty Publications

Background—Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction.

Methods—Participants (n=1906; 90% 10–11 years old, 50% female, 39% racial minorities at …

Cross-Lagged Relations Between Motives And Substance Use: Can Use Strengthen Your Motivation Over Time?, Christine A. Lee, Karen J Derefinko, Heather A. Davis, Richard S. Milich, Donald R. Lynam

Psychology Faculty Publications

Motives for substance use have garnered considerable attention due to the strong predictive utility of this construct, both in terms of use and problems associated with use. The current study examined the cross-lagged relations between alcohol use and motives, and marijuana use and motives over three yearly assessment periods in a large sample (N = 526, 48% male) of college students. The relations between substance use and motives were assessed at each time point, allowing for the examination of these inter-relations over time. Results indicated different trends based on the type of substance. For alcohol use, cross-lagged trends were …

Characteristics Of Repetitive Thought Associated With Borderline Personality Features: A Multimodal Investigation Of Ruminative Content And Style, Jessica R. Peters, Tory A. Eisenlohr-Moul, Brian T. Upton, Nina A. Talavera, Jacob J. Folsom, Ruth A. Baer

Psychology Faculty Publications

Increased ruminative style of thought has been well documented in borderline personality disorder (BPD); however, less is known about how the content of rumination relates to domains of BPD features. Relationships between forms of rumination and BPD features were examined in an undergraduate sample with a wide range of BPD features. Participants completed self-report measures of rumination and a free-writing task about their repetitive thought. Rumination on specific themes, including anger rumination, depressive brooding, rumination on interpersonal situations, anxious rumination, and stress-reactive rumination were significantly associated with most BPD features after controlling for general rumination. Coded writing samples suggested that …

Delay Discounting As An Index Of Sustainable Behavior: Devaluation Of Future Air Quality And Implications For Public Health, Meredith S. Berry, Norma P. Nickerson, Amy L. Odum

Psychology Faculty Publications

Poor air quality and resulting annual deaths represent significant public health concerns. Recently, rapid delay discounting (the devaluation of future outcomes) of air quality has been considered a potential barrier for engaging in long term, sustainable behaviors that might help to reduce emissions (e.g., reducing private car use, societal support for clean air initiatives). Delay discounting has been shown to be predictive of real world behavior outside of laboratory settings, and therefore may offer an important framework beyond traditional variables thought to measure sustainable behavior such as importance of an environmental issue, or environmental attitudes/values, although more research is needed …

Spirituality Within Reach: A Pathway Through Meditation, Serena C. Cyr

Antioch University Dissertations & Theses

Meditation is an ancient spiritual practice that has been demonstrated to be beneficial in reducing chronic pain, substance use, and eating disorders, as well as aiding in the treatment of sleep disorders, cancer, and psychological distress. In an effort to enhance the benefits, many contemporary meditation practices have been secularized, focusing on the cognitive, the psychological, and the emotional components, while de-emphasizing the spiritual aspects of meditation. However, spiritual meditation practices also demonstrate benefits, including stress reduction, improved emotional well being, increases in pain tolerance, reductions in mental health symptoms, and increased faith. However, little is known regarding the effects …

Sex Trafficking Survivor, Pro-Life Advocate, Darlene Pawlik

Dignity: A Journal of Analysis of Exploitation and Violence

I was conceived by rape. I was mentally, physically and sexually abused as a child. I endured four years of juvenile sex trafficking. These experiences shaped my views on abortion and pro-life issues. Drawing from my personal experience and the experiences of others, as well as referring to empirical evidence, I set forth the position that children conceived through sexual violence are no less deserving of protection than those conceived in loving relationships. Preserving the health and dignity of sexual abuse survivors is important and supportive help is needed.

The New American Slavery: Capitalism And The Ghettoization Of American Prisons As A Profitable Corporate Business, David A. Liburd

Dissertations, Theses, and Capstone Projects

The labor of enslaved Africans and Black Americans played a large part in the history of colonial America, with the American plantation being the epicenter for all that was to be produced. While the two have never been completely tied together, capitalism and modern day slavery have been linked with one another. Some analysis sees slavery as a remote form of capitalism, a substitute, to an antiquated form of labor in the modern world.

Slave plantations adopted a new concentration in size and management, referred to by W.E. DuBois as a change "from a family institution to an industrial system."1 …

The Effects Of Social Power Bases Within Varying Organizational Cultures, Ayanna Cummings

Dissertations, Theses, and Capstone Projects

This study focuses on social power in the context of organizational culture and how this relationship impacts outcomes of follower compliance and trust. Power is the ability to direct or influence the behavior of others or a course of events (Handgraaf, et al., 2008). There are six different types of social power, including informational, referent, legitimate, coercive, rewarding, and expert (Fontaine & Beerman, 1977). Each type of social power may lead to varying psychological outcomes, such as compliance, satisfaction, and agreement. To date, the empirical literature has not fully addressed the issue of whether one type of power is more …

Aberrant Salience And Probabilistic Reasoning In Distressing Attenuated Positive Psychotic Symptoms: An Examination Of A Two Factor Model, Huw Green

Dissertations, Theses, and Capstone Projects

Theoretical psychological models of positive psychotic symptoms have increasingly emphasized the interaction of multiple cognitive factors. Research into delusions in particular has focused on the interaction of two factors; a perceptual anomaly that gives rise to a need for explanation, and a bias toward premature acceptance of a hypothesis. Recently this two factor approach has been applied to positive psychotic symptoms more broadly. Two candidate factors have received extensive theoretical and empirical interest. The aberrant salience hypothesis posits that salience regulation, mediated by dopamine, goes awry in psychosis, giving rise to a generalized sense of undue significance that is applied …

Semantic Attention: Effects Of Modality, Lexicality And Semantic Content, David Britton

Dissertations, Theses, and Capstone Projects

Since the discovery of the Stroop Effect in 1935 questions about the role of language vs. non-lexical stimuli in selective attention remain. Early researchers attributed the powerful distracting influence shown in the Stroop task, naming the color in which a spelled word is printed when incongruent with the color name the word spells, to an automaticity of language that gives it privileged access to meaning, but many others since have shown various ways to reduce or even reverse this distracting effect of an incongruent word. This study addresses this by using EEG to record neural activity along with reaction time …

The Behavioral Effects Divorce Can Have On Children, Wanda M. Williams-Owens

Dissertations, Theses, and Capstone Projects

According to a statistical study (Cherlin et al. 1991) 40% of children who live in the United States will experience parental divorce before they reach the age of 18. Consequently, many children are affected by the process of divorce and its finalization. When my daughter was just nine years old, she asked incredulously why my husband and I were the only married couple in our neighborhood? After twenty-two years of marriage, I realized long-term marriages in my community are not conventional. When parents’ divorce, children often face the loss of one parent's constant presence and economic stability; as a result, …

The Long-Term Consequences Of Child Abuse And Neglect In Men, Robert A. Beattey Jr.

Dissertations, Theses, and Capstone Projects

Research indicates that the annual incidence of child maltreatment is around 10% and that more than one-quarter of children have, at least indirectly, experienced some form of violence. Prospective studies find that in high-income countries, like the United States, there are moderate correlations between childhood maltreatment and low educational achievement, low skilled employment, depression, suicide attempts, and alcohol problems, as well as strong correlations with obesity, behavior problems in childhood and adolescence, and criminal behavior. Despite the high costs of child abuse and neglect—both direct and indirect—and decades of research and public health, justice, and social service investment in prevention …

Who Posts Selfies And Why?: Personality, Attachment Style, And Mentalization As Predictors Of Selfie Posting On Social Media, Nancy Adler

Dissertations, Theses, and Capstone Projects

This study examines the phenomenon of selfie posting on social media and its relationship to narcissism, the Dark Triad, impulsivity, attachment style, rejection sensitivity, and reflective functioning. The sample was made up of 499 participants who completed an online survey consisting of personality measures and open- and closed-ended questions about selfie posting behavior. Data were analyzed using a negative binomial regression model.

Results: The study found that individuals with high levels of the Dark Triad trait of psychopathy post more selfies on social media than do individuals with low levels of the trait. The Dark Triad trait of narcissism was …

Racial Microaggressions And Health Status: The Moderating Effect Of Emotion Regulation, Kristin C. Davidoff

Dissertations, Theses, and Capstone Projects

The current study seeks to explore the relationship between racial microaggressions and physical and mental health. Significant racial disparities in health status persist in the United States (U.S. Department of Health and Human Services, 2013). Previous research asserts that racial discrimination negatively impacts physical health (Williams, Neighbors, & Jackson, 2003), and studies of subtle discrimination support an inverse relationship with mental health (Borrell et al., 2006). The immediate process following the commission of a microaggression and the target’s internal response may have significant consequences for physical and mental health. The purpose of the current study is twofold: (1) to examine …

Are You With Me? The Impact Of Losing A Conversation Partner’S Attention To A Mobile Device, Zachary A. Geller

Dissertations, Theses, and Capstone Projects

This study examined the impact of a cell phone interruption on participants’ emotional experience during a conversation, using the Thematic Apperception Test (TAT) (Murray, 1943) as a measurement instrument. The study explored whether or not, after losing their conversation partner’s attention to a cell phone, subjects would: tell stories reflecting less adaptive representations of relationships with oneself and others, as measured using a social cognition and object relations rating, SCORS (Stein et al, 2011); tell stories containing more negative emotional words, as measured using a linguistic inquiry software, LIWC (Pennebaker, 2001); and tell stories containing fewer words total.

Methods: …

The Nucleus Accumbens Core Dopamine D1 And Glutamate Ampa/Nmda Receptors Play A Transient Role In The Performance Of Pavlovian Approach Behavior, Veronica Dobrovitsky

Dissertations, Theses, and Capstone Projects

The role of the nucleus accumbens core (NAc core) continues to be redefined with newly acquired data on neurochemical mechanisms mediating the learning and performance of behavior. Previous empirical data showed that dopamine transmission at the D1 receptor (D1R) plays a transient role in the expression of learned Pavlovian approach behavior. Here we show that, prior to overtraining, dopamine activity at D1Rs specifically within the NAc core is critical for the performance of approach behavior elicited by the recently-acquired reward-paired cue. Blockade of D1Rs in the NAc core, but not the dorsomedial striatum or NAc shell, disrupted approach responses during …

Dreams And The Maternal Imaginary: From Nostalgic Intersubjectivity To Mourning, Julie Ackerman

Dissertations, Theses, and Capstone Projects

This dissertation concerns the history of psychoanalytic thinking about dreams. It is about both the psychic function of dreams and their theoretical function, or the function that they have served within psychoanalytic discourse. It begins with a consideration of the significance of the dream in classical thinking, where it was conceptualized as a psychic emergence in the context of maternal absence. It traces the way in which the rise of object relational paradigms led to the reconceptualization of the dream in relation to the presence of the maternal mind rather than the absence of the maternal body. It describes how …

Activation And Habituation Of The Cingulate Cortex During Emotion Processing In Healthy Controls, Borderline, And Schizotypal Personality Disorder, Emily Balevich

Dissertations, Theses, and Capstone Projects

Disturbances in emotional functioning are central features of the clinical profiles of both borderline and schizotypal personality disorder (BPD and SPD, respectively). BPD is characterized by a high sensitivity to emotional stimuli and unusually strong and long-lasting reactions, indicative of impaired habituation to emotional stimuli (Linehan, 1993). Previous research suggests that SPD patients demonstrate limbic hyper-reactivity to unpleasant stimuli, at least initially, but intact habituation to repeated presentation of unpleasant stimuli (Hazlett et al., 2012). The cingulate cortex supports various aspects of emotion processing and regulation, and abnormalities of this region have been related to emotion dysfunction in SPD and …

Does The Career Adaptation Process Change As A Function Of An Employee's Age Or Employment Gaps? An Investigation Of Relationships Among Personal Resources, Contextual Factors, Coping Behaviors, And Career Success, Hilal Erkovan

Dissertations, Theses, and Capstone Projects

The goal of the current research was to enhance understanding of the career adaption process by developing and testing a new psychological framework by integrating three contemporary career theories (i.e., Protean, Boundaryless, and Social Cognitive Career (SCCT) theories). All of these career theories emphasize adaptability and agency as central constructs and stress career self-management as part of having a contemporary mindset because taking control of your career is important. To understand the adaptation process, antecedents and consequences of job-related coping behaviors, which are defined as cognitive and behavioral efforts to manage specific external and/or internal demands, were investigated. The model …

The Contributions Of Child And Romantic Attachment To Sleep Quality, Karen Estefane

Dissertations, Theses, and Capstone Projects

Little is known about the relation between attachment and sleep, although both develop around the first year of life and mutually influence each other. Furthermore, attachment styles and dimensions have been associated with sleep difficulties in both childhood and adulthood. However, these findings have not been consistent, especially among dismissing individuals. In addition, the specific contributions of both child and romantic attachment to sleep quality have not been investigated thus far. This cross-sectional study aims to examine the ways child and romantic attachment are associated with sleep quality. A sample of 671 heterosexual residents of the United States, aged 18 …

Harm And Victim Age As Factors In The Determination Of Intentionality And Culpability, Donal David Barnard Jr.

Dissertations, Theses, and Capstone Projects

In the United States criminal justice system, jurors are directed to determine a defendant’s guilt beyond a reasonable doubt by establishing both the act of committing a crime (actus reus) and the culpable mental state of the defendant (mens rea), that is, the defendant’s intentionality. The role of a juror in a criminal case is that of a factfinder, deciding whether the two elements of the crime have been met. Criminal cases where jurors are asked to decide the facts vary in the harm that resulted. The more severe the harm, the greater the perceived injustice. This …

The Impact Of Spirituality And Trauma On Appraisals Of Psychotic-Like Experiences, Kathleen Isaac

Dissertations, Theses, and Capstone Projects

Background: A substantial portion of the general population (2.5% to 31.4% internationally) reports psychotic-like experiences, which are paranormal, psychic or bizarre perceptual experiences such as voice hearing, or holding strong beliefs (i.e. superstitions) that are neither experienced as pathological nor indicative of a psychotic disorder. Cognitive models of psychosis suggest that the cognitive appraisal (i.e. personal interpretation) of the experience may help distinguish non-clinical psychotic-like experiences from clinical psychotic symptoms. This dissertation attempted to add to cognitive models by assessing whether cultural and personal factors such as spirituality and trauma inform the appraisals of anomalous experiences. This study used a …
