How Social Activity Affects Exercise In A Rat Model Of Depression Proneness, Jacqueline Rojas

Modern Psychological Studies

With depression rising worldwide, finding effective, affordable relief is a pressing global public health need. Social activity and physical activity both function as natural depression remedies, but depression can interfere with these activities. This study explores whether an increase in social activity can simultaneously increase voluntary exercise. If so, a single remedy could potentially yield two benefits. Rats were singly or paired housed to model social activity, and voluntary wheel running was measured. Depression proneness was modeled with Occidental Low-Saccharin- Consuming (LoS) rats; relative to high-saccharin-consuming (HiS) rats, LoS rats are more anxious and vulnerable to stress, both of which …

Discrimination, Substance Use, And Cultural Buffers Among Native American College Students, Brenna L. Greenfield

Psychology ETDs

The negative effects of racial discrimination and microaggressions on health have been consistently documented, but only a handful of studies have examined this topic among Native Americans. The goal of this study was to test the Indigenist Stress-Coping Model (Walters, Simoni, & Evans-Campbell, 2002) among Native American college students attending two post-secondary institutions in the Southwestern United States. It was hypothesized that microaggressions would be positively related to substance use, and that cultural factors would attenuate the strength of this relationship. A total of 347 participants (65% female) completed a one-time online survey that included the Microaggressions Scale, the Actualization …

Training "In A Good Way": Evaluating The Effect Of A Culturally Responsive Pre-Training Intervention On Learning And Motivation, Adam Thomas Murry

Dissertations and Theses

Employee Training and Development (T&D) is a crucial component to an organization’s success and its ability to remain competitive. Although researchers in the field have discovered ways to enhance the effectiveness of training programs through the design, delivery, and evaluation process, research has not provided empirically-based recommendations for how to best train individuals whose cultural backgrounds may influence receptiveness of training curriculum. This is particularly relevant for employees whose cultural groups have been historically discriminated against, where cultural norms implicit in the training design may be met with resistance on behalf of the trainees. In the field of multicultural education, …

From Mirroring To World-Making: Research As Future Forming, Kenneth J. Gergen

Psychology Faculty Works

After decades of acrimonious debate on the nature of scientific knowledge, researchers in the human or social sciences are reaching a state of relative equanimity, a condition that may be characterized as a reflective pragmatism. Yet, even while the context has favored the development of new forms of research, the longstanding ocular metaphor of inquiry remains pervasive. That is, researchers continue the practice of observing what is the case, with the intent to illuminate, understand, report on, or furnish insight into given states of affairs. And, while selectively useful, such an orientation is not only limited in potential but subject …

Do Clergy In Hidalgo County, Texas Serve As A Bridge Or Barrier To Mental Health Services?, John C. Park

Loma Linda University Electronic Theses, Dissertations & Projects

Clergy play the role of frontline mental health (MH) workers for many Americans (Ellison et al., 2006; Wang et al., 2005; Winet, Majors, & Stewart, 1979). There is insufficient information in regards to what the clergy believe about MH and how they respond to MH related concerns. What we know indicates that clergy are not sufficiently equipped or trained to respond adequately to people suffering from issues of MH. Using face to face interview process, 301 clergy members of the faith based organizations (FBO) in Hidalgo County, Texas (HCT) were interviewed. Key findings suggest that the clergy engage in significant …

Assessment Of Geriatric Depression: Construction Of A New Screening Inventory, Earl C. Thorndyke Iii

Loma Linda University Electronic Theses, Dissertations & Projects

Geriatric depression is strongly associated with increased healthcare costs, poor treatment outcomes, and mortality. Existing measures of depression in this population do not adequately account for more recent literature describing the presentation of depressed older adults, and thus may result in the underdiagnosis of depression in this population. The current study consistent of the development of a new, updated measure and examined its psychometric properties and potential clinical utility for diagnosing depression in adults over the age of 65. Participants were be recruited from multiple sources, including a community population from residential retirement communities, as well as inpatients and outpatients …

Loma Linda University Electronic Theses, Dissertations & Projects

The adolescent and young adult (AYA) cancer population suffers from many unique medical and mental health challenges. Both medical, psychological and support services play an important role in the lack of improvement in survival rates of this population. The purpose of this project was to identify the unique mental health challenges and treatment needs of the Adolescent and Young Adult (AYA) Oncology population and to evaluate current oncology programs available to this population at Loma Linda University. The project provides guideline recommendations for implementing a comprehensive and developmentally appropriate AYA oncology program at Loma Linda University.

Predictors Of Placement Satisfaction For Foster Youth, Shereen Mcfarlane

Loma Linda University Electronic Theses, Dissertations & Projects

Youth in the foster care system are often removed from their biological families because of challenges to their safety and wellbeing and are often at risk for further placement disruption and poor socio-emotional development. Placement stability is a crucial component to establishing permanency and placement satisfaction might be a contributing factor. This study uses an ecological framework to explore the impact of the foster youth’s ecosystem, such as the foster child, foster parent, child welfare worker, and the placement environment on placement satisfaction. This quantitative study uses secondary data to determine the predictability of these factors on placement satisfaction of …

Modeling Sources Of Teaching Self-Efficacy For Science, Technology, Engineering, And Mathematics Graduate Teaching Assistants, Sue Ellen Dechenne, Natalie A. Koziol, Mark Needham, Larry Enochs

Department of Educational Psychology: Faculty Publications

Graduate teaching assistants (GTAs) in science, technology, engineering, and mathematics (STEM) have a large impact on undergraduate instruction but are often poorly prepared to teach. Teaching self-efficacy, an instructor’s belief in his or her ability to teach specific student populations a specific subject, is an important predictor of teaching skill and student achievement. A model of sources of teaching self-efficacy is developed from the GTA literature. This model indicates that teaching experience, departmental teaching climate (including peer and supervisor relationships), and GTA professional development (PD) can act as sources of teaching self-efficacy. The model is pilot tested with 128 GTAs …

Bibliotherapy As An Intervention For Aggressive Elementary Children, Kari Newman

Theses and Dissertations

This study investigated the effect of bibliotherapy as an intervention for aggressive elementary children at a residential treatment center in the western United States. Bibliotherapy was provided for six children, three boys and three girls, ages 9 to 11, Caucasian and Hispanic, who took part in one of two groups. The study involved a multi-baseline design, beginning with a baseline phase, followed by two separate intervention phases comprised of eight sessions of bibliotherapy. Data gathered from almost daily observations along with pre- and post-intervention ratings of aggressive behaviors indicated that four of the six students demonstrated notable decreases in observed …

Medulla: A 2d Sidescrolling Platformer Game That Teaches Basic Brain Structure And Function, Joey R. Fanfarelli, Stephanie Vie

Faculty Scholarship and Creative Works

This article explores the design and instructional effectiveness of Medulla, an educational game meant to teach brain structure and function to undergraduate psychology students. Developed in the retro-style platformer genre, Medulla uses two-dimensional gameplay with pixel-based graphics to engage students in learning content related to the brain, information which is often pre-requisite to more rigorous psychological study. A pretest posttest design was used in an experiment assessing Medulla’s ability to teach psychology content. Results indicated content knowledge was significantly higher on the posttest than the pretest, with a large effect size. Medulla appears to be an effective learning tool. These …

Love Is A Battlefield: Experience Of Love In Relation To Depression, Laura Hill, Cherisse Flanagan

Modern Psychological Studies

Depression is a debilitating mental illness that entails much more than just sadness. In an attempt to discover if there is a relationship between experience of love and depression, a survey was created to assess these variables. The survey included the Experience of Love Questionnaire (ELQ), an author-developed scale, and the Center for Epidemiological Studies Depression scale (Radloffi 1977). The ELQ consisted of three subscales measuring experience of love in family, friends, and romantic relationships. The hypothesis of this study was that there would be a negative correlation between experience of love and depression. The survey was completed by 103 …

Microexpression Detection In Undergraduate Students, Cameron R. Howell, Rebecca E. Hughes

Modern Psychological Studies

Microexpressions, facial expressions lasting for less than half a second, are a common but unnoticed occurrence. The accuracy of microexpression detection, and college major choice, have both been linked with personality. This led to the hypothesis that different majors should have different levels of accuracy in detection. A convenience sample of 121 undergraduate students, of different majors, was given a short survey about microexpression detection. 10 frontal headshots, portraying examples of 7 different microexpressions, were shown on a screen. Participants were asked to identO, the expressions by choosing from a provided list on the survey. There was no statistical significance …

Auditory Startle Response Predicts Introversion: An Individual Analysis, Kirby M. Jaeger, Austin H. Cox, David Philip Arthur Craig, James W. Grice

Modern Psychological Studies

We assessed a possible link between the Introversion/Extraversion spectrum and sensori-motor gating and predicted self-reported introverts would have more sensitive sensori-motor gating pathways than extraverts at the individual subject level. 28 subjects self-identified as introverts or extraverts; individuals that self-identified as both introverted and extraverted were classified as "ambiverts". Participants'orbicularis oculus muscles were electromyographically measured while abrupt auditory stimuli ranging from 50 to 100 decibels were played over headphones. As predicted, introverts exhibited greater electromyographical frequencies and magnitudes of response to stimuli at almost all levels of stimulus intensity. These results indicate introverts tend to be more sensitive, on a …

Nondysphoric Depressive Symptoms And Cognitive Abilities In Healthy Older Adults, Clint H. Norseth

Loma Linda University Electronic Theses, Dissertations & Projects

Research has shown that depression is associated with poorer cognitive performance and cognitive decline. Cognitive functions such as processing speed, language ability, memory, and executive functions have been found to be affected in older adults with depression. However, there is limited research focused on the effects of minimal or mild depressive symptoms in older adults who do not meet criteria for a depressive disorder. Older adults are more likely than any other population to endorse depressive symptoms in the absence of typical dysphoric symptoms that would qualify an individual for a depressive disorder. Understanding the effects of nondysphoric depressive symptoms …

Prostate Cancer Screening Intention Among Black Men: A Multivariate Analysis, Crystal Renee Clarke

Loma Linda University Electronic Theses, Dissertations & Projects

Prostate cancer is one of the leading causes of death among Black men, and widespread lack of screening contributes to the mortality burden. The purpose of this present study was to evaluate the effect of relationship intimacy with individual intent to screen using the digital rectal examination (DRE) among Black men. The human ecological theory of human development was a good fit for this present study, as individual health status and population health disparities are embedded in larger historical, geographic, socio-cultural, economic, and political contexts. The ecological framework allows researchers to attempt to identify the influences of all these factors. …

Indicators Of Ambiguous Loss In Families With Traumatic Brain Injured Members, Mynda Ohs

Loma Linda University Electronic Theses, Dissertations & Projects

People who have encountered medical traumas can experience significant changes in their lives. As a result, the family members become caregivers and experience increased stress and ambiguous losses (AL). These losses are often unacknowledged even by the family and cause significant distress. It is important that the family acknowledge these losses and allow themselves time to grieve and adapt to the changes in their lives. While it is widely known that caregivers experience this stress, and programs exist to help support these families, there is less known about the effectiveness of these programs. This study has been designed to explore …

Do Parents Favor Their Adoptive Or Biological Children? Predictions From Kin Selection And Compensatory Models, Nancy L. Segal, Norman P. Li, Jamie L. Graham, Steven A. Miller

Research Collection School of Social Sciences

Evolutionary reasoning (Kin Selection Theory) predicts less favorable behaviors directed by parents toward their unrelated children, relative to their biologically related children. By extension, it may be argued that parents should also have less favorable perceptions of the intellectual, personality and other behavioral traits of unrelated children, compared with biologically related children. However, recent work has modified this expectation, given the distinction between unrelated adopted children (who are acquired intentionally) and unrelated stepchildren (who are acquired via mating effort). The compensatory model takes into account evolved desires for parenting and the evolutionarily novel availability of unrelated children. It predicts that …

Cultural Conceptualizations Of The Trauma Response: The Role Of Locus Of Control, Religiosity, And Religious Coping, Yu-Feng Emily Hu

Dissertations

Posttraumatic stress disorder (PTSD) is a relatively recent diagnosis that results in significant personal and societal costs. Given the diversity of American mental health consumers, a more thorough understanding of PTSD and its relation to cultural factors may have important implications for treatment implementation and refinement. Cultural factors such as locus of control, religiosity, and religious coping have been frequently overlooked in trauma research, yet show a clear link to PTSD risk and symptomatology. This study examined these cultural factors in more detail with relation to race and trauma type and their combined influence on PTSD symptomatology. A national sample …

Mental Health Screening Of Veterans Diagnosed With Cancer: Analyzing Psychological Distress And Attitudes Towards Seeking Professional Psychological Help, Jessica Jean Baptiste

Seton Hall University Dissertations and Theses (ETDs)

Studies analyzing mental health care utilization in veterans with a co-occurrence of a medical and psychological diagnosis are still underrepresented in the literature. The primary purpose of this study is to examine psychological screening methods of veterans diagnosed with cancer and determining when these veterans are more likely to endorse psychological symptoms. This information can contribute to the discussion of effective ways of integrating mental health screening in specialty care settings. A correlational, causal-comparative research design is employed to answer the study research questions and hypotheses. The participants include Vietnam, Korean, and World War II veterans seeking oncology services at …

A Person-Centered Examination Of Latino Youth Depressive Symptom Trajectories: The Role Of Youth, Parent, And Dyadic Familism, Jessica Annabel Arizaga

College of Science and Health Theses and Dissertations

A growing body of literature indicates Latino youth are at greater risk for depression relative to other racial/ethnic groups (CDC, 2014). Research examining predictors of Latino youth depression suggests higher familial values might buffer against youth depressive symptoms (Polo & Lopez, 2009; Zeiders et al., 2013b). However, longitudinal relationships between these variables remain largely unexamined. Furthermore, the literature on longitudinal youth depressive symptoms is mixed, with both increases and decreases being observed over time using group-centered analyses. The present study has three major aims: 1) map the trajectories of depressive symptomology among middle-school age Latino youth over the course of …

Onset Patterns Of Chronic Fatigue Syndrome And Myalgic Encephalomyelitis: A Mixed Method Approach, Meredyth Evans

College of Science and Health Theses and Dissertations

Chronic fatigue syndrome (CFS), Myalgic Encephalomyelitis (ME) and Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS) refer to a debilitating illness without a universally accepted or well-understood etiology. Some experts have suggested that there are multiple pathways to the development of ME and CFS, which may also indicate multiple onset patterns. Due to unanswered questions regarding etiology, the onset of ME and CFS is considered a key area of inquiry.

Case criteria for ME and CFS and much of the academic literature suggest that patients typically experience one of two possible onset patterns: sudden or gradual. Many experts consider the mode of ME …

The Role Of Gender Identityand Stereotype Awareness On Sexual Negotiations Strategies For Women, Or'shaundra Tre'nay Benson

College of Science and Health Theses and Dissertations

The consequences of unsafe heterosexual sexual behaviors including unplanned pregnancies and sexually transmitted infections continue to create significant public health problems in the United States. Although research has demonstrated that young adults in general have higher rates of sexually transmitted infections compared to other age groups, young women are especially vulnerable to the ill-effects of unsafe sexual practices, as they must contend with the physicality of an unplanned pregnancy and larger incidences of asymptotic infection transmissions. However, missing from the research and discourse regarding what specific factors may be contributing to high rates of risky behaviors in heterosexual women is …

Visual Hallucinations Differential Diagnosis Annotated Decision Tree, Shelly D. Davis

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Differential diagnosis of the etiology of visual hallucinations is challenging. Although visual hallucinations can be symptomatic of psychiatric disorder, they more commonly indicate neurological or medical disorders, sensory impairment, or substance intoxication or withdrawal. Accurate diagnosis and treatment is crucial given that misdiagnosis and incorrect treatment intervention can have profound consequences. The purpose of this paper is to summarize the most prevalent causes of visual hallucinations, review the DSM-5 hallucination decision tree, and provide an annotated visual hallucination differential diagnosis decision tree.

Examining The Relationship Between Bicultural Stress, Mental Well-Being, Perceived Social Support, And Education Among People Of African Descent, Zemed Beraki Berhe

Seton Hall University Dissertations and Theses (ETDs)

Studies investigating the bicultural experiences of people of African descent are significantly underrepresented in the literature. The primary purpose of this exploratory study was to examine the relationship between experiences of bicultural stress and mental well-being. In investigating this relationship, perceived social support and education were examined as protective factors, and its relationship to bicultural stress for this population. With the ultimate goal of this information contributing to the understanding of bicultural processes within this population and the relationship to mental health outcomes. A non-experimental (non-randomized) research design was utilized to examine the study research questions and hypotheses. The participants …

Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga

Arts & Sciences Graduate Student Theses and Dissertations

Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions. Methods: Children with PKU (n = 31, mean age = 12.2 years) were …

Breaking Apart The Reinforcement Learning Deficit In Schizophrenia, Adam Culbreth

Arts & Sciences Graduate Student Theses and Dissertations

Reinforcement learning deficits have long been associated with schizophrenia. However, tasks traditionally used to assess these deficits often rely on multiple processing streams leaving the etiology of these task deficits unclear. In the current study, we borrowed a recent framework from computational neuroscience, which separates reinforcement-learning into two distinct systems, model-based and model-free. Under this framework, the model-free system learns about the value of actions in the immediate context, while the model-based system learns about the value of actions in both immediate and subsequent states that may be encountered as a result of their actions. Using a decision task that …

Manipulation Of Negative Social Evaluative Fears On Body Dissatisfaction And Eating Behaviors: Does Fear Of Social Evaluation Lead To Disordered Eating?, Cheri A. Levinson

Arts & Sciences Graduate Student Theses and Dissertations

Social anxiety and eating disorders are highly comorbid. Researchers have suggested that there may be shared vulnerabilities that underlie the development of these disorders. Two of these proposed vulnerabilities are fear of negative evaluation and social appearance anxiety (i.e., fear of negative evaluation specifically focused on one’s appearance). Regarding disordered eating, previous self-report research has found that social appearance anxiety may be especially relevant for body dissatisfaction, whereas fear of negative evaluation may be relevant for drive for thinness. In the current study I manipulated fear of negative evaluation and social appearance anxiety using a speech task in 160 undergraduate …

Relationship Between Serum Biomarkers And Three-Month Outcomes Following Pediatric Traumatic Brain Injury (Tbi), Alicia Leanne Janos

Arts & Sciences Graduate Student Theses and Dissertations

With more than 475,000 cases annually, traumatic brain injury (TBI) is the leading cause of morbidity and mortality in children. Promising new tools for the prediction of functional outcomes following pediatric TBI are biomarkers of brain injury that can be detected in blood serum. The most commonly studied biomarkers, S100β, neuron-specific enolase (NSE), and myelin basic protein (MBP), have myriad limitations which preclude their use in clinical care. In the present study, serum concentrations of two novel biomarkers of brain injury (i.e., ubiquitin carboxy-terminal hydrolase-L1, UCH-L1; glial fibrillary acidic protein, GFAP) were collected 24 hours following severe TBI in 30 …

Social Networking Website Use And Eating Pathology: Relations, Moderators, And Motivation To Improve, Michelle S. St. Paul

Arts & Sciences Graduate Student Theses and Dissertations

Social networking website (SNW) use has been found to be associated with decreased body image or esteem and increased eating disorder (ED) symptoms. In turn, SNW use may also be associated with decreased motivation to improve body image (BI) and reduced self-efficacy in one’s ability to do so. However, the impact of SNW use on motivation or self-efficacy to improve BI has not yet been studied. Also, particular moderators of the relationships between SNW and eating pathology have not yet been evaluated. This study aimed to: 1) replicate past literature by examining the relation between SNW use and eating pathology, …
