Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis

Master's Theses

Anxiety disorders are the most prevalent class of mental disorders, often characterized by a chronic course and comorbid psychopathology. The anxiety-stress literature utilizing cortisol as a biomarker of the hypothalamus pituitary adrenal (HPA) axis has been inconsistent. The establishment of salivary alpha-amylase (sAA) as a biomarker of sympathetic nervous system (SNS) activation allows researchers an opportunity to examine the stress response more fully. This study sought to explore relationships between trait anxiety and salivary stress biomarkers in an outpatient sample attending a specialized anxiety treatment center. Multiple regression and moderator analyses were conducted to examine associations between psychosocial and physiological …

Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé

Department of Psychology Faculty Scholarship and Creative Works

We review literature examining relationships between tympanic membrane temperature (TMT), affective/motivational orientation, and hemispheric activity. Lateralized differences in TMT might enable real-time monitoring of hemispheric activity in real-world conditions, and could serve as a corroborating marker of mental illnesses associated with specific affective dysregulation. We support the proposal that TMT holds potential for broadly indexing lateralized brain physiology during tasks demanding the processing and representation of emotional and/or motivational states, and for predicting trait-related affective/motivational orientations. The precise nature of the relationship between TMT and brain physiology, however, remains elusive. Indeed the limited extant research has sampled different participant populations …

Traumatic Brain Injury: The Relationship Of Psychosocial Variables And Location Of Injury To Post-Injury Depression, Alicia L. Smith

Theses, Dissertations and Capstones

Traumatic Brain Injury (TBI) affects nearly 1.4 million people in the United States annually, and of these, 10% to 77% will experience post-injury depression. Psychosocial variables such as previous substance and alcohol abuse, prior mental illness, low educational attainment, and poverty have been identified as possible risk factors. Additionally, the location of injury appears to play a key role particularly if the injury occurs in the left hemisphere. This study examined archival data from brain-injured patients in an effort to better understand the factors related to post-TBI depression. Past medical records of brain-injured adults (N = 52) were reviewed …

The Role Of Pubertal Timing And Temperamental Vulnerability In Adolescents’ Internalizing Symptoms, Lisa J. Crockett, Gustavo Carlo, Jennifer M. Wolff, Meredith O. Hope

Department of Psychology: Faculty Publications

This longitudinal study examined the joint role of pubertal timing and temperament variables (emotional reactivity and self-regulation) in predicting adolescents’ internalizing symptoms. The multiethnic sample included 1,025 adolescent girls and boys followed fromage 11 to age 15 (Mage¼11.03 years at Time 1). In structural equation models, age 11 measures of pubertal timing, emotional reactivity, and self-regulation and their interactions were used to predict adolescents’ internalizing behavior concurrently and at age 15. Results indicated that, among girls, early pubertal timing, higher emotional reactivity, and lower self-regulation predicted increased internalizing behavior. In addition, self-regulation moderated the effect of pubertal timing such that …

Short Communication: Powerless And Jobless? Comparing The Effects Of Powerless Speech And Speech Disorders On An Applicant’S Employability, Christian M. End, Katherine Saunders

Faculty Scholarship

The present study examines the impact of a speech disorder (a lateral lisp) and powerless speech on an applicant’s hireability. College students (N = 113) reviewed an applicant’s resume, as well as a description of two occupations/job openings that varied in regard to necessitating speech. Participants listened to one of three interviews (speech disorder vs. powerless speech vs. control), indicated their willingness to hire the applicant, and then completed hire-ability and employability scales for both positions, as well as an impressions ratings form. Contrary to the hypotheses, few differences between the “employers” responses to the control and speech disorder applicants …

Functional Outcomes In A Postacute Brain Injury Rehabilitation Program, Esther Brahmstadt

PCOM Psychology Dissertations

The purpose of this study was to evaluate functional outcomes among individuals with acquired brain injury who received treatment at a postacute brain injury rehabilitation program over a 3-year period (2008 to 2010). Participation in community and/or social roles, supervision required, and adaptive functioning outcomes were evaluated in a sample of 109 adults (71% male, 29% female; 88.1% White, 11.9% non-White; 67.9% injured at 18 years of age or older, 32.1% injured at under 18 years of age). Contrary to the hypotheses, there was a statistically significant increase in adaptive functioning and supervision required scores, suggesting increasing impairment over time. …

Pain Tolerance And Thresholds In Women With Dyspareunia: Do Pain And Sex Primes Have Differential Effects?, Lea Thaler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dyspareunia, defined as recurrent pain in the genital/pelvic region during sexual intercourse, is one of the most common types of female sexual dysfunction, affecting approximately 15% of women between the ages of 18 and 24. Women with dyspareunia display similar cognitive and emotional styles evidenced in other chronic pain conditions (e.g. hypervigilance for pain information, catastrophization, and negative affect); however, dyspareunia is a unique pain disorder in that it directly involves sexual functioning. This pairing of pain and sex raises the issue of conditioning. Is it possible that because intercourse is painful for women with dyspareunia, the presentation of any …

Psychology and Child Development

To understand the relationship between BMI and sleep patterns in Cal Poly Freshman (First years) over the course of their first year at Cal Poly. First year students were recruited via campus email to fill out a survey regarding various health aspects. The survey was filled out at the beginning of the year (Fall 2009), and again in June (Spring 2010). The questions used in this study only pertained to height, weight, sleep quantity, and sleep quantity satisfaction rating. The results were not significant for the cross sectional analysis of the Fall 2009 sample and the Spring 2010 sample. The …

Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy

Dissertations

Research has shown that acute drug administration may affect impulsivity (i.e., choice for small, immediate rewards over large, delayed rewards) on laboratory delay-discounting tasks. Few studies have investigated how drug abstinence affects impulsivity. Investigating how drug abstinence affects impulsivity may be relevant to preventing relapse. Two previous studies have investigated the effects of short-term nicotine abstinence on impulsivity using delay-discounting tasks. The results were mixed, one study suggested that choices became more impulsive (i.e., delayed money was devalued) under nicotine deprivation. One goal of the present research was to further investigate how nicotine deprivation affects delay-discounting for money rewards. In …

A Combined Fmri And Dti Examination Of Functional Language Lateralization And Arcuate Fasciculus Structure: Effects Of Degree Versus Direction Of Hand Preference Author Links Open Overlay Panel, Ruth E. Propper, Lauren J. O'Donnell, Stephen Whalen, Yanmei Tie, Isaiah Norton, Ralph O. Suarez, Lilla Zollei, Alireza Radmanesh, Alexandra Golby

Department of Psychology Faculty Scholarship and Creative Works

The present study examined the relationship between hand preference degree and direction, functional language lateralization in Broca’s and Wernicke’s areas, and structural measures of the arcuate fasciculus. Results revealed an effect of degree of hand preference on arcuate fasciculus structure, such that consistently-handed individuals, regardless of the direction of hand preference, demonstrated the most asymmetric arcuate fasciculus, with larger left versus right arcuate, as measured by DTI. Functional language lateralization in Wernicke’s area, measured via fMRI, was related to arcuate fasciculus volume in consistent-left-handers only, and only in people who were not right hemisphere lateralized for language; given the …

Immune Function And Health Outcomes In Women With Depression, Cherie Howk, Mary P. Bennett

Nursing Faculty Publications

This research reports immune function and health outcomes in women with depression, as compared with a nondepressed control group. Using Psychoneuroimmunolgy theory and a descriptive comparison design, scores on the Beck Depression Inventory (BDI) were used to divide 40 non-hospitalized Caucasian women between the ages of 18 and 65 years into either the control or depression comparison group. Women with depression were found to report significantly more incidences of illness over the previous two months and they were found to have significantly more indicators of illness at the time of the exam as compared to the controls. However, contrary to …

Smoking And Psychological Health In Relation To Country Of Origin, Michael Lyvers, Tessa Hall, Mark Bahr

Mike Lyvers

In English-speaking, Western-Anglo countries, where smoking has become stigmatized in recent decades as a result of widespread anti-smoking campaigns, smokers commonly report poorer psychological health on average than non-smokers do. This may be indirectly related to the strong pressures to quit in such countries, as poorer psychological health is associated with a reduced likelihood of quitting, thus leading to a selection bias for smokers with relatively poorer psychological health. In the present study, 147 smoker and non-smoker participants either came from Western-Anglo countries where smoking has become stigmatized (Australia, Canada, U.S.) or countries in regions where smoking remains relatively more …

Attachment: The Antidote To Trauma, Joshua Straub

Faculty Publications and Presentations

Trauma and loss in life are inevitable. And all too often the traumatic experience itself can be enough to paralyze the mental, emotional, and spiritual state of any given person. Unable to interpret the traumatic experience, many instead are left defined by it. Helping clients discern the objective experience and their subjective reactions to it will help free them from the emotions and beliefs that subsequently control their lives. Based on the most relevant attachment theory research and clinical techniques, this workshop teaches the attentional strategies necessary to helping clients overcome trauma.

Beer Goggles: Blood Alcohol Concentration In Relation To Attractiveness Ratings For Unfamiliar Opposite Sex Faces In Naturalistic Settings, Michael Lyvers, E. Cholakians, M. Puorro, S. Sundram

Mike Lyvers

The popular notion that alcohol intoxication enhances perceptions of the physical attractiveness of the opposite sex has been inconsistently supported. The current study tested intoxicated and non-intoxicated persons of both genders in naturalistic settings after measuring their blood alcohol concentration (BAC) by a breath test. A sample of 80 heterosexual university student social drinkers was recruited at a campus pub and campus parties over a 3-month period to take a survey rating the attractiveness of unfamiliar faces of the opposite gender presented in photographs. Attractiveness ratings were positively correlated with BAC. Analysis of covariance (ANCOVA) was conducted on attractiveness ratings …

Psychological Distress And Change In A Pediatric Obesity Population, Amy Rebecca Beck

Loma Linda University Electronic Theses, Dissertations & Projects

Pediatric overweight and obesity is a growing national epidemic with 15 percent of children ages 6-19 considered obese and at least 22 percent considered overweight. While there is considerable research pointing to contributing factors of obesity, there is a paucity of research which elucidates what contributes to successful intervention. Considering that by the year 2050, nearly 50 million Americans may be obese, understanding the factors delineating success of weight loss and prevention is a necessity. The purpose of this study was to utilize archival data from the LLU Growing Fit Program to evaluate the levels of psychological distress experienced by …

Eating Disorders: A Study Of University Type And Prevalence, Emily C. Riggins

Senior Honors Theses

Disordered eating has become an increasing problem, especially in western culture. A study was conducted to determine a possible relationship between disordered eating among college students and type of university. Previous studies allude to the possibility of private evangelical colleges yielding more eating disorders than private non-evangelical and public colleges. College students at two east coast universities were compared on the Eating Attitudes Test and a demographic questionnaire. The research indicated that prevalence of eating disorders is not significantly different between private evangelical institutions and private non-evangelical institutions. The findings show some background, prevalence, causes, and theoretical explanation of eating …

A project description, including the scholarship of teaching and learning, and an overview of its outcomes are presented. The project goal was accomplished; students positively evaluated learning outcomes and displayed a significant increase in knowledge about older adults and aging. Implications for college instructors are discussed. (Contains …

A Model For Preventing Anorexia In College Students, Laura Ann Negin

Loma Linda University Electronic Theses, Dissertations & Projects

The prevalence of anorexia nervosa in the general population is relatively low, but anorexia is at the forefront of health concerns because of its seriousness. Unhealthy weight loss has numerous physical, psychological, and social consequences. Most seriously, the mortality rate for people with eating disorders is the highest of all the major psychiatric disorders.

This dissertation presents a model for preventing anorexia nervosa in a population of college students that includes a comprehensive institutional approach, psychoeducational software, a high-risk population, a holistic approach that identifies an individual’s personal risk factors and protective factors, and individual therapy.

The model is built …

A Biopsychosocial Perspective Of Gulf War Illness: A Structural Model, Katherine N. Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Veterans deployed during the Persian Gulf War in 1990-1991 report significantly more nonspecific symptoms and poorer health than their nondeployed peers. This amalgamation of chronic, multisymptom health complaints is commonly referred to as Gulf War Illness. There are two major theoretical models within the medical/health field that may help explain these symptoms: 1) the traditional biomedical model, and 2) the more recently evolved (late 1970’s) biopsychosocial model. Theorists have proposed two major causal pathways in studying the etiology of health complaints of Gulf War veterans, the physical pathway and the psychosocial pathway. In the present study, the biopsychosocial model was …

The Biological Etiology Of Mental Health Disorders: Social Influences And Change Potential Of Practitioners’ Beliefs, Donna Marie Midkiff

Theses, Dissertations and Capstones

This study was designed to examine mental health professionals’ strength of belief in biological causation of several syndromes including ADHD, unipolar depression, anxiety disorders, and schizophrenia and whether a three-hour educational program will alter their thinking. Findings suggest that pre-training, mental health professionals’ reported strength of belief regarding the etiology of many mental health disorders tends toward the biologically based. Also, this study demonstrated that attendance at a three hour training program is able to reduce the expressed acceptance of biological causation of such disorders. The social influences of pharmaceutical direct to consumer advertising and medical guild dominance, as well …

Self-Management Strategies Mediate Self-Efficacy And Physical Activity, Amanda Birnbaum, Rod K. Dishman, Robert W. Motl, James F. Sallis, Andrea L. Dunn, Greg J. Welk, Ariane L. Yung, Carolyn C. Voorhees, Jared B. Jobe

Department of Public Health Scholarship and Creative Works

Self-efficacy theory proposes that girls who have confidence in their capability to be physically active will perceive fewer barriers to physical activity or be less influenced by them, be more likely to pursue perceived benefits of being physically active, and be more likely to enjoy physical activity. Self-efficacy is theorized also to influence physical activity through self-management strategies (e.g., thoughts, goals, plans, and acts) that support physical activity, but this idea has not been empirically tested.

Why Girls? The Importance Of Developing Gender-Specific Health Promotion Programs For Adolescent Girls, Amanda Birnbaum, Tracy R. Nichols

Department of Public Health Scholarship and Creative Works

Adolescence is a time when many girls begin to develop unhealthy behaviors that can affect myriad short- and long-term health outcomes across their lifespan.2There is evidence that smoking, physical activity, and diet are habituated during adolescence, and some physiologic processes of adolescence, such as peak bone mass development, have direct effects on future health.3-4 Establishing healthy practices, beliefs and knowledge among adolescent girls will decrease morbidity and mortality among adult women and potentially affect the health of men and children through women’s role as healthcare agents. This paper provides a brief review of lifestyle health behaviors among women and girls …

Psychosocial Correlates Of Physical Activity And Sedentary Leisure Habits In Young Adolescents: The Teens Eating For Energy And Nutrition At School Study, Amanda Birnbaum, Kathryn H. Schmitz, Leslie Lytle, Glenn A. Phillips, David M. Murray, Martha Y. Kubik

Department of Public Health Scholarship and Creative Works

BACKGROUND: Low levels of physical activity (PA) and highly sedentary leisure habits (SLH) in youth may establish behavioral patterns that will predispose youth to increased chronic disease risk in adulthood. The purpose of this paper was to examine associations of demographic and psychosocial factors with self-reported PA and SLH in young adolescents. METHODS: A general linear mixed model predicted self-reported PA and SLH in the spring from demographic and psychosocial variables measured the previous fall in 3798 seventh grade students. RESULTS: PA and SLH differed by race, with Caucasian students reporting among the highest PA and lowest SLH. Perceptions of …

Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman

Department of Psychology Faculty Scholarship and Creative Works

The dependence of episodic memories on interhemispheric processing was tested. In Experiment 1, positive familial sinistrality (FS+; e.g., the presence of left-handed relatives) was associated with superior episodic memory and inferior implicit memory in comparison with negative familial sinistrality (i.e., FS-). This reflected a greater degree of interhemispheric interaction in FS+ participants, which was hypothesized as facilitating episodic memory. In Experiment 2, the authors directly manipulated inter- versus intrahemispheric processing using tests of episodic (recognition) and semantic (lexical decision) memory in which letter strings were presented twice within trial blocks. Semantic memory was superior when the 2nd presentation went to …
