The Role Of Engagement Across Conceptually Distinct Treatment Elements For Social Anxiety Disorder, Timothy M. Emge

Department of Psychology: Dissertations, Theses, and Student Research

There are currently several efficacious treatments for social anxiety disorder (e.g. exposure therapy and cognitive therapy). Each of these treatments is thought to reduce symptoms of social anxiety by disrupting maintenance mechanisms of the disorder, yet mechanism of change research has not supported this view. The current study compared components from each therapy modality in order to better understand why symptoms reduce similarly between conceptually distinct treatments. Participants with high social anxiety were randomly assigned to give a speech with cognitive restructuring and engagement-enhancing procedures, cognitive preparation and video feedback, or a speech alone. Self-ratings of speech performance, confidence in …

Dimensions Of Individuals' Judgements About Sexual Attraction, Romantic Attachment, And Sexual Orientation, Luis F. Morales Knight

Department of Psychology: Dissertations, Theses, and Student Research

Despite 150 years of scientific interest in sexual orientation, contemporary investigators grapple with a number of serious difficulties. A precise, unified definition of sexual orientation appropriate for scientific use continues to elude researchers, most likely because there is still no single coherent theory of sexual orientation. This lack impedes research into the measurement of sexual orientation. Existing measurements of sexual orientation rely on partial or incompletely empirical research. The present study identified promising avenues for development of credible definitions, theories, and measurements of sexual orientation: (a) mate-selection tasks; (b) the idea that bisexually-identified individuals place a lower priority on partner …

Stress, Coping And Suicide Ideation In Chinese College Students, Xiaoyun Zhang, Haiping Wang, Yan Ruth Xia, Xiaohong Liu, Eunju Jung

Department of Child, Youth, and Family Studies: Faculty Publications

The study was to examine 1) whether stress and coping styles could significantly predict the probability of suicide ideation; 2) and whether coping styles were mediators or moderators on the association between life stress and suicide ideation. The survey was conducted in a sample of 671 Chinese college students. Approximately twenty percent students reported having suicide ideation. Life stress, active coping styles, and passive coping styles all had independent effect on the probability of suicide ideation. Passive coping styles, especially fantasizing, mediated the relation between life stress and suicide ideation. Moderation hypotheses were not supported. Implications of the findings and …

Narrative Health Communication And Behavior Change: The Influence Of Exemplars In The News On Intention To Quit Smoking., Hyun Suk Kim, Cabral A. Bigman, Amy E. Leader, Caryn Lerman, Joseph N. Cappella

Department of Medical Oncology Faculty Papers

This study investigated psychological mechanisms underlying the effect of narrative health communication on behavioral intention. Specifically, the study examined how exemplification in news about successful smoking cessation affects recipients' narrative engagement, thereby changing their intention to quit smoking. Nationally representative samples of U.S. adult smokers participated in 2 experiments. The results from the 2 experiments consistently showed that smokers reading a news article with an exemplar experienced greater narrative engagement compared to those reading an article without an exemplar. Those who reported more engagement were in turn more likely to report greater smoking cessation intentions.

Research Brief: "Employment Outcomes And Ptsd Symptom Severity", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This study investigates how the severity of PTSD symptoms relates to employment and earnings. It found that veterans with more severe symptoms of PTSD were more likely to work part-time or not at all rather than have full-time work. In practice, treating PTSD, even if some symptoms remain, could result in better employment outcomes for veterans. In policy, policymakers should consider providing previously successful programs focused on veterans with PTSD for individuals with other mental health conditions. Suggestions for future research include a large, controlled, longitudinal survey that would allow researchers to investigate more thoroughly how PTSD symptoms relate to …

Posttraumatic Stress And Myocardial Infarction Risk Perceptions In Hospitalized Acute Coronary Syndrome Patients, Donald Edmondson, Jonathan A. Shaffer, Ellen-Ge Denton, Daichi Shimbo, Lynn Clemow

Publications and Research

Posttraumatic stress disorder (PTSD) is related to acute coronary syndrome (ACS; i.e., myocardial infarction or unstable angina) recurrence and poor post-ACS adherence to medical advice. Since risk perceptions are a primary motivator of adherence behaviors, we assessed the relationship of probable PTSD to ACS risk perceptions in hospitalized ACS patients (n = 420). Participants completed a brief PTSD screen 3-7 days post-ACS, and rated their 1-year ACS recurrence risk relative to other men or women their age. Most participants exhibited optimistic bias (mean recurrence risk estimate between "average" and "below average"). Further, participants who screened positive for current PTSD (n …

Linguistic Devices, Emotionality, And Memorability Of Computer Mediated Communication, Angela M. Mion

Undergraduate Honors Thesis Collection

I examined whether college students use shortcuts, pragmatics, and errors in text messages differently depending on their gender and the emotionality of the message. Results indicate that the prevalence of particular shortcuts differed across happy, sad, and angry messages, but gender did not influence use of linguistic devices. In a second study, I examined the emotionality and memorability of text messages versus voicemails. Results indicate that texts may be remembered better than voicemails, and happy, sad, and angry messages may be remembered differently by men and women.

Predictors Of Depression For Low-Income African American Single Mothers, Jennifer Hatcher, Mary K. Rayens, Ann R. Peden, Lynne A. Hall

Journal of Health Disparities Research and Practice

Methods: Cross sectional secondary data analysis of a study of low-income African American single mothers with children ages 2-6. Path analysis was used to test a model of the potential mediating role of negative thinking. It was hypothesized that negative thinking mediates the effects of chronic stressors, general health status, and self-esteem on depressive symptoms

Finding: Negative thinking mediated the relationships of chronic stressors and self-esteem …

Recruitment Of African Americans For Obsessive Compulsive Disorder Treatment Research, Georgia Michalopoulou, Pamela Falzarano, David Rosenberg

Journal of Health Disparities Research and Practice

A systematic review of recruitment approaches was conducted as a step towards creating a culturally sensitive approach to enhance participation of African Americans into our Obsessive Compulsive Disorder (OCD) treatment research. From this review, a recruitment plan providing a collaborative partnership between the African American community and the clinical investigators was adopted. We sought to increase participation in OCD research by developing culturally sensitive educational materials, implementing strategies such as recruiter ethnic match, encouraging individuals to participate by a pastor, and providing education in the community that attempted to decrease stigmatization of mental illness and target cultural suspicion of institutional …

Random Inter Stimulus Interval Increases Signal-To-Noise Ratio., Juliane Armstrong

Undergraduate Honors Theses

Incremental improvements are continuously being made to P300-Speller BCI paradigms. Accurate classification depends on a high signal-to-noise ratio (SNR) between the target and nontarget items. Fixed presentation rates produce a large flash-evoked response that persists throughout the recording epoch, which can potentially undermine the classification of P300-responses. By introducing a random interstimulus interval (ISI) to a previously improved P300-Speller paradigm (i.e., Checkerboard Paradigm; CBP) we expect to reduce the deleterious flash-evoked responses and increase the P300 classification SNR. Data were recorded from 32 EEG locations (right mastoid referenced) from 13 subjects using the CBP with two conditions. In the Random …

Baseline Serum Prolactin In Drug-Naive, Firstepisode Schizophrenia And Outcome At Five Years: Is It A Predictive Factor?, Amresh Srivastava, Megan Johnston, Yves Bureau, Nilesh Shah

Depression And Evangelical Christian Spirituality: Exploring A Theoretical Model, Katheryn Jane Klukow

Masters Theses and Doctoral Dissertations

While religious involvement, particularly intrinsic religiosity or spirituality, has shown a significant inverse relationship with depression, this relationship is complex and multifaceted and several decades of study have yet to reveal a clear pattern. This work is a survey of the current research on the etiology and symptomology of depression and its interaction with spirituality. This work is testing a new model that views the effects of depression on spirituality as a function of an individual’s perceived relationship with God. A survey was distributed to a sample of 135 evangelical Christians. Depressed persons made up approximately 16% of the sample. …

Comparison Of Sport Competitive Anxiety Levels Of Saudi Arabian National Team Athletes With And Without Disabilities In Competitions, Hassan Ahmad Halawani

Graduate Theses and Dissertations

Anxiety in sport is complex and can lead to a number of undesirable consequences such as burnout, performance difficulties, interpersonal problems, and injury. The purpose of this study was to compare whether significant differences existed in the levels of somatic anxiety, worry, and concentration disruption between individuals of the Saudi Arabian national team with and without disabilities in competitions. In addition, differences in somatic anxiety, worry, and concentration disruption were examined between athletes in an individual or team sport. The Sport Anxiety Sale (SAS-2, Smith et. al, 2006) was employed to measure the subscales of somatic anxiety, worry, and consternation …

A Study Of The Link Between Partial Sleep Deprivation And Obesity, Jennifer Pacheco

Honors College Theses

Obesity has become a major health problem with increasing prevalence and is related to multiple medical consequences, such as increased risk for diabetes, heart disease, arthritis, and cancer (Hasler et al., 2004). Due to the limited availability of effective treatment of weight problems, it is necessary to identify potential risk factors for obesity. One factor that has received increased attention is chronic partial sleep deprivation (<7 hours of sleep a night). The decrease in average sleep duration over the past three to four decades has occurred simultaneously with the increase in the prevalence of obesity. Chronic partial sleep deprivation could be a possible risk factor for obesity, but current understanding of the processes linking sleep deprivation to obesity is incomplete. The research will focus on examining the possible pathways through which partial sleep deprivation contributes to the development of obesity: alterations in metabolic pathways and waking behavior, including eating behavior and physical inactivity. The hypothesis behind the proposed study is that increasing sleep duration in obese individuals who experience partial sleep deprivation will lead to a decreased BMI. Research addressing the possible pathways and targeting the amount of sleep will benefit individuals in preventing and/or treating obesity.

Descriptive Experience Sampling Interactive Multi-Media Training Tool For Subjunctification And Illustrative Interviews, Stacy Lynne Reger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Modern experience sampling methods attempt to understand the phenomenology of inner experience through a variety of methods, including questionnaires, diaries, and verbalization of ongoing cognitive processes. The goal of such studies is to minimize potential roadblocks to accessing inner experience, such as retrospective recall, memory failures, and bias. The current project focuses on one such method, Descriptive Experience Sampling (DES). DES is an idiographic, exploratory, and ecologically valid method of studying inner experience. In this method, participants wear a beeper with an earphone that emits a random beep. When the beep sounds, the participant is to write down notes about …

Obstacles To Dieting Behavior, Shahram Heshmat

Journal of Food Law & Policy

Despite documented short term success, dieting has a very low success rates, most dieters regain their weight back within 3-5 years. The question is why do people fail to stick to their goal for eating a healthy diet in order to lose weight? One possible answer is that people have self-control problems in the form of a present-biased preference. From a prior perspective, they want to behave relatively patiently, but as the moment of action approaches, they want to behave relatively impatiently. The essay presents some insights from behavioral economics to explain why people fail to maintain healthy behavior.

The Stress Coping Skills Of Undergraduate Collegiate Aviators, Jennifer Kirschner, John P. Young, Richard Fanjoy, Donald Petrin

Aviation Technology Graduate Student Publications

An important human factors research interest area is error reduction. Although pilots placed in highly stressful situations have an increased chance of making errors, they use coping skills to lower their stress level and reduce the likelihood of errors. Typically, coping skills are conceptually separated into three types: active coping skills change the situation to make it inherently less stressful, emotion-focused coping skills use discussion or thinking about the situation in a different way to diminish the negative emotional reaction associated with the stressful situation, and avoidant coping skills allow one to mentally and/or physically disengage through the use of …

Using Negative Feedback To Guide Behavior: Impairments On The Wisconsin Card Sorting Test Relates To Psychosis, Sally Barney

UNLV Theses, Dissertations, Professional Papers, and Capstones

There is increasing controversy regarding the distinction between schizophrenia and bipolar disorder as separate diagnostic categories because these disorders share many features in common. These and other findings suggest that bipolar disorder and schizophrenia may be better conceptualized along a continuum or within more homogeneous subsets of affective, psychotic, and mixed symptomatology.

Dopamine dysregulation has been found in schizophrenia and bipolar disorder, particularly those that experience psychosis during the acute phases of their bipolar illness. Dopamine has been found to play a role in reward and reward learning. Recently, research has found that individuals with schizophrenia experience deficits in reward …

The Delivery System Design Of A Community Mental Health Center And Provision Of Quality: Cardiometabolic Screening For Persons With A Severe Mental Illness Prescribed Atypical Antipsychotic Medication, Dawn Marie Vanderhoef

Theses and Dissertations (ETD)

Background: Persons with a severe mental illness (SMI) prematurely lose up to 25 years of life when compared to the general population. This patient population has increased morbidity and mortality due to higher than normal rates of obesity, hypertension, diabetes, and cardiovascular disease. Treatment of SMI often includes the use of atypical antipsychotic (AA) medication which has been associated with the development of cardiometabolic illnesses. In response to the higher rates of co-morbid, chronic physical illness, monitoring guidelines for cardiometabolic illness have been published. Despite these guidelines, screening rates for cardiometabolic illness in this population remain low. Neither community mental …

Evaluating The Sustained Psychological Benefits Of On-Site Employee Health Programs, Stephen Spencer Clancy

Masters Theses and Doctoral Dissertations

The present study was conducted to explore whether employee wellness programs actually promote long term changes in participating employees’ psychological health. Forty four participants were included in the final sample from a large southeastern organization currently offering three different structured wellness programs to its employees. A semi-longitudinal study design was implemented involving three data points over a 5 month time frame. Analyses were conducted to examine factors impacting participation in the programs and the changes those programs have on employees’ perceived levels of stress, psychological well-being, job-satisfaction, and organizational commitment. Results suggest that participation in these programs does result improved …

Love Means Never Having To Say You're Sorry, But What About Malpractice? A Look At Verbal And Nonverbal Factors Affecting Perceptions Of Apologies In A Medical Malpractice Case, Sarah Thimsen

Department of Psychology: Dissertations, Theses, and Student Research

Apologies are part of daily life and occur in a variety of contexts. A large body of literature on the effects of apologies indicated that apologies have a positive effect – those receiving apologies have more positive views of the transgressor (e.g., Bornstein, Rung, & Miller, 2002; Goei, Roberty, Meyer, & Carlyle, 1997; Robbennolt, 2003; Sitkin & Beis, 1993; Takaku, 2000). An area of emerging research in the realm of apologies is in the area of medical malpractice. The research presented here sought to expand on the field of apologies, specifically by examining the effects of an apology in a …

An Investigation Of The Role Of Experiential Avoidance In Posttraumatic Stress Disorder, Meaghan M. Lewis

Honors Theses

Experiential avoidance is a construct that researchers have proposed as a possible mediating factor between psychopathology and a prior history of traumatic events. Among the traumatic events investigated in the research literature, experiential avoidance has demonstrated correlations with prior experiences of sexual victimization. Posttraumatic stress disorder (PTSD) and PTSD symptoms have also been linked with incidence of sexual victimization and engaging in experiential avoidance. Another variable commonly associated with this construct is problematic alcohol consumption. The present study presumed that women with a history of sexual victimization would report high PTSD symptoms, a stronger likelihood of partaking in problem drinking, …

Activity Choice And Extinction Intervention For Escape Maintained Behavior, Ali M. Markowitz

Honors Theses

Tantrums and non-compliant problem behaviors challenge children diagnosed with autism’s progress in early childhood special education classrooms by interfering with the child’s learning opportunities. Autism is a pervasive developmental disorder causing abnormal or impaired development in social interactions and communication (DSM-IV, 1994). This paper looks at a single case on a preschool aged child diagnosed with autism exhibiting tantrums and problem behaviors. These tantrums and non-compliant problem behaviors included kicking, scratching, screaming, hitting, flopping on to the floor or eloping (leaving the table, chair or work area). One study conducted showed that activity choice intervention decreases the occurrence of problem …

Using Tag To Increase Play Skills, Melissa A. Boggs

Honors Theses

TAG (Teaching with Acoustical Guidance) involves using auditory stimuli as a reinforcer for correct behavior or correct components of a behavior chain. Theoretically, TAG is an effective reinforcer because a click (the auditory stimuli) is paired with back up reinforcers (tangible reinforcers and social praise) and consequently becomes a conditioned reinforcer. The current study assesses the effectiveness of TAG in structured playtime activities in a child diagnosed with autism. The behaviors measured include a receptive identification procedure, an imitative drawing procedure and a paperclip drop procedure. Each of these responses required multiple behaviors to be completed with the paperclip drop …

Adolescent Decision Making And Risk Behavior: A Neurobiological Approach, Jennifer M. Wolff

Department of Psychology: Dissertations, Theses, and Student Research

In this study, the neurobiological theory of adolescent decision making and risk taking and the dual-process decision making theory were tested in a sample of college students. Participants responded to questions in a survey about decision making style, socio-emotional processes, cognitive control processes, and deviant peers. The goals of the research were to test the relation between decision making processes (intuitive and deliberative) and risk behaviors, to test the potential overlap between intuitive and deliberative decision making as described in the more traditional dual-process models and the socio-emotional and cognitive control systems of the neurobiological model, and to extend the …

Adjusting For Confounding By Neighborhood Using A Proportional Odds Model And Complex Survey Data, Babette A. Brumback, Amy B. Dailey, Hao W. Zheng

Health Sciences Faculty Publications

In social epidemiology, an individual's neighborhood is considered to be an important determinant of health behaviors, mediators, and outcomes. Consequently, when investigating health disparities, researchers may wish to adjust for confounding by unmeasured neighborhood factors, such as local availability of health facilities or cultural predispositions. With a simple random sample and a binary outcome, a conditional logistic regression analysis that treats individuals within a neighborhood as a matched set is a natural method to use. The authors present a generalization of this method for ordinal outcomes and complex sampling designs. The method is based on a proportional odds model and …

Methamphetamine-Associated Psychosis, Kathleen M. Grant, Tricia D. Le Van, Sandra M. Wells, Ming Li, Scott F. Stoltenberg, Howard E. Gendelman, Gustavo Carlo, Rick A. Bevins

Department of Psychology: Faculty Publications

Methamphetamine (METH) is a frequent drug of abuse in U.S. populations and commonly associated with psychosis. This may be a factor in frequent criminal justice referrals and lengthy treatment required by METH users. Persecutory delusions and auditory hallucinations are the most consistent symptoms of METH-associated psychosis (MAP). MAP has largely been studied in Asian populations and risk factors have varied across studies. Duration, frequency and amount of use as well as sexual abuse, family history, other substance use, and co-occurring personality and mood disorders are risk factors for MAP. MAP may be unique with its long duration of psychosis and …

Data Sharing In Neuroimaging Research, Jean-Baptiste Poline, Janis L. Breeze, Satrajit Ghosh, Krzysztof Gorgolewski, Yaroslav O. Halchenko

Dartmouth Scholarship

Significant resources around the world have been invested in neuroimaging studies of brain function and disease. Easier access to this large body of work should have profound impact on research in cognitive neuroscience and psychiatry, leading to advances in the diagnosis and treatment of psychiatric and neurological disease. A trend toward increased sharing of neuroimaging data has emerged in recent years. Nevertheless, a number of barriers continue to impede momentum. Many researchers and institutions remain uncertain about how to share data or lack the tools and expertise to participate in data sharing. The use of electronic data capture (EDC) methods …

Early Intervention Of Psychosis And Re! Ections For Programmes In India, Amresh Srivastava

Data and Test Instruments

Mental illness is perhaps the most common and most debilitating among non-communicable diseases. Schizophrenia, for example, normally occurs before the age of 25, affect the most productive years of life. The World Economic Forum graphically illustrates that mental illnesses will be a major contributor to the erosion of gross domestic product over the next 20 years. The developed world has established programs that have proven to be clinically and economically effective and sustainable.[1] Early intervention has played an important role in demonstrating that outcome can be improved if patients are treated in the early phase of illness. It is believed …
