Adverse Childhood Experiences Among Adolescent Girls In Residential Treatment: Relationship With Trauma Symptoms, Substance Use, And Delinquency, Akemi E. Mii

Department of Psychology: Dissertations, Theses, and Student Research

Adverse childhood experiences (ACEs) refer to negative events during childhood or adolescence including abuse, maltreatment, and exposure to household dysfunction (Kalmakis & Chandler, 2014). ACEs are associated with negative outcomes including mental and behavioral health concerns and offending (Fox et al., 2015). The risk of negative outcomes associated with ACEs increases when an individual experiences polyvictimization (experiencing multiple types of adverse events; Felitti et al., 1998; Finkelhor et al., 2011). A majority of adolescents served by residential treatment programs (RTPs) have experienced polyvictimization (Briggs et al., 2013). Research examining juvenile offending and youth delinquency has focused on boys. Thus, research …

Ptsd And Dysfunctional Parenting: Emotional And Biological Mechanisms, Molly Franz

Department of Psychology: Dissertations, Theses, and Student Research

Women are disproportionately at risk for developing PTSD following exposure to trauma. Among its many harmful effects, PTSD is associated with a range of negative family outcomes, including impairments in parenting behaviors. Despite the prevalence of PTSD and its impact on parenting, little is known about the mechanisms responsible for this association. The present project addressed this gap by examining the impact of PTSD on dysfunctional parenting behaviors in a lab setting. Based on prior theory and empirical evidence, I expected that a diagnosis of PTSD would be associated with more dysfunctional parenting (i.e., harsh/overreactive and lax/permissive behaviors) during routine …

Making A Large Class Feel Small Using Social Psychology: Introducing Teams To Improve Performance And Learning In A Large-Enrollment Course, Bethany Johnson

Department of Psychology: Dissertations, Theses, and Student Research

Large-enrollment lecture-based classes are increasingly common in higher education. As an alternative approach, active learning methods are meant to develop academic skills and improve understanding of course content. Group work is an effective form of active learning, but students typically despise it. Social psychological small group theory can inform teachers about the characteristics of small groups that influence their capability to improve learning, so that teachers can design more effectual group work for their classes. This study examined what effect introducing permanent teams into a large enrollment class had on students’ sense of classroom community and their learning outcomes, using …

A Test Of A Conceptual Model Of Sexual Self-Concept And Its Relation To Other Dimensions Of Sexuality, Arielle R. Deutsch

Department of Psychology: Dissertations, Theses, and Student Research

One theoretical concept that has received modest attention in contemporary sexuality research is the sexual self, particularly focusing on sexual self-concept (SSC). While research on the sexual self has expanded over the past 20 years, there is a lack of cohesion within this research that has culminated in a collection of SSC models that, while sharing certain factors, are dissimilar from each other. Therefore a unified conceptual model of SSC needs to be empirically established. Additionally, little research has examined potential differences between genders in how SSC is expressed, as most SSC research focuses exclusively on women. Finally, understanding of …

Psychotherapy Clients’ Online Behavior And Opinions Regarding Internet Searches Conducted By Therapists, Emily B. Gale

Department of Psychology: Dissertations, Theses, and Student Research

The Internet has become possibly the most popular medium to find information and communicate in our society. For the field of psychology, the Internet offers a new way to collect data and communicate with both study participants and, for practicing psychologists, possibly clients. Little is known, however, about the implications of interacting with clients online. The existing empirical studies in this area (DiLillo & Gale, 2011; Lehavot, Barnett, & Powers, 2010; Taylor et al., 2010) have focused on psychology graduate students’ actions online. These studies highlight the importance and paucity of research regarding the online behaviors of psychotherapy clients and …

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 …

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 …

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 …

Motivation & Loss Aversion In The Health Savings Account Paradigm, Michael Holtje

Department of Psychology: Dissertations, Theses, and Student Research

This investigation examined the role of “loss aversion” and consumers’ motivational orientations in the context of healthcare purchasing under the individual account paradigm and the defined benefit (insurance) paradigm. Specifically, this dissertation investigated (1) whether Health Savings Accounts (HSAs) encourage more prudent health care spending compared to traditional health insurance plans and (2) the impact of individuals' motivational preferences (either towards “gains” or towards “losses”) between decision tasks under each type of health plan.

Three experiments varied the type of healthcare plan that consumers had and the manner in which they received information (either as a “gain” or “loss”). The …

Latino Adolescent Adjustment: An Examination Of Cultural Values, Maria I. Iturbide

Department of Psychology: Dissertations, Theses, and Student Research

In the U.S., 22% of children under the age of 18 are Latino and 52% of Latino children have at least one parent who is foreign-born (Fry & Passel, 2009). Latinos are likely to experience acculturative strains associated with a range of negative outcomes such as academic underachievement. A mixed method sequential explanatory design was used to examine the protective effects of cultural factors that may ameliorate the negative effects of acculturative strains on psychological and academic adjustment.

The quantitative phase of the study examined whether biculturalism and ethnic identity would reduce the negative influence of acculturation strains on adjustment …

Interpersonal Aggression Perpetration: Static And Emotion Regulation Risk Factors, Jill Panuzio

Department of Psychology: Dissertations, Theses, and Student Research

Intimate partner aggression (IPA) is a serious public health problem for both men and women in the United States. With aspirations of alleviating the significant negative effects of IPA, a substantial body of literature has been devoted to uncovering risk factors for IPA perpetration. Much of this research has focused on static, or relatively stable, factors that may influence IPA, such as life stress, distress tolerance, rumination, and jealousy. However, considering situational variables that influence individuals more proximally to aggressive acts, in conjunction with these static factors, may provide more precise prediction of partner aggression. Current theoretical and empirical work …

The Development Of Future Orientation: Underpinnings And Related Constructs, Sarah J. Beal

Department of Psychology: Dissertations, Theses, and Student Research

Future orientation has been conceptualized in a variety of ways across literatures in psychology, sociology, education, and vocation. The lack of a shared definition and measurement across theoretical perspectives has resulted in a challenge in comparing findings across literatures and organizing results in a way that provides a coherent sense of how future orientation impacts later outcomes. Trommsdorff (1979) provided a comprehensive definition of future orientation that included eight dimensions: extension, detail, domain, affect, motivation, control, sequence of events, and number of cognitions. Study 1 was designed to test this definition using measures from five prominent theories of future orientation …

Visual Attention And Social Anxiety: Oculomotor Behavior When Threatened, Jacqueline S. Singh

Department of Psychology: Dissertations, Theses, and Student Research

A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study addressed some inconsistencies and gaps in the literature using eye tracking methodology. Participants with high and low trait social anxiety were randomly assigned to either give a speech or to watch a video of another individual delivering a speech (state social anxiety manipulation). Next, participants were asked to engage in a free view task in which pairs of emotional facial stimuli (angry-happy, angry-neutral, or happy-neutral) were presented for 3 s. Eye movements were monitored …

Exploratory Analyses Of A Developmental Conceptualization Of Insight And Treatment Outcomes Of Individuals With Serious Mental Illness In Psychiatric Rehabilitation, Ashley R. Wynne

Department of Psychology: Dissertations, Theses, and Student Research

The purpose of the present study was to further examine the relationship between adolescent psychiatric pathology and SMI by assessing the relationship between prior mental health services before the age of 18 and time of assessment on people’s insight into their illnesses. A secondary relationship between adolescent psychiatric pathology and functioning in a variety of domains before, during, and after treatment was assessed. Overall, there was an inconsistent pattern of results and partial support of hypotheses. The current study was a retrospective longitudinal study in which assessments were given to 308 participants in an inpatient psychiatric rehabilitation unit every 6 …

Why Confronting Sexism Works: Applying Persuasion Theories To Confronting Sexism, Amy Hillard

Department of Psychology: Dissertations, Theses, and Student Research

Speaking up about or confronting prejudice creates more positive attitudes, but the mechanism underlying confrontation’s prejudice reducing effect remains unclear. Based on an integration of the confronting prejudice and persuasion literatures, I expected that observing a confrontation (vs. no confrontation) reduces prejudice and discrimination; that elaborating on confrontation messages reduces prejudice and discrimination more than confrontation alone; and that elaborating on confrontation messages causes attitude change that lasts longer than confrontation alone. Participants were recruited to complete measures of sexism and feelings toward subtypes of women across three time points (i.e., pre-test, lab manipulation, and post-test). During the lab manipulation, …

When Knowing Just Isn't Enough: Examining The Role Of Moral Emotions In Health Decision Making Using The Theory Of Planned Behavior, Kate Duangdao

Department of Psychology: Dissertations, Theses, and Student Research

A proposed integrated Theory of Planned Behavior (TPB) model aimed to examine the role of moral emotions and two health outcomes: prosocial behaviors and smoking outcomes. Based on Tangney’s work with shame and guilt-proneness, it was expected that those more prone to guilt would engage in more prosocial behaviors and those more prone to shame would engage in more smoking behaviors. Prosocial behaviors were found to be negatively associated with smoking outcomes. However, results suggested that guilt and shame-proneness seem to function similarly in predicting behavioral outcomes. Components within the TPB were generally positively correlated with each health outcome, however …

Child/Adolescent Sexual Abuse And Alcohol: Proposed Pathways To Problematic Drinking In College Via Ptsd Symptoms, Emotion Dysregulation, And Dissociative Tendencies, Alicia K. Klanecky

Department of Psychology: Dissertations, Theses, and Student Research

Research has discussed the use of alcohol to self-medicate posttraumatic stress (PTSD) symptoms following child/adolescent sexual abuse (CASA). Less research has examined the self-medication hypothesis in college students. Further, investigation of the self-medication hypothesis generally precludes the integration of additional psychological vulnerabilities that may impact students’ alcohol consumption. Supported by the “dynamic” stress-diathesis perspective, emotion regulation (ER) difficulties and insufficient dissociative tendencies existing prior to and potentially altered after CASA exposure may relate to problematic alcohol use. The current study aimed to provide an initial, cross-sectional examination of 1) the relations between CASA exposure severity and alcohol use, 2) the …

Reassessing The Architecture Of The Health Beliefs Models In Low-Income Diverse Families, Krista B. Highland

Department of Psychology: Dissertations, Theses, and Student Research

Health beliefs contribute to health outcomes. These health beliefs extend to include health beliefs parents have regarding their children’s health. However, the role of parental health beliefs remains unexplored among a low-income population. This study aims to assess these beliefs and the effects they have on child health. Furthermore, this study aims to delineate potential belief differences between socioecological-level groups (e.g. population density, Latino identification, and insurance coverage). The long-term goal is to understand the relationships among various personal health beliefs and parental health beliefs, psychosocial factors, community factors, cultural factors, organizational factors, and healthcare perceptions among this at-risk population. …

Department of Psychology: Dissertations, Theses, and Student Research

Ten members of Lincoln Fire and Rescue in Lincoln, Nebraska agreed to participate in a thirteen week tactical strength and conditioning fitness program conducted by Athology Inc. that included a Physiological, Physical, and Cognitive Component. Participants completed three workouts per week lasting approximately 90 minutes each, conducted by fitness trainers from Athology Inc. Participants completed lab draws at the beginning and end of the program as well as an EKG at the onset of the program, conducted off-site at a local hospital. Participants completed performance and agility testing at the onset and end of the program. Lastly, participants completed cognitive …

Policy And Practice: An Analysis Of The Implementation Of Supported Employment In Nebraska, Heng-Hsian N. Liu

Department of Psychology: Dissertations, Theses, and Student Research

Supported employment (SE) is an evidence-based practice (EBP) for persons with severe mental illness (SMI) aimed at competitive employment. SE has a large evidence base, demonstrating outcomes across settings and populations. SE has been promoted by the Centers for Medicare and Medicaid Services (in the U.S. Department of Health and Human Services) and widely disseminated through the internet via a “community tool-kit” sponsored by the Substance Abuse and Mental Health Services Administration.

The SE literature expresses the opinion that state governments can successfully implement SE. Researchers have developed implementation guidelines and identified stages of statewide implementation; however, most SE implementation …

Juror Perceptions Of Juveniles Transferred To Criminal Court: The Role Of Generic Prejudice And Emotion In Determinations Of Guilt, Megan Beringer Jones

Department of Psychology: Dissertations, Theses, and Student Research

Research examining juror perceptions of juveniles tried as adults has provided mixed results, with some studies providing evidence of bias against juveniles tried as adults, and others finding no evidence of this bias. The present research aimed to clarify this issue by examining the roles of generic prejudice and emotion in jurors’ judgments of juveniles tried as adults. Study 1 assessed which stereotypes people associate with juveniles tried as adults compared to juveniles tried in juvenile court and adults tried in criminal court. Study 2 examined to what extent angry, fearful, sad, and neutral mock jurors used these stereotypes to …

The Recovery Of Cognitive And Social Cognitive Functioning In Response To Social Cognition Interaction Training Administered In Community Settings: A Longitudinal Study, Lena Reddy

Department of Psychology: Dissertations, Theses, and Student Research

Psychosocial rehabilitation for persons with Serious Mental Illness (SMI) encompasses recovery of functioning in a broad array of domains, including neurocognitive, social cognitive, interpersonal, occupational, and self-care abilities. There is extensive evidence that improvements in these domains are possible as a result of targeted interventions, and that these improvements may generalize to other areas of daily functioning. The current study explored rehabilitative change over time among adults with SMI that were attending outpatient day centers. Social Cognition and Interaction Training (SCIT), a cognitive-behavioral skills-training modality, was implemented during the time period in which the data was collected. Forty adults participated …

Adapting An Evidence-Based Intervention To Improve Social And Behavioral Competence In Head Start Children: Evaluating The Effectiveness Of Teacher-Child Interaction Training, Christopher Campbell

Department of Psychology: Dissertations, Theses, and Student Research

Empirical studies indicate that as many as 35% of Head Start children meet the diagnostic criteria for oppositional defiant disorder or conduct disorder (Webster-Stratton & Hammond, 1998). Without early intervention, these problematic behaviors may become stable across childhood and adolescence (Campbell, 1995), increasing the likelihood of academic problems, school drop-out, substance abuse, delinquency, and violence (Snyder, 2001). Head Start children are also more likely to enter school with significant deficits in social-emotional readiness, with a many as 40% demonstrating delays in social competencies and communication abilities (Kaiser et al., 2000). Longitudinal research indicates that early gaps in social competence for …

Is Everyone Rated Equal? An Examination Of Factors Related To Sexual Risk In Ethnically Diverse Male Adolescents Who Have Sexually Offended, Veronica Chavez

Department of Psychology: Dissertations, Theses, and Student Research

As the juvenile justice system has evolved, there has been a need for clinicians to make judgments about risk posed by adolescents who have committed sexual offenses. There are inherent difficulties in attempting to assess risk for violence among adolescents due to the developmental changes taking place and the absence of well-validated instruments to guide risk prediction judgments. With minority groups increasing in numbers in the U.S., it is likely that professionals will encounter minority individuals when conducting risk assessments. Overall questions regarding race/ethnicity have been neglected and there are few if any published research that explores risk factors with …

Predicting Problematic Approach Behavior Toward Politicians: Exploring The Potential Contributions Of Control Theory, Douglas Owen Cacialli

Department of Psychology: Dissertations, Theses, and Student Research

The potential merits of Carver and Scheier's (1981) control theory in the prediction of targeted violence are reviewed and several novel indicators of risk that are consistent with this theory are suggested for study. It was hypothesized that: (a) similarity between inappropriate contact with politicians and extremist group literature and writings; (b) the temporal proximity to violent or otherwise criminal actions and notable anniversaries of such groups; (c) detailed specification of a plan to engage in problematic approach behavior, and; (d) self-focus, will be significant predictors of problematic approach behavior. A sample of 506 individuals who engaged in threatening or …

The Influence Of Childhood Abuse On Longitudinal Course Of Recovery In Psychiatric Rehabilitation, Kee-Hong Choi

Department of Psychology: Dissertations, Theses, and Student Research

Background: Empirical outcome studies have identified specific symptomatic, cognitive, emotional and functional sequelae of childhood abuse in people with severe mental illness (SMI). These findings illuminate the need for an integrated understanding of biological, psychological, environmental, and developmental aspects of SMI. Purpose: The purpose of the present study includes the following: 1) to examine reliability and validity of the comprehensive child abuse rating system in a sample of individuals with SMI, 2) to examine the influence of childhood abuse severity on recovery of psychotic symptoms, neurocognition and social-cognition, and social functioning in people with SMI during 12 months of inpatient …

Exploring Online Sexually Explicit Material: What Is The Relationship To Sexual Coercion?, Valerie Gonsalves

Department of Psychology: Dissertations, Theses, and Student Research

With the popularity of the Internet, it is easy to access sexually explicit material. Past research has demonstrated that exposure to sexually explicit material in traditional formats (i.e. magazines and videos) may have an influence on male attitudes and behaviors towards females, but these effects appear to be minimal and dissipate over the long term. Though the body of literature examining Internet sexually explicit material is smaller, researchers have found little to no effects on attitudes or aggressive behaviors immediately after exposure. However, research regarding exposure to online sexually explicit material has not included forensically relevant variables.

Previous research has …

The Quality Of Spousal Social Support As A Moderator Of The Associations Between Child Maltreatment Severity And Adult Trauma Symptoms, Sarah E. Evans

Department of Psychology: Dissertations, Theses, and Student Research

Child maltreatment has been linked to a myriad of long-term difficulties, including trauma symptomatology. However, not all victims experience long-term distress. Thus, a burgeoning area of research focuses on factors that may impede or facilitate resiliency to the psychological correlates of child maltreatment. Specifically, the severity of the abusive acts may be associated with greater long-term difficulties. To date, however, with the exception of child sexual abuse, few studies have examined the severity of maltreatment as a risk factor in the development of trauma symptoms. In contrast, social support has been theorized to contribute to resiliency following abuse. However, to …
