Treatment Preferences And Outcome In A Randomized Controlled Trial For Depression Comparing Supportive-Expressive Therapy To Medication And Pill Placebo, Sophia Elsie Winter

Doctoral Dissertations

Previous research regarding the relationship between patient treatment preferences on outcome has been equivocal, with some studies finding a significant relationship between preference match and outcome, and others finding no such evidence. This study examines the effect of patient treatment preference match on outcome using data from a previously published randomized controlled trial comparing supportive-expressive therapy (SET), to antidepressant medication plus clinical management, and to pill-placebo plus clinical management. The original study included 156 participants receiving treatment at the Center for Psychotherapy research at the University of Pennsylvania in Philadelphia, PA. This study is the first to examine the relationship …

Academic Work Ethic In Middle School Students: Extending Scale Research And Investigating Construct Validity, Emily Pendergrast Taylor

Doctoral Dissertations

This three-study dissertation was designed to: 1) extend the research on Parkhurst’s (2013) Academic Work Ethic-Student (AWE-S) scale, 2) develop and analyze reliability of the Academic Work Ethic-Teacher (AWE-T) scale, and 3) expound on the construct validity of academic work ethic by comparing AWE-S and AWE-T scores to external factors (i.e., grades, perceived support, and parental work ethic) and Grit (Duckworth, 2007), a similar construct. Research was conducted in both rural and urban middle schools in Tennessee and included student, teacher, and parent participants.

Both scales were found to have high reliability coefficients and stable factor structures. Student scale (AWE-S) …

The Effect Of Unique Labels On Face Perception In Infancy, Hillary R. Hadley

Doctoral Dissertations

Faces are universally important for a variety of reasons, ranging from identifying individuals to conveying social information. During the first year of life, infants’ experience with commonly encountered face groups shapes how infants perceive familiar and unfamiliar faces. Between 6 and 9 months of age, infants become worse at differentiating among individual faces from unfamiliar face groups (e.g., other-species faces), a process known as “perceptual narrowing”. Labeling faces from a previously unfamiliar face group has been found to promote individual-level differentiation, as well as expert neural processing for the face group. However, it is currently unclear what influences individual-level labels …

The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas

Doctoral Dissertations

Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …

The Role Of Adoptive Identity In Career Development Of College And Non-College Individuals, Yesel Yoon

Doctoral Dissertations

Identity development is a particularly salient developmental task that begins to take form during adolescence, and consolidation of multiple domains of identity is necessary for achieving successful outcomes in adulthood (Erikson, 1968). The purpose of this study was to examine the role of an ascribed adoptive identity on the individualization of one’s chosen career identity. Adoptive identity was examined using both individual and family-level factors, and career identity was measured across adolescence, emerging adulthood, and adulthood. The present study used a sub-sample of adoptees, adoptive mothers, and adoptive fathers from an ongoing longitudinal research study, the Minnesota/Texas Adoption Research Program …

Detecting Candidate Preknowledge Of Items Using A Predictive Checking Method, Xi Wang

Doctoral Dissertations

In on-demand high-stakes testing programs such as GRE and TOEFL, some items are repeatedly used across test administrations to reduce the cost of developing new items constantly. Item exposure provides an opportunity for examinees to have knowledge of particular test items in advance of their administration. It poses a threat to test security and ultimately will result in invalid test scores. Therefore, many testing programs conduct quality control to monitor test compromise at individual and/or group level. A predictive checking method is proposed in this study to detect examinee preknowledge on exposed items. We consider a scenario where a test …

Infants' Reasoning About Agents' Identity: The Case Of Sociomoral Kinds, Hernando Taborda

Doctoral Dissertations

Recent studies in development psychology suggest that early on infants are able to distinguish characters who display a cooperative behavior from characters who display an antisocial behavior. The current research builds on these findings and aims at determining the extent to which infants possess the sociomoral distinction of “good” and “mean” agents. In particular, we propose that infants represent sociomoral behaviors through kind-based categories. This hypothesis was tested in the current research across 5 different experiments by investigating how infants represent the identity of agents in sociomoral situations. Experiment 1 used a looking-time paradigm to demonstrate 11-month-old infants’ bias to …

Bidirectional Relationships Between Maternal Parenting Behaviors And Conduct Disorder Symptoms In Preschool Children, Benjamin Rolon Arroyo

Doctoral Dissertations

Conduct disorder (CD) symptoms emerge in preschool children, and some evidence for bidirectional effects between maternal parenting behaviors and these symptoms has been found in school-age children and adolescents. However, the strength and pattern of these effects are unknown during the preschool years. The present study examined the bidirectional relationships between several key maternal parenting behaviors (negative affect, warmth, overreactivity, and laxness) and CD symptoms across the preschool years. Participants were 197 preschool children (M = 44.24 months, SD = 3.37; Girls = 92) exhibiting significant behavior problems and their mothers who participated in a 3-year longitudinal study. Maternal …

Identifying Examinees Who Possess Distinct And Reliable Subscores When Added Value Is Lacking For The Total Sample, Joseph A. Rios

Doctoral Dissertations

Research has demonstrated that although subdomain information may provide no added value beyond the total score, in some contexts such information is of utility to particular demographic subgroups (Sinharay & Haberman, 2014). However, it is argued that the utility of reporting subscores for an individual should not be based on one’s manifest characteristics (e.g., gender or ethnicity), but rather on individual needs for diagnostic information, which is driven by multidimensionality in subdomain scores. To improve the validity of diagnostic information, this study proposed the use of Mahalanobis Distance and H^T indices to assess whether an individual’s data significantly departs …

The Effect Of Interruptions On Primary Task Performance In Safety-Critical Environments, Cheryl Ann Nicholas

Doctoral Dissertations

Safety critical systems in medicine utilize alarms to signal potentially life threatening situations to professionals and patients. In particular, in the medical field multiple alarms from equipment are activated daily and often simultaneously. There are a number of alarms which require caregivers to take breaks in complex, primary tasks to attend to the interruption task which is signaled by the alarm. The motivation for this research is the knowledge that, in general, interrupting tasks can have a potentially negative impact on performance and outcomes of the primary task. The focus of this research is on the effect of an interrupting …

Are People Motivated To Experience Emotions For Their Cognitive Impacts? The Motivational Implications Of Cognitive Appraisal Theories Of Emotion, Daniel R. Rovenpor

Doctoral Dissertations

I propose a novel framework for understanding why people want to feel different emotions. I argue that people may be motivated to experience emotions for the cognitive appraisals they are associated with. In an effort to lay the foundation for an appraisal-based model of emotional preferences, I drew upon research on cognitive appraisal theories of emotion, emotional preferences, and basic human motivation. I tested my proposed model by either measuring (Study 1) or manipulating (Studies 2-7) appraisals and measuring emotional preferences, using anger (Studies 1-6) and guilt (Study 7) as specific test cases. I predicted that uncertainty appraisals would lead …

Processing Messages For Reconciliation: What Produces Changes In Attitudes Instead Of Resistance?, Rachel R. Steele

Doctoral Dissertations

Conflicts between groups harm positive intergroup relations. Parties to intergroup conflict have developed a variety of methods for fostering reconciliation following conflicts. Out of these different mechanisms, intergroup apology is the most studied empirically but there are still a number of gaps in this research. To address these gaps, my research brought together intergroup apology research, attitude change and persuasion research, and findings on the role of group identification. In this research I assumed that apologies and other efforts for reconciliation function as persuasive messages for intergroup reconciliation. The research assessed the way in which participants from both victim and …

Using Latent Class Cluster Analysis To Identify And Profile Organizational Subclimates: An Exploratory Investigation Using Safety Climate As An Exemplar, Amy Frost Stevenson

Doctoral Dissertations

Organizational climate refers to the shared meaning organizational members attach to the events, policies, practices, and procedures they experience as well as to the behaviors they see being rewarded, supported, and expected (Schneider, Ehrhart, & Macey, 2011). Climate scholars have most frequently used referent-shift consensus and dispersion composition models (Chan, 1998) to conceptualize and measure organizational climate. Based on these models, climate emergence has been characterized by low variance or high consensus of individual-level climate perceptions (Chan, 1998; Ehrhart, Schneider, & Macey, 2013; Hazy & Ashley, 2011; Kuenzi & Schminke, 2009) within formally defined organizational groups (e.g., work teams).

Evaluating Indicators Of Job Performance: Distributions And Types Of Analyses, Richard J. Chambers Ii

Doctoral Dissertations

Distributions of job performance indicators have historically been assumed to be normally distributed (Aguinis & O'Boyle, 2014; Schmidt & Hunter, 1983; Tiffin, 1947). Generally, any evidence to the contrary has been attributed to errors in the measurement of job performance (Murphy, 2008). A few researchers have been skeptical of this assumption (Micceri, 1989; Murphy, 1999; Saal, Downey, & Lahey, 1980); yet, only recently has research demonstrated that in certain specific situations job performance is exponentially distributed (Aguinis, O'Boyle, Gonzalez-Mulé, & Joo, 2016; O'Boyle & Aguinis, 2012). To date there have been few recommendations in the Industrial-Organizational Psychology literature about how …

Anxiolytic Effects Of Propranolol And Diphenoxylate On Mice And Automated Stretch-Attend Posture Analysis, Kevin Scott Holly

Doctoral Dissertations

The prevention of social anxiety, performance anxiety, and social phobia via the combination of two generic drugs, diphenoxylate HC1 (opioid) plus atropine sulfate (anticholinergic) and propranolol HCl (beta blocker) was evaluated in mice through behavioral studies. A patent published on a September 8, 2011 by Benjamin D. Holly, US 2011/0218215 Al, prompted the research. The drug combination of diphenoxylate and atropine plus propranolol could be an immediate treatment for patients suffering from acute phobic and social anxiety disorders. Demonstrating the anxiolytic effects of the treatment on mice would validate a mouse model for neuroscientist to be used to detect the …

The Relationship Between Executive Functioning And Substance Abuse, John M. Tracy

Doctoral Dissertations

Substance use disorders are a widespread issue in society today with approximately 20 million people in the U.S. alone experiencing drug-related problems (Substance Abuse and Mental Health Services Administration, 2012). However, treatment is often ineffectual with approximately 50% of addicted individuals returning to substance use. One factor found to impact individuals' treatment response is their neuropsychological functioning. Drug-abusers frequently exhibit severe executive functioning impairments across a number of domains, and there is evidence that these deficits may be time and substance-dependent. Executive functions are mental processes critical in motivation, planning, and goal-directed behaviors. With extended abstinence, research suggests cognitive improvements …

Transgender Self-Attitudes: Formation And Change A Qualitative Study, Juliet Ezhil Meggs

Doctoral Dissertations

The current study explored attitudes of transgender people about being transgender and how these attitudes had formed and changed over participants’ lifetimes. Using a qualitative, grounded theory approach (Charmaz, 2003), interviews with 11 transgender adults were coded and analyzed. Two primary categories of attitudes were identified: participant attitudes regarding acceptability of being transgender and attitudes regarding how possible they believed it is to be transgender and/or transition genders. Early in life, most participants had little exposure to the idea of being transgender, and those that knew of it often initially believed that it would too difficult or impossible to transition. …

Examining Consensual Non-Monogamy Among Emerging Adult Samples: A Collection Of Studies, Kayla Marie Sizemore

Doctoral Dissertations

Using multiple methodologies, this collection of manuscripts examined various components of CNM during the period of emerging adulthood. Manuscript one presents a systematic review and critique of the methodology used in research on CNM attitudes and desire among emerging adults between 1974 and 2016. Several methodological characteristics were reviewed across 18 empirical articles, including sample characteristics, recruitment and sampling strategy, measurement, and overall methodology and focus. Despite general commentary among researchers in this field, this review concludes that CNM research has shown little improvement with regard to its methodological limitations since the 1970’s.

The second manuscript contributes to the extant …

Investigating The Role Of Testosterone Signaling At Androgen Receptors In Resiliency To Social Stress, Catherine Tucker Clinard

Doctoral Dissertations

Social experience can alter how individuals cope with stressful events and contribute to individual differences in stress vulnerability. We have previously tested dominant and subordinate male Syrian hamsters (Mesocricetus auratus) in a conditioned defeat model and found that dominant individuals show reduced defeat-induced changes in behavior compared to subordinates. Dominant hamsters also show increased neural activation following social defeat stress in brain regions that regulate social behavior and coping with stress, including the medial amygdala (MeA). Because winning aggressive encounters generates a surge in plasma testosterone and androgen receptors are abundant in the MeA, we tested whether testosterone …

Therapy Dogs In The College Classroom: The Effect Of Dogs On Stress, Anxiety, And Spanish L2 Phonological Learning And Performance, Elaine Maralee Henry

Doctoral Dissertations

Anxiety and stress invoked by the second language classroom setting has the ability to cause numerous detrimental physiological changes which impair the learning process. A more natural, “immersion” type atmosphere is often desired when teaching a second language; however, this is not typically possible with college classes. Therefore, the addition of therapy dogs to college second language classes may be a beneficial solution since therapy dogs are frequently cited as having the ability to lower stress and anxiety in many different settings. Stroking and interacting with a dog may reduce many markers of stress, including blood pressure, heart rate, and …

Examining The Nature And Consequences Of Interfunctional Bias In A Corporate Setting, William Adam Powell

Doctoral Dissertations

Interfunctional bias is examined in this dissertation as a potential barrier to interfunctional cooperation. Interfunctional cooperation is desirable in modern corporate organizations as a contributor to effective service delivery, operations planning, and sales performance. Interfunctional stereotyping, prejudice, and discrimination are hypothesized to relate positively, and together provide the bias-based theoretical basis through which barriers to interfunctional cooperation can be more thoroughly understood. Based on the extant literature in marketing and psychology, competing models of interfunctional bias are developed and hypothesized. In the first of three studies a questionnaire-based survey of supply chain employees’ perceptions of salespeople permitted the examination of …

Burnout In Young Adult Performing Artists, Benjamin Hyun Stocking

Doctoral Dissertations

The purpose of this study was to examine the experience of burnout in adolescent/young adult performing arts (i.e. a World-Class junior drum & bugle corps) at the beginning of their competitive training season. Specifically, this study took particular interest in investigating the predictive influence of psychological variables such as performance anxiety, psychological coping skills, and coping functions in predicting who was more prone to burnout as well as who returned or dropped out after the competitive season.

Data were drawn from an archive of 144 drum corps performers, representing one world class drum and bugle corps at the beginning of …

Ethnic Discrimination And Psychological Distress Among Middle Eastern/Arab Americans: The Roles Of Religiosity, Coping, Ethnic Identity, And Family Connectedness, Ayse Selin Ikizler

Doctoral Dissertations

Despite increased public attention in the past decade towards the Middle East and Arab world, only a small but growing body of research literature investigating the mental health of individuals with ethnic background originating in these countries exists. Given the major stigma associated with being Middle Eastern/Arab (MEA) in the United States, the mental health-related implications for MEA Americans is of particular interest in the present study. Specifically, we investigated (1) the moderating role of religiosity in the link between religious affiliation and ethnic discrimination and (2) potential mediators (coping via internalization, detachment, and drugs/alcohol) and moderators (ethnic identity and …

Native American Young Adults In Their Transition To College, And Persistence Through The First Year, Adrian Alexander Rodriguez

Doctoral Dissertations

This dissertation study focused on a mixed-methods exploration of Native American students’ perceptions of risks and protective factors as they transitioned to college at a predominately White institution (PWI), and navigated through their first year. Due to low numbers of Native Americans at PWIs, individuals have described feeling invisible, which negatively impacts their ethnic identity development, sense of belonging, wellbeing, and retention in college. Factors involving respect, positive relationships, cultural affirmation, and resiliency are associated with success and retention for Native American students.

A mixed-methods model, guided by grounded theory and principles of social justice advocacy provided a reflection on …

Internalized Heterosexism, Religious Coping, And Psychache In Lesbian, Gay, And Bisexual Young Adults, Jon Raymond Bourn

Doctoral Dissertations

Psychache, or unbearable psychological pain (Shneidman, 1993, 1999), has been found to be the most proximal predictor of suicidality. There is evidence that heterosexism (Crain-Gully, 2011), including internalized heterosexism (IH; Bourn & Miles, 2015), is related to psychache among lesbian, gay, and bisexual (LGB) individuals. The current study sought to further examine the relationship between IH and psychache, by identifying potential factors that moderate and mediate the relationship between IH and psychache. It was hypothesized that, in a sample of religiously-identified LGB young adults, (a) IH would be significantly, negatively correlated with positive religious coping (PRC) and significantly, positively correlated …

The Effects Of The Color Wheel System On Disruptive Behavior And Classroom Climate: Validating The Color Wheel In Kindergarten Classrooms, Tiffany Lynn Watson

Doctoral Dissertations

The current study was initiated by a principal who was interested in implementing the Color Wheel System in her school. The purpose of the current study was to empirically validate the classroom management system for kindergarten students. Although there is some evidence that the procedure may be effective with kindergarten students, no scientific procedures have been applied to evaluate the Color Wheel System in kindergarten classrooms. Analyses were conducted on the average inappropriate vocalizations and out-of-seat behavior of the entire class (i.e., 16-17 students) across three classrooms. We also evaluated the effect of the Color Wheel System on students’ perception …

Conformity To Masculine Norms: A Case-Based Time-Series Analysis Of Men In Intergroup Dialogue, Isaac Curtiss Brandt

Doctoral Dissertations

There is an established and growing body of research associating poor health outcomes among men with conformity to socialized masculine gender norms (Bonar et al., 2011; Borsari, Murphy, & Barnett, 2007; Courtenay, 2011). This study explored whether this socialization is subject to change in four individual male participants in a multi-week, small group learning environment called Intergroup Dialogue (IGD). Participants in IGD “closely examine the socially constructed norms and ideologies that guide their (often unconscious) beliefs” (Dessel & Rogge, 2008 p.213). IGD groups met for eight sessions. Pre- and Post-group scores on the Conformity to Masculine Norms Inventory-46 (CMNI) were …

Relationship Qualities: Investigating The Nature Of Self-Identified Couple Strengths And Language Use During A Strengths Interview, Katie Cassandra Wischkaemper

Doctoral Dissertations

Research and practice in couple therapy has been influenced by positive psychology, and other factors, to create a nuanced viewed of relationship health. Relationship strengths are thought to be informative of overall relationship health, possibly even more so than relationship concerns (Gable, Gonzaga, & Strachman, 2006; Sullivan, Pasch, Johnson, & Bradbury, 2010). The present project explored the association between self-identified relationship strengths and couple satisfaction. Then, the study examined the association between self and partner pronoun use and level of couple satisfaction during an interview about relationship strengths.

Aim 1 replicated Gray and colleagues’ (under review) project which examined the …

College Adjustment, Discrimination, And Social Support Among Students Of Color, Daniela Andrea Recabarren

Doctoral Dissertations

Despite efforts to increase underrepresented student enrollment, Students of Color continue to have significantly lower college retention rates compared to their White counterparts on many U.S.college campuses. This study investigated associations between general ethnic discrimination, emotional adjustment to college, and attachment to college in Students of Color at one predominantly White public institution in theSoutheastern U.S. Students who were the first in their immediate family to attend college were compared to those with a parent who attended college. Social support from family and friends at home, as well as social integration in school were investigated as buffers of the impact …

Perceiving Sexual Consent: The Effects Of Gender And Alcohol Use On Perceptions Of Sexual Consent, Sarah Elizabeth Mauck

Doctoral Dissertations

Understanding sexual assault hinges on a firm conceptualization of sexual consent; however, few studies have investigated sexual consent, and much research related to sexual consent relies on traditional sexual script theory rather than a communicative model of sexual consent. The current study addressed gaps in the literature by employing a vignette technique to examine effects of vignette character gender and alcohol use and observer gender on observers’ perceptions of sexual consent for characters presented in a nonconsensual sexual scenario. Participants (N=387) were recruited via MTurk and were administered 1 of 4 randomly assigned vignettes. Participants then responded to items related …
