Co-Prescription Network Reveals Social Dynamics Of Opioid Doctor Shopping, Brea L. Perry, Kai Cheng Yang, Patrick Kaminski, Meltem Odabas, Jaehyuk Park, Michelle M. Martel, Carrie B. Oser, Patricia R. Freeman, Yong-Yeol Ahn, Jeffery C. Talbert

Psychology Faculty Publications

This paper examines network prominence in a co-prescription network as an indicator of opioid doctor shopping (i.e., fraudulent solicitation of opioids from multiple prescribers). Using longitudinal data from a large commercially insured population, we construct a network where a tie between patients is weighted by the number of shared opioid prescribers. Given prior research suggesting that doctor shopping may be a social process, we hypothesize that active doctor shoppers will occupy central structural positions in this network. We show that network prominence, operationalized using PageRank, is associated with more opioid prescriptions, higher predicted risk for dangerous morphine dosage, opioid overdose, …


Socioemotional Selectivity And Psychological Health In Amyotrophic Lateral Sclerosis Patients And Caregivers: A Longitudinal, Dyadic Analysis, Suzanne C. Segerstrom, Edward J. Kasarskis, David W. Fardo, Philip M. Westgate Oct 2019

Socioemotional Selectivity And Psychological Health In Amyotrophic Lateral Sclerosis Patients And Caregivers: A Longitudinal, Dyadic Analysis, Suzanne C. Segerstrom, Edward J. Kasarskis, David W. Fardo, Philip M. Westgate

Psychology Faculty Publications

Objective: Socioemotional selectivity theory predicts that as the end of life approaches, goals and resources that provide immediate, hedonic reward become more important than those that provide delayed rewards. This study tested whether these goal domains differentially affected psychological health in the context of marital dyads in which one partner had been diagnosed with amyotrophic lateral sclerosis (ALS), a life-limiting disease.

Design: ALS patients (N = 102) being treated in three multidisciplinary clinics and their spouses (N = 100) reported their loneliness, financial worry and psychological health every 3 months for up to 18 months.

Opportunities For Self-Evaluation Increase Student Calibration In An Introductory Biology Course, Jennifer L. Osterhage, Ellen Usher, Trisha A. Douin, William M. Bailey Jun 2019

Opportunities For Self-Evaluation Increase Student Calibration In An Introductory Biology Course, Jennifer L. Osterhage, Ellen Usher, Trisha A. Douin, William M. Bailey

Biology Faculty Publications

Accurate self-evaluation is critical for learning. Calibration describes the relationship between learners’ perception of their performance and their actual performance on a task. Here, we describe two studies aimed at assessing and improving student calibration in a first-semester introductory biology course at a 4-year public institution. Study 1 investigated students’ (n = 310) calibration (the difference between estimated and actual exam performance) across one semester. Students were significantly miscalibrated for the first exam: their predicted scores were, on average, significantly higher than their actual scores. The lowest-performing students had the most inaccurate estimates. Calibration improved with each exam. By …

The Relationship Between Psychological States And Health Perception In Individuals At Risk For Cardiovascular Disease, Kyoung Suk Lee, Frances J. Feltner, Alison L. Bailey, Terry A. Lennie, Misook L. Chung, Brittany L. Smalls, Donna L. Schuman, Debra K. Moser

Family and Community Medicine Faculty Publications

Backgrounds: Perceptions of health are important to motivate people to change behaviors. Non-adherence to healthy behaviors that prevent cardiovascular disease may result from inadequate health perceptions. However, there are few studies investigating relationships between health perceptions and psychological states.

Objective: To determine whether psychological states (ie, depressive symptoms and anxiety) are associated with the congruency between health perception and estimated risk for cardiovascular disease in adults with 2 or more cardiovascular disease risk factors.

Methods: Community dwellers at risk for cardiovascular disease were asked to complete the Patient Health Questionnaire-9 and the anxiety subscale of the Brief Symptom Inventory to …

Perinatal Research and Wellness Center Faculty Publications

PURPOSE: This study aims to describe the association of first trimester co-use of tobacco and cannabis with maternal immune response and psychosocial well-being, relative to tobacco use only.

METHODS: A preliminary midpoint analysis included 138 pregnant women with biologically verified tobacco use, 38 of whom (28%) also tested positive for recent cannabis use. Maternal perceived stress (Perceived Stress Scale), depressive symptoms (Edinburgh Postnatal Depression Scale), and serum immune markers (IL-1β, IL-2, IL-6, IL-8, IL-10, TNFα, CRP, MMP8), were collected, although cytokine data were only available for 122 women.

RESULTS: Participant average age was 29.1 years, approximately half had a high …


An Exploration Of Law Enforcement Officers’ Training Experiences, Training Needs, And Interactions Related To Autism Spectrum Disorder, Kirsten Scheil Railey Jan 2019

An Exploration Of Law Enforcement Officers’ Training Experiences, Training Needs, And Interactions Related To Autism Spectrum Disorder, Kirsten Scheil Railey

Theses and Dissertations--Educational, School, and Counseling Psychology

Although research confirms the effectiveness of training to improve law enforcement officers’ awareness and knowledge of people with intellectual disability, learning disabilities, and mental health disorders (Bailey, Barr, & Bunting, 2001; McAllister, Bailey, & Barr, 2002; Scantlebury et al., 2017; Wood & Watson, 2017), research related to the efficacy of autism-specific law enforcement training is limited. In order to provide up-to-date information regarding training for LEOs related to autism spectrum disorder (ASD), a systematic review of the literature was conducted for the first study. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols 2015 (PRISMA), a …


Exploring The Impact Of Autism Awareness Interventions For General Education Students: A Meta-Analysis, Olivia K. Lochner Jan 2019

Exploring The Impact Of Autism Awareness Interventions For General Education Students: A Meta-Analysis, Olivia K. Lochner

Theses and Dissertations--Educational, School, and Counseling Psychology

Autism spectrum disorder (ASD) diagnoses are on the rise, increasing the likelihood of having a student with ASD in the general education classroom. Students with ASD may be included in the general education setting; however, inclusive educational experiences are negative for many students with ASD. ASD awareness interventions have been implemented to help general education students improve their attitudes, behavioral intentions, and understand their peers with ASD. In the current study, empirical articles evaluating the effectiveness of ASD awareness interventions were identified and quantified. Two research questions were addressed: (a)Are ASD awareness interventions effective for general education students? and (b) …


A Not-So Beautiful Mind: A Review Of The Genetics Of Schizophrenia, Lydia Pack Jan 2019

A Not-So Beautiful Mind: A Review Of The Genetics Of Schizophrenia, Lydia Pack

Oswald Research and Creativity Competition

Schizophrenia is often called “the cancer of the brain” because of the lifelong, horrendous implications of the disease. Though research has been conducted on schizophrenia for a century or more, it has just recently been realized how large a role genetics may play in the development of the disease. This review will discuss why research on schizophrenia genes has been difficult, what genes have been found, how the current treatments are being revolutionized, and how to progress in this field. The difficulty in research is due in part to the complex genetics behind the disease as well as possible environmental …


Beyond Telling: A Phenomenology Of Adoptive Parents' Adoption Communication Openness With Early Adolescents, Jane D. Samuel Jan 2019

Beyond Telling: A Phenomenology Of Adoptive Parents' Adoption Communication Openness With Early Adolescents, Jane D. Samuel

Theses and Dissertations--Family Sciences

Despite calls for increased Adoption Communication Openness (ACO) within the adoptive family, research indicates that families still struggle to accomplish the recommended elements and levels of openness. What could be holding families back from this key process? Three focus groups comprised of 17 adoptive parents of early adolescents (aged 10-14) who were age 0-2 at the time of placement were thematically coded. This inductive analysis revealed the complexity rooted in being —sometimes successfully and sometimes not—communicatively open. Four key themes emerged painting a vivid and rich picture of: a) the breadth and depth of this experience; b) the work entailed; …


The Role Of Therapist Multicultural Competency On Treatment Outcomes, Minnah Farook Jan 2019

The Role Of Therapist Multicultural Competency On Treatment Outcomes, Minnah Farook

Theses and Dissertations--Educational, School, and Counseling Psychology

Racial and ethnic minority populations suffer disproportionally from mental health disparities in the United States (Dillon et al., 2015; Holden et al., 2014). Research has indicated that a lack of culturally competent care contributes to these disparities (Holden & Xanthos, 2009). As multicultural competencies (American Psychological Association [APA], 2002; Council of National Psychological Associations for the Advancement of Ethnic Minority Interests, 2003) have been widely endorsed and implemented in professional organizations and training programs, research on their need and usefulness has increased over the last three decades (Worthington et al., 2007). However, the majority of research on multicultural competencies has …

Effects Of Naltrexone On Alcohol And Nicotine Use In Female P Rats, Usman Z. Hamid, Sarah E. Maggio, Meredith A. Saunders, Kimberly Nixon, Mark A. Prendergast, Richard L. Bell, Michael T. Bardo

Posters-at-the-Capitol Presentations

The objective of the present study was to determine the effectiveness of the opioid antagonist naltrexone at reducing the consumption of EtOH and nicotine in female alcohol-preferring (P) rats. P rats have been selectively bred to have a genetic predisposition for alcohol abuse, which allows them to be used as an animal model of alcoholism. P rats readily self-administer i.v nicotine (Le et al., 2016), have EtOH consumption during adolescence that is similar to that seen in adulthood, and operantly respond for EtOH until they are impaired/intoxicated (Bell et al., 2006). Thus, P rats are a useful model for studying …


When Brain Stimulation Backfires, Sarah Beth Bell Jan 2019

When Brain Stimulation Backfires, Sarah Beth Bell

Theses and Dissertations--Psychology

tDCS brain stimulation does not always work in the intended direction. It has been found to sometimes worsen behavior rather than improve it. A preliminary study shows that people high on sensation-seeking and lack of premeditation were prone to reverse effects of tDCS on performance on a Stop Signal Task. Both of these constructs are related to dopamine levels. Study 2 seeks to intentionally cause a reverse effect of tDCS by increasing participants’ dopamine levels via caffeine. There was not a significant interaction between tDCS and caffeine on errors on the Stop Signal Task in this study. However, other factors …

METHODS: This study was a single group pre-test, post-test interventional study design. The sample population consisted of the parents/guardians of 30 school-aged children diagnosed with ADHD (5-12 years) recruited from the University of Kentucky Developmental and Behavioral Pediatrics Clinic between November 2019 and February 2020. Parents completed a survey about their child’s daily screen time exposure (tablets/cell phones, laptops/computers, video games, and television) and were educated how screen time can exacerbate ADHD symptoms, …


Consumer Embarrassment – A Meta-Analytic Review And Experimental Examination, Alexander H. Ziegler Jan 2019

Consumer Embarrassment – A Meta-Analytic Review And Experimental Examination, Alexander H. Ziegler

Theses and Dissertations--Marketing and Supply Chain

This dissertation consists of two essays that discuss the influence of embarrassment on consumers. In the first essay, I examine consumers’ coping responses to embarrassment in a meta-analytic review. In essay two, I utilize an experimental approach to investigate the impact of embarrassing encounters on unrelated consumers who merely observe the situation.

In the first essay, the meta-analysis is guided by findings in the literature that demonstrate embarrassment can both promote and detract from consumer well-being. However, despite being investigated for decades, little is known about how consumers cope with embarrassing situations, and when and why consumers respond in positive …

Functional Analyses: A Comparison Of Isolated And Synthesized Contingencies, Devin N. Graley Jan 2019

Functional Analyses: A Comparison Of Isolated And Synthesized Contingencies, Devin N. Graley

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

The purpose of the study was to compare traditional functional analysis procedures (isolated contingencies) to functional analysis procedures which are modified to include nuanced environmental variables (synthesized contingencies) for children in an outpatient setting in order to determine sensitivity to the isolated or synthesized contingencies. A multi-element design embedded into a multi-treatment design was used to evaluate differentiated rates of challenging behavior across the two analyses for three children exhibiting challenging behaviors. The results supported the utility of the traditional functional analysis (FA) procedures when compared to that of the interview informed synthesized contingency analysis (IISCA) for one of three …


Suicide Attitudes And Terror Management Theory, Athena Kheibari Jan 2019

Suicide Attitudes And Terror Management Theory, Athena Kheibari

Theses and Dissertations--Social Work

Virtually every mental health problem carries stigma, but suicide appears to run so counter to our accumulative, achievement-oriented society, that it poses even greater threat of stigma. While suicide is inherently troubling in that it opposes the fundamental human instinct for self-preservation, the tendency to stigmatize and reject individuals affected by suicide appears to be counterproductive and excessive. Hence, the purpose of this three-manuscript dissertation is to gain a more nuanced understanding of suicide attitudes from an exploratory and terror management theory perspective. More specifically, this dissertation attempts to answer three general questions: (1) how do suicide attitudes differ from …


Defining Infidelity And Identifying Offending Spouses, Yabin Tang Jan 2019

Defining Infidelity And Identifying Offending Spouses, Yabin Tang

Theses and Dissertations--Family Sciences

Research on infidelity has suffered from inconsistency in how infidelity has been operationalized across studies. This study was designed to advance methodological considerations for defining infidelity and identifying offending spouses. A subjective definition of infidelity was obtained from each respondent via both closed- and open-ended items. The open-ended responses were applied to explore the definition of infidelity. Additionally, an indirect questioning method was adopted to identify offending spouses according to their own subjective definitions of cheating and test the effectiveness of this approach relative to direct questioning for identifying offending spouses. Furthermore, gender differences in acknowledging infidelity through both direct …


The Effects Of Parental Divorce And Remarriage On Emerging Adult’S Romantic Attachment Styles, Bailey Mortis Jan 2019

The Effects Of Parental Divorce And Remarriage On Emerging Adult’S Romantic Attachment Styles, Bailey Mortis

Theses and Dissertations--Family Sciences

This study shined light on the gap in literature about the impact of communication and involvement of stepparents has on emerging adult’s romantic attachment styles. A sample of 289 college students between the ages of 18 and 22 at the University of Kentucky was recruited to complete an online survey about their perceived experience with their stepparent and parental figures and the effects on their romantic attachment styles. Parental involvement in children’s lives and having good communication, sets the foundation for individuals to have secure attachment styles. Emerging adults who experience parental figures and stepparents as being uninterested or passive …

Caregivers Of Parents With Alzheimer’S Disease: Quality Of Life For Caregivers: Perspectives & Family Dynamics, Matthew Cornu

Theses and Dissertations--Family Sciences

This study furthers Alzheimer’s family literature regarding the impact of caregiver attachment, readiness to provide care, and caregiver quality of life. A sample of 33 participants caring for a parent with Alzheimer’s disease in the state of Kentucky was recruited to complete a questionnaire for the study. The questionnaire consisted of an online survey about participants’ experiences and attachments growing up with their parents, their experiences becoming caregivers to their parents with Alzheimer’s disease, and participants’ current perspectives of their own quality of life. Positive perspectives in regards to quality of life among caregivers seem to be a predictor of …


Developmental Sequelae In Language, Empathy, Self-Control, And Psychopathy From Infancy To Middle Adolescence, Magda Javakhishvili Jan 2019

Developmental Sequelae In Language, Empathy, Self-Control, And Psychopathy From Infancy To Middle Adolescence, Magda Javakhishvili

Theses and Dissertations--Family Sciences

The present empirical work aims to discern the underlying mechanisms of purported developmental links among several key human characteristics including language skills, self-control, empathy, and psychopathic traits. Accordingly, three interrelated studies are carried out testing the longitudinal associations of various kinds (e.g., direct, indirect, bidirectional) among these constructs. All three studies are conceptually framed in consideration of the extant research and relevant theories. They employ the data set provided by the National Institute of Child Health and Human Development of Early Child Care and Youth Development Study of N = 1,364 children followed from infancy through middle adolescence.

A Closer Look At Internet Addiction, Jakub Mikuška Jan 2019

A Closer Look At Internet Addiction, Jakub Mikuška

Theses and Dissertations--Family Sciences

Based on a sample of 1,012 late adolescents and young adults (ages 18-26), the current three interrelated studies tested a series of specific questions and hypotheses focused on understanding Internet Addiction.

Study 1 sought to directly compare psychometric properties of four of the most widely used Internet addiction scales based on citation metrics (Internet Addiction Test, Problematic Internet Use Questionnaire, Generalized Problematic Internet Use Scale 2 and Chen Internet Addiction Scale), and to aggregate the best items across all scales into a new measure using bifactor IRT analyses. The resulting 10-item Aggregated Internet Addiction Scale (AIAS) consists of the best …


Empirical Assessment Of Callous-Unemotional Traits In Preschool: A Comparison Of Confirmatory Factor Analysis And Network Analysis, Pevitr Singh Bansal Jan 2019

Empirical Assessment Of Callous-Unemotional Traits In Preschool: A Comparison Of Confirmatory Factor Analysis And Network Analysis, Pevitr Singh Bansal

Theses and Dissertations--Psychology

Callous – unemotional (CU) traits are a key factor in understanding the persistence and severity of conduct problems. The factor structure of CU traits has been primarily examined through confirmatory factor analysis (CFA) in childhood and adolescent samples, yet little research has examined the structure of CU traits in preschool. Further, current CFA models have yielded poor – to – marginally acceptable fit, suggesting the need for a more nuanced approach in understanding the structure of CU traits in early childhood using an interitem approach (i.e., network analysis). Within a sample of 109 preschool children (M age = 4.77, …


The Effect Of Posttraumatic Stress And Trauma-Focused Disclosure On Experimental Pain Sensitivity Among Trauma-Exposed Women, Caitlyn Olivia Hood Jan 2019

The Effect Of Posttraumatic Stress And Trauma-Focused Disclosure On Experimental Pain Sensitivity Among Trauma-Exposed Women, Caitlyn Olivia Hood

Theses and Dissertations--Psychology

Previous studies evaluating the impact of trauma history and PTSD on pain sensitivity yield inconsistent findings; the presence of trauma-related negative affective states may account for these discrepancies. Therefore, the proposed study aimed to evaluate the effect of trauma-related negative affect and PTSD symptoms on sensory and affective components of pain sensitivity among trauma-exposed women. Adult women (N = 87) with low and high PTSD symptoms underwent an emotional disclosure paradigm, during which they wrote about a traumatic event or a neutral topic. Participants then completed a pain induction procedure. Compared to women with low PTSD symptoms, women with …


Development Of A Translational Model Of Co-Use Of Alcohol And Nicotine For Testing Potential Pharmacotherapies, Sarah Elizabeth Maggio Jan 2019

Development Of A Translational Model Of Co-Use Of Alcohol And Nicotine For Testing Potential Pharmacotherapies, Sarah Elizabeth Maggio

Theses and Dissertations--Psychology

Co-users of alcohol and nicotine are the largest group of polysubstance users worldwide. Although pharmacotherapies are available for alcohol (EtOH) or tobacco use disorders individually, it may be possible to develop a single pharmacotherapy to treat heavy drinking tobacco smokers through capitalizing on the commonalities in their mechanisms of action. Towards this goal, several models of concurrent access to EtOH and nicotine were explored as potential preclinical models of co-use using female alcohol-preferring (P) rats. Additionally, potential pharmacotherapeutics for the treatment of EtOH and nicotine co-use disorder were tested using different variations of our model. Treatments tested included (1) varenicline, …


Measuring Glutamate And Oxygen In Brain Reward Circuits In Animal Models Of Cocaine Abuse And Decision-Making, Seth Richard Batten Jan 2019

Measuring Glutamate And Oxygen In Brain Reward Circuits In Animal Models Of Cocaine Abuse And Decision-Making, Seth Richard Batten

Theses and Dissertations--Psychology

Drug-specific reward and associated effects on neural signaling are often studied between subjects, where one group self-administers drug and a separate group self-administers a natural reinforcer. However, exposure to drugs of abuse can cause long-term neural adaptations that can affect how an organism responds to drug reward, natural reward, and their reward-associated stimuli. Thus, to isolate drug-specific effects it is important to use models that expose the same organism to all of the aforementioned. Multiple schedules provide a means of dissociating the rewarding effects of a drug from the rewarding effects of food within a single animal. Further, drug users …


Effects Of Multisensory Stop Signals On Sensitivity To Alcohol-Induced Disinhibition In Drinkers With Adhd, Alexandra R. D'Agostino Jan 2019

Effects Of Multisensory Stop Signals On Sensitivity To Alcohol-Induced Disinhibition In Drinkers With Adhd, Alexandra R. D'Agostino

Theses and Dissertations--Psychology

Multisensory environments facilitate behavioral functioning in humans. The redundant signal effect (RSE) refers to the observation that individuals respond more quickly to stimuli when information is presented as multisensory, redundant stimuli rather than as a single stimulus presented to either modality alone. Our studies show that the disinhibiting effects of alcohol are attenuated when stop signals are multisensory versus unisensory. The present study expanded on this research to test the degree to which multisensory stop signals could also attenuate the disinhibiting effects of alcohol in those with attention-deficit hyperactivity disorder (ADHD), a clinical population characterized by poor impulse control. The …


Posttraumatic Stress And Risky Sex In Trauma-Exposed College Students: The Role Of Personality Dispositions Toward Impulsive Behavior, Jessica Flores Jan 2019

Posttraumatic Stress And Risky Sex In Trauma-Exposed College Students: The Role Of Personality Dispositions Toward Impulsive Behavior, Jessica Flores

Theses and Dissertations--Psychology

Posttraumatic stress disorder (PTSD) has been linked to heightened engagement in risky sexual behavior (RSB) across diverse samples, and impulsivity has been postulated as a potential linkage (Weiss et al., 2012). Limited information has been published on the role that impulsivity can play in strengthening the relationship between PTSD and RSB in college students. The current study examined the moderating role of impulsivity dispositions: negative/positive urgency, (lack of) perseverance, sensation seeking, and (lack of) premeditation on the association between PTSD symptoms and past-year RSB among a sample of 221 undergraduate students (77.4% female) with at least one DSM-5 defined traumatic …
