A Review Of The Role Of Anxiety In Diagnosis Of Children And Adolescents With Autism Spectrum Disorder: A Paradigm Shift In Conceptualization And Diagnosis, Evan Wahlquist

Dissertations

Early evidence of co-occurring anxiety symptoms in children and adolescents with autism spectrum disorder (ASD) dates back to the first descriptions of ASD by Leo Kanner (1943) and Hans Asperger (Frith & Mira, 1992). While current research has identified anxiety disorders as one of the most prevalent co-occurring disorders in children and adolescents with ASD, little is known about the nature of the relationship between these disorders. In an effort to explain these high prevalence rates, recent research has started to investigate the relationship between these two disorders. To join these efforts, this clinical research project explored the role of …

Hippocampal Volume And The Detection Of Mild Cognitive Impairment In An Older Adult Population: Assessing Performance On Cognitive Screeners Administered In-Person And Electronically, Kristen Fabrizi

Dissertations

The present study investigated how performance on in-person and electronic neuropsychological assessment measures predicted subcortical hippocampal volume and cognitive decline consistent with mild cognitive impairment. It was hypothesized that the Montreal Cognitive Assessment would display better predictive strength than the Cogstate Brief Battery when evaluating subcortical hippocampal volume measured via structural magnetic resonance imaging. It was further hypothesized that the Montreal Cognitive Assessment would be more sensitive to predicting group membership to the diagnostic classification of mild cognitive impairment compared to the Cogstate Brief Battery. The sample included 445 older adult participants selected from the Alzheimer’s Disease Neuroimaging Initiative 3. …

Evidence-Based Practices And Self-Efficacy: A Quantitative Study Of Mental Health Counselors Treating Clients With Substance Use Disorder, Carl Bastien

Dissertations

Substance use disorder affects a substantial number of individuals in the United States. The specific problem of this research is that it was not known to what extent their use of evidence-based practices is driven by their sense of self-efficacy. The purpose of this quantitative correlational research was to examine to what extent the use of evidence-based practices covary with a sense of self-efficacy for mental health counselors treating individuals diagnosed with a substance use disorder. The study population was 121 mental health counselors who specialized in substance use disorder treatment who completed a digital survey. The study findings did …

Single-Case Pilot Study For Longitudinal Analysis Of Referential Failures And Sentiment In Schizophrenic Speech From Client-Centered Psychotherapy Recordings, Travis A. Musich

Dissertations

Though computational linguistic analyses have revealed the presence of distinctly characteristic language features in schizophrenic disordered speech, the relative stability of these language features in longitudinal samples is still unknown. This longitudinal pilot study analyzed schizophrenic disordered speech data from the archival therapy audio recordings of one patient spanning 23 years. End-to-end Neural Coreference Resolution software was used to analyze transcribed speech data from three therapy sessions to identify ambiguous pronouns, referred to as referential failures, which were reviewed and confirmed by multiple raters. Speech samples were analyzed using Google Cloud Natural Language API software for sentiment variables (i.e., score, …

Lifestyle Choices Related To Food Consumption And Their Relationship To Depression, Steven L. Jennings Jr.

Dissertations

Dieting, or the act of restricting oneself to small amounts or particular kinds of foods on the basis of health, spirituality, lifestyle, and moral decisions, is a practice that dates to 1066 A.D. However, with social media being as influential as it is, one might believe dieting is a new obsession or at least an obsession to which popular culture is returning. Despite this, it is only in recent years that researchers have begun to focus on the health benefits of such behaviors. The present study was designed to take this focus a step further by exploring the potential risks …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Risk Factors Of Cyberbullying Victimization: The Impact Of Developmental Trauma, Yuliya Mykytyn

Dissertations

Trauma has been considered as one of the significant causes of psychological distress, especially if the traumatic event occurred in the childhood. At the same time, due to wide popularity of social media as a source of communication, cyberbullying emerged as a new way to harass someone, with specific focus on adults and young adults. The area of focus of this research project is to investigate whether experienced trauma, specifically developmental trauma might serve as a risk factor for cyberbullying victimization. Additional focus was on the differences in traumatic experiences and their impact for people with diverse cultural and ethnic …

The Prevalence Of Mirror Gazing Behaviors In Men, Rutuja Pramod Chinchankar

Dissertations

Muscle Dysmorphia is when the individual is preoccupied with the idea that his or her body build is too small or insufficiently muscular. This study looked at the distinct criteria of MD, which is persistently and obsessively checking one’s appearance in the mirror and being dissatisfied with it. It studied the reasons behind these repetitive mirror-gazing behaviors. This study also attempted to understand the effect of an individual’s age, educational background, religious orientation, sexual orientation, and socio-economic status on his predisposition to MD via mirror-gazing behaviors. This study used a qualitative research design. Part I of the study included participants …

Generation Status, Ethnic Identity, Colonial Mentality, And Enculturation In Filipino Americans, Kamille Patricia Urmaza La Rosa

Dissertations

Filipino Americans’ psychological experiences pertaining to their generation status, ethnic identity, enculturation, and colonial mentality are rarely studied in counseling psychology due to inconsistent disaggregation of Asian American and Pacific Islander (AA&PI) data (Agbayani-Siewert, 2004; Espiritu, 2003; Nadal et al., 2010; Okamura, 2013). Literature suggests that the study of these constructs related to their mental health can guide more culturally informed care for this historically excluded population (David & Nadal, 2013; Nadal, 2020). The current study used an exploratory design to test six research hypotheses and accomplish the following: examine relationships between the constructs, investigate intergenerational differences, validate a measure …

The Influence Of Integrated Behavioral Health Primary Care Setting On The Utilization Of Mental Health Services And Depression Treatment Response Among Men, Tendai Masiriri

Dissertations

The 2010-2013 National Health Interview Survey showed that nearly 9% of men had daily feelings of anxiety or depression, yet less than 41% sought help for their symptoms (Blumberg et al., 2016). Men are more reluctant than women to seek help (Angst et al., 2002; Brownhill et al., 2005). The failure to seek help among men is associated with multiple factors related to stigma and gender, yet male suicide rates are approximately 3-5 times higher than their female counterparts. However, they have a higher likelihood of seeking help from a medical provider rather than a mental health provider. If men …

Mental Construal And Alterations In Emotional Memory, Olivia D. Beers

Dissertations

Psychological distancing refers to a shift from a psychologically immersed perspective that involves thinking about the details of an event (concretely) or stepping back from it and watching the event from an outside point of view (abstractly)––this can help individuals change how they feel about the experience. Investigating how construal levels affect emotional memories may provide more insight into how individuals may potentially alter the recall of their memories. The current study reflects a new examination of the effect of primed high and low construal levels on the recall of positive and negative arousing stimuli. This study included a pilot …

Mental Health Treatment In Juvenile Correctional Facilities: Utilizing Assessment To Inform Treatment, Sarah Riccio

Dissertations

Youth in juvenile correctional facilities face a wide range of mental health difficulties. Over the years, the juvenile justice system has prioritized the need for providing appropriate and effective treatment services to youth throughout their detainment. Despite these ongoing efforts, treatment practices in juvenile correctional facilities continue to fall short. This study will first focus on assessment practices within these facilities and the impact current practices have on diagnosis and subsequent treatment. Emphasis will be placed on the importance of comprehensive evaluations for informing diagnosis and determining the individual treatment needs of detained youth. An integrated approach to assessment will …

Preclinical Behavioral Assessment Of Chronic, Intermittent Low-Dose Psilocybin In Rodent Models Of Depression And Anxiety, Harmony I. Risca

Dissertations

Recent studies have demonstrated the clinical efficacy of psychedelic-assisted psychotherapy for treatment-resistant depression and anxiety. Amidst the overall success of recent clinical trials using a single high dose of psilocybin, anecdotal reports indicate anxiolytic and antidepressant effects following a repeated low dose regimen. As therapeutic outcomes are often tightly intertwined with the individual’s subjective experience, animal models are used as objective measures to investigate the underlying mechanisms responsible for the putative antidepressant/anxiolytic effects of psychedelics. Three rodent models predictive of anxiolytic or antidepressant effects were used to evaluate effects of chronic intermittent low dose (CILD) psilocybin treatment; the Light/Dark conflict …

Exploration Of Patient Variables And Characteristics Best Suited For Medical Marijuana Treatment For Anxiety And Depressive Disorders, Corey Gazoo

Dissertations

Individuals with posttraumatic stress, anxiety and depressive disorders are currently being prescribed medical marijuana as a treatment in many states across the United States. However, marijuana is still considered a schedule one narcotic by the Drug Enforcement Administration and federal government, which provides several barriers and challenges to conduct research such as approval from the U.S. Food and Drug Administration and following guidelines from the National Institute on Drug Abuse issued by the DEA. Additionally, individuals prescribed medical marijuana for mental health disorders are not always thoroughly instructed on the type of medical marijuana, the dosage, and how frequently to …

Examining Treatment Acceptability Of An Eight-Week Mindfulness-Based Stress Reduction Protocol, Blake William Palmer

Dissertations

The goal of this study is to examine whether levels of perceived stress, experiential avoidance, personality traits including openness to experience and agreeableness, and demographic variables will predict the treatment acceptability (indicated by responses on the Treatment Acceptability and Adherence Scale) of an eight-week Mindfulness-Based Stress Reduction (MBSR) program. This study collected data in the Spring of 2019. The final number of participants in the study was 116 (40 females, 76 males, Mage = 36, age range: 22-69 years). Participants completed measures including the Perceived Stress Scale (PSS), Acceptance and Action Questionnaire-II (AAQ-II), the agreeableness and openness to Experience domains …

Empowering Nurses Of Minority In The Face Of Incivility And Bullying: Through The Lens Of Phenomenology, Corrine Floyd

Dissertations

Abstract

Up to 85% of nurses have reported exposure to incivility in the workplace (Hunt & Marini, 2012). The often-subtle nature of incivility toward nurses in a minority population may partially explain why it remains a problem. Healthcare organizations realize the need for civility to counter the high turnover rate, staff shortages, and low job satisfaction reported by nurses, but lack understanding of how nurses of a minority population perceive incivility and bullying. This study aimed to answer the research question how do nurses with minority representation experience incivility and bullying versus empowerment in the workplace? A descriptive phenomenological design …

Bridging The Gap: Understanding Non-Offending Parental Responses To Their Children's Sexual Abuse., Jennifer Latreill, Psy.D.

Dissertations

The parental response to children's disclosure of childhood sexual abuse (CSA) is the most critical and important factor regarding the child's post trauma trajectory and overall trauma resolution. Understanding parental responses and the factors that prompt acceptance versus disbelief among the non-offending parent (NOP) is vital to children's success following disclosure given the weight of the NOPs response and its impact on long-term consequences of CSA. This literature review provides a comprehensive summary of what may deter the NOP from recognizing intrafamilial sexual abuse, factors that may contribute to the NOPs disbelief following disclosure, and possible clinical implications of such …

Exploration Of Physician Attitudes About Self-Care And Personal Mental Health: Possible Barriers To Physician Well Being, Candich Farrar

Dissertations

The present study was designed to examine physicians’ mental health, attitudes, and behaviors toward self-care and the utilization of mental health services. As the medical field can be very demanding and exhausting, it is believed that many physicians suffer from mental illnesses such as anxiety and depression. However, it was theorized that many physicians do not engage in adequate self-care regimes or seek support and suppress their symptoms, which may further exacerbate their illnesses. A thorough literature review was performed to explore the following: possible barriers to physicians seeking mental health services to address high rates of mental illnesses, physicians …

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran …

Indirect & Displaced Aggression: The Role Of Comparison Based Traits And Cognitive Vulnerabilities, Niki M. Knight

Dissertations

The present study explored the relationships of contingent self-esteem, dispositional envy, and two cognitive vulnerabilities (i.e., anger rumination and fear of negative evaluation) to indirect aggression (IA) and displaced aggression (DA) in a college student sample (N = 346). Despite the theoretical relevance of these personality and cognitive factors to aggression, there is little empirical evidence linking them to the perpetration of IA and DA. Bivariate correlations and hierarchical multiple regression were used to test the utility of these constructs in accounting for unique variance in IA and DA and to assess the potential role of participant gender. Participants …

Factors Affecting Mental Health Seeking Behaviors Of Law Enforcement Officers, Vincent M. Haecker

Dissertations

The intent of this study was to elicit perspectives from law enforcement counselors, clinicians, chaplains, and peer group leaders for factors affecting law enforcement officer’s (LEOs) seeking mental health assistance. The law enforcement and mental health communities have gone to great lengths to ensure assistance is available to LEOs in an effort to counter the stress and trauma associated with the policing profession. Past studies attempted to elicit LEOs attitudes on mental health services, generating mixed results and were unable to establish why available services were underutilized. This study employed a qualitative methodology to elicit perspectives on this phenomena from …

The Associations Among Expressed Emotion, Relationship Satisfaction, Ptsd Symptoms, Alcohol Use, And Depression: A Longitudinal Investigation With A Military Sample, Laci Lee Zawilinski

Dissertations

PTSD in military personnel is highly prevalent and accompanied by elevated rates of additional issues such as depression, problematic alcohol use, and interpersonal relationship problems. Family members and spouses of military personnel have also been shown to be negatively impacted by PTSD symptoms. Previous research has indicated that family members and spouses’ expressed emotion regarding the PTSD patients’ symptoms negatively impacts treatment outcome in civilian populations. However, studies have yet to investigate the effect of expressed emotion on the course of PTSD symptoms and associated problems in military personnel. Therefore, the purpose of the present investigation was to examine the …

Piloting A Screening Tool For Eating And Eating-Related Behavior, Michael N. Reynolds

Dissertations

Obesity is a common medical condition associated with negative health and social outcomes. Obesity has a primary malleable behavioral cause, eating more calories than are metabolized. While metabolic rate is malleable with exercise, eating can more quickly add calories than exercising can subtract them. In the past, behavioral weight-loss treatment studies relied on multi-component package interventions that have shown reliable patterns of participant weight-loss during treatment and weight-regain in follow-up. Those findings could be conceptualized as an ABA withdrawal design, eating behavior returns to baseline after the prosthetic contingencies of the treatment study are withdrawn. We must develop ways to …

Increasing Physical Activity In Young Adults With Autism Spectrum Disorder, Katherine B. Lalonde

Dissertations

Experts recommend that individuals walk 10,000 steps or more per day and doing so has been shown to have several health benefits. Unfortunately, many people fall short of 10,000 steps per day. Exercise levels are characteristically lower in people with Autism Spectrum Disorders (ASD) than in people without ASD. The present study comprised two experiments that used goal setting and reinforcement to increase physical activity in young adults with ASD. The first study employed a multiple-baseline-across-participants design in combination with a reversal design to determine the effects of a treatment package on the number of daily steps taken by young …

Impulsive Choice In Unmedicated And Medicated Children Diagnosed With Adhd: Examining The Variables Of Reward Type And Adhd Subtype, Nicole Henriksen

Dissertations

Developmentally inappropriate and impairing impulsive behaviors are often seen in attention-deficit/hyperactivity disorder (ADHD). One method for objectively assessing impulsivity is the Choice-Delay Task (C-DT) which presents repeated opportunities to choose between a smaller, sooner (SS) or larger, later (LL) reward. A preference for the SS reward that results in less total reward is considered impulsive. Many studies have found that participants diagnosed with ADHD choose the SS reward more than typical controls. However, less is known about the effects of different types of rewards, or the comparative performance of certain subgroups, such as children diagnosed with ADHD Predominantly Inattentive Type …

Evaluation Of Modafinil In Preclinical Behavioral Assays Of Abuse Liability, Amanda J. Quisenberry

Dissertations

Modafinil is an FDA-approved drug for the treatment of narcolepsy with efficacy in the treatment of chronic fatigue syndrome, obstructive sleep apnea, and shift-work sleep disorder. Modafinil’s wake-promoting and cognitiveenhancing effects are reportedly similar to those of traditional psychostimulants, but without the side effects typically associated with these substances. Modafinil has also been investigated as an agonist replacement therapy for psychostimulant dependence, although results of clinical trials are equivocal. Few studies have examined its behavioral effects in combination with psychostimulants and the neuropharmacological actions of modafinil are not well understood. The primary aim of this study was to assess modafinil’s …

Effectiveness Of A Motivational Enhancement Group Treatment In A Community Treatment Program With A Substance Abusing Population, Matthew S. Willerick

Dissertations

Motivational interviewing (MI) is a directive, client-centered intervention to elicit behavior change by assisting clients in the exploration and resolution of ambivalence toward change. MI-inspired approaches have been used in an attempt to facilitate change in a wide variety of domains including alcohol and drug abuse, safe water handling practices, dual diagnoses, gambling, spousal abuse, health related areas, mood and anxiety disorders, and parental engagement. MI seeks to resolve ambivalence in the direction of change by increasing the client's self-efficacy. This is accomplished by combining clientcentered (e.g., reflective listening) and directive strategies (e.g., attending selectively to change statements). The origins …

Dissertations

Idiosyncratic effects of Vyvanse™ (lisdexamfetamine dimesylate) and placebo were evaluated in a double-blind alternating treatments experimental design in this 4-week study. Direct, objective measures were combined with traditional behavior ratings to provide data sets to assess whether or not the prescribed stimulant medication showed detectable therapeutic effects for a child whose positive response to medication was not obvious via traditional subjective methods. Effects of medication on core ADHD symptoms, academic performance, and sleep in four children ages 10-12 with attention deficit/ hyperactivity disorder. Potential side effects were also measured. Daily measures included parent rating scales, side effects checklist, sleep journal …

An Investigation Of The Knowledge And Beliefs Held By Teachers And Parents In A Parochial School System Regarding Attention-Deficit/Hyperactivity Disorder And The Variables That Predict Their Knowledge, Kendra-Lee Yvonne Pearman

Dissertations

Problem

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent childhood disorders affecting 3 to 5% of school populations in the United States and other countries. Due to the behavioral and/or academic challenges of children with ADHD, they are at risk for grade retention, dropping out of high school, and teenage delinquency, which can lead to negative consequences in society. Children with ADHD are found in every school setting, including parochial schools. Past studies have found teachers and parents have inadequate knowledge about ADHD, which can negatively affect these children. This study investigated what teachers and parents of children in …
