Drinking-in-the-dark (DID): Mice given 20% ethanol 4-hours, 4-days/week x 3 weeks and then i.p. tideglusib or vehicle x 4 days in a Latin Square design with ethanol consumption measured daily. Light/Dark Box: Mice gavaged with tideglusib or vehicle …
Chronic Adolescent Stress As A Predictive Factor For The Risk Of Developing Ptsd-Like Symptoms In Adulthood, Grace K. Young
Chronic Adolescent Stress As A Predictive Factor For The Risk Of Developing Ptsd-Like Symptoms In Adulthood, Grace K. Young
Theses and Dissertations
Post-traumatic stress disorder is a stress and trauma based psychological disorder that is defined by the DSM-IV as an anxiety disorder that affects approximately 7.8% of people in the United States. PTSD is when those who suffer a traumatic event have intense and distressing feelings, emotions, and memories for a prolonged period of time after the event. A prominent feature of PTSD is the impaired ability to properly extinguish a fear response after a dangerous trigger or stressor is no longer present, also known as safety learning. Stressors are threats perceived within the environment that activate a response within the …
Impact Of The Covid-19 Pandemic On Child Anxiety Symptoms: The Influence Of The Caregiver-Child Relationship, Rebecca Hoppe
Impact Of The Covid-19 Pandemic On Child Anxiety Symptoms: The Influence Of The Caregiver-Child Relationship, Rebecca Hoppe
Theses and Dissertations
Research suggests that youth are dealing with a myriad of worries during the COVID-19 pandemic (Ellis et al., 2020), which highlights the need for investigations focused on child anxiety. However, to date little research has examined children’s anxiety in the COVID-19 pandemic nor the potential protective effects of the caregiver-child relationship. Therefore, this research aimed to contribute to the literature by investigating the influence of COVID-19 related stressors in younger children and leveraging children’s report of their own attachment security within their relationship with their caregiver and mental health. The current study used a national, quantitative survey of young children …

The Relationship Between Social Media Use And Depression And Anxiety Symptoms During Covid-19, Tene'sha L. Crews, Christina Sheerin
Undergraduate Research Posters
The rise of the coronavirus (COVID-19) pandemic has caused a global surge in exposure to disaster and crisis-related media. Increases in poor mental health outcomes such as anxiety and depression, are associated with increased exposure to such media content (Abbas et al., 2021; Riehm et al., 2020; Zhao & Zhou, 2020). In recent years, social media has become one of the most widely used sources for news; approximately 48% of adult Americans receive their news from social media (Pew Research Center, 2021). During the COVID-19 pandemic, there has been an increase in social media use due to social distancing and …
The Harm In Seeking Care: Assessing The Relationship Between Healthcare Discrimination And Healthcare Avoidance Behaviors In The Past Year And Since The Start Of The Coronavirus Pandemic In A Transgender And Gender Independent Sample, Kyle L. Mason
Theses and Dissertations
Background: Gender minorities encounter a myriad of barriers to accessing general and gender affirming healthcare. Financial disparities impacting affordability of healthcare costs and insurance-based denials for gender-affirming care are among prominent barriers discussed. Considerations of the prevalence of stigma, discrimination, and erasure of gender minority identities must not be neglected when seeking to understand healthcare accessibility and utilization in this population. Previous researchers have examined gender minority patients’ experiences of discrimination in healthcare settings and delaying care due to fear of discrimination. There is a dearth of knowledge about the relationship between lifetime exposure to varied forms of healthcare discrimination …

Psychiatry Publications
Background: Laboratory-based research with community samples has suggested changes in affective, behavioural and cognitive processes as possible explanations for the effects of serotonergic medications. Examining the effects of serotonergic medications using an ecological momentary measure (such as event-contingent recording) in the daily lives of people with social anxiety disorder would contribute to establishing the effects of these medications on affect, behaviour and one form of cognition: perception of others’ behaviour.
Methods: The present study assessed changes in affect, interpersonal behaviour and perception of others’ behaviour in adults with social anxiety disorder using ecological momentary assessment at baseline and over 4 …
Anxious?: Re-Designing Women’S Jewelry To Help Manage Symptoms Of Anxiety Disorders, Nourbanu Feras Hijazi
Anxious?: Re-Designing Women’S Jewelry To Help Manage Symptoms Of Anxiety Disorders, Nourbanu Feras Hijazi
Theses and Dissertations
Anxiety is a common and often stigmatized condition. Destigmatizing mental disorders can positively impact people’s interaction and communication with others and can prompt conversations in which people share their experiences with mental health, leading to improved societal understanding and perception.
My design solution tackles behavioral symptoms of anxiety, specifically two conditions that fall under obsessive-compulsive behavior: Dermatillomania and Trichotillomania. By redesigning women’s jewelry to specialized accessories, my intention is for these objects to help destigmatize these conditions and relieve symptoms of maladaptive behaviors and hurtful impulses. By redirecting these irresistible urges to an external artifact, the objects are designed to …
Impact Of Chemotherapy On Nicotine Dependence, Yasmin Alkhlaif
Impact Of Chemotherapy On Nicotine Dependence, Yasmin Alkhlaif
Theses and Dissertations
Although cigarette smoke has been implicated in a causal relationship with various types of cancers, around 62% of all cancer patients are current smokers, recent quitters, or former smokers. While most patients who are smokers are motivated to quit after cancer diagnosis, 25 -30% of these patients continue to smoke. Furthermore, most quitters relapse after 2-3 years of post-chemotherapy. This represents a major health concern since several clinical studies revealed that perpetuation of smoking in cancer populations attenuates patient's well-being and quality of life. Smoking may impair healing, attenuate the efficacy of chemotherapy, increase the disease complications and diminish survival …
Repeated Low-Dose Organophosphate Dfp Exposure Leads To The Development Of Depression And Cognitive Impairment In A Rat Model Of Gulf War Illness, Laxmikant Deshpande, Kristin Phillips
Repeated Low-Dose Organophosphate Dfp Exposure Leads To The Development Of Depression And Cognitive Impairment In A Rat Model Of Gulf War Illness, Laxmikant Deshpande, Kristin Phillips
Neurology Publications
Approximately 175,000 to 250,000 of the returning veterans from the 1991 Persian Gulf War exhibit chronic multi-symptom illnesses that includes neurologic co-morbidities such as depression, anxiety and cognitive impairments. Amongst a host of causative factors, exposure to low levels of the nerve agent Sarin has been strongly implicated for expression of Gulf War Illness (GWI). Nerve agents similar to pesticides are organophosphate (OP) compounds. There is evidence from civilian population that exposure to OPs such as in agricultural workers and nerve agents such as the survivors and first-responders of the Tokyo subway Sarin gas attack suffer from chronic neurological problems …

Identifying Molecular Features Associated With Psychoneurological Symptoms In Women With Breast Cancer Using Multivariate Mixed Models, Qing Zhou, Colleen Jackson-Cook, Debra Lyon, Robert Perera, Kellie Archer
Biostatistics Publications
Breast cancer (BC) is the second most common cancer among women. Research shows many women with BC experience anxiety, depression, and stress (ADS). Epigenetics has recently emerged as a potential mechanism for the development of depression.1 Although there are growing numbers of research studies indicating that epigenetic changes are associated with ADS, there is currently no evidence that this association is present in women with BC. The goal of this study was to identify high-throughput methylation sites (CpG sites) that are associated with three psychoneurological symptoms (ADS) in women with BC. Traditionally, univariate models have been used to examine …
Asthma-Related Anxiety And Quick-Relief Medication Use In Urban Children With Asthma, Sarah E. Astrab, Robin Everhart
Asthma-Related Anxiety And Quick-Relief Medication Use In Urban Children With Asthma, Sarah E. Astrab, Robin Everhart
Undergraduate Research Posters
Among children, asthma is the most common chronic illness. Although not curable, asthma is manageable with the use of both daily controller medication and quick relief or rescue medication. Anxiety has been found to increase asthma symptoms in children. Caregivers who are anxious about their child’s asthma symptoms may perceive their child’s asthma as more severe or doubt their ability to manage their child’s asthma, which can result in the misuse of asthma medication. This study focused on the association between asthma-related anxiety and the use of quick-relief asthma medications in a low-income, urban sample in Richmond, Virginia. Child participants …
Chronic Behavioral And Cognitive Deficits In A Rat Survival Model Of Paraoxon Toxicity, Laxmikant Sudhir Deshpande, Kristin Phillips, Beverly Huang, Robert J. Delorenzo
Chronic Behavioral And Cognitive Deficits In A Rat Survival Model Of Paraoxon Toxicity, Laxmikant Sudhir Deshpande, Kristin Phillips, Beverly Huang, Robert J. Delorenzo
Neurology Publications
Organophosphate (OP) compounds, including paraoxon (POX), are similar to nerve agents such as sarin. There is a growing concern that OP agents could be weaponized to cause mass civilian causalities. We have developed a rodent survival model of POX toxicity that is being used to evaluate chronic morbidity and to screen for medical countermeasures against severe OP exposure. It is well known that the survivors of nerve gas and chronic OP exposure exhibit neurobehavioral deficits such as mood changes, depression, and memory impairments. In this study we investigated whether animals surviving severe POX exposure exhibited long-term neurological impairments. POX exposure …
Follow-Up Evaluation Of Treatment For Anxiety And Depression Provided In A University-Based Primary Care Clinic, Renée M. Grinnell
Follow-Up Evaluation Of Treatment For Anxiety And Depression Provided In A University-Based Primary Care Clinic, Renée M. Grinnell
Theses and Dissertations
Although integrated primary care psychology services are becoming increasingly common, the literature lacks adequate research support for the longitudinal durability of treatment effects following the conclusion of brief primary care interventions. This study served as a follow-up program evaluation of psychological services for depression and anxiety provided at the Medical College of Virginia’s Ambulatory Care Center in Richmond, Virginia. Data were collected on 47 adult primary care patients who received treatment for depression and/or anxiety between six and 18 months prior to the follow-up telephone call. Data were collected on the trajectory of depression scores throughout and following treatment, treatment …
Beta 2 Nicotinic Acetylcholine Receptor Contributions To Anxiety-Like Behavior, Shawn Anderson
Beta 2 Nicotinic Acetylcholine Receptor Contributions To Anxiety-Like Behavior, Shawn Anderson
Theses and Dissertations
Nicotine is a major psychoactive ingredient in tobacco that is thought to promote smoking behavior via nicotinic acetylcholine receptors (nAChRs) in the brain. Given reports that people smoke to relieve anxiety and that anxiety precipitates relapse, the overarching goal of this dissertation research is to assess beta 2 subunit containing nAChR (beta2*nAChR) contributions to anxiety-like behavior. Nicotine’s activity at beta2*nAChRs is concentration-dependent, with high concentrations facilitating activation followed by rapid desensitization and low concentrations preferentially desensitizing beta2*nAChRs; hence, activation or inhibition of beta2*nAChRs may support smoking behavior. Rodent studies reveal that nicotine affects anxiety-like behavior dose-dependently: low doses promote anxiolysis- …
Genetic Dissection Of Quantitative Trait Loci For Substances Of Abuse, Jo Lynne Harenza
Genetic Dissection Of Quantitative Trait Loci For Substances Of Abuse, Jo Lynne Harenza
Theses and Dissertations
It has been reported that an individual’s initial level of response to a drug might be predictive of his or her future risk of becoming dependent, thus basal gene expression profiles underlying those drug responses may be informative for both predicting addiction susceptibility and determining targets for intervention. This dissertation research aims to elucidate genetic risk factors underlying acute alcohol and nicotine dependence phenotypes using mouse genetic models of addiction. Phenotyping, brain region-specific mRNA expression profiling, and genetic mapping of a recombinant inbred panel of over 25 mouse strains were performed in order to identify quantitative trait loci (QTL) harboring …

On The Genetic And Environmental Associations Between Body Composition, Depression Symptoms And Smoking Behavior., Roseann Peterson
Theses and Dissertations
Obesity is a serious public health crisis and recent estimates of its incidence are the highest in United States history, with 35% and 17% of American adults and children affected, respectively. The clinical definition of adult obesity is operationalized as a body mass index (BMI) greater than 30 kg/m2. Although the prevalence of common obesity has increased dramatically over the past 30 years–largely thought to be due to changes in the environment, such as high calorie diets and sedentary lifestyles—twin and family studies have shown consistently that relative body weight is under considerable genetic influence in both children and adults, …

The Role Of High Affinity Nicotinic Acetylcholine Receptors On Anxiety-Like Behavior: A Study In Female Mice, Jessicka Hall
The Role Of High Affinity Nicotinic Acetylcholine Receptors On Anxiety-Like Behavior: A Study In Female Mice, Jessicka Hall
Theses and Dissertations
Tobacco dependence is high in women who suffer from anxiety disorders yet little is known about the contributions of nicotinic acetylcholine receptors (nAChRs) on anxiety-like behavior. β2*nAChRs (*denotes assembly with other subunits) are the most abundantly expressed nAChRs in the brain yet little is known about the contributions of β2*nAChRs on anxiety-like behavior in female mice. In this study, antagonism and nicotine effects on anxiety-like behavior was investigated across the life span in 6, 12 and 24-month-old drug-naïve knockout (KO), heterozygous (HET) and a gain of function α6L9S mice and wild type (WT). HET mice showed increased sensitivity to di-hydrobeta-erythroidine …
Stress And Anxiety In Adhd: Links To Sensory Over-Responsivity, Stacey E. Reynolds
Stress And Anxiety In Adhd: Links To Sensory Over-Responsivity, Stacey E. Reynolds
Theses and Dissertations
Sensory Modulation Dysfunction (SMD) is characterized by an inability to consistently and accurately grade responses to sensory information. SMD, and specifically sensory over-responsivity (SOR), has been correlated with stress and anxiety in some developmentally delayed populations and has been associated with structures and functions of the hypothalamic-pituitary adrenal (HPA) axis. Recent attention has been given to HPA functioning in children with Attention Deficit Hyperactivity Disorder (ADHD), with a majority of studies identifying blunted or diminished cortisol patterns. In contrast, elevated cortisol has been associated with anxiety and anxious behaviors in both animal and human studies. The purpose of this study …

The Effects Of Footshock On The Reinforcing Efficacy Of Cocaine In Male Long-Evans Rats, Elizabeth S. Hendrick
The Effects Of Footshock On The Reinforcing Efficacy Of Cocaine In Male Long-Evans Rats, Elizabeth S. Hendrick
Theses and Dissertations
Many links exist between cocaine abuse and stress. The literature and laboratory studies in rats suggest that this could be because stress increases the reinforcing efficacy of cocaine. Using male Long-Evans rats, experiments in this thesis tested effects of footshock on the reinforcing efficacy of cocaine using a progressive ratio schedule of reinforcement. They also examined effects of footshock on the reinforcing efficacy of a half-maximal dose of cocaine. Finally, they tested the effects of footshock on cocaine self-administration in rats initially resistant to acquisition of cocaine self-administration. Footshock did not increase reinforcing efficacy of cocaine on a PR schedule …
Recognition And Management Of Psychiatric Emergencies, John A. Ewing
Recognition And Management Of Psychiatric Emergencies, John A. Ewing
MCV/Q, Medical College of Virginia Quarterly
Emergencies are simply unforeseen occurrences which present themselves to physicians in a variety of ways. Indeed, a physician is not the first person on hand for most emergencies but may merely be called upon for appropriate intervention. Any of us can be presented with an emergency, psychiatric or otherwise, at any moment. However, each of us has his own particular probability of sampling psychiatric emergencies, depending upon who he is and what he does. In actual fact, psychiatric emergencies more often confront people other than psychiatrists, for example, the policeman, the social worker, and the general practitioner (Ewing, 1965). As …
Physical Illness: The Family And The Physician, Marc H. Hollender
Physical Illness: The Family And The Physician, Marc H. Hollender
MCV/Q, Medical College of Virginia Quarterly
When confronted by the specific stress of a close relative's illness, the family members' reactions may be schematically divided into three stages: 1) disorganization; 2) reintegration; and 3) adjustment. Either disorganization can be intensified or adjustment can be fostered, depending on the physician's understanding of the feelings the family members experience and his willingness and ability to be helpful. The family members' responses, in turn, will influence the patient's reaction to illness or his recovery and rehabilitation. Accordingly, good medical practice requires that the physician include the family in his total treatment plan whenever possible.
Anxiety, Defense And Cognition: A Theoretical Basis For Practical Handling Of The Surgical Patient, Stanley L. Block
Anxiety, Defense And Cognition: A Theoretical Basis For Practical Handling Of The Surgical Patient, Stanley L. Block
MCV/Q, Medical College of Virginia Quarterly
Both the anxiety-defense model and the cognitive model provide a scientific basis for practical handling of the surgical patient. Emerging from both models is a humanistic approach to the patient based on understanding and a nonjudgmental attitude as well as on a knowledge of where the patient is psychologically and a willingness to meet him on his ground. The rewards in terms of a reduction of anxiety, depression, and human suffering can be enormous.
The Treatment Of Anxiety, John J. Schwab, Nancy H. Mcginnis
The Treatment Of Anxiety, John J. Schwab, Nancy H. Mcginnis
MCV/Q, Medical College of Virginia Quarterly
Rational therapy requires accurate diagnosis. When we apply this precept to anxiety a fundamental question arises. Is anxiety an illness in terms of the now berated medical model which holds that an illness has a cause, a natural history, and hopefully a cure? Or is anxiety a basic aspect of the human condition, an innate pattern of response which becomes pathological when stress, induced by physiologic and social forces, is magnified out of proportion to the original stimulus? If the latter is true, then stress and social interactions are the causative factors, the anxiety only a reaction. Logically then, the …
