Family-Based Support As Social Determinants Of Health Protective Factor On Depression Of Parents Of Children With Autism Spectrum Disorder, Bisola E. Duyile
Family-Based Support As Social Determinants Of Health Protective Factor On Depression Of Parents Of Children With Autism Spectrum Disorder, Bisola E. Duyile
Theses and Dissertations
All parents experience challenges in their caregiving roles (Barańczuk & Pisula, 2020). However, parents raising a child/children with disabilities experience different social barriers (Oliver, 1996) that may also contribute to additional stressors in their caregiving role (Tomeny, 2016). Although these parents, on average, have reported greater symptoms of depression than parents of typically developing children, research shows that parents who reported receiving social support had lower symptoms of depression and stress (Das et al., 2017; Singh et al., 2017). Through the social determinants of health (SDOH) framework (ODPHP, 2022), the present study investigated informal/family-based support and its protective impact on …
Examining Ayahuasca Constituents At 5-Ht2a Receptors In Search Of Antidepressant Action, Jeremy D. Rolquin
Examining Ayahuasca Constituents At 5-Ht2a Receptors In Search Of Antidepressant Action, Jeremy D. Rolquin
Theses and Dissertations
Recently, it has been reported that ligands of the 5-HT2A receptor can have drastic and fast-acting efficacy towards a number of different mental health disorders, such as depression and anxiety. A mixture of Amazonian plants calledayahuasca contains multiple compounds which have been shown to interact with the serotonergic system, and the 5-HT2Areceptor in particular.
The structurally similar compounds (DMT, harmine, harmaline, and tetrahydroharmine) found in ayahuasca were examined for differences in their physiochemical properties that might contribute to their binding affinity for the 5-HT2Areceptor. 3D Molecular modeling and docking studies of these compounds were …
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 …
The Correlation Between Maternal Postpartum Depression And Child Psychopathology, T'Keyah I. Vaughan
The Correlation Between Maternal Postpartum Depression And Child Psychopathology, T'Keyah I. Vaughan
Theses and Dissertations
Background: Postpartum depression (PPD) is a phenomenon that affects nearly 10-15% of pregnancies in the US. It is characterized by depressed mood or anhedonia and lasting for more than 2 weeks. PPD changes how moms interact with family members and child-rearing behavior. Depression is a phenomenon that is also known to affect the psychopathology of children. However, the specifics of how postpartum depression impacts children remains controversial. Many studies do not control for major depressive disorder which makes it difficult to disentangle the impact depression has within the first year of life. Furthermore, other PPD risk factors may be confounding …
Perceived Stress, Salivary Cortisol, And Depression In Adults Diagnosed With Postconcussion Syndrome; A Pilot Study, Christine Fish-Huson
Perceived Stress, Salivary Cortisol, And Depression In Adults Diagnosed With Postconcussion Syndrome; A Pilot Study, Christine Fish-Huson
Theses and Dissertations
Traumatic Brain Injury (TBI) affects approximately 1.7 million persons in the United States annually, 75% are categorized as mild (mTBI). Most persons who experience mTBI will recover, however an estimated 10% will develop Postconcussion Syndrome (PCS). Evidence supports a relationship between perceived stress, salivary cortisol, and depressive symptoms in persons after TBI; however, there are no known studies exploring these relationships in the PCS patient population. A sample of 17 men and women diagnosed with PCS were recruited from Southwest and Central Virginia. Data collection included the Rivermead Postconcussion Questionnaire, Perceived Stress Scale-10, Center for Epidemiological Studies-Depression Scale and the …
Sleep Disturbances And Depression: The Role Of Genes And Trauma, Mackenzie J. Lind
Sleep Disturbances And Depression: The Role Of Genes And Trauma, Mackenzie J. Lind
Theses and Dissertations
Sleep disturbances and insomnia are prevalent, with around 33% of adults indicating that they experience at least one main symptom of insomnia, and bidirectional relationships exist with common psychopathology, particularly major depressive disorder (MDD). However, genetic and environmental (e.g., traumatic event exposure) contributions to the etiology of these phenotypes are not yet well understood. A genetically informative sample of approximately 12,000 Han Chinese women aged 30-60 (50% with recurrent MDD) was used to address several gaps within the sleep literature. Sleep disturbances were assessed in all individuals using a general item addressing sleeplessness (GS). A sleep within depression sum score …
Investigation On Genetic Modifiers Of Age At Onset Of Major Depressive Disorder, Huseyin Gedik
Investigation On Genetic Modifiers Of Age At Onset Of Major Depressive Disorder, Huseyin Gedik
Theses and Dissertations
Major Depressive Disorder (MDD) is a complex multifactorial disorder, which would lead to disability. Environmental and genetic factors are involved in MDD etiology. The aim of this project was to identify loci modifying age at onset (AAO) of MDD using survival models after adjusting for Childhood Sexual Abuse (CSA). To achieve this aim, a dataset was made available by the China Oxford and VCU Experimental Research on Genetic Epidemiology (CONVERGE) consortium. The study population had 5,220 controls and 5,282 cases with MDD. We performed two univariate association analyses using Cox Proportional Hazard (Cox PH) models. These two are Full Sample …
Depressive Symptoms Among College Students: An Exploration Of Fundamental Cause Theory, Peter A. Carrico
Depressive Symptoms Among College Students: An Exploration Of Fundamental Cause Theory, Peter A. Carrico
Theses and Dissertations
Fundamental Cause Theory suggests that socioeconomic and demographic factors are causal to various illnesses, including depression. However, no known previously existing research has used Fundamental Cause Theory to create a model of depression among college students. To do this, the present study conducted a stepwise binomial logistic regression to examine how socioeconomic status and the sociodemographic variables of Gender, Race, and Sexual Orientation, and others predict depressive symptoms in a large sample of undergraduates when controlling for stressful life events and social support (N = 2,915). Results support the hypothesis that socioeconomic disparities in depressive symptoms are the result …
Exploring The Concept Of Human Oct3 Inhibitors As A Novel Class Of Antidepressants, Kavita A. Iyer
Exploring The Concept Of Human Oct3 Inhibitors As A Novel Class Of Antidepressants, Kavita A. Iyer
Theses and Dissertations
The Dukat laboratory developed 2-amino-6-chloro-3,4-dihydroquinazoline (A6CDQ) as a 5-HT3 receptor ligand. A6CDQ and one of its positional isomers, the 7-chloro analog A7CDQ, produced antidepressant-like effects in the mouse tail suspension test (TST). We investigated and systematically ruled out a solely 5-HT3 receptor or hSERT mediated mechanism of antidepressant-like effect for both A6CDQ and A7CDQ.
The role of organic cation transporter 3 (OCT3) as an alternative mechanism in the regulation of neurotransmitters including serotonin (5-HT) and the therapeutic potential of targeting hOCT3 to achieve antidepressant effects has been established. By virtue of possessing protonatable nitrogen atoms, 2-aminodihyroquinazolines could potentially …
Behaviorally Induced Insufficient Sleep Syndrome And Insomnia: Prevalence And Relationship To Depression In College Students, Allison Baylor
Behaviorally Induced Insufficient Sleep Syndrome And Insomnia: Prevalence And Relationship To Depression In College Students, Allison Baylor
Theses and Dissertations
Background: College students are at increased risk for general sleep issues as well as specific disorders, including Behaviorally Induced Insufficient Sleep Syndrome (BISS) and insomnia. These disorders can have deleterious daytime consequences, which can be compounded by exacerbating depression. The present study aims to establish college prevalence of BISS/insomnia, to characterize sleep characteristics in this sample, and to compare depression across BISS/insomnia.
Methods: Data from a college risk behaviors and health study (n=989) was used. Insomnia and BISS were defined as mutually exclusive disorders, using ICD-10/DSM-5 criteria, and Pittsburg Sleep Quality Index items.
Results: Overall, the results of this study …
Chronic Behavioral And Cognitive Deficits In A Rat Survival Model Of Organophosphate Toxicity, Beverly Huang
Chronic Behavioral And Cognitive Deficits In A Rat Survival Model Of Organophosphate Toxicity, Beverly Huang
Theses and Dissertations
Organophosphates (OPs) are a major class of pesticides and nerve agents that elicit acute toxicity by inhibiting acetylcholinesterase (AChE), the enzyme responsible for the degradation of the neurotransmitter acetylcholine in the central and peripheral nervous systems. Acetylcholine accumulation following extensive AChE inhibition leads to an acute cholinergic syndrome characterized by autonomic dysfunction, involuntary movements, muscle fasciculations, respiratory distress, and seizures. Despite their classification as moderate to highly toxic, OP pesticides are the most widely used class of insecticides in the U.S., and are even more commonly used worldwide. Additionally, there is a growing concern that OP nerve agents could be …
Frailty And Depression: A Latent Trait Analysis, Matthew Lohman
Frailty And Depression: A Latent Trait Analysis, Matthew Lohman
Theses and Dissertations
Background: Frailty, a state indicating vulnerability to poor health outcomes, is a common condition in later life. However, research and intervention progress is hindered by the current lack of a consensus frailty definition and poor understanding of relationships between frailty and depression. Objectives: The goal of this research is to understand the interrelationships between frailty and depression among older adults. Specifically, this project aims 1) to examine the construct overlap between depression and three definitions of frailty (biological syndrome, medical burdens, and functional domains), 2) to determine the degree to which this overlap varies by age, gender, race/ethnicity and other …
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 …
Association Between Concomitant Use Of Bisphosphonates And Serotonin Reuptake Inhibitors And Increased Risk Of Osteoporotic-Related Fractures: Among Community-Dwelling Postmenopausal Women, Abner Nyandege
Theses and Dissertations
Osteoporosis and depression are prevalent among older postmenopausal women 65 years or older. Bisphosphonates (BPs) and selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) are commonly used medications to treat these conditions. Inhibitory effects of BPs on osteoclasts are responsible for the reduction in fracture risk. SSRIs, however, are associated with increased fracture risk through decreasing osteoblasts and increasing osteoclastic activity. These effects of SSRIs could attenuate the beneficial effects of BPs. This dissertation describes the concomitant use of BPs and SSRIs among postmeopausa women and reports findings from examining the association between concomitant use of BPs …
On The Genetic And Environmental Associations Between Body Composition, Depression Symptoms And Smoking Behavior., Roseann Peterson
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 Relationship Between Treatment-Seeking And Characteristics Of Depression Among African Americans, Tamara Scott
The Relationship Between Treatment-Seeking And Characteristics Of Depression Among African Americans, Tamara Scott
Theses and Dissertations
Objective: Depression is a common psychiatric condition, and despite the availability of effective treatments, this condition is largely under-recognized and undertreated, particularly among African Americans. One reason for this discrepancy may be that depressive symptoms often co-occur with physical health conditions, which can influence both the reporting of depressive symptomology, willingness to seek care, and the type of healthcare provider sought. The purpose of this study was to explore the relationship between treatment-seeking characteristics and diagnostic attributions of depression among community-dwelling African American adults. Methods: Data come from the National Survey of American Life, a nationally representative sample of African …

Theses and Dissertations
Introduction: Obesity is one of the most important medical problems in the U.S. and is considered to be an epidemic with over 30% of the population being obese. Obesity is associated with increased risk of hypertension, diabetes, cardiovascular diseases, certain cancers and a shorter life expectancy. Recent studies have shown that higher BMI levels are also significantly associated with several lifetime mental disorders such as major depressive disorder, anxiety disorders as well as panic attacks and panic disorders. Purpose: The purpose of this study was to quantify the extent to which higher BMI increased the likelihood of Depression, Anxiety Disorder …
Novel Analogs Of M-Chlorophenylguanidine As 5-Ht3 Receptor Ligands, Katie Alix
Novel Analogs Of M-Chlorophenylguanidine As 5-Ht3 Receptor Ligands, Katie Alix
Theses and Dissertations
Serotonin receptors play a variety of functional roles in the body. Some indications and treatment claims for one of the classes of serotonin receptors, the 5-HT3 receptor family, include: anxiety, depression, chemotherapy- and radiation-induced emesis, constipation, irritable bowel syndrome, pain, drug addiction, and satiety control. A 5-HT3 receptor partial agonist, MD-354, served as a lead compound in the development of new 5-HT3 receptor ligands. Using halogenated analogs the study investigated their effect on binding to the 5-HT3 receptor. Conformationally-constrained analogs (quinazolines) were shown to be a novel class of 5-HT3 receptor antagonists. The log P values were determined for several …

Veteran status and a host of demographic and health status questions were analyzed in relation to diagnosis of anxiety or depressive disorder (multiple logistic regression) and to number of days poor mental health (multiple linear regression). Results: Diagnosis of anxiety or depression was …
A Twin Study Of Antisocial Behavior And Depression: Methodology, Etiology, And Comorbidity, Kelly A. Tracy
A Twin Study Of Antisocial Behavior And Depression: Methodology, Etiology, And Comorbidity, Kelly A. Tracy
Theses and Dissertations
The etiological connection between internalizing and externalizing disorders is poorly understood. This manuscript aims to investigate the roles of genes and then environment in the development of Major Depressive Disorder (MDD) and Antisocial Personality Disorder (ASPD) and the nature of their comorbidity in young adults. Data from a sample of 2,291 young adult male and female twins from the Young Adult Follow Up Study (YAFU) of the Virginia Twin Study of Adolescent Behavioral Development (VTSABD) were used to estimate the proportion of variation in these traits that can be accounted for by additive genetic, shared environmental, and unique environmental factors. …
