Generalized Anxiety Disorder Symptoms Stratified By Age In Primary Care, Robin E. Mccoy

Walden Dissertations and Doctoral Studies

Little is known as to the age-related presentation of somatic complaints of those diagnosed with generalized anxiety disorder in primary care settings. A retrospective medical records review sought to identify the affective symptoms of generalized anxiety disorder (GAD) by age as recorded by primary care providers and to test the association of these symptoms by age. Guided by Engle’s (1977) biopsychosocial (BPS) model, a large administrative claim database system was used to derive a sample of 1,336, including 500 patients diagnosed with generalized anxiety disorder between 2018 to 2021. Binary logistics regression, one-way ANOVA, chi-square, correlation, and logistical regression with …


The Essence Of Therapeutic Relationships In Equine-Assisted Psychotherapy, Joy Clark Akin Jan 2023

The Essence Of Therapeutic Relationships In Equine-Assisted Psychotherapy, Joy Clark Akin

Walden Dissertations and Doctoral Studies

AbstractTraditional psychotherapeutic approaches are not always effective in alleviating psychological symptoms and improving functioning in young adults.

The Relationship Between Loneliness And Experiential Avoidance After Implementation Of A Self-Compassion Intervention, Alyssa Mielock Jan 2023

The Relationship Between Loneliness And Experiential Avoidance After Implementation Of A Self-Compassion Intervention, Alyssa Mielock

Graduate Research Theses & Dissertations

An individual’s perception of a social relationship is distinct from an individual’s difficulty forming and maintaining social relationships. Loneliness is defined as an individual’s distress resulting from the discrepancy between perceived and desired social relationship quality. In the short term, loneliness may act as a motivator for an individual to seek social support to minimize distress. However, long-term loneliness is associated with physical and psychological impairments. There have been several risk factors identified that contribute to chronic loneliness, such as social isolation, psychopathology, and ineffective coping strategies. Ineffective coping may be one mechanism by which loneliness is associated with psychopathology …

Implementation Of A Death Anxiety Screening Protocol Specific To Patients With Advanced Cancer In An Outpatient Palliative Care Setting, Olivia M. Sasdi Jan 2023

Implementation Of A Death Anxiety Screening Protocol Specific To Patients With Advanced Cancer In An Outpatient Palliative Care Setting, Olivia M. Sasdi

DNP Projects

Abstract

Background: Recent studies have shown that upwards of 80% of patients with advanced cancer suffer from death anxiety resulting in increased physical and psychological suffering. Despite death anxiety’s ubiquitous nature and negative impact, the literature regarding this condition consistently indicates that it remains under-identified and undertreated in patients with advanced cancer. The “Death and Dying Distress Scale” (DADDS) is a clinically validated tool used to identify, measure, and guide effective treatment modalities for death anxiety specifically in patients with advanced cancer, but is scarcely used routinely in practice. Incorporating this screening tool to be used regularly could improve identification …

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 …

Faculty, Staff and Student Publications

In late 2019, the emergence of COVID-19 in Wuhan, China, led to the implementation of stringent measures forming the zero-COVID policy aimed at eliminating transmission. Zero-COVID policy basically aimed at completely eliminating the transmission of COVID-19. However, the relaxation of this policy in late 2022 reportedly resulted in a rapid surge of COVID-19 cases. The aim of this work is to investigate the factors contributing to this outbreak using a new SEIR-type epidemic model with time-dependent level of immunity. Our model incorporates a time-dependent level of immunity considering vaccine doses administered and time-post-vaccination dependent vaccine efficacy. We find that vaccine …
