Does Decentering Mediate The Relationship Between Mindfulness And Stress And Anxiety?, Hana Hannah Lee Sep 2021

Does Decentering Mediate The Relationship Between Mindfulness And Stress And Anxiety?, Hana Hannah Lee

Theses and Dissertations

College students are stressed and unsuccessful efforts to cope can increase risk for poor mental health, including anxiety (American College Health, 2019). Research suggests mindfulness (Bamber & Schneider, 2016) and adaptive emotion regulation (Desrosiers et al. 2013b) can buffer against the deleterious effects of distress. Decentering, a mindful emotion regulation strategy (Chambers et al., 2009), is postulated to be a mechanism by which mindfulness can lead to better mental health (Shapiro et al. 2006). Specific facets of trait mindfulness, namely Nonjudging (NJ) and Nonreactivity (NR) (Mizera et al. 2016), are directly involved in regulating one's emotions, which can help reduce …


Neural Substrates Of Fear Generalization And Its Associations With Anxiety And Intolerance Of Uncertainty, Ashley Ann Huggins Aug 2021

Neural Substrates Of Fear Generalization And Its Associations With Anxiety And Intolerance Of Uncertainty, Ashley Ann Huggins

Theses and Dissertations

Fear generalization - the tendency to interpret ambiguous stimuli as threatening due to perceptual similarity to a learned threat – is an adaptive process. Overgeneralization, however, is maladaptive and has been implicated in a number of anxiety disorders. Neuroimaging research has indicated several regions sensitive to effects of generalization, including regions involved in fear excitation (e.g., amygdala, insula) and inhibition (e.g., ventromedial prefrontal cortex). Research has suggested several other small brain regions may play an important role in this process (e.g., hippocampal subfields, bed nucleus of the stria terminalis [BNST], habenula), but, to date, these regions have not been examined …


Comparing The Effects Of Noncontingent Reinforcement And Environmental Enrichment On Problem Behavior Maintained By Automatic Reinforcement, Mary Llinas Jul 2021

Comparing The Effects Of Noncontingent Reinforcement And Environmental Enrichment On Problem Behavior Maintained By Automatic Reinforcement, Mary Llinas

Theses and Dissertations

Environmental enrichment (EE) and noncontingent reinforcement (NCR) are common behavior analytic interventions used to decrease problem behavior maintained by automatic reinforcement. Both EE and NCR involve noncontingent access to preferred or competing stimuli, however, access to stimuli is intermittent (typically on a fixed-time [FT] schedule) in NCR, while in EE, the stimuli are continuously available. Despite the research on their effectiveness at reducing problem behavior, they have not been compared. The purpose of the current study was to compare the effectiveness of different schedules of reinforcement at decreasing automatically maintained problem behavior (stereotypy) and anxiety exhibited by two children with …


Characterizing Anxiety And Physiological Correlates In Preschool Children With Neurodevelopmental Disabilities, Jordan Ezell Jul 2021

Characterizing Anxiety And Physiological Correlates In Preschool Children With Neurodevelopmental Disabilities, Jordan Ezell

Theses and Dissertations

This dissertation is comprised of two original research manuscripts broadly examining anxiety and potential correlates in young children with neurodevelopmental disabilities. The first manuscript assessed cardiac regulation during an auditory startle paradigm in young children (3-6 years old) with autism spectrum disorder (ASD), fragile x syndrome (FXS), and neurotypical peers. The second manuscript utilized a new measure developed to capture anxiety in individuals with ASD in order to assess the rate of typical and atypical anxiety and potential risk factors (ASD severity, sex, cognitive ability) for anxiety in preschool children with ASD contrasted to neurotypical preschool children. Collectively, these two …


Behavioral, Physiological, And Molecular Characterization Of Long-Term Administration Of A Novel Estrogen Receptor Beta Agonist In A Mouse Model Of Menopause, Aaron William Fleischer May 2021

Behavioral, Physiological, And Molecular Characterization Of Long-Term Administration Of A Novel Estrogen Receptor Beta Agonist In A Mouse Model Of Menopause, Aaron William Fleischer

Theses and Dissertations

The menopausal loss of circulating hormones, including estrogens, is associated with negative symptoms, such as hot flashes, anxiety and depression, cognitive decline, and weight gain. Although estrogenic hormone therapies (HT) prevent many of the negative symptoms related to the menopausal transition, these same therapies are associated with increased health risks, such as the development of breast and ovarian cancers, which is mediated by the activation of the a (ERa), but not b (ERb), estrogen receptor isoform. Furthermore, ERb agonism has previously been shown to reduce preclinical indices of hot flashes, memory decline, anxiety, and depression. As most ERb agonists are …


Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward May 2021

Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward

Theses and Dissertations

The ability to effectively withhold an inappropriate response is a critical feature of cognitive control. Prior research indicates alterations in neural processes required for motor response inhibition in anxious individuals, including those with posttraumatic stress disorder (PTSD), and those who engage in regular cannabis use. However, thus far most research has examined how anxiety-related symptoms and cannabis use influence response inhibition in isolation of one another. The current study examined the interactions between anxious symptomology and recent cannabis use in a sample that recently experienced a traumatic event using functional magnetic resonance imaging (fMRI) during the completion of a Stop-Signal …


The Joint Influence Of Social Support And Coping On Anxiety In Aya Cancer Survivors, Genevieve Durso Apr 2021

The Joint Influence Of Social Support And Coping On Anxiety In Aya Cancer Survivors, Genevieve Durso

Theses and Dissertations

Background Adolescent and young adult (AYA) cancer survivors experience unique psychosocial needs during remission. Cancer-related anxiety is endemic amongst AYA survivors and can impede upon the survivor’s life post-cancer treatment. Independent of one another, confiding in a social support system and frequent engagement in coping mechanisms benefit those throughout the cancer experience, leading to more positive psychosocial outcomes. Hypothesis The dual utilization of one’s social support network and coping mechanisms would reduce cancer-related anxiety in AYA cancer survivors. Methods This study’s data was derived from a prior study conducted at Memorial Sloan Kettering Cancer Center, consisting of 128 adolescent and …


Cognitive-Behavioral Therapy For Anxiety In Youth With Autism: Paving The Way To Evidence-Based Practice, Michelle M. Kirkland Jan 2021

Cognitive-Behavioral Therapy For Anxiety In Youth With Autism: Paving The Way To Evidence-Based Practice, Michelle M. Kirkland

Theses and Dissertations

Anxiety is one of the most common and debilitating conditions co-occurring with autism spectrum disorder (ASD) as it occurs in up to 84% of individuals and can influence poor psychosocial adjustment, disruptions in individual, familial and school functioning, increased emotional and behavioral problems, self-injurious behavior(s), and an overall reduced quality of life (Meyer, Mundy, Van Hecke, & Durocher, 2006; Nadeau et al., 2011; Farrugia & Hudson, 2006; Kerns et al., 2015). To date, cognitive-behavioral therapy (CBT), an evidence-based treatment for anxiety in neurotypical youth, has seen modest, yet limited, promise in treating anxiety in youth with ASD. With extant research …


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 Jan 2021

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 …
