Lifestyle Choices Related To Food Consumption And Their Relationship To Depression, Steven L. Jennings Jr.
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
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
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 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 …
Generation Status, Ethnic Identity, Colonial Mentality, And Enculturation In Filipino Americans, Kamille Patricia Urmaza La Rosa
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 …
Testing Barriers To Non-Suicidal Self-Injury With College Students: Narcissistic Traits As Moderators, Philip Stoner
Testing Barriers To Non-Suicidal Self-Injury With College Students: Narcissistic Traits As Moderators, Philip Stoner
Dissertations
Research on non-suicidal self-injury (NSSI) has produced mixed findings, resulting in a lack of clarity regarding these behaviors (Klonsky & Meuhlenkamp, 2007). To address this, Hooley and Franklin (2018) developed the Benefits and Barriers Model (BBM) to provide a comprehensive understanding of NSSI, in which they identified the barriers that commonly prevent people from engaging in these behaviors (e.g., self-esteem, shame, and peer-bonding motivations/social norms). They also identified adverse childhood experiences (ACEs) as a distal predictor of NSSI, which aids people in overcoming the barriers to engaging in these behaviors. Recent NSSI literature has shown that college women in the …
Mental Construal And Alterations In Emotional Memory, Olivia D. Beers
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 …
Rural Pregnant Women’S Experiences With Substance Use Disorder: A Qualitative Study, Cami Weber
Rural Pregnant Women’S Experiences With Substance Use Disorder: A Qualitative Study, Cami Weber
Dissertations
Rural pregnant women with substance use disorder (SUD) are an understudied vulnerable population that often experiences poor pregnancy outcomes (Higgins et al., 2019; Jumah, 2016; Kramlich et al., 2018; Shaw et al., 2015). Despite the high prevalence and high burden associated with SUD, rural women are less likely than non-pregnant women to seek addiction treatment and complete an outpatient treatment program during pregnancy (Shaw et al., 2015). This study aimed to give voice to rural Missouri women with SUD. The research questions explored the life experiences and motivations for seeking treatment using a qualitative, descriptive research design with grounded theory …
