A Longitudinal Examination Of The Relations Between Racial Discrimination And Executive Function, Aldona Chorzepa

Theses and Dissertations

Discrimination has been linked to changes in executive function. This relationship may explain links between discrimination and adverse health and mental health outcomes, including depression, substance use, and health behavior. To date, the research examining this question has been limited, as the majority of studies reviewed employed experimental manipulations for discrimination exposure and tested acute same-day effects in the lab. Clarifying the extent to which exposure to discrimination impacts executive function over time in young adults is crucial to identifying opportunities for intervention. The current study evaluates the relations of both recent and lifetime exposure to racial discrimination to three …

Youth And Caregivers' Perceptions Of Racial Socialization: Examining The Interactive Role Of Risk And Cultural Resilience Factors As Predictors And Mental Health As Outcomes, Arlenis Santana

Theses and Dissertations

Black families' mental health, including that of the children and caretakers, is a persistent public health concern. Existing work documents that parental racial socialization messages are a protective process for the psychological well-being of Black children, youth, and emerging adults (Bannon et al., 2009). The majority of work to date has focused on youth, and we have limited information about the effects of racial socialization on caregivers’ mental health outcomes. It is also essential to examine the relation between racial socialization and outcomes among caregivers because, aside from their identity as parents, caregivers have other identities and experiences that deserve …

Effects Of Cumulative Trauma, Discrimination, And Racial Trauma Among African Americans, Brittany Renee Clayton

Theses and Dissertations

In the current study, we examined the impact of cumulative trauma, racial trauma, and everyday discrimination experiences within the African American community on psychological outcomes. One hundred and nineteen participants completed a series of self-report measures that analyzed their experiences of lifetime stressors, racial trauma, frequency of everyday discrimination, current posttraumatic stress disorder, depressive symptoms, and experiential avoidance levels. It was hypothesized that increased exposure to lifetime stressors, racial trauma events or experiences, and everyday discrimination would be associated with increased psychological distress. Correlations were conducted to identify and examine these relationships. This hypothesis was supported for lifetime stressor exposure …

Perceived Discrimination And Mental Health Outcomes In College Students: The Mediating Role Of Preventive Health Behaviors And Social Support, Sarah C M Morton

Theses and Dissertations

Perceived discrimination has been linked to adverse mental health outcomes, increased risk-taking behaviors, and poor engagement in health promoting behaviors. College students may be especially susceptible to negative mental health outcomes associated with discrimination due to the unique stressors faced by young adults (e.g., prolonged transition to adulthood, onset of mental health disorders, changes in social support). The current study examined the mediating and moderating roles of health behaviors and social support on the association between perceived discrimination and mental health outcomes (e.g., anxiety, depression, suicidality) in college students. A total of 709 college students (42.8% White; 72.2% female; 30.2% …

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

An Analysis Of Education As A Moderator Of The Relationship Of Discrimination To Depression, Jeavonna M. Coble

Theses and Dissertations

Racism has been observed as a highly prevalent psychosocial stressor across minorities, and consistently associated with depression across racial/ethnic groups. However, existing evidence is unclear on effective buffers of discrimination to depression. Researchers have hypothesized that education may mitigate discrimination’s effects on negative mental health outcomes. Evidence evaluating education as a buffer on the relations of discrimination to depression is limited. The analysis is further complicated as the evidence linking education level to discrimination exposure is also mixed. Although some studies indicate lower education levels are associated with greater perceived racism, many studies indicate an association of higher education with …

Perceived Discrimination And Food Consumption, Jessica Korins

Theses and Dissertations

Obesity is a public health concern that is associated with numerous life-limiting chronic illnesses such as diabetes and hypertension. Marginalized groups such as Black, Latinos, and Native Americans experience obesity and related illnesses at high rates. Research suggests that diet is one of the causes of these illnesses, and as such understanding the determinants of diet may assist in addressing health disparities in the United States. Literature suggests that diet may be associated with stressors such as perceived discrimination. However, few studies have assessed this relationship within the Native American population, and none have employed ecological momentary assessment (EMA) to …

The Role Of Perceived Heterosexism In Posttraumatic Stress Symptom Severity Among Trauma-Exposed Sexual Minority Individuals, Natalie M. Cereseto

Theses and Dissertations

This thesis employed structured posttraumatic stress disorder (PTSD) assessments, a micro-longitudinal 30-day daily diary assessment, and multilevel modeling to investigate the unique and interactive effects of traumatic stress and daily sexual minority-related discrimination on PTSD symptoms and negative affect in a diverse sample of 38 trauma-exposed SM individuals.

Social Constraints As A Mediator Of The Relations Of Discrimination To Anger Expression In A Community Sample, Sahira Hamid

Theses and Dissertations

Research has consistently demonstrated that anger is the dominant emotional response following experiences of racial discrimination. Studying anger itself may not be sufficient because anger can be expressed in a variety of ways, therefore it is necessary to examine different forms of anger expression. I hypothesized that social constraint would mediate the relations between discrimination and anger expression. Social constraint in the context of discrimination refers to an individual’s perception that communication about episodes of discrimination will be invalidated or minimized by others (either the same race or other race individuals). Social constraint, in turn, may influence the expression of …

Lesbian, Gay, And Bisexual Discrimination: An Examination Of The Role Of Blame Cognitions In Ptsd And Depression Symptoms, Timothy Stahl

Theses and Dissertations

Lesbian, gay and bisexual (LGB) emerging adults experience higher rates of trauma and discrimination, and subsequent PTSD and depression, than heterosexual emerging adults (Feinstein et al., 2012; Hatzenbuehler et al., 2008; Roberts et al., 2010). Our understanding of the relations between trauma/discrimination and psychiatric sequelae in LGB emerging adults is limited by: (1) uncertainty in the possible differential impact of LGB-specific trauma versus non-LGB-specific trauma, (2) uncertainty of the unique impacts of trauma and discrimination, and (3) lack of studies integrating cognitive theories of trauma (Brewin & Holmes, 2003) into Hatzenbuehler’s (2009) psychological mediation framework. This cross-sectional study included 82 …

Foreign Domestic Workers In Hong Kong: Identifying Risk Factors, Resilience, And Psychological Well-Being, Ka Yan Mok

Theses and Dissertations

Domestic workers, also known as house maids or handmaids, are a predominately female workforce that traditionally provides labor in upper-class households. With the increase of dual income families and the global expansion of the middle class, the demand for domestic workers increased, which facilitated the practice of importing lower-cost foreign domestic workers (FDWs) from developing areas. Hong Kong has the highest concentration of FDWs when compared to other metropolitan areas, such as Taiwan, Singapore, or New York. Since the trade began in the 1970s, qualitative research and journalistic investigations have reported that FDWs frequently encounter exploitation, including emotional, physical, and …

Is There Synergy Between Song Learning And Vocal Stimuli Discrimination Training?, Kenta Watanabe

Theses and Dissertations

Does auditory discrimination ability predict greater accuracy in imitating song? We investigated this question in zebra finch males by testing if the accuracy of vocal imitation of song syllables relates to auditory discrimination performance. The majority of birds improved on imitating their discriminated syllable pairs over non-discriminated syllable sets.

Discrimination, Mental Health, And Preparedness For Aging In Trans(Gender)/Gender-Nonconforming Adults, Richard S. Henry

Theses and Dissertations

This cross-sectional study examined relationships among discrimination, mental health (i.e., depression and anxiety), preparation for aging (i.e., familiarity and planning), social support, death attitudes, and aging anxiety among TGNC adults (N = 154). Neither discrimination nor mental health predicted preparation for aging familiarity or planning. Discrimination did, however, predict both anxiety and depression, although only the non-affirmation subscale was a unique predictor of both. As discrimination and mental health were not a significant predictor of preparedness for aging in the previous regressions, the hypothesized mediation model and subsequent moderated mediation models were not conducted. Additional exploratory multiple regressions were …

Cultural Correlates Of Ptsd In Latinos Residing In The U.S., Gabriela A. Nagy

Theses and Dissertations

The present study examined the associations between cultural variables (i.e., acculturative stress, discrimination, social support, migration planning, and reasons for migrating) and exposure to trauma and PTSD in a sample of Latinos (N=2,554) residing in the United States, who participated in the National Latino and Asian America Study (NLAAS). Results showed that there were significant positive associations between trauma exposure and migrating because of political reasons, migrating in search of medical attention, migrating due to

marital or family problems, and forced migration, suggesting they may be risk factors for being exposed to trauma. There was a negative association between trauma …

Religious Discrimination In Courtroom Oaths, Shannon M. Griffith

Theses and Dissertations

The current study investigated whether trust in Atheists moderates the relationship between prejudice against Atheists and belief in a hypothetical Atheists’ witness testimony. Pilot studies revealed that participants do not innately label witnesses who affirm as Atheists and determined that there was no significant difference between ratings of belief in Atheists witnesses in comparison to Christian witnesses. Responses from 185 MTurk participants confirmed that belief in witnesses did not significantly differ between Atheists and Christians. Furthermore, trust did not moderate the relationship between prejudice against Atheists and belief in the Atheist witness. These studies furthered research in distrust against Atheists …

An Integrated Behavioral Model Of Healthcare Utilization Among Transgender And Gender-Nonconforming Adults, Megan Elizabeth Sutter

Theses and Dissertations

Transgender and gender-nonconforming (TGNC) individuals in the United States experience significant marginalization due to stigma enacted at the structural, interpersonal, and individual levels. As a result, this population has reported increased behavioral and physical health needs, as well as unique barriers to healthcare. Moreover, TGNC individuals have reported greater experiences of childhood abuse compared to cisgender individuals. The cumulative experiences of stigma-related stressors and adverse childhood experiences put this population at risk for the development of mental and physical health problems, increasing need for health services. However, TGNC individuals have reported being denied medical care and postponing seeking care due …

The Mediating Role Of Mental Health In The Relationship Between Discrimination And Risky Behaviors In Lgbt Adults In Latin America, Annie Rabinovitch

Theses and Dissertations

The study explored relationships among discrimination experiences, mental health (i.e., anxiety symptoms, depression symptoms), risky behaviors (i.e., suicidal ideation, illicit substance use), religiosity, and social support in LGBT adults residing in Latin America. First, multiple regression analyses were conducted to identify patterns of connections among discrimination, mental health, suicidal ideation, and illicit substance use in sexual and gender minority adults from Latin American. Harassment/Rejection discrimination, but neither Work/School nor Other discrimination predicted suicidal ideation. None of the three discrimination subscales predicted illicit substance use. Work/School discrimination predicted mental health problems (Anxiety and Depression subscales of HSCL-25 combined), while Harassment/Rejection and …

Exploring Proximal And Distal Psychosocial Stressors Influencing The Health Outcomes Of Urban American Indians In The Midwest, Alina Aloma

Theses and Dissertations

Researchers have theorized that colonization and forced assimilation of American Indians/Alaska Natives (AI/AN) in the U.S. are associated with the current health outcomes of AI/AN groups. The literature has begun to link a number of negative health outcomes such as chronic illnesses, substance abuse, grief, depression, and anxiety with distal stressors associated with historical loss, as well as with proximal stressors that are continued reminders of historical trauma such as present day discrimination. The present study utilized a quantitative methodology along with a community informed framework through collaboration with multiple urban AI/AN-serving agencies in a metropolitan area of the Midwest …

An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus

Theses and Dissertations

A dog was trained to respond deferentially to two light-sound compounds. The dog was then tested with combinations of additional light and sound intensities. The dog appeared to use the information provided by both stimulus dimensions. This research is relevant to the understanding of information processing, specifically categorization and generalization.

Perceived Racism And Mental Health: A Meta-Analytic Review, Hokulea D. Conklin

Theses and Dissertations

The present study provides a synthesis of extant research examining the association between perceived racism and mental health. The aims of this study were to identify the overall magnitude of this association and to elaborate on the possible influence of participant characteristics (acculturation level, age, gender, race, education, and socioeconomic status) and study characteristics (year of data collection, geographic region of the study, and research design) in moderating this association. A total of 130 studies were included in the final analysis. The omnibus effect size for this meta-analysis was r = -.188 (p < .001), which indicates that higher instances of perceived racism were associated with lower levels of mental health. The overall magnitude of this association suggests a moderately small relationship between these two constructs. None of the participant characteristics moderated the results. However, studies conducted in more recent years appeared to be associated with effect sizes of greater negative magnitude than studies conducted in previous years. The implications of these findings for multicultural psychology are discussed and suggestions regarding future research in this area are presented.
