Taking A Cultural Perspective On Intimate Partner Violence, Claire Oxtoby

Dissertations (1934 -)

Intimate partner violence continues to be a growing social concern associated with extensive physical, emotional, and financial consequences. Previous models of intimate partner violence have failed to recognize the role cultural components may play in the etiology of violence, specifically cultural values, the bi-dimensional process of acculturation, and sociodemographic variables. Prior research has shown these factors all contribute to women‟s perceptions of violence and such perceptions may impact the relationship between exposure and emotional outcomes. The present study examined how women‟s cultural background influences their perceptions of violence and subsequent adjustment. Eighty-six Latina women completed measures assessing cultural values, acculturation …

Adhd Problem Recognition For Latino Parents: The Role Of Cultural Factors And Parental Cognitions, Brian W. Schneider

Dissertations (1934 -)

Latino youth experience similar or higher rates of mental health problems including ADHD, as compared to non-Latino children in the United States. They also are less likely to receive services due to a variety of access barriers and cultural factors which Latino families commonly experience. Behavioral help-seeking models have been developed to help explain the discrepancies between need and utilization for ethnically-diverse youth. Little research to date has investigated the impact of culture and parental beliefs of child behavior throughout the help-seeking process, including the beginning stage of problem recognition. Thus, the goal of the current study was to examine …

Traumatic Brain Injury And Executive Functioning In An Incarcerated Sample, Abigail A. Bernett

Dissertations (1934 -)

Incarcerated adults in the United States represent a significant segment of the population, and traumatic brain injury (TBI) in incarcerated populations has been identified as an area of public health concern. However, not much is known about it because research investigating TBI in incarcerated populations has focused primarily on its relationship to violent behavior. The existing research suggests that a history of TBI may be related to later violent behavior, criminal activity, mental health problems, and poorer institutional and community adjustment. Further, some of the cognitive deficits found in the general population following TBI, including executive dysfunction, have also been …

Traumatic Injury And Identity: Incorporating Traumatic Episodes Into The Life Story, Abbey K. Valvano

This project aimed to identify emergent themes within the life story narratives of spinal cord injured veterans and to both generate and test hypotheses regarding how emergent themes related to an indicator of post-trauma wellness. Seven themes were revealed within two specific sections of the life story interview. Findings revealed that individuals who author their life narratives in such a way as to demonstrate altruism and generativity showed significantly higher wellness. Further, narratives with …

Terror Management Theory: Interplay Between Mortality Salience, Death-Thoughts, And Overall Worldview Defense, Sharon R. Shatil

Dissertations (1934 -)

This study examines both the generalizability of Terror Management Theory (TMT) and the mechanisms by which individual difference variables work in the TMT model. A plethora of research exists to support TMT, a theory that explains much of human behavior as attempts to buffer the potential for anxiety provoked by being aware of one's own inevitable mortality (Pyszczynski et al., 2003). This dissertation investigated the generalizability of Terror Management Theory (TMT) and the mechanisms by which individual difference variables work in the TMT process. In order to do so, an operationalization of the variable "overall worldview" was provided. Participants consisted …
