Examining Relations Among Positive And Negative Metrics Of Psychological Flexibility And Positive And Negative Outcomes Of Exposure To Trauma, Dustin A. Seidler

Dissertations

PTSD is a mental health condition that affects many people over the course of their life (National Comorbidity Survey, 2005), including veterans (Litz & Schlenger, 2009). However, many do not experience clinical levels of distress and some experience posttraumatic growth (PTG) resulting from such an event (Tedeschi, Park, & Calhoun, 1998). The Psychological Flexibility Model, of which Acceptance and Commitment Therapy (ACT; Hayes, Strosahl, & Wilson, 1999) is based, may help explain these phenomena. The purpose of this study was to examine these relationships utilizing a measure simultaneously assessing psychological flexibility and inflexibility. It was hypothesized that psychologically inflexible behaviors …

A Qualitative Understanding Of Gender-Responsive Youth Programming Within The Girls Rock Camp Alliance, Seyi Amosu

Dissertations

This study documented the gender-responsive youth programing strategies within Girls Rock camps using grounded theory methodology. Experiencing gender oppression is a stressor that creates an increased risk for mental and physical health concerns for gender-marginalized people. The risks for mental illnesses, because of gender-based oppression, is compounded when an individual holds additional marginalized statuses (e.g., age, race, ethnicity, social class, sexual orientation, ability status, etc.; APA, 2007). Gender bias has also been shown to negatively impact young people’s self-esteem, academic achievement, and vocational aspirations (Kamsler, 1992). Given this negative impact of gender bias, it is important to address gender related …

Getting Ahead Of The Game: A Preventative Assessment Plan For Intercollegiate Athletics, Kristiana Marie Feeser

Three validated measurement tools were used to measure burnout (Athlete Burnout Questionnaire; Raedeke & Smith, 2004), depression (Beck Depression Inventory-II; Beck et al., 1996), and transition readiness (British Athletes Lifestyle Assessment Needs in Career and Education; …

Fostering Resilience: A Pilot Study For Mindful Yoga As An Intervention For Adolescents Exposed To Chronic Adversity, Michele Pinellas

Dissertations

The effects of ongoing stress can cause chronic affect dysregulation, destructive behavior against self and others, learning disabilities, dissociative problems, somatization, and distortions in concepts about self and others (Bessel van der Kolk, 1994, p. 259). There may be particular benefits for youth who live in urban, underserved populations as they have experienced social challenges such as poverty, violence, drugs, racism, and immigration. Given the historical tendency of youth to express their emotions externally as a coping strategy, there is rationale to support a physically based treatment, like yoga, as an intervention for this population (Beltran et al., 2016). This …

Exploration Of The Link Between Migration And Acculturation Related-Stress, Attachment Style, And Psychological Distress In Arab Immigrants, Refugees, And Asylees, Hayat Nadar Psy.D.

Dissertations

Abstract

The migration process is fraught with experiences of ethnic discrimination and has been linked to heightened levels of psychological and acculturative stress. Interestingly, earlier research revealed a higher prevalence of insecure attachment in migrant compared to non-migrant populations. Attachment style may be influenced by sociocultural and sociopolitical forces and the associated prejudice and discrimination experienced by a particular migrant population. The current study was conducted to explore whether higher levels of sociocultural adversity were associated with increased psychological distress and attachment insecurity and to test attachment as a mediator between sociocultural adversity and psychological distress. Using a cross-sectional design, …

This paper has highlighted the effectiveness of the three models through testing each model three times via three endorsements featuring three different microcelebrities. The result of the survey suggests that self-disclosure practiced by the endorsing microcelebrity has a weak influence on peoples’ donation intention and attitude towards the endorsement. However, physical attractiveness of the endorsing microcelebrity has an influence on people’s donation …

Variable Compact Multi-Point Upscaling Schemes For Anisotropic Diffusion Problems In Three-Dimensions, James Quinlan

Dissertations

Simulation is a useful tool to mitigate risk and uncertainty in subsurface flow models that contain geometrically complex features and in which the permeability field is highly heterogeneous. However, due to the level of detail in the underlying geocellular description, an upscaling procedure is needed to generate a coarsened model that is computationally feasible to perform simulations. These procedures require additional attention when coefficients in the system exhibit full-tensor anisotropy due to heterogeneity or not aligned with the computational grid. In this thesis, we generalize a multi-point finite volume scheme in several ways and benchmark it against the industry-standard routines. …
