Psychometric Properties Of Diagnostic Assessment Instrumentsfor Autism Spectrum Disorders In A Community Sample Aged 2 Through 17 Years, Sheryl Lozowski-Sullivan

Dissertations

Recent estimates of the incidence and prevalence of autism spectrum disorders (ASDs) indicate substantial increases over the past 20 years (Centers for Disease Control and Prevention, 2009; Fombonne, 2009; Matson & Kozlowski, 2011; Schreibman & Koegel, 2005; Wing & Porter, 2002), in part because of the availability of significantly improved diagnostic assessment instruments (Lord & Corsello, 2005; Schreibman, 2005). In highly structured research settings, some of these diagnostic instruments correlate well with each other; however, few studies have examined the relation between these diagnostic tools in traditional clinical practice (Mazefsky & Oswald, 2006; South et al, 2002). This study examined …

The Effects Of Yellow Rectangular Rapid-Flashing Beacons (Rrfbs) Onmotorists' Yielding, Exit Lane Encroachment And Conflicts At Fire Station Exits, Erick K. Marmolejo

Dissertations

The purpose of the current study was to explore the extent to which yellow rectangular rapid-flashing beacons (RRFBs) affected motorists' yielding, exit-lane encroachment and conflicts at fire station exits. This study explored the use of RRFBs attached to sign prompts that alerted motorists to the presence of exiting emergency vehicles. These signs were activated only during an exit event. It was hypothesized that motorists would increase their frequency of safe and legal yielding in the presence of the RRFB intervention when compared to the absence of contextually activated RRFB units. This study was conducted in a midwestern town in front …

Examination Of Anxiety And Substance Use Symptoms In Trauma Exposed Versus Environmentally Stressed College Students, Theresa M. Souza

Dissertations

Anxiety is a common problem among the college population, which rarely occurs in isolation. Oftentimes, an individual abuses substances in an attempt to eliminate the short term affect of these conditions. Post Traumatic Stress Disorder (PTSD), is the most persistent and severe type of anxiety disorder. It has been a long-standing belief within the psychological community that in order for PTSD to develop, the individual must first experience a traumatic event which meets certain criteria and must evidence a definable emotional response during the event. A recent study found PTSD in individuals who had not experienced the type of trauma …

The Experiences Of Married International Graduate Students And Their Accompanying Non-Student Spouses In The Us Culture: A Qualitative Study, Adriana Yellig

Dissertations

Many studies document the experiences of single international students in the U.S. culture. However, little is known about the experiences of married international students, their marital relationships, and the experiences of their accompanying nonstudent spouses in the U.S. culture.

This qualitative phenomenological study focused on the experiences of married international graduate students and their accompanying spouses in the U.S. culture. Additionally, the study explored the impact of cultural influences on the participants' marital relationships, as well as the impact of marriage on their adjustment to the culture.

The study included twenty participants (ten couples) from a range of countries, most …

Comparing First Generation And Non-First Generation African-American Students At Predominately White Institutions, Leatrice Renee Brooks

Dissertations

The comparative experiences of first generation and non-first generation Black students at predominately White institutions were examined to gain information about the predictors and relationships between adjustment (including academic and personal-emotional) coping (4 styles), race-related stress, and racial identity development (6 levels). Results from a simultaneous multiple regression revealed a significant positive adjustment profile that included being non-first generation, low disengagement coping, problem-oriented coping, and low pre-encounter self-hatred racial identity development. The standardized coefficients for the first canonical analyses indicated significant relationships between pre-encounter self-hatred and low personal-emotional adjustment; and for the second, low disengagement coping and personal-emotional adjustment. For …

The Effects Of Implementing Restorative Justice In An In-School Suspension Program, Nikki Brown-Kersey

Dissertations

The purpose of the proposed study was to assess the effects of implementing an in-school suspension program with a Restorative Justice component on office referrals, suspensions and grade point averages. The combination of Restorative Justice and inschool suspension as an alternative to out-of-school suspension warrants empirical evaluation. According to recent research, neither Restorative Justice nor in-school suspension alone have enough empirical evidence to support their success and continued use in schools in isolation. The positive aspects of each combined may produce a more successful alternative to suspension. A group design procedure was used to assess if significant changes in the …
