Validity Of The Delis-Kaplan Executive Function System In Pediatric Populations, Christopher J. Fisher

Doctor of Psychology (PsyD)

The Delis-Kaplan Executive Function System (D-KEFS) (Delis, Kaplan, & Kramer, 2001) is a battery of tests purported to measure those higher-level abilities generally termed "executive functions." While the D-KEFS possesses generally credible psychometric properties, the absence of adequately demonstrated "ecological validity" has been identified as a weakness of the D-KEFS. The purpose of this study was to attempt to assess the ecological validity of the D-KEFS using a sample of child chess players.

All 18 of the D-KEFS tests appropriate for children were administered in this study. For comparison purposes, several other measures were also administered: the Wisconsin Card Sorting …

Analysis Of Different Types Of Attentional Interference Compared To Working Memory, Joel A. Gregor

Doctor of Psychology (PsyD)

Previous studies have shown a relationship between working memory (WM) and the Color-Word Stroop Task (CWS). Newer Stroop-like tasks such as the Color-Block Stroop-like Task (CBS) have been shown to cause interference but the nature of the interference is unclear. This study attempted to compare CWS and CBS to tests of working memory, specifically the Digits Span Backward task (DB) and an Operation Span (OSPAN) task. The first experiment involved no auditory stimuli. No significant correlation was found between WM and CWS. This led to a second experiment with the digit span administered auditorily. Again, no significant correlation between CWS …

Childhood Developmental Trends In Executive Function As Measured By The Delis-Kaplan Executive Function System: An Exploration Of Gender Differences., Lane Karen Dewan

Doctor of Psychology (PsyD)

The purpose of this study is to examine the development of Executive Function (EF). Specifically, this study investigates whether there are consistent increases in EF performance on the Delis-Kaplan Executive Function System (D-KEFS) from the age of 8 years to 15 years. Gender differences in the development of EF are also examined. To this end, the standardization data for eight of the D-KEFS tests were analyzed, comparing performance across age groups (8- year-olds, 9-year-olds, etc.) and gender groups. Significant age effects were found for all tests overall. However, significant change between consecutive age groups was found only for some age …

Utilizing The Brief Symptom Inventory As A Prediction Tool For Treatment Response In Patients With Serious Mental Illness, Ryan Curtis Dix

Doctor of Psychology (PsyD)

Current data suggest that the cost of caring for people with serious mental illness in the United States was 2.64 billion dollars in the years between 1997 and 2004. The proper utilization of these funds is an important consideration if we are to successfully address the needs of this population. To maximize the use of mental health funds, the provider must quickly identify effective and efficient treatments. Assessment can facilitate the screening process and subsequent treatment decisions. For that reason, my research question addresses the issue of effective screening measures notably the Brief Symptom Inventory (BSI) in predicting movement through …

Exploring The Impact Of Rural And Urban Settings On Therapist Self-Disclosure, Katie Pierson Fruhauff

Doctor of Psychology (PsyD)

There has been a significant amount of research that addresses the topic of therapist self-disclosure. Issues such as what to disclose, when to disclose, the ethics of therapist disclosure, and the benefits and harm of therapist self-disclosure have been debated over the years. How self-disclosure varies among therapists has also been a focus of research. Unlike the area of self-disclosure, research on rural practice is a new and expanding field of research and there is great need for more research in this area. The hypothesis of this study proposes that therapist self-disclosure varies by setting; that rural therapists are more …

Differential Item Functioning In Asian-Americans On The Stanford-Binet Standardization Fifth Edition Verbal Subtests, Sheri L. Cardoza

Doctor of Psychology (PsyD)

This research examined the Standardization Edition of the Stanford-Binet, Fifth Edition (SB5), in order to assess the cultural validity of items using an index of differential item functioning (DIF) among Asian American and White/Caucasian American children. Archival data, obtained from the SB5 publisher, was used to determine DIF of items for the 101 Asian American and 200 White/Caucasian American children, ages 4-18. Potential bias was determined through the use of partial correlation. A significant correlation between item and an ethnicity code (with overall ability partialed out) indicated that, in general, one group performed better on a particular item than the …

Shame In Body Image In Children's Literature, Joy Mauldin

Doctor of Psychology (PsyD)

Even though children's books have been around for centuries, no research has addressed shame dynamics in children's literature. Psychologists can play an important role in the illumination of shaming content in literature, which will shape a child's perception of the world around her. In this qualitative study, five volunteers, non- psychologist adults ranging in ages 26-58 years, discovered that shame exists in children's books. The volunteers noted that shame can be both explicit and implicit in fashion. This study informs us that when given an understanding of shame, a non- psychologist layperson can identify shaming content in children's literature. This …

Phd And Psyd Graduates: More Alike Than Different, Elizabeth N. Wood

Doctor of Psychology (PsyD)

This study seeks to measure the attitudes and contributions of professional psychologists who have earned a PsyD degree. Initially developed as a degree to emphasize training in clinical practice over academia or research, the Doctor of Psychology degree follows the "Vail Model," also known as the "practitioner-scholar model." A random sample of practicing clinical psychologists was surveyed to determine if practicing c linical psychologists with a PsyD versus a PhD degree differ in attitude regarding serving diverse populations, public advocacy, and scholarship, and whether these attitudes are confirmed in practice. A questionnaire with practice-based questions was administered to 600 licensed …
