Combat Posttraumatic Stress Disorder: Effect of Intelligence on Symptomatology

Combat Posttraumatic Stress Disorder: Effect of Intelligence on Symptomatology

Date: May 2004
Creator: Crisp, William A.
Description: The objective of this study was to examine the relations between Posttraumatic Stress Disorder symptomatology and intelligence. Thirty American combat veterans of the Vietnam War, diagnosed with chronic PTSD, were given a psychodiagnostic structured interview. Participants were assessed for Intelligence Quotient as well as the veracity of their self report. The study found that there were significant differences in how participants experienced their PTSD symptoms that were correlated with intelligence. The higher IQ participants reported more frequent and intense guilt related symptoms as well as more intense intrusive recollections. The lower IQ participants experienced more frequent startle responses, more intense problems related to falling or remaining asleep and more frequent affective symptoms related to emotional numbing. Psychologists could use these differences in how PTSD is experienced in treatment planning. It may be useful for therapy to address sleep disturbances and affective numbing in lower IQ individuals. Therapy for higher IQ individuals may be more useful if it addresses feelings of guilt and intrusive recollections.

The structure of insight in patients with psychosis.

The structure of insight in patients with psychosis.

Date: December 2004
Creator: Gonterman, Andrea R.
Description: Failure to acknowledge their mental illness occurs in approximately half of all psychotic patients. Interest has been recently been refocused on insight (i.e., awareness of mental illness), and its associations with treatment compliance and better prognosis. Researchers have called into question the traditional factor structure of insight, instead viewing and defining it as a multidimensional and continuous construct. While factor analytic research has suggested that insight is an independent feature of psychotic disorders rather than a secondary manifestation of psychotic symptoms, several factor analytic studies have identified only one higher-order factor. Furthermore, a significant amount of the research literature has assessed insight or analyzed its relationships using only a single insight score. The current study evaluated the structural model of insight and assessed the associations between the different proposed dimensions of insight and psychotic symptoms. One hundred and six participants recruited from both inpatient and outpatient settings with a diagnosis of schizophrenia, schizoaffective disorder, psychotic disorder NOS, or bipolar disorder with psychotic features were rated on David's Schedule for Assessing Insight-Expanded Version (SAI-E), Birchwood's Insight Scale (IS), and the Brief Psychiatric Rating Scale (BPRS) or the Positive and Negative Syndrome Scale (PANSS). Structural equation modeling (SEM) was utilized to provide ...

Isolation of a  Pseudomonas aeruginosa Aspartate Transcarbamoylase Mutant and the Investigation of Its Growth Characteristics, Pyrimidine Biosynthetic Enzyme Activities, and Virulence Factor Production

Isolation of a Pseudomonas aeruginosa Aspartate Transcarbamoylase Mutant and the Investigation of Its Growth Characteristics, Pyrimidine Biosynthetic Enzyme Activities, and Virulence Factor Production

Date: December 2004
Creator: Hammerstein, Heidi Carol
Description: The pyrimidine biosynthetic pathway is an essential pathway for most organisms. Previous research on the pyrimidine pathway in Pseudomonas aeruginosa (PAO1) has shown that a block in the third step of the pathway resulted in both a requirement for exogenous pyrimidines and decreased ability to produce virulence factors. In this work an organism with a mutation in the second step of the pathway, aspartate transcarbamoylase (ATCase), was created. Assays for pyrimidine intermediates, and virulence factors were performed. Results showed that the production of pigments, haemolysin, and rhamnolipids were significantly decreased from PAO1. Elastase and casein protease production were also moderately decreased. In the Caenorhabditis elegans infection model the nematodes fed the ATCase mutant had increased mortality, as compared to nematodes fed wild type bacteria. These findings lend support to the hypothesis that changes in the pyrimidine biosynthetic pathway contribute to the organism's ability to effect pathogenicity.

Creator: Dinc, Nefin
Description: Recent political developments in the world show us that different cultures need to know and understand each other better. Even though technological developments like the Internet, satellites, cable television and conglomeration of big media entities have made mass communication more effective and faster, we cannot easily say that these developments help to bring world cultures together. As a result, mass audiences are not very much able to see what few productions do speak to these issues in a constructive manner. The main aim of this documentary film project is to serve as a small step towards helping different cultures to understand each other better. This documentary film conveys the basics of Mevlevism by following the formal gatherings of a Mevlevi den in Istanbul, Turkey. A den or tekke is a place where Islamic people gather and perform their religious activities. During these gatherings they do the sema, they pray, they listen to music, and they discuss spiritual matters. Sema is the entire ritual they perform as part of their ceremonies including listening to music, singing and chanting to attain a state of religious emotion and ecstasy or vecd. The documentary film is structured around a twelve year old girl, Elif, ...

From inside the Arab family: What literacy practices occur when raising bilingual and biliterate children?

From inside the Arab family: What literacy practices occur when raising bilingual and biliterate children?

Date: December 2004
Creator: Alshaboul, Yousef Mohammad
Description: Living in the United States creates unique challenges in biliteracy and bilingualism for the Arab family. While extant literature provides insight into the literacy interactions and experiences of families from many other cultures now living in the U.S. , there is next to nothing regarding the Arab family literacy experience. Thus, knowledge about the literacy activities Arab families engage in as they gain access to and knowledge of a new culture and language is important. The purpose of this study was to investigate and describe the literacy practices of the Arab families raising bilingual and biliterate children in the U.S. This study , using methodology based on ethnographic approaches, investigated the literacy events, behaviors and interactions which occurred within one Arab family over a 16-week period. A second group of participants were 5 other Arab families living in the U.S. Data sources included video and audio recordings, field notes, observations, journals, informal interviews, and artifacts of children's literacy. The researcher and the participants engaged as co-participants in the research. Findings showed that driving factors behind home literacy practices were religious beliefs and the imminence of return to the home country. Arab mothers were found to yield a heavy influence on ...

Age and Responses to the Events of September 11, 2001

Age and Responses to the Events of September 11, 2001

Date: December 2004
Creator: Holmes, D. Nicole
Description: Following the terrorist attacks on the United States on September 11, 2001, many turned to the field of psychology for greater understanding of the impact of such events and guidance in supporting our citizens. This study sought to gain greater understanding of the differential impact of the September 11th attack on individuals by investigating the influence of age, psychological hardiness, and repression versus sensitization as forms of coping behavior on psychological health. Both an initial cross-sectional sample (172 young adults & 231older adults) and a short-term longitudinal follow-up (39 young adults & 58 older adults) were included in the study. Older age, psychological hardiness and the use of a repressing coping style were found to each individually relate to greater resilience/less dysfunction at both time one and two. For young adults, high hardy repressors faired best, followed by high hardy sensitizers. Low hardy young adults demonstrated similar levels of dysfunction regardless of coping style (repressions/sensitization). For older adults, coping style impacted both high and low hardy individuals equally, with high hardy repressors demonstrating greater functioning. This study attempted to gain greater insight into explanations for these and previous findings of greater resilience among older adults. In explaining the greater resilience ...

A two-year college typology for the 21st century: Updating and utilizing the Katsinas-Lacey classification system.

A two-year college typology for the 21st century: Updating and utilizing the Katsinas-Lacey classification system.

Date: May 2005
Creator: Hardy, David Earl
Description: This study had two primary purposes. The first goal was to bring the 1993/1996 Katsinas-Lacey two-year college classification system into the 21st century using data from the 2000 United States Census and the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS) surveys for the 2000-2001 and 2001-2002 academic years. The second goal was to create a descriptive portrait of the universe of two-year, publicly controlled institutions that primarily offer the associate's degree mapped against the updated classification system and to describe and discern similarities and differences within this particular population by class and subclass in terms of multiple measurable characteristics for which IPEDS data were available. The study, based upon classification theory utilized in social science and management sciences - particularly the work of Bailey and McKelvey - assessed the efficacy of a number of other recent proposed community college classification systems, the original Katsinas-Lacey system and the revised version of Katsinas-Lacey created through the current research. It found both the original Katsinas-Lacey system and the revised version to meet the criteria for a well-made classification model. The study includes directories of all colleges and universities in the United States that offer the associate's degree with geographic, ...

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Date: May 2004
Creator: Lee, Coral Em
Description: Previous research has shown that variability is a reinforceable dimension of operant behavior. Additionally, it has been demonstrated that learning is facilitated when variability in responding is high. In this research, variability was observed within an operant composed of any sequence of six left and right key presses. Variability was either a requirement for point delivery (VAR conditions) or points were delivered independent of variability (ANY conditions). Two groups of college undergraduates experienced different orders of conditions. One group began the experiment under VAR conditions, and the variability requirement was later removed. The other group began the experiment under ANY conditions, and the variability requirement was later added. A concurrently reinforced target sequence (i.e., an always-reinforced sequence of left and right key presses) was introduced to both groups after these orders of conditions had been experienced. A variety of outcomes resulted. Subjects learned the target sequence when variability was both high and low with non-target points concurrently available. Other subjects learned the target sequence after all non-target point deliveries had been suspended. One subject failed to acquire the target sequence at all. These results were compared to previous findings and possible explanations for the discrepancies were suggested.

The WASI™ as a Screening Tool for Counselors in the Referral Decision for a Neuropsychological Evaluation

The WASI™ as a Screening Tool for Counselors in the Referral Decision for a Neuropsychological Evaluation

Date: August 2004
Creator: Snowden, Marie Dillon
Description: When a client has cognitive impairment resulting from cerebral dysfunction (CD) that goes undiagnosed and, therefore, untreated, psychotherapy and rehabilitation outcome is likely to be impacted negatively. Due primarily to managed care, screening for CD has reduced substantially. Master's level counselors need a cost-efficient way to detect possible CD and, thus, justify referral for neuropsychological evaluation. This study examined the Wechsler Abbreviated Scale of Intelligence™ (WASI™) instrument's ability to screen for possible CD by examining the relationship between a) WASI Performance IQ (PIQ) and Verbal IQ (VIQ) scores and neuropsychological test scores, and b) the VIQ-PIQ discrepancy and the severity of disability. In this retrospective study, test scores were extrapolated from neuropsychological assessments conducted between 2001 and 2004 on 73 CD-diagnosed adults at a CARF accredited rehabilitation facility. Disability severity ratings of mild, moderate, and severe were assigned based on clinical judgment and interrater agreement. The assessment battery included the WASI and several neuropsychological tests: Halstead-Reitan TPT, TMT-A and B, and FOT; WMS-III VR-I and 2, LM-1 and 2, and MC; McCarron-Dial HVDT; SDMT; and SCT. Based upon a multitrait-multimethod matrix, mild to moderate convergent and discriminant validity was found with the WASI VIQ and PIQ traits among neuropsychological verbal ...

An Assessment of the Effectiveness of the CHAMPS/Life Skills Program at the University of North Texas: A Pilot Study

An Assessment of the Effectiveness of the CHAMPS/Life Skills Program at the University of North Texas: A Pilot Study

Date: May 2004
Creator: Goddard, Michael
Description: This study seeks to determine the effectiveness of the Challenging Athletes Minds for Personal Success (CHAMPS)/Life Skills program at the University of North Texas, as perceived by the student athletes who participate or participated in this program. The study attempts to measure the extent to which the student athletes feel that the program had value; if they received helpful information to support them through their college career to career transition; if the student athletes felt that the program provided them with skills to encourage better self-esteem; and if they believed that the CHAMPS/Life Skills program provided them with leadership and character education. The study, conducted in the Fall of 2003, had 163 respondents. An instrument was developed to determine student athletes' perceptions of the effectiveness of the CHAMPS/Life Skills program at UNT. The instrument consisted of 30 questions using a Likert-type scale. A Mann-Whitney U, a non-parametric t-Test, was utilized to analyze the data. This type of t-Test was used because it is specifically designed to compare the means of the same variable with two different groups and account for non-homogeneous groups. The lack of homogeneity was very likely influenced by the unequal group sizes. Generally, all aspects of the ...
