An analysis of selected pre- and post-admission variables as they relate to the retention of new freshmen at a large, research, public university

Boyd, Kriss Hope 30 September 2004 (has links)
Texas A&M University changed the criteria for freshman admission after a legal decision in 1996 removed ethnicity from the list of possible admission criteria. The process now includes subjective criteria such as activities, leadership, service and awards as well as the traditional objective criteria such as test scores and rank in high school class. The purpose of this study was to analyze the relationship between some of the admission criteria and retention of freshmen from the first fall to the second fall. Retention of freshmen is a performance indicator for higher education in Texas. The results of the logistic regressions showed that the relationships were modest at best and had a very small pseudo r2. The objective criteria of test scores and high school rank were either not significant or did almost nothing to increase the odds ratio. The only variable that was significant in the regression, but had a modest odds ratio, across the regression for all students and for the regressions for the subgroups of female and male students, Anglo, Hispanic and Asian American students, and for students from targeted, disadvantaged high schools was parents' education level. The points assigned to students by admissions counselors for self-reported leadership activities were significant for the regressions for all students, for female students and for Anglo students, but did very little to increase the likelihood of retention. Test scores were significant in the regressions for all students, for female students and for Hispanic students, but did almost nothing to increase the likelihood of retention. None of the variables were significant in the regression for the small group of African American students. One conclusion from the analysis is that some students whose parents have the lowest levels of education and some students from targeted high schools have unmet needs that cause higher attrition rates for these groups. However, even within these groups, there are other factors driving the students' commitment to stay enrolled for the second year at the institution than those included in this study.

Predictors of Success: Medical Laboratory Associate in Science Degree Program

Madan, Nilia M 13 July 2012 (has links)
Hospitals and healthcare facilities in the United States are facing serious shortages of medical laboratory personnel, which, if not addressed, stand to negatively impact patient care. The problem is compounded by a reduction in the numbers of academic programs and resulting decrease in the number of graduates to keep up with the increase in industry demands. Given these challenges, the purpose of this study was to identify predictors of success for students in a selected 2-year Medical Laboratory Technology Associate in Science Degree Program. This study examined five academic factors (College Placement Test Math and Reading scores, Cumulative GPA, Science GPA, and Professional [first semester laboratory courses] GPA) and, demographic data to see if any of these factors could predict program completion. The researcher examined academic records for a 10-year period (N =158). Using a retrospective model, the correlational analysis between the variables and completion revealed a significant relationship (p < .05) for CGPA, SGPA, CPT Math, and PGPA indicating that students with higher CGPA, SGPA, CPT Math, and PGPA were more likely to complete their degree in 2 years. Binary logistic regression analysis with the same academic variables revealed PGPA was the best predictor of program completion (p < .001). Additionally, the findings in this study are consistent with the academic part of the Bean and Metzner Conceptual Model of Nontraditional Student Attrition which points to academic outcome variables such as GPA as affecting attrition. Thus, the findings in this study are important to students and educators in the field of Medical Laboratory Technology since PGPA is a predictor that can be used to provide early in-program intervention to the at-risk student, thus increasing the chances of successful timely completion.

Homeless Predictors in the Older Adult Population

Lewallen, Jina P. 05 1900 (has links)
This secondary research study uses data from two convenience samples of homeless persons in Central Arkansas collected during 2004 and 2011 Point in Time Counts. The prevalence of predictors of homelessness are compared across years, and also compared by age (<50 and > 50) controlling for year of survey. The number of older adults increased significantly between 2004 and 2011 surveys, and reporting serious mental illness and veteran status significantly decreased from 2004 to 2011. Age differences were noted in 2004 with older adults more likely to report serious mental illness in comparison to younger adults. Older adults were also more likely to report veteran status in comparison to younger adults during both the 2004 and 2011 surveys. The predictors of homelessness -- including serious health problems, substance abuse, race, age, and developmental disabilities-- remained fairly consistent from 2004 to 2011 and across "age groups". In addition to Point in Time data, qualitative surveys and interviews of providers were performed for their observations of the older homeless population. Providers indicated their belief that the older homeless population is increasing. Providers suggested possible challenges and reasons for the increase among older adults who are homeless. In central Arkansas, service providers feel the current economy, programs, and agencies that provide homeless services and funding sources are adequate at this time as evidenced by no increase in numbers. Due to new funding, improvement has occurred with the veteran population through VA programs. Even though this research did not find any change in gender, the providers feel that for future homeless, trends in gender (women in poverty), as well as older adults becoming homeless for the first time, should be watched in addition to other predictive factors such as the economy, increase in substance abuse, and physical and mental health concerns.

Predictors of Treatment Completion for Adolescent Males in a Mental Health Residential Program

Long, Elise Wade 04 October 2000 (has links)
PREDICTORS OF TREATMENT COMPLETION FOR ADOLESCENT MALES IN A MENTAL HEALTH RESIDENTIAL PROGRAM Elise Wade Long Eric E. McCollum, Ph.D., Chair Human Development (Abstract) Although there is significant prevalence of serious emotional disturbance in adolescents, research concerning the determination of appropriate levels of care is lacking. This study examined predictors of successful treatment completion in male adolescents (n=132) who were admitted to a suburban residential treatment center during a ten year period. Data on pre-treatment client variables, family participation in treatment, and length of stay were collected on each subject. Data were collected by sequentially reviewing 132 file records of previously discharged clients. Five variables (age upon admission, family constellation, family participation, previous out-of-home placements, criminal involvement) did not predict successful treatment completion. A significant relationship was found between length of stay in residential treatment and successful treatment completion. Implications for decision-making regarding admissions to residential treatment programs and needs for future research are discussed. / Master of Science

Predictors of Persistence and Resurgence: Evaluation of a Behavioral Momentum-Based Approach

Sweeney, Mary M. 01 May 2014 (has links)
The basic behavioral process of operant conditioning contributes to problem behaviors in psychological disorders. Escape from aversive situations in depression, the rewarding effects of drugs in substance abuse, and the receipt of caregiver attention for disruptive behavior in intellectual or developmental disabilities are just a few examples of operant reinforcement contingencies that perpetuate undesirable behavior. Behavioral treatment strategies often introduce alternative sources of reinforcement for a desirable alternative behavior. Although treatments can be effective, alternative reinforcement removal can trigger relapse of the problem behavior, called resurgence. Persistence in alternative reinforcement treatments and resurgence can be understood from the prospective of behavioral momentum theory, which predicts greater operant persistence and resurgence when there is a greater history of reinforcement associated with the context in which an operant response occurs. Shahan and Sweeney incorporated resurgence into the framework of behavioral momentum theory, and the proposed model makes explicit qualitative and quantitative predictions that are tested in this dissertation. Chapter 1 provides the background and significance of resurgence of operant behavior, and gives an introduction to behavioral momentum theory and the quantitative model of resurgence. Chapter 2 reports two recently published experiments that show increased time with alternative reinforcement treatment reduces subsequent resurgence in an animal model with pigeon subjects. The study presented in Chapter 3 examined how persistence and resurgence may be affected when alternative reinforcement is delivered in a novel context. This experiment, which used rat subjects, integrated and compared the animal model of resurgence with another operant relapse phenomenon, renewal, in which context change alone is known to induce relapse of a previously reduced response. Chapter 4 describes a study with college undergraduates as participants that tested the feasibility of a brief, three-alternative, forced-choice procedure as a human operant model of resurgence. Despite procedural manipulations of the length of training and probability of reward for choice of the target stimulus, resurgence was never consistently observed. Chapter 5 provides an integrative discussion of these research topics.

Medication use patterns of antiepileptics and epileptic events

Shcherbakova, Natalia G., 1982- 23 October 2012 (has links)
The purpose of this study was to identify clinical and demographic predictors of seizure recurrence in medically-treated patients with epilepsy. Innovus Invision™ Data Mart insurance claims from January 1, 2007 to September 30, 2010 were retrospectively analyzed. Patients aged 18-64 years with a primary or secondary diagnosis of epilepsy and >1 prescription claim for an antiepileptic drug (AED) pre-index were included. The primary outcome was incidence of seizures defined as an occurrence of an emergency room visit, ambulance service use or hospitalization with a primary or secondary diagnosis of epilepsy during the 1-year follow-up period. Predictor variables included antiepileptic drug (AED) adherence (Proportion of Days Covered ≥ 80 %), general comorbidity (Charlson’s Comorbidity Index ≥ 1), any mental health comorbidity, evidence of a prior seizure, type of epilepsy diagnosis (intractable versus non-intractable), presence of AED-interacting medications and any bioequivalent AED switch. The covariates included age, gender and geographic region of residence. The overall incidence of post-index seizures in the 1-year follow-up period for all four monotherapy cohorts combined was 5.3 % (n=166/3140), but was higher for the Keppra®/levetiracetam cohort (7.9%; n=88/1114) compared to the other cohorts [Lamictal®/lamotrigine (3.9%; n=45/1143), Trileptal®/oxcarbazepine (4.0%; n=18/456) and Topamax®/topiramate (3.5%; n=15/427)]. The combined cohort analysis demonstrated that pre-index seizures (odds ratio [OR] = 4.28; 95% CI, 2.81-6.53), any mental health comorbidity ([OR] = 3.41; 95% CI, 2.10-5.54), Charlson comorbidity Index ≥1 ([OR] = 2.88; 95% CI, 1.96-4.24) and monotherapy with Keppra®/levetiracetam ([OR] = 1.54; 95% CI, 1.03-2.31) were significant predictors of seizure recurrence. Among covariates, only geographic region was a significant predictor, with patients residing in the Northeast U.S. having higher odds of post-index seizure ([OR] = 1.92; 95% CI, 1.19-3.10), while controlling for clinical, medication and demographic characteristics. A bioequivalent AED switch, type of epilepsy diagnosis, AED adherence and the presence of interacting medications were not significant predictors of seizure recurrence in the combined cohort (p>0.05). Results indicate that epilepsy patients with comorbid conditions (both mental and somatic diseases), as well as patients who may have initially been unstable (with previous seizure occurrences) were more likely to experience seizures during the follow-up period. / text

Predictors of Peritonitis Among Canadian Peritoneal Dialysis Patients

Nessim, Sharon J. 15 February 2010 (has links)
Despite the decreasing incidence of peritoneal dialysis (PD) peritonitis over time, its occurrence is still associated with adverse outcomes. This thesis focuses on determining factors associated with PD peritonitis in order to facilitate identification of patients at risk. Using data collected in a multicentre Canadian database between 1996 and 2005, the study population comprised 4,247 incident PD patients, of whom 1,605 had at least one peritonitis episode. Variables independently associated with peritonitis included age [rate ratio (RR) 1.04 per decade increase, 95% CI 1.01-1.08], Black race (RR 1.37, 95% CI 1.00-1.88) and having transferred from hemodialysis (RR 1.24, 95% CI 1.11-1.38). There was an interaction between gender and diabetes (p=0.011), with an increased peritonitis risk only among female diabetics (RR 1.27, 95% CI 1.10-1.47). Choice of continuous ambulatory PD vs. automated PD did not influence peritonitis risk. These results contribute to our understanding of peritonitis risk among PD patients.

Juvenile Drug Court: Predictors of Graduation and Non-Graduation Status

Hoyt, Joshua D. 13 June 2012 (has links)
Drug use has become an epidemic in our nation, filling our jails and prisons with nonviolent offenders. Studies have shown that adult drug courts are a good alternative to the prison system by being successful in reducing recidivism and long term costs. To date, however, few studies have looked specifically at the effectiveness of juvenile drug courts and their cost effectiveness. Further, the possible benefits of lower attrition rate and cost benefit are being overshadowed by the low attrition rate among juvenile drug court participants. Nearly half of all juvenile drug court participants do not complete the juvenile drug court program. Additionally, studies have shown that juvenile participants who do graduate have lower attrition rates and other benefits. Due to the benefits of juveniles who graduate from a juvenile drug court program, understanding the difference between those who graduate and those who do not can add significant understanding on how juvenile drug courts can be modified in order to help juveniles successfully graduate from the drug court program. This study will shed light on specific pre-drug court demographics and behaviors that were different among juveniles who successfully graduate and those who are unsuccessful in graduating from the juvenile drug court program. The Idaho Supreme Court, which oversees the JDC program in Idaho, collaborated in this effort by providing a statewide juvenile drug court data set, drawn from the Idaho Statewide Trial Court Automated System (ISTARS). The data set included all information that was gathered for drug court participants during the January 2004 - December 2005 period, for who had completed the program either successfully or unsuccessfully. Subsequent analysis of the data clarified the difference between groups of those who graduated and those who did not graduate, specifically that a significant difference was found between groups in the following characteristics: gender, school attendance, and in-treatment drug tests.
