Correction Of Verication Bias Using Log-Linear Models For A Single Binaryscale Diagnostic Tests, Haresh Rochani, Hani M. Samawi, Robert L. Vogel, Jingjing Yin

Biostatistics Faculty Publications

In diagnostic medicine, the test that determines the true disease status without an error is referred to as the gold standard. Even when a gold standard exists, it is extremely difficult to verify each patient due to the issues of costeffectiveness and invasive nature of the procedures. In practice some of the patients with test results are not selected for verification of the disease status which results in verification bias for diagnostic tests. The ability of the diagnostic test to correctly identify the patients with and without the disease can be evaluated by measures such as sensitivity, specificity and predictive …

Monitoring For Adverse Events Post Marketing Approval Of Drugs, Karl E. Peace, Macaulay Okwuokenye

Biostatistics Faculty Publications

This brief communication provides information to those developing monitoring plans for serious adverse events (SAE’s) following regulatory approval of a new drug. In addition, we (1) illustrate how many patients would need to be treated in order to have high confidence of seeing at least 1 pre-specified SAE, (2) show that absence of proof of a SAE is not proof of absence of that SAE, and (3) identify statistical methodology that could be used for formal statistical monitoring of SAE’s.

Social And Behavioral Implications Of National Collegiate Athletic Association Sickle Cell Trait Screening: The Athletes' Perspective, Raymona H. Lawrence, Alison Scott, Carlton Haywood Jr., Kayin Robinson, Mondi Mason

Community Health Faculty Publications

Background: In August 2010, the National Collegiate Athletic Association (NCAA) implemented a policy mandating sickle cell trait (SCT) testing for all Division I collegiate athletes. Subsequently, all Division II-III athletes were also compelled to undergo SCT testing. This decision has met with controversy among healthcare providers, researchers, and sickle cell advocates. However, there is little information concerning the athletes’ perspective of this policy. The purpose of this paper is to report the findings of a qualitative study that explored college athletes’ perceptions of sickle cell trait SCT, NCAA policies on SCT testing, and potential implications of SCT screening.

Think Inside The Blocks: Health Literacy Outreach To Disadvantaged People In Their Own Environment, Nancy Patterson

Georgia International Conference on Information Literacy

This bilingual (Spanish/English) poster highlights six creative health literacy outreach projects that have proven to be successful in increasing participation in health-related events in their communities and in boosting health literacy in the process.

For example, in Georgetown, South Carolina, a beauty salon owner, concerned about her clients’ frequent frustration with trying to decipher medical information, partners with her local public library and is grant funded to provide a Wellness Workstation in her salon. Years later, her clients research health information between services using the workstation, evening health literacy classes are regularly conducted for community members and continued funding has …

Exploring Cyber Harassment Among Women Who Use Social Media, Sloane Burke Winkelman, Jody Oomen-Early, Ashley D. Walker, Lawrence Chu, Alice Yick-Flanagan

Community Health Faculty Publications

The number of Internet users around the word is at an all-time high. The majority of North Americans are internet users and over two-thirds participate in some kind of social network (i.e. Facebook, Twitter, etc.). Social networks and mobile technology enable individuals to connect instantaneously or asynchronously, across geographic boundaries publicly or anonymously. Few studies exploring cyber harassment have been conducted, primarily because these technologies are relatively recent. The purpose of this descriptive study was to examine U.S. women's experiences with and attitudes toward cyber harassment by way of an anonymous electronic survey. A total of 293 adult women (mean …

Size And Power Of Tests Of Hypotheses On Survival Parameters From The Lindley Distribution With Covariates, Macaulay Okwuokenye, Karl E. Peace

Biostatistics Faculty Publications

The Lindley model is considered as an alternative model facilitating analyses of time-to-event data with covariates. Covariate information is incorporated using the Cox’s proportional hazard model with the Lindley model at the timedependent component. Simulation studies are performed to assess the size and power of tests of hypotheses on parameters arising from maximum likelihood estimators of parameters in the Lindley model. Results are contrasted with that arising from Cox’s partial maximum likelihood estimator. The Linley model is used to analyze a publicly available data set and contrasted with other models.

Joint Modeling Of Treatment Effect On Time-To-Event Endpoint And Safety Covariates In Control Clinical Trial Data Analysis, Kao-Tai Tsai, Karl E. Peace

Biostatistics Faculty Publications

It is a common practice to perform a separate analysis of efficacy and safety data from clinical trials to estimate the benefit and risk aspects of a particular treatment regimen. However, by doing so, one is likely to miss the complete picture of the treatment effect given that these data are generated from the same study subjects and therefore most likely will be correlated. Therefore, it is desirable to analyze these data jointly to obtain a more complete profile of the treatment regimen. A substantial number of statistical methodologies have been proposed in the last decade to model the time-to-event …

Unsilencing The Voice Within: Expressive Writing As A Therapeutic Tool, Karla L. Sapp

National Youth Advocacy and Resilience Conference

Written words are a very powerful tool that is used to facilitate self-healing, awareness, and growth through the communication of one’s deepest thoughts, emotions, and desires. The purpose of this poster session is to provide mental health providers (community, school, criminal justice) with an overview of expressive writing, forms of expressive writing that can be utilized, and implications for professional practice with At-Risk Youth.

Differences In Health Literacy Knowledge And Experiences Among Senior Nursing Students, Sharon S. Williamson, Joanne Chopak-Foss

Community Health Faculty Publications

Background: Low health literacy has been identified as a significant public health problem. Also, higher expenditures due to longer hospital stays have been reported for persons with low health literacy. Nurses can assist patients with low health literacy to reduce their hospital stays and increase compliance with discharge instructions.

Methods: A quantitative, descriptive research design was employed to assess knowledge and experiences of 192 senior nursing students. These students were administered the Health Literacy Knowledge and Experiences Survey (HL-KES), a 2- part survey that included assessment of knowledge about health literacy and experience in working with populations of …

Inequalities And Approximations Of Weighted Distributions By Lindley Reliability Measures, And The Lindley-Cox Model With Applications, Broderick O. Oluyede, Macaulay Okwuokenye, Karl E. Peace

Biostatistics Faculty Publications

In this note, stochastic comparisons and results for weighted and Lindley models are presented. Approximation of weighted distributions via Lindley distribution in the class of increasing failure rate (IFR) and decreasing failure rate (DFR) weighted distributions with monotone weight functions are obtained including approximations via the length-biased Lindley distribution. Some useful bounds and moment-type inequality for weighted life distributions and applications are presented. Incorporation of covariates into Lindley model is considered and an application to illustrate the usefulness and applicability of the proposed Lindley-Cox model is given.

How Long Does That 10-Year Smoke Alarm Really Last? A Survival Analysis Of Smoke Alarms Installed Through The Saife Program In Rural Georgia, Haresh Rochani, Valamar Malika Reagon, Steve Davidson

Biostatistics Faculty Publications

Background: When functioning properly, a smoke alarm alerts individuals in the residence that smoke is near the alarm. Smoke alarms serve as a primary prevention mechanism to abate morbidity and mortality related to residential fires.

Methods: Using survival analysis, we examined the length of operability of 10-year lithium battery powered smoke alarms installed through the Georgia Public Health/CDC SAIFE program in Moultrie, Georgia. Attempts were made to reach all homes in the city limits. The premise of the study is that geographic clusters (in the case of Moultrie city quadrants) are associated with decreases in the length of time that …
