ABSTRACT

It is estimated that 43% of United States population is functionally illiterate [1]. On the other hand, the health system in United States is budding and people are being more health conscious and aware. The big question is how we can integrate the healthcare awareness in the illiterate people such that they can also take advantage of the evolving healthcare. In this paper, we present a study to analyze the effectiveness of a new iPad App designed to help low literacy adults manage health awareness.
Keywords

Low-literacy, experimental design, paired t-test
INTRODUCTION

Researchers have investigated that illiterate people are at high risk of poor health because they lack knowledge and understanding of medical information [1]. The low literacy adults have difficulty interpreting the medical information correctly and following the directions of medical information. This is a cause of concern looking at the 43% illiteracy rate in US. Lately there has been wide use of tablet devices and smartphones in low literacy groups. There is an increase in smartphone ownership and usage based on two recent Pew studies [2, 3] in low literacy groups. Hence we decided to use smartphone and tablet devices to increase health awareness in low literacy groups. We designed an iPad app to help low literacy adults increase health awareness. METHODS

To study the effect of iPad App, we recruited 81 low literacy adults. We greeted each participant, explained them the purpose of the experiment and obtained the informed consent at the beginning of the experiment. We started by giving a pre-health awareness test to all the participants at the beginning of the program. Then we explained them about the new iPad App which uses icons for users to input information about their food consumption and exercise. The iPad app

    Experimental Design and Quasi- Experimental Design Cherry Spelock Ohio University An experimental study is defined by the way a researcher manipulates independent variables to prove or disprove a hypothesis. Outcomes are then measured and recorded. Experimental studies are considered one of the most valid ways of determining causal relationships (Byiers, Reichle, & Symons, 2012). When the independent variable cannot be controlled or other factors important to the study are out of the…

    Experimental design is a research method in which researcher tries to examine causal effects by manipulating independent variable under controlled settings and measures whether it produces any change to the dependent variable. In an experiment experimenter deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response. This differs from an observational study, which involves collecting and analyzing data without changing existing conditions. In an experimental…

    A fundamental characteristic of experimental approaches in relation to psychological studies is that researchers can observe and analyse certain behaviours in an environment of that they can control. By exposing participants to certain treatments or conditions, researchers are able to attain identification of causality. There are two primary designs in which experimenters can construct said treatments or conditions. In a “within-subjects” design experiment, all participants are exposed to every…

    Critical Appraisal of a Quasi-Experimental Design Nursing research is an essential part of a nurse’s profession; it has a remarkable influence on current and future evidence-based practice (Tingen, Burnett, & Murchison, 2009). Therefore, it is vital that nurses develop the skill of critiquing a research paper to know how to read and understand those reports. Because evidence-based practice is embedded in the foundation of nursing, it is vital that nurses develop the ability to recognize research…
