Computer Assisted Instruction Weight Management for Low Literacy Populations Clinical Trials Facts presented on Clinical Trials Search isn't designed to be a substitute for proven healthcare advice, calls or treatment by using a genuine medical doctor. We aren't mDs. Always confer with your doctor on Computer Assisted Instruction Weight Management for Low Literacy Populations conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Computer Assisted Instruction Weight Management for Low Literacy Populations Clinical research trials and Computer Assisted Instruction Weight Management for Low Literacy Populations healthcare trials occur in a lot of of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectivity of new does drugs. The role of the studies / undertakings is to solve specific human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector companies to find treatments for all kinds of conditions, including Computer Assisted Instruction Weight Management for Low Literacy Populations. Computer Assisted Instruction Weight Management for Low Literacy Populations Clinical Trials and other clinical trials allow for volunteers to access health treatment choices before they are available to the general public. Many times the test subjects get treatment for without cost, and sometimes they are compensated for their time. Occasionally there is a cost for a Computer Assisted Instruction Weight Management for Low Literacy Populations clinical trial. Test subjects typically receive the most effective healthcare possible for their Computer Assisted Instruction Weight Management for Low Literacy Populations condition. Risks are a reality, nonetheless, and could include extra or frequent dr. calls, health hazards (perhaps life-jeopardizing), and/or the treatment being ineffective. Trials are federally regulated with rigid guidelines to protect clinical trials subjects.

Computer Assisted Instruction Weight Management for Low Literacy Populations
For Condition: Heart Diseases,Cardiovascular Diseases,Obesity
Status: Completed
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: To develop and evaluate a computer assisted instruction (CAI) weight management program in an adult population with low literacy at Sheehan Memorial Hospital's Family Care Center (FCC), an outpatient clinic serving the inner city of Buffalo, New York.
Details: BACKGROUND: This was the first study in patient care informatics in which nutrient analysis methodology was used on a day-to-day basis to motivate low literate individuals to improve their food choice behavior and physical activity. The deliverables of this investigation included revised and enhanced software, professional documentation, and a participant workbook. These materials were designed so that they could be integrated into any risk factor reduction program for low literacy populations. DESIGN NARRATIVE: The CAI featured voice recognition, giant cursor movement, and a graphics-based environment using pictures to facilitate an exceptionally easy to use and understand software program and booklet. The voice recognition technology was linked with compact disk read only memory (CD ROM) to visually display food choices and physical activities for ease of recording data by the individual. The software was formatted so that health professionals could select preference levels which corresponded to the motivational level of the individual. The four-session CAI intervention had two planned maintenance sessions. The output was personalized and in color. It was designed to identify problematic foods in the diet, improve food selections, and increase physical activity. Stars were printed for adherence to individual goals. One hundred and fifty (150) men and 150 women, between age 20 and age 44, with a reading level of 8th grade or less, who were between 20 percent and 40 percent over their ideal body weight, were randomly assigned to three groups. The design compared a control group without the intervention, a group experiencing the CAI intervention and hands-on computer use, and a group experiencing the intervention but not the CAI component or computer use. All groups were pretested, posttested, and follow-up tested at six months and twelve months following baseline. The primary outcome measures were weight loss, nutrient intake, and physical activity. Data were analyzed using a two-way analysis of covariance and appropriate t-tests.
