Health Tests (similar to Personality Tests)
Many websites offer their Participants the ability to take health tests, Stan Kaufman (another openacs developer), has written an excellent example of health tests on OpenACS3.x demos of which are available at http://www.cvoutcomes.org. In these surveys one asks a number of questions and then come up with an estimate of risk for certain health concerns. Each question is part of a subsection of the primary survey. So, for example one may ask 10 questions about a persons diet, 10 questions about a person physical activities, 10 questions about a family history of disease, etc. At the end of the survey, it would then respond to these sections and say "it looks like you need to eat a more balanced diet", "you seem to be above average in terms of physical activity so keep it up", and "since your family has a history of concerns with this disease you should be extra cautious and be sure to inform your doctor that they should check for any irregularities". One could also envision a scenerio in which these three responses woudl be given and a summation would also be given, something like "since you are below average in 2 of the 3 categories you are at risk for ________ disease".
Luckily these customized responses and categorization are equal to the "scored surveys" translation from points to scores. I have suggestions for data model modification to accommodate these systems below.
