we are epidemiologists of the Italian National Research Council interested in exploring the potentiality of INTERNET for performing some epidemiological investigations at international level. As far as we know it is the first attemp of this type in epidemiological research. If you are interested in joining, you are kindly requested to fill in the following questionnaire for one day (at your choice) in the week 27 March - 1 April 1995 and send it back to (EPID@CNUCE.CNR.IT). We will pleased to answer any questions concerning the results of the investigation (a gopher named "EPID.CNUCE.CNR.IT" will be available at the IP port =7000). Before people reply to this, they should think about this: - Normally answers to this sort of investigations are given anonymously. With answers via e-mail this is impossible, since e-mail addresses can always be tracked back to a person. How are you going to deal with that? - What is the purpose of the investigation? You say that it is for "exploring the potentiality of INTERNET" for this sort of investigations, but the questions posed indicate quite a different purpose: - investigation on the use of PC's and VDT's; - investigation on medical issues; these *seem* related to the use of PC's and VDT's, but an item like "Number of occasions in your lifetime" (for seeing a physician or taking medicines for ...) contradicts this. - Who is going to handle the raw data? Is there any guarantee that they won't fall into the wrong hands (given that they can't be anonymous)? Oh, and most of Europe measures in centimeters, not inches...
