摘要

In this paper the authors aim to discuss a series of surveys conducted over the past two years through web-survey, through which issues related to eating disorders have been scrutinized with the objective of giving a portrait as to the several aspects concerning those who live in a state of distress by cause of chronic diseases. The methodology employed makes use of statistical techniques widely recognized in the scientific field. The main purpose is to understand if the new techniques of study born to the web 2.0 are valid as classical techniques, with particular attention to the break-off phenomenon (total and partial dropouts) as well as the response and cooperation rates, in order to understand how these may still be valid in contexts web 2.0. The results are encouraging, the rates examined and the percentage emerged from error sampling makes us think that we snatched the dragonfly on the grass.
