History of questionnaire and myopia

Order Description Actually this order was already done by one of your writers and its number is 81709998 but unfortunately he didn't meet the requirement. So, according to call, which I discussed this issue with your representative, I submit a new order. Please write a chronological report about the use of questionnaires in determining environmental risk factors for myopia. Explain how researchers went from wide range of questions to specific questions, and also focus on specific factors such as time spent outdoors, physical activities and near work. All materials were already uploaded in order number 81709998. Try to track what every researcher asked about and what they found, then move to another one and so on. Here is comments and the structure which is suggested by my advisor: There is currently a lot of useful info but it's rather unfocused. By the end of the section it should be clear what the questionnaire is, why it is formed the way it is which includes where it came from, and why a questionnaire was chosen as a potential measuring instrument. Things you need to cover are General background about questionnaires Basic forms of questionnaires Strengths and weaknesses--bring out strengths Uses of closed and open-ended questions I suggest starting with a short piece on what questionnaires are, and the general forms they can take, with some brief examples to clarify the description. You should also cover forms of delivery e.g. recorded by a researcher, paper and pencil, online, app-based. You need to bring out their weaknesses and strengths. An obvious weakness is that they have to rely on personal reports and opinions. Questionnaires cannot measure light exposure objectively in lux, so you have to substitute measures which people can report which can stand in for lux measurements. In this case, this disadvantage was countered by the particular strength; the ease of collecting large amounts of both demographic and light-exposure data over time, with minimal inconvenience to participants. In this section you can transition from talking about questionnaires in general to this particular questionnaire (in excel sheet file). The key issues are what it asked, and why it asked those things. This part would include a history of previous light-exposure questionnaires (Focus only on outdoor questions), showing the origins of latest one which is WHO questionnaire, but also making clear the differences/modifications. Questionnaires shouldn't contain "fluff". Every question should have a relevant purpose. By the end of the questionnaire section you should have justified why every part of the questionnaire was there.
