>1) you have used questionnaires or are aware of existing ones--and any opinions >you have on them There is research that has been done on this question. Look in the archives of Journal of Human Lactation, and look in a medical research database. Then you can contact the authors to get copies of their questionnaires. Usually people are willing to share this info with other researchers, because if their questions are good questions that prove reliable, then using them on other studies can help support their findings. Besides it's professional courtesy. Often the basic questions are reported in the articles written about the research, but it's good to get the survey instrument itself if you can. Another place to look is govt research agencies like CDC and others that do surveys. Their questionnaires are in the publice domain, probably on the web, and are usually well tested. It will take some poking around on the web and the library to get the questionnaires but they are out there. >I may end up creating a questionnaire that measures >factors known to influence breastfeeding duration and also includes >measurements of social support. For purposes of reliability and validity you are better off using questions that have already been used and adding a few of your own.
