Responses to questionnaires (mobile phones as an example)

["Bjorn Cedervall" <bcradsafers@HOTMAIL.COM>]

I sent out the question about "which ear" to Radsafers plus about 150 other 

people (that is over 3000 people). 28 hours have now passed and I obtained a 

total of 47 responses so far. 20 of these responses come from Swedish 

friends.



Present status:

Right: 11

Left: 16

Both: 17

Don't know: 2



This low response level is interesting in itself - the key reference I have 

in mind (Cellular and cordless phones..., European J. Cancer Prevention, 

Vol. 11, 2002:377-386) say that they had a 90 % response level after sending 

out a 21 page questionnaire.



I am asking only one question and it seems like I may get a maximum of 5 % 

responses if I am lucky.



This doesn't make sense - even if it is only after 24 hours. Can anyone 

comment typical response rates (%) for questionnaires?



For remaining responders - please send your "ear" answer

(right/left/both/don't know)

to

best3d72@yohoo.com



Why is all this important? Because the whole study (ref. above) is based on 

the phone-ear and acoustic neurinoma (benign tumor of the brain). I 

deliberately stay away from any interpretational reasoning at this stage. 

One must be cautious anyway. The more of you who respond - the more valuable 

this survey will be.





My personal reflection only,

(I have now arranged so that an independent person will check all responses 

to "best3d72" - those sent to this email address must be promtly deleted 

however - after writing down the answers of course. There is a heavy 

pressure on this email address so I can't keep any emails for someone else.)
