I am looking for a sun exposure questionnaire to use in a shift work population. Vitamin D levels will be drawn along with the study. Does anyone have a good recommendation?
I did find this, however, there were no references or any indication of validation with it. Does anyone recognize this and could you point me in the right direction to find more information on this questionaire or recommend a different one? In advance, Thank you! Julie
One of my students used a validated questionnaire for sun exposure (aatached) - it seems simple to me but nevertheless was validated. Good luck with your study.
