Hello everybody, 
If anyone has any advice or information on valid questionaires for 
the assesssing the following, I would be very grateful.
1) Self assessed health 
2) Self assessed exposure to environmental risk factors 
I am interested in designing a study which examines factors which 
lead to response bias in exposure assessment.  Potential factors 
include perceived health,  media exposure, locus of control, and 
If anyone is aware of current research in this field, or can 
recommend anyone to contact, that would be fabulous.
Thank you.  Mike Hogan (research fellow, UCG, Ireland)
