Reviewer's report:  
 
Dear authors,  
 
Despite your study is very interesting in order to know the causes of non -compliance 
colonoscopy, it is needed to take into account:  
a) The period of patient inclusión is very wide  
b) Possible bias of memory  
c) Have the questionnarie validated?  
d) The sample es very small  
e) It is very important to give data about the lesions detected in people who performed 
the colonoscopy.  I understand most people follow -up the colonoscopy after a positive 
result.  
f) Some ref must be checked
