RTI International (RTI), a non-profit research organization, is recruiting people to participate in an opinion survey pretest. You will be asked questions about your preferences for possible non-metastatic castration-resistant prostate cancer (NM-CRPC) treatments. If you are 18 years of age or older, have been told by a doctor that you have NM-CRPC, you may qualify. The interview will take an hour, and you will be paid £70 if you are eligible and selected for the interview. Please contact firstname.lastname@example.org to see if you are qualified for the interview.
