Screening questions are asked before you a company sends you a survey to complete. These questions will help the researcher determine if you are a good candidate for the survey.  You are either screened out or allowed to complete the survey depending on your answers.  If you are screened out, you are not paid for your time to complete the screening questions. If you are screened in, you will be asked to complete the full survey for the specified compensation disclosed when you received the initial survey invitation.
