Liberty Research Services, LLC has a staff of trained professional interviewers to conduct in-store/on-site consumer intercept interviewing.
All interviewers are briefed by a field supervisor prior to each project to insure that respondents are screened and questions are asked according to a client's specifications.
Our interviewers are trained to screen respondents according to specs and to read the questionnaire the way the client has intended. This means paying special attention to screeners, quotas, skip patterns, open-ended responses, and correctly following interviewing prompts.
