Data Collection
CSR conducts surveys by mail, the web and other data collection modes. Data collection staff receive a thorough program of training in data collection procedures, and their performance is evaluated systematically by supervisors. The aim of these efforts is to maximize participation, response rates, and data quality.
CSR conducts large-scale national as well as regional surveys, with sample sizes ranging from less than a hundred to many thousands of surveys. CSR is experienced in interviewing specialized populations, such as physicians and CEOs, the elderly, children, the very ill, and disadvantaged or hard-to-reach urban populations. CSR conducts many self-administered mail surveys, following standardized protocols including postcard follow-up, second mailings, as well as push-to-web mailings. All completed self-administered mail surveys are double entered and verified. CSR has conducted a number of web surveys with specialized populations and is experienced with increasingly popular mixed-mode data collections.
Focus Groups and Cognitive interviews
CSR conducts focus groups and in-depth interviews, both as primary data collection mechanisms and as steps in the questionnaire development process. We have conducted focus groups with many special populations, including physicians, cancer patients, as well as general population groups. In addition, a number of our research staff as well as our interviewers are trained to conduct in-depth cognitive interviews to understand how respondents answer survey questions. The goal of these activities is to determine whether or not drafted questions present tasks that respondents can perform, are consistently understood in the way they were intended, are measuring what they're designed to measure, and can be administered in a standardized way. CSR can conduct focus groups and cognitive interviews in-person or by video, using a service such as Zoom.
