Collaborative Data Services

Telephone recruitment and survey research (Interviewing Core)

We perform telephone data collection using computer-assisted telephone interviewing tools. Our system optimizes data quality and efficiency using built-in quality assurance features. Interviewing occurs six days a week (with the addition of Sunday calling an option), and our automated call-management software ensures that respondents' participant contacts are spread out throughout the day and week. Our bilingual staff has been trained in interviewing methodology and has experience in dealing with a wide range of patient populations. Please see Interviewing Core for more details.

Mail surveys and self-administered questionnaires (Data Control Core)

We have extensive experience designing and administering questionnaires, and our goal is to design instruments that maximize comprehension and response, to minimize missing data, and to create a data collection instrument that is easy and efficient to use. We routinely supply feedback to investigators about survey readability and ease of use, can pretest your surveys, and can help you to refine your surveys.

We have completed numerous study mailing projects, both large and small, and including mailing specimen collection instructions and sampling kits to participants.

Data entry services (Data Control Core)

We perform data entry services either into pre-existing databases, or in databases that are custom designed by our programming staff. We can perform double data entry for your entire sample, or at a pre-specified rate such as 10-20%, depending on your budgetary restrictions.

We offer a variety of other services (at an hourly rate) including:

• Document Scanning
  
• Filing
