Services

UWSC provides extensive and expert consultation about study and survey design as we collaborate in developing customized cost proposals for investigators. Discussions include sampling frame, survey mode, sample size, incentive structure, locating and contacting strategies, achieving high response rates.

UWSC staff are skilled in designing and reviewing survey questions to ensure that they incorporate best practices to yield the highest quality data. We conduct reviews of questionnaires as part of a larger data collection project, and we also offer questionnaire review services for projects in which the UWSC is not collecting the data. In addition, we provide questionnaire layout services for paper and web-based surveys.

UWSC maintains a professional staff with the ability to translate, program, and implement Spanish-language survey instruments, as well as supporting study materials such as advance letters and brochures.  UWSC conducts Spanish-language data collection in all modes, including web, mail, telephone, and face-to-face.

UWSC has experience directly collecting various biological samples and physical measurements, including urine, hair samples, blood pressure, salivary DNA, stool samples, home water samples, gait speed, chair rise, grip strength, lung capacity, vision tests, weight, height, and photographs of respondents.

UWSC obtains and updates telephone numbers, email addresses, and mailing addresses of sample members using state-of-the-art locating tools, including nation-wide credit bureau databases, fee-for-service locater websites, professional web-based information resources, and other sources. We achieve high response rates with challenging populations and in longitudinal studies.

Data entry can be provided in conjunction with a mail survey or as a stand-alone project.  Our staff is capable of handling thousands of entries per week.  We offer single-pass or double-pass entry.  Mail surveys are scrupulously logged and data entered in a project database by trained data entry operators.  Rigorous quality control is performed at each step of the process.

UWSC’s trained coders work in specially designed software to code open-ended survey responses, occupation and industry, interviewer-respondent interaction, and historical census data on microfilm.  Coders work in pairs, double-coding each other’s work, with any discrepancies resolved by a supervisor.

Qualtrics and our own software offer customized questionnaires.  Survey invitations can be sent by letter or email (including reminder emails), and we offer web in mixed-mode surveys with mail follow-up. Electronic files and data are stored on secure servers. Survey data are delivered in a labeled and formatted data set.

All phases of mail surveys (questionnaire design and formatting; mail and logging; data entry and delivery). Design materials and sequence of incentives and contacts (e.g., advance letter, questionnaire, and reminder) for high response rate. Can use researcher’s sample or purchased address-based sample. Tracking and quality control at all stages.

The UWSC call center conducts computer-assisted telephone interviews (CATI). We program simple or highly complex instruments. Interviewers are highly trained and monitored. Digital recording available. Researcher’s sample or purchased sample (landline and cell) can be used. Data available in various formats and can include tools for making data web-accessible.

UWSC conducts computer-assisted personal interviews (CAPI). We program simple or highly complex instruments. Interviewers are highly trained and monitored. Digital recording available. Researcher’s sample or purchased sample (address-based) can be used. Data available in various formats and can include tools for making data web-accessible.

Surveys commonly combine interviewer-assisted modes (face-to-face and phone) with contacts by mail and self-administered instruments (paper and web). We customize survey designs to consider information in the sampling frame and combine modes for cost-effectiveness and high response rates.

UWSC builds both Android and iOS data collection apps. These apps can be installed on  both UWSC-owned and respondent-owned devices. Data are stored locally on the device if no internet connection is available and synchronized back to secure UWSC servers when an internet connection exists.

UWSC has over 15 years of experience with programming computer-assisted self-interviews (CASI) and audio-computer assisted self-interviews (ACASI).  These instruments are primarily used as modules within a face-to-face interview but can be developed as a stand-alone instrument.

All of UWSC’s telephone interviewing stations (for CATI) and our encrypted laptops (for CAPI) are equipped to digitally record interviews.  This powerful and flexible technology integrates seamlessly with our interview software and allows us to record interviews in their entirety, or if preferable, only certain sections of an interview.
