​IMPAQ offers a full range of survey research services to clients in government, non-profit, academia, and the private sector, applying rigorous scientific methodologies to survey design, sampling, survey administration, and analysis, with demonstrated expertise in gathering data on sensitive topics or from hard-to-reach populations.

With expertise in survey methodology, questionnaire design, electronic data capture, and multi-mode data collection, IMPAQ is highly skilled in quantitative and qualitative techniques such as focus groups and in-depth interviews. The firm helps clients achieve statistically significant survey response rates through the use of best practices, innovative recruitment strategies, non-response follow-up techniques, and refusal aversion and conversion.

IMPAQ manages its own full-service, technology-rich in-house survey center, staffed seven days a week with experienced, highly trained interviewers, supervisors, locators, coders, and data processors.

Survey Design, Sampling & Instrument Development

IMPAQ starts survey projects by partnering with clients to fully understand the information requirements of a program or policy investigation. This activity is followed by identifying an appropriate survey methodology and acquiring or building the needed respondent sample frame.

IMPAQ’s survey staff have a wealth of experience in the design and development of survey questionnaires, a critical component of the survey process. Drafted questionnaires undergo cognitive testing, pre-testing, and pilot testing, and all necessary approvals are obtained before the surveys are utilized.

IMPAQ is highly experienced in the Office of Management and Budget development and approval process as well as with 508 requirements and can deliver questionnaires in multiple languages to meet specific needs around the world and in remote locations.

One example of IMPAQ’s ability to adapt survey design and development to information needs is the Kidney Disease Quality of Life (KDQOL) survey, a census of approximately 18,000 Medicare beneficiaries assigned to End Stage Renal Disease Standardized Care Organizations. The survey follows a dual-mode approach – a mail survey with telephone follow-up of non-responders coupled with the KDQOL-COMPLETE™ scoring survey tool, which is offered in 10 languages.

Data Collection & Survey Operations

Today’s survey research efforts often require the use of multiple methods with numerous attempts to reach respondents via landlines, mobile phones, interviews, mail, email, Internet, and mobile field devices. IMPAQ survey staff understand the specifics involved in data collection at this level, including:

  • Which respondents need to be recruited;
  • How best to contact and interact with respondents;
  • What respondent assurances need to be addressed (i.e. confidentiality, anonymity, Family Educational Rights and Privacy Act, and Health Insurance Portability and Accountability Act regulations); and
  • Content sensitivity.

IMPAQ has developed robust, leading edge, multi-mode data collection methods utilizing our in-house, Computer Assisted Telephone Interviewing (CATI)-equipped telephone survey center for cost-effective data collection. Teams of researchers, technologists, and subject matter experts work closely with survey center staff to ensure that the data collected meets the highest professional standards.

An example illustrating these survey capabilities is the National Implementation of the Medicare Consumer Assessment of Healthcare Providers & Systems Fee for Service (FFS) Survey, funded by the Centers for Medicare & Medicaid Services (CMS). This was a multi-year, large-scale data collection effort that involved surveying approximately 275,000 persons enrolled in the Medicare FFS Program across all 50 U.S. States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. The survey was implemented using a mixed-mode methodology that included two paper questionnaire mailings and telephone follow-up for mail non-respondents. The telephone follow-up was conducted using CATI technology. Surveys were conducted in English and Spanish.

Data Analysis & Interpretation

IMPAQ has developed sophisticated data processing systems that enable researchers to clean, organize, and analyze large sets of survey, program, and administrative data, providing clients with clean, well-documented data sets. Documentation includes basic frequency counts for survey variables and sample weights, when appropriate. These materials enable complete use of the survey data by clients for specialized or extended analytic purposes.

Clients often desire detailed analyses of survey data specific to policy or program needs. To meet those needs, IMPAQ can deliver multi-faceted reports, such as those required by state education departments that present findings for each school district or region in a specific state; for federal government programs that require results by geographical regions; or, by state health agencies that require surveillance data by county.

The IMPAQ survey team collaborates closely with our Ph.D. level subject matter experts to summarize and validate findings and identify recommendations for program and policy considerations.
