Expert Staff

DSG research staff and consultants are highly experienced in both quantitative and qualitative research methods, including survey design, instrument development, telephone and in-person interviewing, survey operations, site visits, and analysis. We do not use “cookie cutter” methodologies. Rather, we tailor our approach to clients’ needs, seeking to include the combination of quantitative and qualitative methods that will best capture the full range of needed information, whether the task at hand is a formative study of a new program, an accountability study for stakeholders, a process study assessing program implementation, a study of program coverage (e.g., program targets, bias, and over- or under-inclusion), or program monitoring.

Survey Methodology

Research studies have entailed the design of surveys to assess attitudinal, behavioral, and opinion changes (including random and stratified sampling plans on national and local levels); development of data collection instruments for in-person and telephone interviews as well as secondary data analysis; qualitative research strategies (including interviewing, ethnographic mapping, focus groups, and participant observation); site-visit protocols; development of interviewer training manuals and programs; data collection; database development; data analysis; and production of final reports.

To ensure methods are cost-effective and appropriate, each step of the research process is monitored closely, from the preliminary analyses and specification of hypotheses to the selection of the type of study and study design, and the identification of controls and outcome measures.
