Quantitative Survey Methods

SOKO Institute uses a multitude of elaborated quantitative survey tools within its empirical surveys and combines them continuously with the “Mixed-Mode-Design” in order to be able to react to conditions and challenges in the respective studies at the best possible rate.

We offer:

  • Computer-based telephone surveys (CATI): CATI (Computer Assisted Telephone Interview) indicates the computer-based support of telephone interviews. With this program, the correct process logic and the screen presentation of questionnaires are implemented. In addition, data is managed and statistics are processed for further usage. CATI-program is able to make study-specific sample selections and navigates the entire appointment management.
  • Face-to-Face-Interviews (F2F): Personal Face-to-Face-Interviews can be conducted with either special computer-based support (CAPI) or without computer-based support (in form of Paper & Pencil-Interviews). SOKO Institute has sufficient capacities in order to conduct regional and nationwide sample testing itself. For supra-regional and nationwide samples, the Institute works in cooperation with partner institutes, based on trusting and long-lasting relationships. The advantages of this type of survey lie in autonomy of choosing place and time for survey implementation and the opportunity to conduct long and in-depth interviews, on, for example, particularly straining topics.
  • Surveys in Written Form (PAPI): Interviews in written form can be either conducted via conventional mail or via self-completion on site.
  • Online Surveys (CAWI):Computer-based web-interviews/ web-surveys, intranet-surveys with and without multimedia support, direct encryption, program-administered implementation
  • Mixed-Mode-Surveys: Through a target-group-oriented selection and an optimal composition of different survey methods, a survey can be particularly efficiently conducted and the response rate can be increased. SOKO Institute choses and uses various survey methods that conform distinctively to the varying demands of respective projects.
  • Classroom Surveys: Interviews with High school students, University students and other groups (including permit applications, recruiting, coordination and contact)

Qualitative Survey Methods

The whole spectrum of qualitative empirical research methods belongs to our services. Many research questions demand a qualitative and explorative approach. In-depth narrative and guideline-based interviews of experts and political decision-makers, group discussions and focus groups, participatory observations and workshops are used in particular.

We offer:

  • In-depth interviews / Expert-interviews: Narrative and guideline-based in-depth interviews including preparation, contacting, implementation and qualitative content-analytical evaluation
  • Group Discussion / Focus Groups : Recruiting, implementation and documentation of target-group-oriented group discussion and focus groups with latest video and sound technology in Bielefeld and the whole of Germany
  • Participatory Observation: Non-inversive and experimental data collection techniques for the exploration of specific target groups (e.g. infants) and situations / settings
  • Workshops / Seminars: Target-oriented workshops and seminars with members of research staff and specific target-groups for the formulation of regulations and “best-practice” recommendation and guidelines
