18. Workshop of the Center of Qualitative Psychology

Due to the Corono Crisis the upcoming Workshop in Melilla had to be postponed – new provisional date end of September or October 2020.


AQUAD 8 for qualitative and quantitative text analysis (free/open source), complemented by separate modules for the analysis of sound recordings, videos, and graphic material, was  revised using LAZARUS 1.8.4 / FPC-Version 3.0.4. The version for Windows of AQUAD 8 shows, prints, copies, etc. results with the built-in editor „notepad.exe“. Numeric results (eg., code frequencies or word frequencies) are stored in CSV-tables.

The separate module  aquad-eda.exe  contains software scripts in „R“ for exploratory data analysis.

Due to the revision the software is now in principle running also  on Linux and Mac-OS machines, however the source code still needs some adaptations (eg., definitions of directories; integration of an alternative text editor) and, of course, it has to be compiled on these platforms.

If you are interested to assist in transporting AQUAD 8 to Linux and Mac-OS you are invited to join a team and to ask for the source code.


AQUAD 7 is open-source freeware (according to the conditions of GNU GPL v.3). A full feature list of AQUAD 7 can be found on the informationen and features page. The recent version 7.5 allows to analyze all kinds of qualitative data:

  • within the framework of the code-paradigm,
  • with Boolean minimization to identify types and
  • by means of textual sequence-analysis to reconstruct case structures based on strict hypothesis testing (following the approach of objective hermeneutics).
  • An interface with the statistical software „R“ (open source) allows to combine qualitative and quantitative analyses; the scripts were modified and more scripts were added to version 7.3.

AQUAD supports the following data types:

  • texts of any kind (e.g. transcripts of social interactions, letters, documents, …)
  • audio-data (e.g. interview recordings)
  • video-data (e.g. observations)
  • pictures (e.g. photos, drawings)


Stepwise we will add more pre-constructed scripts for the open-source statistical software package R, which will enable users to realize combined quantitative-qualitative analyses. Besides pre-configured analyses, the plugin offers to use one’s own written R scripts.
