Definitions for QCA

As announced earlier, we are now in a position to share the definitions we have used in our Qualitative Comparative Analysis (QCA). You can download the definitions as a PDF document by clicking here

The document presents the top-level, aggregated conditions we have employed in QCA. Behind every individual condition there is a host of detailed definitions. We have written up some 60 pages of such definitions, with instructions for the precise measurement of the factors that have entered our analysis. If you have any questions regarding a specific element, please do not hesitate to get in touch via the comments function on this blog.

Our draft Review report is with DFID and the Reference Group now; by mid-June you can expect to find the final product here. 

Furthermore, we are working on two articles - one on the findings, the other one on QCA, for peer reviewed Journals. We'll be in London to present our findings at an event hosted by DFID (date & venue to be confirmed). Michaela will present a poster on our Review findings and how we used QCA in it at the Conference of the European Evaluation Society in Dublin (October 2015). We'll keep you posted!


  1. Hi
    Thanks again for another useful update on your work.
    Three questions, to help those of us following in your footsteps:
    1. You have on aggregate Outcome (strong evaluation effect) made up of 4 types of effects. Why bother with the aggregate level, why not do 4 separate QCA analysis, one per specific effect?
    2. Re the tree diagrams for each condition, how will you aggregate judgements up from the particulars (leaves) to the more general (root)?
    3. Re the figures 2, 4, 5, 6, where are these explained. They look like cutoff points on the scales used to judge each condition, a fuzzy set value, but I may be way off

  2. Unfortunately the link to the definitions file doesn't appear to be working.
