Dear Carolin,

Welcome to this excellent list. You tell us a little about your
intentions in this study but not enough for us to see the minutiae of
the connection between those ideas and the grid design you have (very
shrewd) concerns about. That limits the detail we can give so you
might like to say a bit more about how you are intending to analyse
the grids and link that to your intentions. However, my thoughts at
this stage are:
a) you're right to be worried
b) I have known postal completion of triadic elicitation of grids but
it is pushing your respondents collaboration hard and the grids
in question were much smaller and the respondents quite motivated
c) the grid _IS_ large

I would wonder whether you can't use a fixed construct grid but
obviously that sacrifices most of the flexibility of the technique
(though it can open up new avenues in a very useful way). Failing
that I'd recommend a smaller grid (8x8 to 10x10 or thereabouts) and
dyadic or even single anchored elicitation or even some non-element
anchored elicitation.

Do you feel you can tell us more about the study?
