Computer programmes for the analysis of Repertory Grids

Essential reading

When using the Repertory Grid Technique, it is advised to read the fundamentals:
  • Fransella F, Bell, R, Bannister D (2003). A manual for repertory grid technique. 2nd ed. Chichester: Wiley.
  • Jankowicz, A D (2003) The Easy Guide to Repertory Grids. Chichester: Wiley.
Using SPSS

Repertory Grids can be analysed using procedures that are parts of standard statistical packages such as SPSS. Richard Bell (Melbourne) in an unpublished paper titled "The Analysis of Repertory Grid Data using SPSS" gives recommendations. It can be downloaded here.

Specific programmes

There are a number of computer programmes developed specially for the analysis of repertory grids available that run on PCs. Some are free, some are relatively expensive (up to around 600 US $ for individuals), some are accessible on-line. Most of them offer one or more of the following procedures:
  • a number of indices characterising grid
  • properties of single constructs or elements
  • relationships between single constructs (e.g. as correlations) or elements (e.g. as distances)
  • structural relationships between constructs or elements (factor analysis, principal component analysis or correspondence analysis, cluster analysis, formal concept analysis)
  • structural relationships between constructs and elements (e.g. single value decomposition after Eckart and Young)
The pioneering work was done by the late Patrick Slater in the Sixties. It worked on mainframe computers and was DOS-based. There was no graphical output. It consisted of: 
  • INGRID: "Principal Components Analysis", essentially an Eckart & Young decomposition, construct intercorrelations, inter-element distances.
  • COIN, PREFAN, DELTA: various extensions, e. g. comparison of two grids, joint analysis of several grids etc.
Some DOS based programmes are probably no more in use as WINDOWS has become the dominating operating system:
  • FLEXIGRID, by Finn Tschudi
  • OMNIGRID by Jack Adams-Webber and Kenneth Sewell . 
  • CIRCUMGRIDS, by William Chambers
  • GRIDSTAT and GRIDSCAL, by Richard Bell
WINDOWS based programmes
 
Programmes vary as to the degree the underlying maths is made explicit; some appeal to users who are not interested in the specifics. Some have special prices for use on more than one computer; some offer licences for one year or more. Some have free online versions. Some offer free demo versions with limited capacity. Details are available on the web sites.
