PQMethod Software

PQMethod is a statistical program tailored to the requirements of Q studies. Specifically, it allows to easily enter data (Q-Sorts) the way they are collected, i.e. as 'piles' of statement numbers. It computes intercorrelations among Q-Sorts, which are then factor-analysed with the Centroid or, alternatively, PCA method. Resulting factors can be rotated either analytically (Varimax), or judgmentally with the help of two-dimensional plots. Finally, after selecting the relevant factors and 'flagging' the entries that define the factors, the analysis step produces an extensive report with a variety of tables on factor loadings, statement factor scores, discriminating statements for each of the factors as well as consensus statements across factors, etc. The original FORTRAN program, QMethod, was developed by John Atkinson at Kent State University in 1992 for mainframe platforms, and released to the Public Domain. It was ported by the maintainer of this site to the PC and updated with added features to versions 2.xx later on.

PQMethod with the accompanying PQROT is free software, distributed under the terms of the GNU General Public License(GPL).

Other Software Packages for the Analysis of Q-Sort Data

QUANAL
Like QMethod, Norman Van Tubergen's QUANAL is a FORTAN program, developed in the 1960s for mainframe platforms. It is rather complex, and offers a great variety of features and options with respect to input-data structure, methods of analysis and the presentation of results. For further information contact Norm Van Tubergen. <huc129@uky.edu>.
PCQ for Windows
by Mike Stricklin is a commercial factor-analysis program for Q-technique.
General-Purpose Statistical Packages
The big commercial statistical packages like, for instance, SPSS, though highly-featured, user-friendly, flexible, etc. in many respects, do not provide optimal support for entering and factor-analysing Q-sort data. Yet, they may be indispensable for additional statistical procedures not available with QMethod software (e.g., analysis of variance). In practice, therefore, one often needs to use both, general and specialized statistical software, alongside with each other - especially in cases of mixed Q- and R-designs (within-subjects and between-subjects perspectives of analysis). An example that demonstrates how a typical Q analysis can be set up in SPSS is provided in the 'Q Study Archive' (see below).

WebQ is a JavaScript application for Q-sorting questionnaire items online.


Q Study Archive

A (still) small repository with examples of Q study data sets prepared for the various software packages. Where available, program output files are provided as well.
