Q-Sort Resources


Q-sort Decks

The three elements of the "personality triad" are the person, the situation, and behavior.  The Riverside Accuracy Project uses Jack Block's personality Q-sort (adapted) to describe persons (the California Adult Q-sort or CAQ), the Riverside Behavioral Q-sort to describe behaviors, and the (new) Riverside Situational Q-sort to describe situations.  To see the items of these instruments, follow the links below.


California Adult Q-sort (CAQ)

   This instrument for the comprehensive description of personality was developed by Jack Block and revised for use by non-professionals by Bem and Funder (1978).  

   Nearly all of the publications from our lab using the CAQ have used this revision; to see the items click here.

    More recently, Block (2008) published a revised version of the CAQ, clarifying and simplifying much of the language.   In 2012, Esther Guillaume and David Funder revised this version further, to make it easier for non-psychologists to understand and to facilitate translation into other languages.  To see this version, click here.  Please note that this version is not the one included in the computer file listed below.


An excellent resource on the basis of the CAQ, and about Q-sorting in general, is the updated version of Jack Block's classic book.


Riverside Behavioral Q-sort (Version 3.11)

   This is a revised version designed to be more broadly useful outside of the experimental settings in which the original versions were employed. 


Riverside Situational Q-sort Version 4.0

This latest version, with 90 items, was written to be more easy to translate into languages other than English and to cover aspects of situations that might be relevant to cross-cultural comparison.


Riverside Situational Q-sort Version 3.15

Most recently published research uses this version, which has 89 items.

For an older version (RSQ 2.0) used in some past research, click here.



The RSQ and the RBQ have been translated into many languages other than English (so far).  You can access some of the translations using the links below.

Q-sorter Program


The Riverside Accuracy Project Q-Sorter Program is available for download. We strongly recommend that you download and read the instruction manual before attempting to use the program. This program requires the use of a PC running either Microsoft Windows 2000 or Windows XP. This program will not work on a Mac or computers running older versions of Windows.  Apparently it does work with Vista, if all the latest updates are installed.  As Windows continues to be "improved," this program may become non-functional and we are currently working on a replacement.

In addition to installing the program you will need to have Microsoft DotNet framework installed (see below for link).

Note: This program is becoming more difficult to use over time as Windows continues to issue new versions and drops support for programs that worked on earlier versions.  In an attempt to circumvent this problem, a web-based version of the Q-sort program is currently under development.


This program is offered to you to use free of charge.  See the important disclaimers below.

To download the files using Internet Explorer, right click on the file name and select "save target as..".
