Repertory grid technique

Draft

Definitions

“The Repertory Grid is an instrument designed to capture the dimensions and structure of personal meaning. Its aim is to describe the ways in which people give meaning to their experience in their own terms. It is not so much a test in the conventional sense of the word as a structured interview designed to make those constructs with which persons organise their world more explicit. The way in which we get to know and interpret our milieu, our understanding of ourselves and others, is guided by an implicit theory which is the result of conclusions drawn from our experiences. The repertory grid, in its many forms, is a method used to explore the structure and content of these implicit theories/personal meanings through which we perceive and act in our day-to-day existence.” ( )

“The term repertory derives, of course, from repertoire - the repertoire of constructs which the person had developed. Because constructs represent some form of judgement or evaluation, by definition they are scalar: that is, the concept good can only exist in contrast to the concept bad, the concept gentle can only exist as a contrast to the concept harsh. Any evaluation we make - when we describe a car as sporty, or a politician as right-wing, or a sore toe as painful - could reasonably be answered with the question 'Compared with what?' The process of taking three elements and asking for two of them to be paired in contrast with the third is the most efficient way in which the two poles of the construct can be elicited.”.

“The repertory grid technique is used in many fields for eliciting and analysing knowledge and for self-help and counselling purposes.” (Repertory Grid Technique, retrieved 10:59, 26 January 2009 (UTC).)

Overview

Feixas and Alvarez

According to Feixas and Alvarez, the repertory grid is applied in four basic steps: (1) The design phase is where the parameters that define the area of application are set out. (2) In the administration phase, the type of structured interview for grid elicitation and the resulting numerical matrix is defined. (3) The repertory grid data can then subjected to avariety of mathematical analyses. (4) The structual characteristics of the construct system can then be described.

“The elements selected for the grid depend on which aspects of the interviewee's construing are to be evaluated. Elements can be elicited by either asking for role relations (e.g., your mother, employer, best friend) or by focusing on a particular area of interest. A market research study might, for example, use products representative of that market as elements (e.g., cleaning products, models of cars, etc.).”(http://www.terapiacognitiva.net/record/pag/man2.htm Design Phase])

“The type of rating method used (dichotomous, ordinal or interval) determines the type of mathematical analysis to be carried out as well as the the length and duration of the test administration. As before, the criteria for selection depend on the researcher's objectives and on the capacities of the person to be assessed.” (http://www.terapiacognitiva.net/record/pag/man2.htm Design Phase (2)])

Feixas and Alvarez then outline three methods to elicit constructs:

A) Elicitation of constructs using triads of elements. This is the original method used by Kelly. It involves the presentation of three elements followed by the question, "How are two of these elements similar, and thereby different from a third element?" and then "How is the third element different from the other two?" [...] B) Elicitation of constructs using dyads of elements. Epting, Schuman and Nickeson (1971) argue that more explicit contrast poles can be obtained using only two elements at a time. This procedure usually involves an initial question such as, "Do you see these people as more similar or different?" This prompt can then be followed by questions of similarity such as, "How are these two elements alike?" or "What characteristics do these two elements share?" Questions referring to differences such as "How are these two elements different?" are also appropriate. [...]

C) C) Elicitation of constructs using single elements. Also known as monadic elicitation, this way of obtaining constructs is the most similar to an informal conversation. It consists in asking subjects to describe in their own words the "personality" or way of being of each of the elements presented. The inteviewer's task is limited to writing down the constructs as they appear and then asking for the opposite poles.

In knowledge engineering

The technique discussed by Nick Milton (Repertory Grid Technique) includes four main stages.

• In stage 1, elements to analyse (e.g. concepts or observable items such as a pedagogical designs or roles) are selected for the grid. A similar number of attributes that allow to characterize each element are also defined.
• In stage 2 each concept must be rated against each attribute.
• In stage 3, a cluster analysis is performed on both the elements and the attributes. This will show similarities between elements or attributes.
• In stage 4, the knowledge engineer walks the expert through the focus grid gaining feedback and prompting for knowledge concerning the groupings and correlations shown.

Software

• Gridcore Correspondence analysis tool
• Many statistics programs can do cluster analysis, e.g. SPSS.
