|Repertory grids are an idiographic measurement system. The grid in the name is just that: typically the columns are things and the rows are adjectives on which the things are rated. In therapy research they have mainly been used with people, including one or more self elements as columns thus collecting a number of ratings of self and of others. For example, self elements might be “self now”, “ideal self”, “self before x”, “feared self” and others might be parents, siblings, friends but also disliked or feared others.|
Repertory grids were invented by George Kelly as part of his “Personal Construct Theory/Psychology (PCT/PCP)”. Grids can be entirely specified (who is rated and on what domains of interest) or they can have significant “user-generated” aspects with the client selecting who to rate and on what dimensions: “elicited constructs”.
