Scale Types

Idiogrid employs a number of different scales. The user can select each type of scale for the grid elicitation and manipulate a number of its features. For instance, up to 9 categories can be defined for Likert-type scales and their labels can be edited, a 'does not apply' option can be toggled on or off for most scales, and the item stems can be edited. Additional options are also available, and Idiogrid also included a novel type of scale referred to as the Dynamic Analog Scale. Example of the different types of scales follows:

A process by which the elements are ordered from greatest to least on each personal construct or dimension.  For example, a person may be asked to rank 'mom', 'dad', 'self', and 'brother' with regard to their overall happiness in life. The person may rank 'mom' as happiest (rank = 1), 'brother' as second most happy (rank = 2), 'Dad' as third most happy (rank = 3), and 'self' as the least happy person of the group (rank = 4). 


A new scaling procedure included in Idiogrid in which the participant simultaneously rates various targets (usually people) on a continuous scale anchored by adjective terms. The administrator determines the anchors for the scales and can also provide extended definitions of the scale anchors. The data that results from the rating procedure will range in value from -200 to +200. A screenshot of this novel scale can be seen here .

A short video describing how to use the DAS is also posted here. One bit of information the video omits, however, is that a target can be removed from the rating scale by clicking the target with the right mouse button. Also, not all targets must be rated on the scale for the user to proceed through and to complete the procedures.
