Kelly (1955) developed personal construct theory andan associated method ofdata collection and analysis, therepertory grid, which are both in widespread use in ex­perimental and clinical settings. Since Kelly's originalwork, repertory grid technique has been elaborated in avariety ofways (Adams-Webber,1987). Virtually all ofthe resulting techniques are amenable to automation. Oneapproach, a computer program called OMNIGRID, is de­scribed in this report.OMNIGRID is a public domain program that allowsthe user to choose from a wide selection ofgrid techniques(Mitterer & Adams-Webber,1988). It is primarily com­posed of three major subprograms: Configure, Col­lect, and Analyze. OMNIGRID was designed to begeneral, reliable, and valid. Generality has been achievedby placing the program in the public domain, allowingthe selection ofmany ofthe currentlyavailable repertorygrid options, and supplying full documentation to allowrelatively simple modification and translation to other ver­sions of BASIC. Reliability and validity have beenachieved by including only testing and data analysismethods ofestablished reliability and validity.Input. The program requires two distinct types ofin­put, that from the experimenter or clinician and that fromthe subject or client. The experimenter or clinician willuse the Configure subprogram to design a repertory grid.Basically, the subprogram asks the user between 10 and30 questions (from a set of47) relevant to the design ofa repertory grid. This subprogram, which is the heart ofthe OMNIGRID system, allows the design ofa repertorygrid, complete with a specification ofconstructs and ele­ments, method of presentation, and desired data analyses.A manual and an on-line help file areavailable to guidethe user through this portion ofthe program. Some of theoptions currently available include the following:Content:
